After days of experimentation, a user got LTX 2.5 distilled 22B quantized to Q4 running locally on an M1 MacBook Air with 8GB unified memory. Settings: Balanced mode, 448×256, 24fps, 6 sampling steps, framed to 1.85:1. Timings: a 20s clip took 16m42s, plus a 10s extension (9m30s) and a 6s extension (5m45s) — roughly 32 minutes of rendering for 36 seconds of footage. He credits Codex with helping optimize the pipeline and calls this resolution the sweet spot for his machine.
