LTX-2.3, simple workflow. T2V, I2V, I2V external audio, FFLF

Pretty simple workflow for LTXV with 3 modes so far and quite an early version. There is no prompt enchancer; in my opinion, it's useless garbage as a tool, and text LLM work mostly works very slow in ComfyUI. There is no latent upscaling. Almost the same useless garbage.

Setting the full resolution will be faster and better than half resolution and latent upscaling with an interpolated result, but it requires resources like second generation. If your system is not powerful enough for the full resolution you set, almost certainly the server will run out of memory on the latent upscale stage. And that's even worse in IMG2video cases with the pixel upscaler itself.

The workflow works fine on my 8GB VRAM videocard at 720p; I haven't tried higher resolution yet on FP8 dev model with distilled lora. There is a reason why VAE are separated into loaders and files, I haven't finished that part fully. Controlling it is the same as any other my workflow. If you try even one of my workflows, it will be similar.
