- Why is 24fps to 60fps a 'tricky' ratio?
- The ratio is 2.5×, meaning the AI sometimes needs to generate 2 new frames between existing frames, and sometimes 3. Older interpolation methods handle integer ratios (like 2× or 4×) more cleanly. AI interpolation handles fractional ratios fine because it models continuous motion — but it does best with Server mode rather than Browser mode for this conversion.
- Will my movie footage lose the cinematic look?
- Yes — that's the point. The 24fps shutter look (also called 'film judder' or 'cinematic motion') is part of why movies feel theatrical. Converting to 60fps removes that look, making motion feel smoother and more like sports or live TV. Some viewers love this; others miss the original feel. Try a short clip first.
- Is this good for anime?
- Yes — anime is typically produced at 24fps (often animated on twos, so effectively 12 fps of actual motion). Interpolating to 60fps dramatically smooths fight scenes, transformations, and camera pans. We have a dedicated /tools/anime-60fps page tuned for anime sources specifically.
- Does interpolation work on 23.976fps (NTSC)?
- Yes — our tool auto-detects the source frame rate from the file. 23.976fps (NTSC film standard) and 24fps both work the same way through the AI pipeline.
