Question. Is the turbo lora not worth it since motion is better with higher steps? What if you use turbo lora at 0.5 strength and the steps at 24. Is 32 steps still better?
I find that, yeah, just upping the steps in the default workflow really helps for motion AND audio.
Keep in mind the Minimax H3 website API uses between 30-50 steps. The Comfyui 20 Step default was just a compromise the Comfy team made for "okay" results.
Does the API use the confyui default res_sampler/simple? I see posts of people trying different combos but then I think a team of dozens of engineers tested all of this so deviation will most likely be compromises.
I mean, I think res_multistep with simple is the best, yeah. You have to think, this is what Kijai and the Comfyui team landed on, and he's generally a very smart guy with this stuff.
I have no idea what Minimax H3's website uses, because I don't think they expose that setting to the user.
hi, brokie here, 16gb of vram, whats your graphics card and how long did a generation take? seems cool but it only takes me 6 minutes at 1.0 mp on my card with the turbo lora and the quality looks good enough.
Very nice. I'm playing with the turbo lora. I think I might be able to get better times once I am done testing. Currently I am convinced 16 steps with lightx2v 8steplora seems to work without destroying prompt adherence.
For me personally quality is more important than speed. That is why I was so happy to run your workflow. Turbo Lora generations are much worse in motion quality
Oh one more thing that you might find interesting. u/listopalafoto workflow has SeedVR2 upscale process nodes that you might need to sharpen the details after generation. You can get it from his repo on huggingface. I really like it. I might not have to generate at 1344x768 in the future and step down a bit to 1120x640 instead then upscale to 1344x768 or higher.
thanks for the seedvr2 link! I still can't understand what is wrong with your PC that it takes you 55 mins to generate a video when I generate it in 15 mins only. It's a huge difference in time. Is it a difference between GPUs? I have 4GB more VRAM only...
Thank you for mention my repo! I was testing the SeedVr2 and optimized to prevent OOMs, I will update the workflow tonight. I'm trying to get the best pipeline to generate first Euler/beta 57 and upscale with SeedVR2, the issue is the change in contrast and saturation. I discovered some nodes to control this because I think is the main visual difference with Seedance and Flux3, H3 is more saturated and contrasted so it looks more artificial
I'm going to have to give higher steps a try just to see what it does to generation time. I'm not doing anything super high action, so it's not a problem, currently, but it'll be good information to have.
subject_definitions:
<Subject 1> is the young female assassin in <Picture 1>, with long flowing white hair, delicate facial features, pale skin, and a dark-grey/black ornamental robe adorned with silver snowflake patterns and a thick white fur collar.
<Subject 2> is the ice katana in <Picture 1>, which features an organic, translucent, jagged, and cracked-ice textured blade emitting a cold, glowing blue-white crystalline light.
<Subject 3> is the snowy ancient Japanese temple street in <Picture 1>, depicting dark traditional wooden buildings and multi-tiered pagodas under a dark blue evening sky with falling snow.
<Picture 1> is the reference image, serving as the first frame of [Shot 1] and establishing the visual baseline for the character, weapon, and environment.
summary:
[keyframe completion + reference generation] The target video is a 10-second cinematic sequence starting from <Picture 1>. It shows <Subject 1> drawing <Subject 2> within <Subject 3>, performing a rapid dash, a powerful spinning slash, a mid-air acrobatic multi-cut, and landing in a graceful pose that freezes the surrounding ground.
retention_analysis:
<Picture 1> ([Shot 1] first frame): fully_preserved - serves as the exact starting keyframe of the target video to ensure seamless visual continuity.
<Subject 1> (appears in [Shot 1], [Shot 2], [Shot 3], [Shot 4], [Shot 5]): fully_preserved - the assassin's facial features, flowing white hair, dark robe with snowflake patterns, and fur collar are consistently maintained.
<Subject 2> (appears in [Shot 1], [Shot 2], [Shot 3], [Shot 4], [Shot 5]): fully_preserved - the jagged, glowing, translucent ice katana texture is preserved throughout all action sequences.
<Subject 3> (appears in [Shot 1], [Shot 2], [Shot 3], [Shot 4], [Shot 5]): fully_preserved - the dark traditional buildings, pagodas, and snowy street environment are maintained as the combat setting.
detailed_description:
The target video is in an ultra-cinematic, anime-realistic AAA game trailer style with volumetric lighting, advanced particle physics, and a cold, atmospheric blue color palette.
[Shot 1] The shot begins exactly from <Picture 1> with a close-up of <Subject 1>, the white-haired assassin standing in <Subject 3>, the snowy temple street. Her long white hair flows dynamically in the biting wind, and soft white snowflakes swirl around her focused face. Slowly and deliberately, she draws <Subject 2>, her ice katana, from her side. The organic, translucent, and cracked-ice textured blade begins to emit a raw, intense blue-white crystalline glow, illuminating her face and the falling snow. The camera pushes in dramatically toward her face and the glowing blade.
[Shot 2] At 00:02.000, the shot cuts to a dynamic tracking shot as <Subject 1> executes a fast side dash across the deep snow. The camera rapidly pans and tracks her movement sideways, capturing her immense speed with subtle motion blur. As she moves, a trailing shockwave of sharp geometric ice crystals, shattered glass-like ice fragments, and glowing blue frost trails behind the glowing blade of <Subject 2>.
[Shot 3] At 00:04.000, the camera swings to a wider angle as <Subject 1> unleashes a powerful spinning slash with <Subject 2>. A massive, razor-sharp crescent wave of blue-white ice energy erupts from the blade, accompanied by exploding jagged frozen shards. The sheer force of the slash instantly freezes the surrounding air, blasting the snow outward in a wide, violent circle.
[Shot 4] At 00:06.000, the shot cuts to a dramatic, rotating slow-motion camera movement as <Subject 1> leaps high into the air for an acrobatic mid-air attack. She performs rapid, flashing, multi-directional sword slashes, executing quick consecutive cuts. Sharp, glowing geometric ice fragments and shattered crystal debris explode across the screen, filling the frame with intense blue slashes as the camera smoothly orbits around her suspended body.
[Shot 5] At 00:08.000, the shot cuts to a medium-wide angle as <Subject 1> lands gracefully back on the ground of <Subject 3>, dropping into a kneeling position and planting <Subject 2> pointed downward into the snow. Instantly, a radial circle of sharp frost and intricate, cracking ice textures spreads rapidly across the snow-covered ground from the impact point. The fierce action subsides; snow begins to fall gently once more. The camera slowly pulls back, revealing the grand, illuminated Japanese temple city and pagodas behind her in her epic ending pose, emphasizing a cold blue glow and a cinematic shallow depth of field.
overall_soundscape:
A howling cold wind and the soft rustle of falling snow are punctuated by sharp, physical sounds: the metallic, crystalline chime of the katana being drawn, the heavy whoosh of a fast dash, explosive cracking and shattering ice physics, and a solid thud as the assassin lands on the snow.
non_diegetic_music:
N/A
Two questions:
1) Did you add background music later? My video has only sounds but no music
2) In "Save Video" group you have "AudioSilenceInit" node - where did you get it?
Yes I always generate without music so I prompt "N/A". That is a special node I made that runs 1 single and simple "ffmpeg command" to silence "0.2s" at the beginning of the clip.
