Testing notes for MOV

Browser playback is uneven. Safari plays MOV; other browsers depend on the codec inside and on how the server labels the file. Convert to MP4 for anything shown on a web page.
Phone footage stores its orientation as a rotation flag instead of rotating the pixels. A pipeline that ignores the flag produces sideways video.
