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
How online frame interpolation works
Frame interpolation estimates motion between existing frames and creates new in-between frames. The result raises the frame rate without simply duplicating frames.
- 01
Upload the source clip
Use MP4, MOV, or WebM. ReframeFX reads duration, dimensions, codec, and source frame rate before rendering.
- 02
Choose the output cadence
Use 60fps for smoother playback, or 120/240fps when you need more frames for a slow-motion edit.
- 03
Review and download
See the xeconds charge before starting, follow render status, then review and download the interpolated result.
FAQ
Useful answers, without the filler.
What is frame interpolation online in ReframeFX?
Upload a low-FPS clip, choose a target FPS, and render smoother motion without installing desktop software.
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.
