Frequently asked questions
Will converting 30 fps to 60 fps make it smoother?
Not really. Extra frames are repeats of existing ones, so motion looks the same. Real smoothness has to be recorded at a high frame rate.
Why lower the frame rate?
To match a project's frame rate, to make screen recordings smaller (15 fps is plenty for slides), or for a film-like 24 fps look.
Does this change the speed?
No. To speed up or slow down, use Change Video Speed.
Is my video uploaded?
No. FFmpeg converts it in your browser.
Does it reduce the file size?
Lowering the frame rate usually does, because fewer frames are encoded. Raising it may make the file slightly larger.
Can I use it on my phone?
Yes, in mobile Safari and Chrome.
