The crop's size is derived from the mask, so an EmptyLTXVLatentVideo built
upstream cannot know it -- and a latent that disagreed was not an error
anywhere. The model sampled at the latent's shape and the paste-back squeezed
the result into the box: a face crop is portrait, sampled into a landscape
latent it came back visibly deformed, and under crop_mode zoomed the deformation
changed frame to frame. The only cure was to run once, read the size off the
debug string, rebuild the latent and run again, after every change to the mask.
The sampler now rebuilds the latent's video stream at the crop's shape when they
disagree, keeps the audio stream as it is, and reports it in debug. Nothing is
lost: at denoise 1.0 the initial latent contributes nothing, and the inpainting
path overwrites the video stream with the encoded guide regardless.
BFS Crop Size stays useful for building the latent at the right size up front
(skipping the rebuild) and for taking the per-frame boxes straight to BFS Paste
Back, but it is no longer the price of a correct result.
