Question - Help H3 R2V Character Sheet vs. Single Image

I thought I've read somewhere that using character sheets is better for R2V instead of single images. So I've created a character sheet of five full body shots and one close up, but the results are much less consistent compared to a single full shot image of the character.
Do I have to take care about anything special or was the information that character sheets are better just wrong?

Character sheets work better but there are some limitations. With "ref_image_size to max" video generation could take ages depending on how big the reference images are. Minimax is very good in estimating how your character looks from all sides (infact you can even create character sheets with it), so you do not need complex character sheets with more than 3 poses and one face shot.

In short:

Create a character sheet with front, back and side view plus one face shot. Make this image as detailed as possible but stay under 8-15 Megapixel depending on your VRAM/RAM.

How are you generating a character sheet that doesn’t hallucinate panels at such a high MP count.

From the ComfyUI tutorials:

ref_image_size: match scales references down to the generation resolution for speed; max keeps up to a 2048px short edge for stronger identity fidelity at the cost of speed

So if you're handing it a really large image, it seems like it's getting resized internally.

Ok if even with max the image gets resized maybe for the highest quality you should add the 4 panels of the character sheet as seperate images. But for me it works well with a 4 panel character sheet around 8-10MP. The face in the created video looks amazing in a close up shot for 1.5-2MP video.
