v1.2 - Fixed connections related to the "LTXVCropGuides" node. Due to a lack of understanding of the "LTXVCropGuides" node, the connection method in v1.1 was incorrect. This error may have caused artifacts after upscaling under certain conditions, so this version has been updated, but it is not guaranteed to fix the problem.

Also, some configurations have been revised.

I noticed this issue when I tried to introduce a certain node into a new workflow, and severe artifacts occurred in my environment as well. Because the node connection method is different, it is not guaranteed that this workflow will be fixed, but I am releasing it for now.

v1.1 - Fixed an issue where the target FPS was being applied even when RIFE was not being used. Please enable only either "RIFE..." or "Don't Use..." on the FastGroupBypass node. Also, corrected an incorrect connection to the NAG node.

v1.0 - I've released the workflow I've been using for generation. However, please don't expect too much support from me.

Even when using the fp8 model, downloading all the necessary files will exceed 40GB. Because of this, you will likely encounter an Out of Memory error unless you have at least 64GB of system RAM. In fact, I hit OOM errors myself depending on the resolution and video length I tried.

The reason I've separated Lora into First Pass and Upscale Pass is because I thought it might be better not to apply Lora too strongly to Upscale Pass, but it might not make much difference. In most of my past videos, I lowered Lora's weight in Upscale Pass, but I can't say for sure if that was meaningful.
