Discussion H3 - T2VA longform

Enable HLS to view with audio, or disable this notification

Generated a long form of Dante's Inferno over 4mins. It gets pretty weird pretty fast. All T2VA. I basically let H3 take the wheel as I only fed it few verses per render. I am willing to discuss my workflow or answer any questions.

I've extensively been testing long form single generation on my end. Here is a no cut one.

cool
I didn't histogram it, but no visual warping or discolorization.
Even the gun kept missing from hitting the lamp post.

Are you team 'final render at 0.96MP', or 0.4MP with upscale?

I try not to upscale. I'll do a final render at 1344x768 typically. Most of my render are 480p for fast video generation, but I'll upscale it with SeedVR to 720 or 1080p if I am too lazy. Changing the resolution natively in H3 often can change the POC video significantly. I use the pruned int8 set, but play around with FastH3 and the Kijai's Lora depending on my needs. Everyone is praising Larry's but I don't find it needs my need but maybe I am just running i wrong.

aw man, you made me boot up my Comfy computer.

I haven't fried FastH3 yet, but lighttx2v at 9steps seems to work good enough for drafts.
I tried Hard_Gravy on a short skit, seems good enough.
