Frequently Asked Questions
Does changing video speed reduce video quality?
No! The video retains its original canvas resolution and renders at a high bitrate (6 Mbps) so your final video remains crisp and clear.
What happens to the video audio when sped up?
By default, our pitch preservation engine keeps voices sounding natural without the high-pitched "chipmunk" distortion. You can also uncheck pitch preservation or mute the audio track.
Are there file size limits or watermarks?
None! The tool is completely free, does not add any watermarks to your exported videos, and runs entirely on your device.
