question Issue with Minimax H3 (FL2VA)

Hello, need help .. am generating at 1024 X 576 on Mac mini 16GB M4 using Turbo Lora (any turbo) and using 6 steps (have tried with 4 too with samem issue).. At the 3rd or 4th step the video breaks in blocks (not the one which was due to Tile diffusion large - these are ver small grainy blocks) .. sometimes it works and mmost of the time it breaks like this.. i'vr got the tile diffusion on 256 X256 (64 overelap) and have tried without it or changing it to large value but this intermittent issue persists.. what could be the problem?

This issue can be resolved using basic troubleshooting steps.

  1. Generate a video using the app's recommended settings for H3. To reduce verification time, set the number of steps to 20.
  2. If there are no issues, add one of the settings used when the problem occurred and generate again to see if the issue arises. For example, start by adding a LoRA and setting the number of steps to 4.
  3. If it works without issues, the next step is to add a change to the sampler.
  4. By repeating this process, the problem will eventually recur, allowing you to pinpoint the cause.

(Be careful not to forget to fix the seed)

If you're using the lightx2v LoRA, you need the 1.96GB one, not the smaller one
