About This Class

Editing videos for YouTube or Skillshare does not have to be costly.

In this class I show you how I use 3 Open Source tools (Blender, Audacity and Handbrake) for editing my videos, editing audios and then compressing the video files. All these applications are very capable, feature rich and still FREE. They are constantly supported and upgraded by the developer community.

All my online class videos and YouTube videos go through this same editing workflow which I show you here. Though all of these applications have hundreds of settings, I show you exact settings that I use so that even if you do not understand or do not want to understand how they work, these settings will do the work of editing videos for you. You are of course free to try different combinations of settings once you get familiar with the usage.

So if you are a video enthusiast or a online teacher like me, this class will give you lot of information that you can implement right away.

1. Introduction: Hello and welcome. When I first started making videos for my on land forces, I had the impression that video and audio editing tools would cost me hundreds of dollars. But I wasn't a budget, and so I decided to look for open source applications that would do the job for me. Search paid off, and I now make all my video editing or urinating on video compression, using open source tools that cost me absolutely zero bottles in this class and show you how I use Blender two separate audio from my video fights. Audacity. I did the audio blender toe perfectly. Edit the video and most editor audio and finally use hand brake to compress the video. So if you're a video enthusiast or a teacher who teaches using videos, this course will give you a lot of information about free yet powerful tools that can perfectly edit your videos and audio. So let's get started, hit the blue Inderal button and see you in the class 2. Setting Up Blender: Let's start from a place where we assume that you have made the videos using either a camera or an iPhone or some of the device. And then we won't go separate out the audio so that we can edited separately in order City on for that separation we're going to use our tool called blender Blender is a free tool on . You can download it from blender dot org slash download, and once you open it, you see a screen like this and then dough. The blender is mainly used an animation tool, but it also is a powerful video editing and sequencing. Cool. So when you open it, you click on this button here on, you can see various set ups or videos. So but, he said to each other on one of them is the video editing. So click on that and you get a window like this first thing is this window. We want to see the properties so we go here and select the property so that we see the very a sentence which we want to do. Then this is the preview pain where the video will be seen when we are editing a preview off that will be seen here. This area is guard the video sequences in which we can sequence one video after the other. We can cut them at various places which we require for anything. Now let's look at the property's slightly more in detail. Now we want toe have supposed of video, which is off 180 p. That's our true HD. Then we can take this as that on it Sex the X and Y values to 1920 and 10 and zero. If you want tohave 7 20 p output file, then this is more it gives out. So since I will be doing our exporting my video in tow 7 20 p resolution I've selected this precept now coming down there is a setting gold frame Read This frame rate is the frame rate at which you have recorded your video. So if you are right, click on your video and tried toe Jack What frame rate FPs value that is it is recorded. Then you have to set that too. This value suppose typically are canon camera would DSLR camera would recorded down 59.94 onda but all YouTube videos are generally done at 30 FPs. So if you you can check those values using an application called Real C Player or that opened the real simile a player on open a file I'm opening a recent fine on. I want to see the details off this video's I open tools and media information and I goto correct. And here I can see the frame rate is 30 and the display resolution or audio and studio audio sample it'd 44 Gillard's and so So this is the place where you check what is the prem rate at which your video is recorded, and then you can put this value in blender in the very you have to mention the frame rate off the video coming down for the This is the place where you will give the location where your output file should be strolled. So when you click on that, you can select the colder in which you want your files to be stored. So I am making this folder here on. This is where you can write the name of the file, and then it will get school. So he fight. I'd best dot and before and then I accept So the file will be stored as as that you can say that to you coming down. I see that by default the performance is PNG on. We want a movie to be exported and I'm going to select one setting from we and I prefer edge to 64 and I want a color film. So I'm selecting RGB in presets. It has vital part. It set impact for on edge to 64 is which is fine with me and in audio Kodak. If you don't have anything selected, then I would suggest that e select a c which is what I select on between 1 92 was fine with me on that will export audio also with the video file There's 11 setting we missed here is when you are actually animating which means you are exporting the video from blender What display you want to see when you say keep you I What it does is it reduces the amount off Oh, memory it requires to process the video. And so this is a good city. The next thing which I want to show you is this menu in playback you have to select audio scrubbing, a V sent and frame dropping. So when you scrapped the timeline like this, it will play the audio with the video in this preview window. So those are a few of the good