Dolby E into a QT Mov File?

[The Chinese]

Anyone have luck getting a Neyrinck Created Dolby E stream to work in a QT .mov file w/ ProRes Codec?

I can't imagine why that would work all that well. I'm sure it could be embedded but what players could decode it?

Perhaps the idea being to send it to FCP with the Dolby E Encoded for layback to HDCAM? In THEORY this would work, since the audio track on a Quicktime Movie can be 24/48 PCM. However, FCP could cause ALL sorts of nasties on playback, as it really doesn't do a good job of straight playout - it's almost always doing SOMETHING to the audio (level, dither, sr conversion), even without your knowing it - which as we all know, toasts a Dolby E stream. I think some folks have done a successful playout of Dolby E via FCP, but we certainly haven't managed it here.

In theory, Dolby E in a QT movie should work.
The problems occur more in the context in which Quicktime is used:
Onboard sound often adds SRC or volume change. FCP is tricky, also.
Audio synchronisation and playback has to be frame accurate ...
good luck,

Bernhard
