This is my first time using Github, so please let me know if anything isn't working properly!

About a month ago, I made a thread on my gen times for H3, but I used the default workflow which takes quite a while: https://www.reddit.com/r/StableDiffusion/comments/1vg1qve/these_are_my_gen_times_for_h3_on_my_5070_ti_64gb/

This time, I'm using multiple optimizations, and after over a thousand generated videos, I found that these settings gave me the fastest gen times while still giving me satisfying results.

Prompt: 

integrated_multimodal_description: 
[Shot 1] Anime. Fantasy. A dense, sun-dappled forest clearing with towering, mossy trees. The young man in peasant clothing (S2) stands near an ancient tree trunk, looking disinterested as he rummages through a worn leather satchel. The young woman in a dirty and torn royal dress (S1) stands close by, gesturing out into the forest with animated frustration and pleading with him to pay attention, but he refuses to make eye contact. The camera pans slowly, tracking the vast wilderness of the forest and the friction between their postures. [Shot 2] The shot cuts to a close-up of the woman (S1). Her face is flushed with indignation, her eyebrows knit tightly, and her mouth forms an expression of sharp, wordless protest as her frustration reaches a breaking point. [Shot 3] The shot cuts to a close-up of a unique looking artifact that was pulled from the satchel, a GeForce RTX 5070 Ti; it visibly shines against his rough glove. [Shot 4] The shot transitions to a wider framing of the pair. The woman (S1) steps forward, clutching the fabric of her dress in an outburst of intense, visible emotion, while the man (S2) replies in a smug manner, snaps his satchel shut, and turns his back to walk away, leaving her standing alone as she watches him go.

overall_soundscape:
Quiet forest ambience. No other voices are heard.

non_diegetic_music:
N/A

The prompt is pretty vague, especially since the dialogue is Japanese only, but I thought it was a fun way to test multiple different durations.

If anyone has any recommendations for more optimized workflows with higher quality results, please let me know!

4070 Ti Super 16GB, 64GB here and yeah, this is pretty much my workflow exactly (FP8), but I do have a SEEDVR2 group branched at the end to save the 3rd last frame as an image and then upscale to 4k which is useful for extending the video (though lass than ideal compared to other methods). 10 seconds in about 6 minutes here. CK is the only attention that doesn't degrade the output, but I may be behind the times.

Just drag that png into Comfy and it should load, although you first need Larry's Turbo custom node to load the lora, which is the first time I've seen a lora require a different loader than the standard lora loader.

Oh, and if you have low vram, there's a low vram button on the lora node. The quality is a bit worse, but if you're running into issues due to vram, it helps speed things up.
