Frequently asked questions
Does changing the speed make voices sound chipmunk-like?
No. The audio is processed with a tempo filter that changes playback speed while preserving the original pitch, so voices stay natural at any speed. A 2x video sounds like fast but normal speech, and a 0.5x video sounds slowed without becoming deep or distorted.
What speed range is supported?
Anything from 0.25x to 4x, using the quick presets or a custom value like 1.35x. Slowing below 0.25x or speeding beyond 4x tends to produce choppy motion and unnatural audio, so the tool keeps you inside the range that still looks and sounds good.
Does this work on audio-only files like MP3?
No, this tool expects a video file with a picture track. For MP3, WAV, and other audio-only files, use the Audio Tools in the Video & Audio category instead - they handle audio conversion and processing without needing a video stream attached to the file.
