Freeze frames
Frozen or repeated frames where the picture stops for a moment are detected and rebuilt into smooth motion.
PRECISION REPAIR FOR GENERATIVE VIDEO
MotionFixer AI Video Repair
Fix freeze frames, skipped frames and choppy motion in AI-generated video. Automatic repair for camera hitches and trackable object stutter, with private uploads.
What it repairs
Fix freeze frames and skipped frames in AI video
AI video generators often output clips that freeze, repeat a frame or jump ahead. MotionFixer finds these errors automatically and repairs only those moments — the rest of your video stays exactly as it was.
Skipped frames
Dropped frames that make motion jump forward are found and the missing in-between moment is restored.
Stutter & judder
Uneven pacing and periodic repeats from frame-rate mismatches are evened out to a steady rhythm.
Camera hitches
Sudden camera stalls or jumps in AI shots are smoothed without touching the clean parts of the clip.
Post-production workflow
Targeted frame reconstruction in 5 steps
Never rebuild a full sequence because of one unstable transition. Process only the exact damaged frames.

Why does my video freeze or stutter?
Repeated frames can hold movement still; skipped frames can make it jump. If the fault appears at the same moment in multiple players, it may be in the source file rather than your internet connection. Check the original before changing it.

Long freezes, hidden or very small objects, changing faces, spinning blades, water and smoke may not be reconstructed reliably. Uncertain repairs can be rejected and original frames retained. No tool can guarantee a flawless result for every source.