settings. Once we have done all these settings, we need to save this file as a police certify. So savers to start a fight. So that will. Then when you click that another window opens, whether it's OK to save it as, ah save startup I and then you click. OK, so now if I close the blender application Onda, we open it again. You can see that the start off by loads by itself on it choose our it sets the same settings again, which we had said before be closed the program. It's to 60 porridge to 64 on. We had said easy is all your Kodak and so on. One more setting, which I want to show you, is ah, about when you click on file and go to user preferences goto system on. Then you have the sequence or Clipper editor memory cash limit. So you This is their amount off memory and located two blender when it is rendering the video. So if you have, for example, my machine has KGB off grams, so I'm going to set it toe ah value, which is about half of that. If you have higher memory or even lower memory, you can set it. You can try various settings and see what hum, how blender performs, so to change the value. What I can do is either I can enter a value here like 1234 All I click my left knows buttonholed it and then dragon so that it gets changed. So I'm going to set it to something like off 4000 values, which is about about four GB on that and then click Saviours of settings. So whenever, now again, I want to say the same starting point so that whenever I re opened blender, it is. It will buy, deport. Take that as the memory cast limits, so that's what it doesn't know. So this is where we have completed and introduction toe the settings in the blender on how we can save ah start of trial so that we don't have to make the settings every time we open blender based on whatever we have seen, the long you are now familiar with the blender to some extent, but it it's a very complex application and has more people settings on. Each setting has the potential to make the output better, and so you should try different variations off these settings, and then you will arrive at a start up fine. That's perfect for your use. So don't settle for the settings, which I am showing you going. Try different settings, for example, for including you can try for the farmer. You can try it to 60 40 to have that, then you can try impact for and then correct as to 64 so one and see more different results . It gives and then decide which one which format or which, according is the best for you news. The settings, which I showed you were the settings which I use personally, but by no means they're the perfect ones. But I hope this video has given you some idea of how to use a blender, which is a pretty cool for editing your videos. Thank you 3. Separating Audio File Using Blender: now in this lecture, let's see how to separate out the audio from the video file. So this there is a sample pile which have made just toe demonstrate various things in this class. So what I'm going to do is drag this file in tow the blender like this on as you can see, wherever it has come Exactly where the cursor are. The green line Waas. If I want to bring it to start frame, then what I can do is scroll hit home so that I can see the whole whole started end. This is the start line and is the end line. So what I want to do is are bring dragged these both the files here I'm going to right, click on first and then hold the shift button and right like the second month. And then click the G key so that I can grab them on, then drag them towards left. The zero value are zero cream if I want to. Now, as you can see, I cannot exactly bring them to zero. So if I want to zoom in this area than what I can do is press shift and be so that I get of course it like this. Then I can select an area and then Exum's into that. So again, I right click on this file shift and right click on this file again on the second file other and then hit G so that I can grab both of them and then bring them Go zero again. When I want to go back, I just hit the home button. Now I want to explore the whole off audiophile audio as a separate file. And this green bar is the audio part that fight And this is the video. How do you know that is when you click right click on the green bar. What even see is the type here indicated is the sound And when you click on right click on the other line you see the type as the movie. So I want to export this file as and audio fight. As you can see, you can see the preview off the video here on I want to click, view and fit Review in window. So this is the preview off the video, which I'm tryingto addict now. So now if I want oh, explored the whole audio. I cannot have any free mass to 50 which is this. I want to have a till here. So what I'm going to do is left click on the in cream and then drag it towards right so that I can take it to where I want on extent to the area where I want. So again, I'm zooming in by clicking Shift be on and the box getting the box. And then again, I'm going toe adjusted so that again I'm going toe left, click on the end frame and then drag so that it's just before the end off the audio. Now, how do you check if the audio there is no audio after this line is right? Click on this and scroll down here and then say, Draw a form. So as you can see the audio, it has drawn the way form, and it's almost ending here, So it's good enough for me to have an exported build it. So now when I want to export, I goto audio tab, and then I select the folder where I want Oh, save that file. So it's in online course on video making for and then here. I want to say sample, Are you exported from Lender? And I wanted to be MP three fights. I'm just typing. Got MP three and then I'm selecting MP three as the container and as 30 do as the format and now I'm going to hit mix down so that and writes that final as an MP three fight and shows that it's working its exporting that audio file on it's ready. So now when I go here, but the older I can see this exported MP