"Is it possible to speed up a video using handbrake?"
In the above link, Mulvya show us how to speed up a video, but I want to know, if possible, how can I speed the video joining two or more videos and increasing the frame rate, for example:
I have 2 video files, which I need to join. Both are at 30fps and I want to speed up to 5 times and increase the frame rate to 60fps.
How can I do it?
