This looks amazing!
To keep things clean would you suggest a standalone Comfy for LTX?
Thanks mate, your work is as ever, really appreciated.
first time to comment ever, is for you man, this is Awesome, i hope you can also make the Motion Control Version Also
I'm having a problem with the comment nodes on your YouTube video; I'm getting the same error.
I just updated ComfyUI to 0.17... do you think I should be able to run your workflow?
hello thank you, this workflow is great.
v1.2 I keep getting an error at the "Load audio" node, regardless of whether the audio switch is set to true or false. Debug: Custom validation failed for node, audio - Invalid audio file: 15004c1a-7406-38dd-620d-5354060330c6.wav
Another Workflow that does not work.
Switches dont work.
T2V - True
First/Last Frame - False
Custom Audio - False
Still asks me to add each section marked as false.
Cant bypass them, another error then comes up.
The switches work for me. The issue that was throwing me off is the image and audio nodes have to be linked to something even if they are not used. If the switch says false the node appears active but the image or audio in the switched off node is not referenced.
you have to fill all the image nodes, audio nodes first even if you won't use them
rtx nodes not installing and a big fat X
I installed Llama-CPP-Python_Windows in the description and it worked for me.
try going into your custom_nodes>ComfyUI-RT-LTX2-RareTools
find Llama-CPP-Python_Windows(No_Deps).bat and double click. It will install automaticly. Restart comfyui.
Works great thank you!!
I wish generation would be faster tho. 12gb vram with 32 gb ram. Using 2.3 22b distilled 4QKM gguf.
5 sec upscaled final>1920p video took close to 8mins.
I would love to have faster generation (2-3mins with lower quality) then upscale the good ones with some other fast workflow too. If anyone have suggestion I would appriciate that.
or I can bypass second pass generation to make it fast but eventually do I have to rerun whole process with same seed to get upscaled video?
what setting ration did you used it?
Low Vram : 640 x 360 -> Final Video after Upscale : 1280 x 720 (720p HD)
Mid Vram : 960 x 544 -> Final Video after Upscale : 1920 x 1088 (Full HD)
High Vram : 1280 x 704 -> Final Video after Upscale : 2560 x 1408 (2K)
V. High Vram : 1920 x 1024 -> Final Video after Upscale : 3840 x 2048 (4K)
@nozilanozila 960x544 with final 1920x1080.
