To increase the speed of your video by 10 times, you'll need a video editing tool capable of significant speed adjustments.

However, among our 12 recommendations, none allow for a 10x speed increase, with 8x being the highest limit available.

If you do happen to find an app that can accelerate your video by 10 times, here's how you can do it:
