- Why convert to 120fps instead of 60fps?
- Two reasons. First, 120fps matches modern 120Hz/144Hz displays — motion looks visibly smoother than 60fps on gaming monitors and iPhone 15+ / Android high-refresh screens. Second, if you drop 120fps back to 30fps playback speed, you get butter-smooth 4× slow motion — not the stuttering you'd get from naively slowing a 30fps source.
- Is 120fps overkill for most content?
- For viewing on a standard 60Hz display, yes — you'd see the same smoothness at 60fps. But 120fps shines for (a) slow motion (4× ratio from 30fps), (b) high-refresh displays (120Hz+), and (c) very fast action where 60fps still stutters. Budget 2-credit jobs suit short viral clips; 5+ credits for longer videos.
- How long does 120fps conversion take?
- On our GPU server with state-of-the-art AI, roughly 2-3× real time — a 30-second clip takes ~60-90 seconds. Browser mode is faster but uses FFmpeg minterpolate which doesn't generate true AI frames.
- Can I convert 24fps film to 120fps?
- Yes. That's a 5× frame multiplication — our AI handles it, though extreme ratios work best on clean footage without heavy motion blur. For film content you'll often prefer 60fps to preserve the cinematic feel.