three on, I can play that separately on now this can be here. I'm just trying written in the video. Audacity that I'll be using for in the next lecture will actually see how we can edit the file in order City on remove the unnecessary background noise and so that we can improve the quality off the audio 4. Editing Audio In Audacity: Now let's look at how we can edit the audio file to remove the unnecessary noise from the so called that we only use a tool called audacity on You can download it from or that city team dot org on install it on your machine. Andi, I'm going toe open audacity, and then I want to bring that MP three file into my or dusty program. So this is the audio file which I exported. I'm going to bring it here, and I see the way form a few things about recording audio is that before you record or start actually talking, you should have some time when there is no you're not speaking or you're not actually recording anything, which is off the importance. This is just to record the noise, which is there in the background so that you can select this and then use it to remove the noise from the rest of the fight. So if you see if I play this, it's going to play some noise. You won't be able to hear it because it's not too much. But then I want to remove this kind of noise from the whole fights. What I'm gonna do is select this and then we'll do effect noise reduction and say, Get nice profile. Now I want to select the whole file by pressing control a and then again, effect noise reduction. I'm not going to change anything. You There's the step to off. Nice introduction. I'm going to let this be as it is on then click. OK, so it's going to remove the noise from all of this. So now if I play this part again, you will. Even he may not hear anything because it's the noise is almost gone. If you still three lead, that is some noise in the background. You guns, select the area again and then do the same procedure again. So if you're now, you can. I'll play this audio again so that it will be much more clearer than it was earlier here. I'm just trying toe create a video that I will be using for as a source for a living on DSO . I'm just going toe the upset. So that's that's the cleaned up audio. If you feel that the audio levels are too low than what you can do, is can against you like the whole file by doing control e effect and amplify. And then you can select the what amplification level you want toe raise it toe and Ancic flick. Okay, toe increase the amplification, for example. And I'm going to let this be the default value. I'm not going to change that and then click. OK, but I don't want to do that right now, so I'm just going toe Say control Z which will bring it back to the level it was. And now I want to export this audio so I can save this whole thing as a project so that if I want to make some changes later on, I can. Same. This has a project. But right now, just for the sake off getting this file out, I'm just going to click export audio, and then I'm going toe right. No, don't go to that folder where I'm putting all my files. Andi here is that original by and now I'm going to write just for the sake of glad today I'm going to write. Are you edited? And dot mp three and Steve it on. Do you care? You can write. What is the artist name? and so many other things. But I'm just going to click OK on. It's going to export that fight. And when I go back to the folder, I have this file, which is a deterrent audio. I'm going to play that now. Here. I'm just trying toe create a video clarity which it has a tune may not be very clear to you because the original Kyle didn't have a lot of noise. But if you have a lot of noise in your audio recordings, this is what you will have to do on. Since our audacity cannot open video points directly, you have to separate out the audio from there and then bring it into audacity. Edited on again, Murdered in Blender We're going to do that in the next step. 5. Editing In Blender: No. We are at the stage when we have the original video. The audio exported from this video using the blender and the audio after editing it through audacity. And now what we want to do is merge this audio with this video on for that again, we're going to use the blender. So here the blender with all the settings which we did in the last lecture. So now I want to bring in the video and the audio files. And the easiest way to do that is toe grab this video. Andi, drop it in here. As you can see, it dropped the videos just at the place where the green cancerous. So if I wanted to start from zero, what I'll do is I'll bring the cursor here first and then bring in and drop the video file here. I can show that to you right now. I'm hitting controlled for undoing the action. I'm going to bring the Carson here at zero. You can see that it's at zero. And now I'm going to bring the video and Robert in here. As you can see, it has landed at the zero location on If you watch carefully. There are two parts off this video files which are being shown. The green one is the audio on Boil it one or the dark blue one is the one which is the video. How do you know that? It's when you right click on this file or this abortion off the file on you go up here in the properties you will see the type is movie on If you right click on this file part of the file even see that the divers sound So the convention which blender uses is the green One is the sound on the blue while it is the video part of it. So now I want to bring in the audio which is edited I'm going to snap it again here at zero on If you go toe till the end even see that there is a mismatch here you're gonna go, which means that the audio is not sink. So how do you think audio with the original audio or the editor on your with the origin and audio? It is way to do that is right. Click on this on go down and say what it does. Is it draws the way form. We chose the audio output, and I'm going to do the same for this again. And now you can. Now I want