Thanks a lot for all that valuable knowledge you shared with us! It is actually quiet appreciated! I 've never done any kind of video editing before with any software, and now I was able to do and understand at least the basics, and with a node base video editor!! Thank you again!

Now, in this project I tried to cover/use everything you tough in these classes. These are the screenshots of the videos/footage used for this project:

Now the project file is here so you can go ahead change and play with it as you like. You will need to modify the READ nodes a little bit though.
