Not a polished film pipeline. This is a working Lab experiment: prompt-driven local video generation, conservative render settings, and ffmpeg finishing until the clips behave like clean loops.

LTX-2.3 Fever Dreams on a 2080
Eight short local video loops made by pushing LTX-2.3 through a deliberately stupid escalation ladder: mandala, shrine, mineshaft, teeth cathedral, basement moth choir, organ clock, sludge court, worm university.
Better than it has any right to. The RTX 2080 SUPER only has 8GB of VRAM, so the workflow runs one render at a time in ComfyUI low-VRAM mode with 1GB reserved. The safe shape is 512×320, 97 raw frames at 12 fps, then a reverse concat to a 194-frame loop. The five new clips averaged about 7.1 minutes each, with spot checks showing roughly 2.6GB of VRAM used and GPU bursts in the 19% to 45% range. It works because the model is quantized and the job is disciplined.
Clarence writes a small env-var runner for each prompt, launches it as a transient user systemd unit, ComfyUI renders the raw segment, then ffmpeg folds the clip forward and backward into a seamless little monster.

01
Eyeball Flower Communion
A neon mandala flower keeps trying to become an eyeball, then a shrine, then a weather system with opinions. Pretty, wrong, and far too calm about what it is doing.
02
Clown-Organ Shrine
Purple shrine geometry, skull-ish petals, carnival organ pressure, and an electric flower core that looks like it learned worship from a corrupted VHS tape.
03
Salvia Mineshaft
A blue-green occult tunnel drops straight through the basement of reality. The walls are masks, the masks are caves, and the cave is probably looking back.
04
Wet Teeth Cathedral
A cathedral found behind a dentist mirror: pews made of enamel, stained-glass gums, chrome molars rotating like saints, and a flower altar that keeps learning how to bite.
05
Moth Choir Under the Floor
Pull up the carpet and the house is singing. Choir moths, damp hymnals, velvet larvae, pipe-organ roots, and a basement light that blinks back in perfect time.
06
The Organ Clock Parlor
A grandfather clock got tired of counting time and started growing instruments. Pendulums breathe, wallpaper sweats symbols, and every second is a small haunted accordion.
07
Angel Sludge Court
A heavenly courtroom flooded with fluorescent sludge. The angels have no faces, the witness stand is a jellyfish, and the verdict is just a color you can smell.
08
Worm University at the End of God
The final campus after reality gets tenure denied: worm professors, impossible chalkboards, halo mold, lecture halls inside a throat, and a mascot that is mostly a weather event.