to zoom into this area, which so that I can align one of this audio part with this so that it sounds but or it thinks perfectly with the video. So to zoom in more than what I can do here is press the button shift and be so it gives me this kind off across here. Then I can mark the A d average. I want to zoom in and then release the most, and it brings me to a zoomed in view. Now I'm going to select this. Find out the selecting the file books in the same way as in blender. To select the file, you write like the fight on. If you want to move it, you have to. But it's the G button, which means it grabs the fight for the part of the fight. So I'm going to hear G, and then I can move. The files are the audio to sync it with the original audio. This is the audited editing audio, and this is the original audio. So now I play. If I play this part of the pile, you can see what is happening is if I want to zoom out again, I'm going to show you that in a moment if I want to zoom out again, I'm going to hit homes and then I can see the whole video. Now one more thing before we go in and check the audio sinking again. If you'll notice the start, start cream is at zero and infamy that which is this line The increments. You can see that it's 2 50 to 46 fight if I zoom in and select. Bring my girls are green cursor to that position. It is 2 50 to 51 which is just one ahead of that. So what I want to do is bring in the end frame still in the end of this video, because I want the whole video to be exported. If you want only a portion of that, you can reduce the end frame to wherever you want and export and blender will export only that part of the videos. But I want to go. I want to explore the holding so I'm going toe. I'm not going toe type in the value because I don't know the value. What I'm going to do is click left. Click on this left click on this end frame, hold the button down and drag it towards light so that it you will notice that this end cream is shown by the right. A dark line is being forwarded on. It's coming towards the end of this video. So now I've placed it here. Really, I will place it here now when I want to play this part again to see if it has think properly with this. How do you know what I'm going to do is played this part? Let's see here. I'm just trying toe create a video. You can see that it's linked up that it is not. I'm going to show you how it sounds when it is not sync up. So I'm going to again click this. I didn't audio G so that I can move it and the next minute again play the audio. See that for starting this war, I'm going to again hit controls it so that bring comes back to the position it waas and Now I'm gonna do mute this audio because I don't want that. It was just used for thinking of the position off the audio. And I again see that that is a lot of speed or time before anything starts here in the just and then sometimes becomes an annoying for the viewer something nothing is happening for some 23 seconds, which is not good. So what I'm going to do is cut this part off this part off from all the fights. So the way to do that is again, right? Click to select one part of the fight on this audio, I'm going to hit our hold down shift key against you like this and again hold the ship key down and click the video. Also. Now I can cut it by clicking shift gate. You can also see that many in the middle which is here for the street menu. You can cut at the frame. It is hard shift key. There is also a soft cut, but I don't use that very much. So I'm going to use cut hard at frame because I don't want these portions off the file. So I'm once they're cut. I can believe them easily. Once I select and hit in the delete button. Children, this man, you and I clicked Erase trips. Now they're gone. So now I want to bring these 32 against your location. So the way to do that is again, right? Click shipped Brentley shift frantic. And I can grab all of them by hitting G. Burton and bringing them to you can see the number here and the start of the file, and I'm going to bring them to zero. Now they are at zero. Verify it. Shift B and zoom in and see that that is evil. Okay, Now let's zoom out toe by clicking home button so we can see the whole thing. You can even delete this file on religious audio, but I let it be there just for the sake, off referencing. If I needed any time you can save this holding at the project, you can see it save or cve, as if I am will be here. And I'm going to save it in a folder where I save all my courses and I'm going to say give a name to the pile which is and they didn't video project. I even gave any name for the project. And the extension is dot blend and then see it as a blender fight so you can see that it has saved and the video project got planned is the file. You can use this or open this file to see the whole thing again. So now if everything is perfect, I can export it. And to export that I'm I need What I need to do is hit the animation. But But before that, if you have anything, are any portion off the video that you want to trim? Then again, you can do the same thing which I did hear at the start off the video you can support I want to print this part. Then I bring the cursor here on select all the three files and here chip gains Cut those files. And again, if I want to remove the porch until here, I can bring the concert here and again like these three files and hit shift gate. And I know I can delete these. I just don't want to delete them right now, but I just showed you how you can trim on a video. I'm going to hit control dead many times so that I'm back to the position it waas and now we are ready to. So this way you can bring in more audio. If you will have some music to be played in the background, you can bring in one more audio clip. If you have two or 32 or more videos, Toby Club together, you can bring them here. When one video ends, you can start another video. And then there are so many things which you can do with blender, like adding