With a 4070 TI SUPER 16 VRAM + 64 RAM what i should use, DEV or DISTILLED?
@zerocool22 You can use both of them! Dev is better quality, but slower
worfklow won't load.. I have the latest / greatest comfyui.
cant read properties of undefined , outputs
@trashkollector175 Did you update all the nodes in the workflow?
@RusselX the workflow will not load... I get an error immediately.
@trashkollector175 I've added a video example in archive, reload it please and try put into your comfy instead of json file. If it does not work, try to update all nodes in your comfyui, espescially LTX Video node
Completly ignore input image, what i am doing wrong? All nodes up to date, compression 36, image landscape, 121 frame, 24 fps, i2v not work for me.
@nafikovtt777 Hi! What number is in 🕹️ T2V mode / I2V mode window? It should be "2" for generation from image
@RusselX Of course 2, but the problem is not in the workflow for the most part, apparently I somehow can’t describe it correctly, because I can’t achieve a working i2v in any workflow, I will think and experiment further
@nafikovtt777 something wrong with ComfyUI probably, you should try to load clean ComfyUI to check it
@RusselX yes, i load clean comfy and update, and update all nodes, it's working now,
