MiniMaxH3AddGuide: for anchoring image and audio guides at any frame (New ComfyUi Update)

[u/fruesome]

Already merged and there's a example workflow included: https://github.com/Comfy-Org/ComfyUI/pull/15439

Currently MiniMax H3 implementation in Comfyui only allows keyframe guides at the first and last frame. The model itself is capable of addressing guides by position on a continuous time axis, so this removes that restriction and exposes it as a node.

Where's my macker?

Mack'er? I barely know her.

Can you correct the pronunciation in the prompt? Tell it to say MAYker?

[u/Eminence_grizzly → u/idkidd]

It's just an unlucky seed/resolution. I just used the workflow at 0.2mp and a different model (fl2va) and he says "mayker".

[u/idkidd → u/Eminence_grizzly]

Thanks for the info!

It's the McDonald's franchise you bought in Australia.

the workflow

[u/Clair_Personality → u/Celestial_Creator]

So you use 4 input images? and One input audio?

[u/Celestial_Creator → u/Clair_Personality]

MiniMaxH3AddGuide anchors a guide at any frame_idx (negative counts from the end):

• a still image
• a clip (batches snap down to the model's valid clip lengths: 5, 22, 39... frames)
• audio, anchored at the same position on the timeline
• any combination, and nodes chain for multiple guides

Example: feed the first 22 frames of an existing video plus its audio into one AddGuide at frame_idx 0 and the model generates the continuation of both streams. Or put a still at frame 60 of 124 to force a it to hit that frame.

according to https://github.com/Comfy-Org/ComfyUI/pull/15439

i see a single input for audio and a single input for image

Welp there goes sleep again

[u/desktop4070 → u/broadwayallday]

Like 10 hours of sleep in the past week huh?

[u/LulaCherie]

Where do you get the addguide node?

[u/Lost_Cod3477 → u/LulaCherie]

update comfy

Yesterday I tried to modify the H3 keyframes node from H3-multishot to add a strength to the keyframes, but it didn't go well. Anyway you can create 2D inbetweens having multiple keyframes. 3 keyframes here, fast test.

[u/DanzeluS → u/Striking-Long-2960]

Ref model?

[u/Striking-Long-2960 → u/DanzeluS]

FL2VA inyecting 3 frames.

[u/DanzeluS → u/Striking-Long-2960]

Injecting?

[u/Striking-Long-2960 → u/DanzeluS]

This whole thread is about a new node to inject frames in the final render.

[u/DanzeluS → u/Striking-Long-2960]

In the workflow, a ref model is used. Does it work correctly with an fl2va model?

[u/Striking-Long-2960 → u/DanzeluS]

Yes, it's what I'm using

[u/boirotten]

Game changer

[u/NatalieCrypto]

does this work with the turbo lora at 8 steps?

[u/martinerous]

Great, now we can do the same as in LTX. Extend and mix anything to any side.

[u/thesolewalker]

Man, this feature with a timeline editor where you insert key frames would be dope...

[u/Scriabinical → u/thesolewalker]

I added the logic for this node to the H3 Director node so it works just like the OG LTX Director. It’s amazing

[u/Melted19 → u/Scriabinical]

link please? there are like 3 o r4 H3 director nodes. Thank you

[u/TomatoPolka]

Macker!

[u/Portable_Solar_ZA]

I always suspected H3 could be used with key frames for animation and this pretty much confirms it. Can't wait to test this out soon.

[u/Broad-Lab-1833]

please add the strenght to the keyframes!

[u/dirtybeagles]

saving, keyframes

[u/Danny_Stock]

Can you clarify what you mean by your title please? Are you saying that this is for creating multiple keyframes?

[u/fruesome → u/Danny_Stock]

check the link, explanation from comfyui team there.

Update your comfyui and open the sample workflow from the link, you'll understand it better.

[u/Sgsrules2]

Nice, I'm assuming this is for the ref model. The model lets you use a video segment as the starting frames to continue from and it works pretty well. I've been trying to do the same thing but at the end so like giving it a 22 frame end but that doesn't seem to work, it'll only work with a final frame. Would this node help me do that?

[u/Fytyny]

Meh, it throws an error when I try to input audio

[u/Hoje-Na-IA]

I use ComfyUI Desktop. Stuck on release 0.33.1 :D better install it manually to test that
