We are in the processes of getting certified on DG Fastchannels' Drop Box.
I am using Episode Pro to do the encoding - and was provided a template by Flip 4 Mac which supposedly meets the DG Fastchannel SD specs. I uploaded a test and everything looked good except for the audio. It was too hot - at +5db. When I went to check my timeline in FCP - the audio there peaks at -10db, and the QT movie I exported and used to do the encode also peaked at -10db.
What I can't confirm is what the encode spits out (since VLC player doesn't have meters).
I did confirm that in my encoding setting in Episode Pro, the "Volume" setting is not checked. However, the channels is checked and is converting to "Stereo" even though what I'm exporting from FCP is a stereo mix.
