Qwen Team: absolute-time video alignment and windowed visual encoding

What changed

Extended dynamic visual processing to frame-rate variation, aligned temporal rotary indices to absolute time and integrated window attention in a native-resolution vision encoder.

Scientific scope

Extended dynamic visual processing to frame-rate variation, aligned temporal rotary indices to absolute time and integrated window attention in a native-resolution vision encoder. Dynamic resolution/M-RoPE already exist in Qwen2VL; acquired delta is absolute-time/FPS alignment and windowed encoder integration. Longer-video tests do not establish reliable recall or event localization on every video. Model sizes are bundled.
