Workflow : Long Video with Custom Audio
I2V & T2V - Long Extended Video with Custom Audio
Create longer shot with extension groups that extended the video incrementally to a longer length.
In theory infinite length, but the model will forget what it rendered in past windows, so realistically for minute or two shots.
Its not a simple or clean workflow, so might not be for everyone ;-)
(and basically extending 2-3,4 or 5 videos in a row, is heavy on a computer, so might not work for all)
Limitations
High experimental, and results may vary. There is a slight degrading of quality over time as well as introduced changes, and that might come apparent in the subject's identity (unless you create a character lora).
The extensions also have no idea what happened in extended groups in in far past (lets say you are generating extended video in group 3, it has no idea what went on in group 1).
Its less ideal for anything where you go to one place, and return to same place later. More suitable if the subject is constantly moving to new places, like say a person walking through the city, or if the subject is staying in same place using the IC Static Camera Lora (for example a scene with dialog, singer or similar where the camera is not moving)
Probably mostly usable if you are generating multiple clips to combine in video editor, and need one or two longer shots ;-)
But if you are in the experimental corner, feel free to play around : https://huggingface.co/RuneXX/LTX-2.3-Workflows/
i'm really impresive with your work. A big Thanks bro!

Happy to hear ;-)
(the above workflow is a tiny bit experimental at the moment, so might come update to it, at least as far as cleaning it up a bit, less spaghetti.. ;.))
https://github.com/kijai/ComfyUI-NativeLooping_testing Kijai has worked on a new node to make this a bit simpler, it's released for testing, maybe interesting for you to update the workflow at some time. Thanks for your workflows.
Yes already noticed that node ;-) loop nodes can be quite useful and flexible.
Been meaning to clean up mine, it was a quick proof of concent.. But its a lot of spaghetti mess, so it will benefit from a clean up ;-)
will test that loop node too
how do I remove the custom audio from this? I want long videos without custom audio and bypassing it is not working, removing breaks everything

Updating the workflow to make it a bit simpler, and some other improvements.
Will add an audio bypass as well ;-)
I was trying to bypass the Prompt Enhancer and it seemed like a switch on that would be a very nice addition.

Should be, I usually add that, its at the horizontal "bar" below the main areas. But will check , and add if not
NEW
I2V & T2V Long Length Video - Single Pass loop extender
New much lighter and simpler workflow for long video generations with custom audio.
And some improvements and fixes, with some inspirations from Kijai.
For prompting, prompt something like "static camera. Focus on main subject" or something like that if you want a singer video.
(might come some loop improvements later on if added to Comfy)
Will update the 2-pass long video workflow asap ;-) Should work far better after the update
Text 2 Video variant. With no image input ( same workflow, just set the image strength to 0 in the settings bar at bottom of the workflow)
Rendered it in lower resolution than the I2V one, but just to show it works (with higher resolution, even better quality)
