Preserving AC3 passthru when exporting
Hello all,
I have a movie file, extension .m4v that I made from HandBrake on the AppleTV 2 setting, and the only audio info included in this file is the AC3 passthrough track (which is 5.1 surround). I wanted to set a poster frame for the movie, and I did, but then it asked me to save the movie file. So I did, but the new movie was only in 2-channel stereo. So now I'm thinking I should set the poster frame, but instead of saving, I should export it.
My question: is there a way to export this file and maintain the AC3 passthrough track without having to convert it? Or, a more to-the-point question, is there a way to add a poster frame to a movie file without having to convert the AC3 track into something else?
Thanks for all your help!
