WYGWYL · the film in cels · compared
Found film against our footage, and seven ways to make the frames between drawings.
Every number here is measured on the film itself: 165 drawn patches for the first table, 9 patches run every way for the second. How each frame is made · the films.
1 · Found film and our footage, as cels
Found film draws better per keyframe than our own footage (colour error 4.43 against 5.62, value structure 0.907 against 0.884): at 640 px, mostly without colour noise, it simplifies into fewer shapes (45 against 60). It plays a little worse (pops 0.49/s against 0.21/s) and costs more (30.5 s of drawing per second against 25.6): old film cuts and flickers inside a patch, and every cut forces another drawing. Our own film keyframes (family "film", the fastest footage) are the hardest of all.

2 · The frames between drawings
The same keyframe drawings, made into in-betweens seven ways. Compute counts the in-betweens and the drawings (about 25 s of the full stack per drawing).

3 · What each way allows
| way | compute | output | editing | re-timing | quality and failure |
|---|---|---|---|---|---|
| A · blend (theirs) | 29 s of computer per second of film, almost all of it drawing a keyframe every second | raster frames | change a keyframe drawing, re-run the in-betweens | needs the footage’s flow | tracks well (track 0.78); boils where neighbouring drawings disagree, ghosts in fast motion |
| C · hold | 28 s per film s: no in-between work at all | each frame IS a drawing: the scene program’s vector SVG, editable and re-timable | any held drawing can be redrawn by hand or re-run alone | free: holds are the classic way to time a cartoon | does not move between drawings (track 0.07); pops at each new drawing (1.24/s) |
| F · EbSynth | 100 s per film s; the synthesis itself (CPU) costs more than the drawings | raster frames that keep the drawing’s own texture | change a keyframe drawing, re-synthesise | follows the footage’s structure frame by frame | tracks best and ghosts least (track 0.91, ghost 0.73); smears where new content appears |
| F3 · EbSynth, a drawing every 3 s | 79 s per film s, a third of the drawings | as F | fewer drawings to fix by hand | as F | keeps EbSynth’s quality with a third of the drawings (track 0.88) |
| G · RIFE | 29 s per film s; the in-betweens are GPU-fast | raster frames: learned morphs between drawings | change a drawing, re-run | free: it never looks at the footage | smooth between drawings but blind to the footage between them (track 0.21); best used to turn 12 drawings a second into 24 |
| B / D / E · carry, planes, morph | cheap (flow only) to moderate (vector rendering) | E alone gives vectors in every frame | E: move vertices by hand | D and E could re-time freely | lost on every patch in the first bench: carry tears figures, planes ghost them, morph mismatches shapes — all three need keyframe drawings that share their shapes first |
