- Why go from 60fps to 120fps?
- Two reasons. First, modern high-refresh-rate displays (120Hz / 144Hz / iPhone ProMotion) show 120fps motion as visibly smoother than 60fps — great for gaming clips, drone footage, and action camera videos. Second, if you drop a 120fps clip back to 60fps playback, you get clean 2× slow motion without the choppy frame-rate mismatch of slowing 60fps directly.
- Do I need a 120Hz display to benefit?
- For native 120fps smoothness, yes — a 60Hz display can't show more than 60 unique frames per second, so the extra frames go to waste at playback time. But the 120fps file is also useful as a source for slow-motion editing (drop to 60fps playback for 2× slow-mo, or to 30fps for 4×).
- Is 60fps → 120fps better quality than 30fps → 120fps?
- Generally yes — starting from 60fps means the AI only has to generate one new frame between each existing pair (2× ratio), instead of three (4× from 30fps). Lower ratios produce fewer artifacts and faster processing.
- How does this compare to true 120fps capture?
- AI-interpolated 120fps is very close to native capture for most content — smooth motion, no judder, no ghosting on typical scenes. Extreme fast motion (rapid camera pans, fast object movement in busy scenes) can occasionally show minor artifacts, but for gaming highlights, sports, and most action footage the difference is hard to notice.
