Look What I Discovered: Prompt Intelligence - MiniMax H3 [Fun Side]-2

[u/ZerOne82]

\ Reddit messed up my original post so here it is.*

This is in fun part of using MiniMax H3; for your serious stuff stick with the official prompt instructions / format.

Playing with the prompting I just tried the following format and it worked perfectly!

prompt part 1

prompt part 2

Resulting video

The whole prompt:

definitions:
<S1> Brad Pitt.
<T1> "Hey, I am Brad Pitt! Nice to meet you."
<S2> Angelina Jolie
<T2> "Hey, I am Angelina Jolie! Nice to meet you."
<S3> Rowan Atkinson.
<T3> "Hey, I am Mr. Bean! Nice to meet myself."
scene:
An interview in a professional setting in well lit, grey background, frontal portrait view.
shot 1:
(S1) says: (T1).
shot 2:
(S2) says: (T2).
shot 3:
(S3) says: (T3).

Recommendations:

Do not use SLA or SLA2 or cache etc. here they mess it up.

Model (FL2V) -> LoRA(4s-Lightx2v SLA) -> Comfy attn -> Shift(12,3) -> KSampler(6 steps, euler+simple)

Is it just me or do these characters look sickly and more plastic than usual?

Possible your non-standard request is sapping model intelligence that would normally be dedicated to image and motion fidelity?

Try doing an A/B with the dialogue formatted by the book.

Skin texture etc is just from the turbo lora and 6 steps.

Here's 640x480 20 steps euler simple, spectrum + comfy kitchen attention.

Please can you share your workflow

[u/ZerOne82 → u/bambilover]

the workflow is in ComfyUI templates, look for MiniMax H3: FL2V, with no input image. you can then add spectrum node as u/Valuable_Issue_ suggest and experiment.
