relabel toggle to 'LTX save audio' (default true) since audio always
generates on 2.x audio-capable models; the toggle gates mux only. hint
added to locale_en.json.
split add_audio_stream from write_audio. avformat_write_header runs on
first container.mux() and freezes the stream set, so audio added after
video packets has time_base=0/0 and raises 'Cannot rebase to zero time.'
atomic_save_video registers the audio stream before the encode loop.
Promote RIFE interpolation from a save-time kwarg to a real stage of the
processing pipeline so per-frame work (detailer, color correction,
postprocess scripts) operates on source-rate frames and the inflated
stream becomes the saved output.
- new modules/processing_video.py with apply_video_interpolation,
interpolation_factor, expand_infotexts; PIL/tensor/numpy dispatch
- video_interpolate, video_interpolate_scale, video_interpolated fields
on StableDiffusionProcessingVideo
- process_images_inner runs the helper after the batch loop and inflates
infotexts in lockstep
- save_video in modules/video.py and modules/video_models/video_save.py
short-circuit re-interpolation when p.video_interpolated is set; the
user-facing kwarg still flows into metadata
video_save passes [-1,1]-range pixels to rife.interpolate_nchw, but
RIFE v4.25's IFNet explicitly clamps inputs to [0,1] (Head and IFNet
forward pass), turning every negative pixel value into zero. v3.9
silently extrapolated and produced soft artifacts; v4.25 produces
washout. Convert to [0,1] before the RIFE call and back to [-1,1] for
downstream save.
