How to shorten a video? Make a Livestream shorter? Is this possible?
I am learning Blender still, so I don't know all the shortcuts and quickies on the software. With that said I don't know if this is even possible for Blender?
How could I make a Livestream footage shorter, compressed like? I want to make a SpeedPaint video for at least 15 minutes or less. I do not want to show an entire 2hr and 28 minute video. 

Thank you in advance !
Add a Speed control strip.



Then change the speed in the multiply speed control.



Then just adjust the render range of your project.
