When compressing DTS-HD source file to mp4 (264 or 265) with source audio copied the resulting file does not show a snapshot tile in win10 file explorer. Audio is also muted during playback in PowerDVD (cinavia?) but not in dvdfab media player. When original source audio is AAC the the snapshot tile is visable. Additionally if mp4 of aac file is loaded up to Microsoft onedrive the snapshot is visable and the file can be played in preview mode without downloading. Why?
