Frequently Asked Questions
- Is there a free online frame interpolator?
- Yes — this tool is free for short clips in browser mode (FFmpeg minterpolate). Longer clips and AI-quality processing use credits, but the first few processings are free for new visitors. No software install needed.
- How long can my video be?
- Browser mode works best for clips under 2 minutes due to memory limits. Server mode handles up to 10 minutes at 1080p or 5 minutes at 4K. Pro accounts lift the duration cap further.
- Will this work without downloading software?
- Yes — everything runs in your browser or on our GPU server. No Flowframes, no Topaz, no install. Browser mode in particular keeps your file local to your device.
