Hi, adowEm
The “Apply to all” feature currently has some issues, and we will continue to work on resolving them.
Additionally, regarding the two questions you raised last time: 1. To have the converted audio and video bitrate match the source, and 2. Audio quality being reduced when converting to HDR. We have resolved all issues except for matching the video bitrate with the source. During the conversion process, the video will be re-encoded, so some increase in bitrate is necessary to maintain the quality. I understand that you are concerned about the converted bitrate being too high, and I have also noticed this, which is planned for an upcoming update.
