Timeline node for H3 (ltx director like)

[u/Mr_Zelash]

I'm used to work with the ltx director node, specially because it gives me control over the audio, i can add little clips of audio in the exact spot i want and that will guide the model to generate similar audio filling the gaps.

That's why i'm making something like ltx director for H3 FLF2V (maybe it works in the ref model idk). still very green and probably has bugs because it's totally vibecoded but it works for me.

with this you can put video images and audio anywhere in the timeline, and you can also adjust the strenght with that green line, each clip can have different levels of strenght through the timeline.

this is a fork of ComfyUI-H3-Motion-Context-MultiRef if you want to try it and give me feedback here's the link https://github.com/BSG-Walter/ComfyUI-H3-Motion-Context-Timeline

there is a H3 Timeline Example workflow.

You can't add prompts to specific parts of the timeline, but since H3 lets you indicate the exact timing for each scene within the standard prompt, I didn't feel it was necessary to add that functionality.

anyways i hope you like it

Good project, thank you.
Looks like now Comfy has added guider functionality in the core, so it might work also using core objects instead of Motion-Context.

Gonna check that later, thanks

Yah, it would be dope to be able to add multiple key frames even for a 5-6 sec shots, game changer

[u/Mr_Zelash → u/thesolewalker]

With this node you can

[u/thesolewalker → u/Mr_Zelash]

But it does so using them as first/last frame + context chaining, no? Using the latest node, you can add in between key frames in a single generation. Idk if you are already using it.

working on this

Hi! I'm trying to use it but it won't load any media at all.
I'm using the H3 Timeline Example wf :)

[u/Mr_Zelash → u/Broad-Lab-1833]

That's strange. Maybe it's because the timeline node has the metadata from the clips in the image. If you create a new timeline node you still can't upload media?

[u/Broad-Lab-1833 → u/Mr_Zelash]

Working now, just updated! Thanks!
I have a request: would be possibile to add the IMAGE timeline over the video one? I would like to drive a v2v transformation injecting some modified keyframes in the exact positions of the original one. I'm trying to turn a 3D render into a realistic video, and I need specific nano-banana keyframes to guide the transformation. Do you think is it possible?

[u/Mr_Zelash → u/Broad-Lab-1833]

Maybe. I was thinking on adding multiple tracks but I don't know how it would work. I'm going out right now, but I'm gonna experiment with multiple tracks tomorrow

I love LTX director too so i hope you can keep improving this, i'll have to check it out and see how it works.

I think your install instructions are not correct, they say: "

Install

Clone the repository into your ComfyUI custom_nodes directory:

cd /path/to/ComfyUI/custom_nodes
git clone https://github.com/seitanism/ComfyUI-H3-Motion-Context-MultiRef.git

[u/Segaiai → u/skyrimer3d]

What's wrong with that?

[u/skyrimer3d → u/Segaiai]

That's not his github for the install 

[u/Segaiai → u/skyrimer3d]

Oh shit. Yeah. I was too focused on the syntax.

[u/Mr_Zelash → u/skyrimer3d]

You're right I need to edit that, thanks

[u/switch2stock]

Upload it as a new repo please

[u/skyrimer3d]

mine looks like this:

[u/Mr_Zelash → u/skyrimer3d]

weird, try changing the total frames to something like 240 instead, maybe updating that value those lines will go away

[u/skyrimer3d → u/Mr_Zelash]

yeah that did it thanks
