New features / Major changes

Now you can run 2 or 3 stage generation.

2 Stage: This is the standard one in the v1.0 and official LTXV workflow. This one takes your image size and divide it by 2 to create the video latent size, generate first pass at low res, then second pass for the x2 upscale.

3 Stage: This is the new one. Like the 2 stage, we take your image size and divide by 4 to create the video latent, generating first pass at very low res, then second pass to upscale toj x2, and 3 pass to upscale to x4 total. This take a bit more time but the final output is more dynamic (also audio) than 2 stages mode.

The 3 stage mode uses your original resized image. However, at these lower resolutions, certain sweet spots of the model are preferable and can be activated with the button shown in the image below. The latent size will be automatically resized to predefined dimensions based on your image's aspect ratio (landscape, portrait, square).

⚠ Important note:

On the 3-stage mode, it is important to keep the seeds of the uscpale passes identical and fixed, otherwise you will have texture smoothing and blur on the final render.

Control video slicer limit

To avoid generating an unnecessary extra second on short generation times, you can now choose the duration at which this extra second is generated and cut off. Value is in seconds. This system is there because depending on the loRA or parameters, I have weird hallucinations or burns on the last frames.

(In this example, it will generate an extra second if the duration is equal or more than 20 seconds. Under this duration, there is no more extra second).
