RIFE API Alternative: Migrate Your Frame Interpolation
RIFE is the open-source engine everyone starts with. Here is the honest migration map — and the two places a production engine behaves differently on purpose.
The migration map
| RIFE / FlowFrames | mlslabs API |
|---|---|
| --exp=2 (or multiplier) | multiplier: 2 or target_fps |
| --video=input.mp4 | input_url |
| Local train_log / model weights | Hosted model — nothing to download |
| inference_video.py | client.frame_interpolation.submit() |
| Multi-GPU queue script | Batch queue + webhooks |
Where we differ on purpose
Occlusion refinement: RIFE's biggest failure mode is warping around occluded areas during fast motion. Our engine refines occlusion with a dedicated stage — visible on sports and action scenes.
Per-content presets: RIFE is one model; we ship cinematic, high-motion and anime presets so the artistic trade-off is a parameter, not a fork.
Sample your content before committing
Frame interpolation is content-sensitive — always run a sample of your actual material through both before migrating. The API makes that a five-minute experiment.
