Increase video FPS without using your GPU.
Convert choppy 24, 25, or 30fps footage into smoother 60fps, 120fps, or 240fps cinematic slo-mo output from the cloud.
For users who know the problem as low FPS rather than frame interpolation.
What changes when you increase video FPS
A higher frame-rate file only looks smoother when it contains useful new motion samples. ReframeFX creates those in-between frames instead of repeating the originals.
- 01
Keep the source cadence
The source FPS is detected automatically, so a 24fps, 25fps, or 30fps clip starts from its actual cadence.
- 02
Select 60, 120, or 240fps
Choose 60fps for everyday smoothness or a higher target when the edit will slow the footage down.
- 03
Render without local setup
Processing runs in the cloud, leaving the local machine free for editing, review, or other work.
What is increase video fps online in ReframeFX?
Convert choppy 24, 25, or 30fps footage into smoother 60fps, 120fps, or 240fps cinematic slo-mo output from the cloud.
Does ReframeFX show the cost before rendering?
Yes. ReframeFX estimates charged seconds before a render using input duration, source FPS, target FPS, and interpolation factor.
Can I use ReframeFX without installing desktop software?
Yes. ReframeFX is a browser and API workflow for cloud frame interpolation.
Does changing FPS change the video duration?
No. Frame interpolation adds motion samples while preserving playback duration. Higher targets can also be interpreted at a lower timeline FPS for slow motion.
