What was wired in
I took a 960×544 clip generated with LTX 2.5 up to 1920×1088. Both frames show the same 960×544 crop, one from a plain lanczos upscale and one from Refine Details. The brickwork, the window bars and the faces have real texture in the refined version, where the plain upscale is smeared.
sharp photographic detail, crisp natural texture, fine surface detail, clean edges, natural film grain, high resolution footage
blurry, soft, plastic, smeared detail, oversharpened halos, warped faces
Notes
Refine Details is for footage that is clean but soft, such as LTX output. Deblur is for footage that is out of focus, and Decompression is for blocky, compressed footage.
The crops were cut after generation. The workflow produces the full 1920×1088 clip.
