LTX Express by MGHerder

About Version 1.1:

There were a few fairly conspicuous spaghetti strings and a large cluster of get set nodes all arrayed in one place. They were taking up a lot of space! I set them there where I could see them when I was testing things -- specifically, the very stubborn Resize-a-Tron logic (earlier non-linear version). And later I realized that leaving all those nodes collapsed in two columns there was defeating their purpose -- they should have been tucked behind their respective variable input nodes. That's pretty much it, but I did have to add more get set nodes and in the process, I took a second look at a few things, tweaked the layout but I'm fairly happy with it so don't expect much to change from 1.0.

About Version 1.0.1:

This is my LTX workflow, which I have been testing and working with for weeks. It uses LTX 2.3. "Express" is my quickstart animation brand, I also have a Wan Express workflow, so check it out (link below).

The bones of this workflow came directly from RuneXX's well-known LTX Basic workflow on Huggingface. The basic workflow is easy to get started with, but has some cool features that do add to the onboarding: A KSampler preview, which requires a tiny vae, and so forth. You will need to download several models if this is your first time using LTX, and put them in the right folders.

My workflow includes several additional features. The inputs and video settings have been rearranged, with sliders. RIFE Interpolation can be switched between 48 and 72 fps modes. My Resize-a-Tron has been added to this workflow in the "LTX Edition" -- it's already been published by @LFPerfect and the only change is that when scaling, it automatically does so in increments of 64 pixels. The LTX edition handles swapping out the form factor, so it's a breeze to get a new image into your workflow and generate with it.

You don't need to know anything really about this subgraph as long as you understand that Scale Resolution takes precedence over Crop and Resize. And if you turn on Text2Image, then it only uses your 2d slider's resolution for the target latent size. Totally works, trust me. The linear structure was key.

What Size is it Going to Be?

Since scaling requires a calculation that can be a pain to do in your head, an image resolution node is included to let you check the resolution that will result from your chosen settings, without generating. Just select the node (purple) and press the blue play button. This only shows the size before the final upscale, but this is the number that is critical during generation.

Video Generating Options

The remaining options for generating offer a basic set of features that will allow you to begin generating immediately.

These are the recommended settings. Feel free to add any Loras to your choosing, and follow your checkpoint's guidance for strength settings.

The Seed

By default, this workflow has a fixed seed of 42. Change it, set it to Randomize, do what you want. I don't know how to get the node to be that color. Ask RuneXX. Probably manually edited the json for all I know. Leave a comment if you're so smart and know.

Special thanks to @LFPerfect for some tips on my workflow as we have been sharing notes. You may want to check out his Studio workflow based on LTX Express, link below. He's new here but his work is solid, give him a follow.

Also a special thanks to @lonecatone23 for help with workflow logic. When I got stuck, he had answers, and it's thanks to that help that I was able to build logic into this workflow such as the Resize-a-tron and the FPS selector.
