Change video speed

Speeds a video up or slows it down. The audio is stretched with a tempo filter rather than resampled, so voices keep their pitch instead of sounding sped-up.

One video file

up to 400 MB

Video work happens on your own processor, so it is slower here than in a native app — expect roughly real time, and the engine downloads once per visit (about 31 MB). Nothing is uploaded, which is the trade.
