Frequently Asked Questions
How much time do I save at 1.5x speed?
Watching at 1.5x speed saves you 33% of the time. For a 60-minute video, you save 20 minutes. Our tool calculates this automatically for your specific file.
Does the audio sound weird when sped up?
No. We use intelligent pitch-correction (atempo filter) so people don't sound like chipmunks when you speed up the video.
