Drop I-frames, duplicate P-frames,
build glitch sequences. Free & open source.
Premiere-style timeline with zoom, scrub, and per-clip control. Drag to reorder, visualize frame density.
See glitches in real time. Parameter changes trigger a debounced re-mosh with instant frame display.
Operates directly on RIFF/AVI binary structure. No decoding, no re-encoding. Pure chunk-level manipulation.
Import MP4, MOV, MKV, WebM. Automatic normalization to Xvid AVI via ffmpeg before processing.
Fine-tune keep_first, duplicate_count, duplicate_gap, keyframe dropping independently per clip.
Insert custom I-frames between clips to control where motion vectors propagate. Seed corruption precisely.
Drop any video file. It's normalized to Xvid AVI automatically.
Set parameters per clip: frames to keep, P-frames to duplicate, gap, keyframe dropping.
Watch the glitch evolve in real time. Binary rewrite + frame extraction in milliseconds.
Export your moshed sequence as AVI. Multiple clips with different settings in one output.
