Run your video through MediaInfo. Look for:

Between 1999 and 2004, many studios transitioned from cels to digital ink-and-paint. This led to persistent artifacts: stray vector points, unclosed paths, corrupted alpha channels, and “ghost frames” where a character’s limb would stop moving for 1–3 frames mid-action. In fan circles, this era is called Shinseki no Wana (New Century Trap). shinseki nokotowo tomari dakara animation fix

If you see “Shinseki Nokotowo,” it likely refers to the leftover data (残り物 / nokorimono) from that era – orphaned keyframes, broken interpolation curves, or retired animation layers that were never purged from a project file but still cause playback glitches. Run your video through MediaInfo

Command line example for one corrupted cut:

ffmpeg -i broken_ep.mkv -vf "select='between(n, 1245, 1248)', setpts=PTS-STARTPTS" tomari_cut.mkv
python tomari_fix.py --input tomari_cut.mkv --method flow --strength 0.85 --fix-orphaned-vectors
ffmpeg -i original.mkv -i fixed_tomari.mkv -filter_complex "[0:v][1:v]overlay=enable='between(t,3.2,3.5)'" final_fixed.mkv

Expected output: The 1–3 frozen frames will now have fluid motion. No more “Shinseki Nokotowo” stutter.
