Frequently Asked Questions

Can I convert 60fps to 30fps?

Yes — frame rate downconversion is fast and lossless. FFmpeg drops every other frame cleanly. Use this for compatibility with platforms that don't accept 60fps uploads, or to shrink file size.

What's the difference between upscaling and downscaling fps?

Upscaling (low to high, e.g. 30→60) requires generating new frames — that's where AI interpolation matters. Downscaling (high to low, e.g. 60→30) drops frames — fast and clean either way. The tool picks the right engine automatically.

Will frame rate conversion change my video's playback length?

No — duration stays the same. We're changing how many frames per second, not how many seconds total. To change duration (slow motion or fast motion), use the change-video-speed tool instead.

What's the best target FPS for YouTube?

YouTube accepts up to 60fps for smooth playback (and now 4K-120fps on some videos). For most uploads, 30fps is fine; 60fps if you want smooth gaming/sports footage. 120+ is mostly useful as a slow-motion source rather than direct upload.
