Raymo, maybe good news:
1. My BackyardEos save movie from Canon in AVI format.
2. AS!2 can convert MOV :
" MOV files and other compressed files are also supported when
FFmpeg executable is available to AS!2. In principle there are no file size limitations.
FFmpeg convert many types of movie.
"If you place an FFmpeg executable near autostakkert.exe, it will use this to automatically convert files it can't read (e.g. MOV files). You can download a Windows build for FFmpeg here."
