Direct 640 × 400 center crops from 1920 × 1080 source frames; lossless WebP crop encoding, no spatial upscaling or temporal interpolation. Context clips are silent, resized, native-cadence re-encodes. All times are source presentation timestamps, not recovered editor keyframes. Displayed frame numbers are one-based within each window; JSON frame indices and source indices are zero-based.",
