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 a video FPS converter should do
Changing the FPS header or duplicating frames does not create smoother motion. A motion-aware converter generates new frames and preserves the clip’s playback duration.
- 01
Read the source correctly
Probe duration and frame rate from the uploaded file rather than relying only on its filename or export preset.
- 02
Choose a useful target
Use 60fps for smooth playback, 120fps for standard slow motion, or 240fps for a deeper slow-down.
- 03
Keep pricing predictable
Estimate from verified duration and target FPS, then charge the same figure shown before the render starts.
FAQ
Useful answers, without the filler.
What is video fps converter in ReframeFX?
Choose a target FPS, preview the cost band, and render smoother motion from the browser.
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.
