Frequently asked questions
Will slow motion look smooth?
Frames are shown longer, not invented, so very slow speeds can look choppy. 0.5× usually looks fine.
Why does the sound not sound high-pitched?
The tempo changes while the pitch is kept, so voices still sound natural.
Is there a file size limit?
Files up to 100 MB. Longer or larger videos may take up to a few minutes to process.
