Is this the same as changing speed?
No. Speed change makes the clip shorter or longer. Changing FPS keeps duration and rewrites the frame lattice.
Change a video’s frame rate
Retarget 23.976, 24, 25, 29.97, 30, 50, 59.94, or 60 FPS locally. Handy before an edit, a social export, or a PAL/NTSC handoff.
Frequently asked questions
Will 30 to 60 look smoother?
Not by inventing frames. 30→60 duplicates frames. For real in-betweens you need an optical-flow tool.
Can I go from 29.97 to 24?
Yes. That is a common cinematic retarget. Some frames will be dropped to fit 24.
Do you upload the file?
No. Conversion runs locally with Mediabunny.
What container comes out?
MP4, ready for editors and social platforms.
Should I check FPS first?
If the header already lies (common with NTSC in MKV), run the FPS checker so you know the source lattice.