effects off, transform wife and so on. Blender is a very powerful tool, but I'm just showing you the settings which I use normally. Onda. They're the easiest way I found export an audio and video club together. One more thing before we export the files is that I can see that the end frame is much beyond the video exists, so I'm going to zoom in again in this area and bring in the end cream by clicking here the left mouse button holding it down and then dragging it towards left. And if you want to see, I can bring you can see that if I want. I need to dream even more off this video because this is that this screen is showing me the video, which the tool, which I used for according my video. But it's not a dream, that area. Let's leave it at that for for the moment. And then we can hit the animation button. But for just for the sake off this lecture of this class, what I'm going to do is I want to export the video very fast. If I do export the video for this whole length, it will take some, maybe half a minute a minute. I don't want toe extend this that far. So I'm going to use this end frame value, which is very small so that I can sure they exported file to you easily. So I'm just showing you what will be exported now. It will be exported from zero cream toe this free images 315 So let's play that idea first . Here I'm just trying toe create a video. Oh, here. I'm just trying. So that's that's what will be exported now. So let me go and hit the animation. But once you click that you can see. The progress is shown here on once. This goes 200% we can see the file which is being exported. Let's go to the pool. Don't know and you can see that this file is being created on is being exported. You can see the sizes. Zero gave me that. No, but if we go back, it's at 70% right now on. Let's wait till it completes. Now it's complete, and you can see that the file has sides off. 1439 Gaby and let's try toe played here. I'm just trying toe create a video. Oh, here. I'm just trying to That's the video which is exported. Thank you. 6. Video Compressing With Handbrake: Now let's look at how we can complicitous video, which we have using a tool guard Handbrake on. You can download that from and bring dot fr Onda. Uh, once you open it, it looks something like this. Now let's select the file which we want. Oh, accomplice on. And this is the file which we want to compress The container is before. If not, if it's something different for you, select and before click the Web optimized setting. Then we want to keep the aspect ratio and the Briton height seem I'm going to turn off anamorphic none, and I'm not going to crop anything, so I just want toe use the custom setting with But whatever I have, I have this 32 dropping from bottom because I used that setting when I recorded that video . So it's going to be the custom value of it is that if you haven't dropped anything while you recorded the video, then you should keep it zero. Then we make sure that all the critters are off the video. We will be using to 64 as the including correct on. We want to keep a constant frame rate and generally constant quality. I prefer to use a value which is about 23. In Henry. You can no different things about the setting by holding over the setting. So, for example, here, when I hold over the arrow, it tells me that the suggested values are 18 to 20 Onda uh, 22 23 for higher definition, 18 to 24 standard definition and 22 23 per higher condition. I prefer to use 23. If you happen to use average betrayed as the setting, then make sure that you used to pass, including so that the including is done much more optimally. Then let's go toe audio on Diz. The audio setting those correct which I use is is he so that subtitles I don't want o or I don't generally do it through handbrake chapters and add one chapters. You don't really have to do anything. The advance time is enabled only when you goto video on click this optimized video. Use at one stab instead setting, and then you can go here on you can change different settings. These are the default settings which are given by the hand brake for the advanced but again . You can hold over different values and see what they do. For example, that reference screams the same way. Loser 1 to 6. And I tend to use the more you and the better the compression. But the slower the in court. Once these settings are done, we can save these settings s so that every time we open hand brake, we don't have toe make all the settings all from scratch. So for that, what we can do is click on this ad button and then I mean, we can give name to our preset. Is that Let's see you just research Onda. We can save this and then we never be opened the handbrake. Now we can click on this and all these settings will be enabled by default. Final thing that you have to make sure that you give a correct destination where you want to save your compressed file is toe Give the part where you want to save the pile and the name of the fight The click browse It will take you Do you goto the brown folder with you wherever you want to save it and name the pile by deported has taken test hyphen one as the name of the file on which is okay for me. Andi. I'm no readyto. I'm now ready. Toe hit the start button. Now it's compressing. You can see the progress here, Onda. Once it is done, we can go to the files. So as you can see, it has compressed the pilot from 1439 gaby, 254 k b, which is a very good compression. And let's play The fighting was tryingto create a video Oh, here and that that the pile which has got compressed on That's how I achieved my video editing using the three programs. First, I used blender to split the video from the audio than a I did the audio in audacity. Then I bring it back again to blender on, merged the audio and the video and remove the older audio. And once that video file is created, I take it toe hand brake to compress it on. Make it the lighter in terms of size. And that's when my final video is ready. Thank you
