When video is in an iframe, it dynamically adjusts bitrate, resolution, and frame rate based on network conditions. At initial connection: typically starts with lower bitrate for quick connection and network adaptation. As network conditions stabilize, image quality gradually improves. If poor quality persists, try exiting and re-entering picture-in-picture mode.
Some videos show subtitles but can't translate/translation is too slow
Different subtitle types affect translation effectiveness and speed:
