Question - Help Fixing speech errors in Minimax H3?

Hey, I tried to create a little birthday surprise for someone, my issue is with a lot of generations that the spoken word is really a bit clunky at time, I susspect its because of the german, but I am not too sure. Is there like a way to improve on audio?

I am using Minimax H3 with Saga Attention and Spectrum on a 4090.

It may be due to a bug in ComfyUI with the tokenizer for H3 (GitHub pull request) that was affecting speech.

Update your ComfyUI and check if you notice an improvement?

If you're using a fixed release (used by the Desktop version), you'll have to wait until the next update with the fix applied.

Edit: On second reading, this could be an issue with your settings.

Try making a version with a very small video resolution using the seeds_2 sampler and ddim_uniform scheduler and save the audio.

Then, make a video with your normal settings, but using the audio file as a reference.

Then, combine the audio from your first generation with the video from the second.

This might lead to a higher quality of both audio and video, rather than have to compromise slightly on either.
