361 frames with sound, from a 300-word prompt naming ten sequenced gestures, made

on ZeroGPU in 198 s. The full prompt is in

Two things had to be fixed before a clip this long held together, and both were
|
| 136 |
+
in this project's own defaults rather than in the compression:
|
| 137 |
+
|
| 138 |
+
* **The sampling schedule did not adapt to length.** `DISTILLED_SIGMAS` is nine
|
| 139 |
+
fixed numbers; `LTXVScheduler` derives its shift from the latent's token count,
|
| 140 |
+
and a long clip carries several times more. Left fixed, the sample never
|
| 141 |
+
converges — furniture renders semi-transparent and saturation halves. Clips
|
| 142 |
+
past 15 s now switch automatically.
|
| 143 |
+
* **The vendor's second pass was being skipped**, on an unmeasured assumption
|
| 144 |
+
that a 16 GB card could not afford it. It can, at 10.03 GiB, and it is worth
|
| 145 |
+
4.1x the Laplacian variance.
|
| 146 |
+
|
| 147 |
+
Details, the measurements, and the failures behind both are in
|
| 148 |
+
[`samples/long/schedule.md`](https://huggingface.co/topabaem/LTX-2.5-Text-Encoder-4bit-8GB/resolve/main/samples/long/schedule.md).
