When I use only the LTX upscaler with a video input, it takes the same amount of time or longer than when I use an image, convert it to a video, and upscale it with LTX.

It takes approximately 70 seconds on an RTX 5090.

ORIGINAL WORKFLOW (I2V): ltx 2.3 - i2v.json

UPSCALE WORKFLOW (V2V): ltx 2.3 - solo upscaler (idk porque demora como hacer todo el wf de ltx 2.3 desde 0).json
