Preview comparison

Prepare a clip to inspect source-frame timing and generated frames.

Frame duplication repeats existing frames · Blend crossfades between frames · Motion estimation shifts pixel blocks to follow movement. Abrupt scene cuts are protected automatically. Preview wipe is not included in video exports.

Changing FPS, clip range, or resolution requires preparing again. Changing the interpolation method uses the already-decoded source frames.

Original soundtrack

On supported browsers, source audio is captured locally. Slow motion also slows and lowers the audio pitch. PNG sequences never contain audio.

Lossless frame sequence for video editors · limited to 240 images / 80 MB. Guaranteed frame count, unlike WebM recording.

WebM exports are recorded in real time: frame cadence may vary under load. Choose soundtrack behavior above. Original audio is captured when the browser exposes a real audio track; no fake audio is generated. PNG sequences retain exact frame timing without sound. Keep this tab visible during recording.

Is this neural AI?

No. This version uses transparent, local interpolation algorithms—not RIFE, FILM or other neural models. Motion estimation is experimental and may distort fast action, occlusions and thin objects.

Free video frame interpolation and slow-motion processing

PixelOkay Video Frame Interpolator is a private browser-based workflow for turning short clips into smoother motion, creating slow-motion b-roll and previewing different interpolation methods. Unlike neural frame generation, this tool uses direct frame duplication, optical crossfading and block-based motion compensation with scene-cut detection. No source media is uploaded to PixelOkay servers.

For long movies, high-resolution production footage, advanced pitch-preserving retiming or neural frame generation, use a dedicated video editor or a separately validated model. Results depend on source motion, frame-rate estimates, and available browser resources.
