PlagueKind - Minimax H3 - LTX2.3 Workflow - Ease of use - Eros | Sulphur Compatible | FaceID

## Minimax H3

## V1.5 Notes

- Added the option for T2V.

- When using T2V, set scale mode of Target Dimension node to Dimensions (WxH) or you will get a square video.

- Added FSR RCAS sharpening, 0.3 strength is very natural.

- FFLF is unreliable at res above 640, don't know why, it's like this on default WF as well.

- Target Dimension node controls the generation size only, refs are passed elsewhere.

- Don't touch the other hidden resize nodes as they only control ref size and are set to max.

- Euler + Linear Quadratic seems to be the best combo with between 15-20 steps.

- I didn't add easy cache because it ruins the quality noticeably,

- If you have time or a powerful card, try heunpp2 sampler. It's phenomenal.

## LTX 2.3

## V7 Notes

- Added FaceID tracking.

- Changed DMD Lora for smoother output.

- Steps required 4-10. 6 seems good enough.

- Pruna Video VAE for speed boost.

- Int8 Convrot TE.

- Any FPS choice seems to work.

- Increase IMG Preprocess for extra movement.

- ComfyUI broke subgraphs so I adapted.

- Make sure you're on atleast 10s-nodes 1.9.6

Thank you for your support.

## V6 Notes

- Updated Eros to 1.4 much better.

- You can disable all optional lora apart from distill and eros if you want. The others do enhance the output though.

- Added Volume Boost option.

- Using DMD for audio and video.

- Use 0.715, 0.2412, 0.0 2x FPS sigma if you see jitter

## V5 Notes

- Using decoupled distillation for video and audio, and smaller loras. - REQUIRED.

- Updated to Eros 1.3

- FPS bumped to 30fps default.

- 60fps native with 120fps via 2x now compatible.

- Added an actually useable NVFP4 model, even though int8 convrot is more or less the same size and speed.

- You can regain speed by disabling one of the optional loras, start with sulphur.

## V4 Notes

- New reference node injects reference directly into the model, mostly eliminating any drift.

- New DMD distill lora, fixes issues of original distill which broke decompression method and prompt adherence, no need to write a paragraph anymore. Preprocess returns for enhanced movement.

- Use 6-13 steps, default 8-9.

- INT8 Triton VAE for fast decode.

- INT8 Convrot added for increased speed on all cards.

- JoyAI lora another lora similar to omninft, this helps adherence, dialog, interaction and more.

- If using the nvfp4 transformer make sure to describe anatomy that isn't already visible in the image. I don't recommend using the nvfp4 text encoder for realism.

## V3 Notes

TURN DOWN NEW EROS LORA TO 0.7 I SET IT AT 0.9 and it doesn't look correct like that.

- Added Prompt Relay Node for advanced timeline prompting while keeping simplicity.

- Added VHS save video. AV1/WEBM CRF0 produces virtually lossless video with extremely small file size.

- Updated Eros Lora.

- Moved RTX VSR into sampler graph.

## V2 Notes

- Upscale and 2x fps have added tiled sampler to improve speed. if you don't like the output, experiment with cfg pp sampler, or add 0.715 to sigma. Current sigma are done on purpose to retain identity and quality of first pass.

## V1 Notes

- Focused Mainly on Speed and ease of usability while retaining single pass quality and likeness.

- First pass is more or less optimized.

- Identity Retention is pretty good.

- First pass balanced for speed and quality.

- Upscale and 2x fps work but will be optimized later.

- I would avoid using RTX VSR with the whole chain active unless you have like 96gb ram.

- Nvfp4 models are only for Blackwell, using them will not save you speed if you don't have Blackwell, but they should still work.

- Default settings of the first pass should produce good quality and sharp. I personally like to use this for a single pass and just render straight at 1280.

- Bumped FPS to 30 because it looks way bettwen imo, quality seems clearer overall and it gets rid of that ltx base fps look.

## Memory Chunk Note

- This saves vram and speeds up it/s especially on longer videos

- With 16gb of VRAM 3 chunks seems optimal for me

- If you get triton errors, enter the model loader subgraph and disable use triton kernels
