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.

ReframeFX fills the gap between captured frames.
Direct answer
What this workflow covers.
Upload MP4, MOV, or WebM and estimate charged xeconds before rendering.
Choose a target FPS such as 48fps, 60fps, 90fps, 120fps, or 240fps cinematic slo-mo based on the source clip.
Render in the cloud instead of tying up a local GPU or installing a desktop interpolation app.
How it works
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.
FAQ
Useful answers, without the filler.
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 charges whole input seconds at the target-FPS band: 1× up to 60fps, 2× for 61–120fps, and 4× for 121–240fps.
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.
