NEW LTXV2.3 EasyFlow - v1.7

Create one-shot videos up to 30 seconds long !*

*(depending on your setup)

Files choice for I2V or T2I:

Archive file is the standard v1.7 for I2V users, using image as T2I latent size.

Config file is the custom v1.7 for T2I users who want custom T2I latent sizes.

This version includes :

Better and Easier UI
Prompt saver
Prompt Enhancer by LTXV2
Low Res - Debug and Process section
2 or 3 stage generation
Choose model type (Safetensor or GGUF)
Control video slicer limit
Save seed with prompt
3 stages preset resolutions
Control first and second/third pass distillation
Exposed Sigmas
Added RTX VSR for Upscale
Other minor adjustments

New features / Minor changes

Safetensor and GGUF models

Safetensor and GGUF models/Vaes/Clips are all in the same subgraph now, activation is still the same using the fast group bypasser.

Control distillation on passes

Now you can control the strenght of the Distilled LoRAs on first and second/third pass. Second and third passes are using the same strenght, I'll change this in the futur if needed.

Other Minor Changer

I added RTX Video Super Resolution for uspcale. I highly recommend to run with only one upscale method to avoid exploding your RAM usage.

Now Sigmas are exposed at the bottom of their generation group. Feel free to modify them as you need.

Same system, better visibility. Just choose when the slicer start to cut the last second of the video.

About LTXV Prompt Enhancer:

If you are an advanced user, I highly suggest you to replace this enhancer by another nodes using LM Studio and ask prompt enhancements to uncensored LLM models.

NEW LTXV2.3 EasyFlow - v1.5

(Preview samples are not post processed)

Create one-shot videos up to 30 seconds long !*

*(depending on your setup)

This version includes :

Better and Easier UI
Prompt saver
Prompt Enhancer by LTXV2
TensorRT Upscaler
Low Res - Debug and Process section
2 or 3 stage generation
Choose model type (Safetensor or GGUF)
Control video slicer limit
Save seed with prompt
3 stages preset resolutions

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).
