[Juan Salvo] “There is no way to keep the dolby-e intact when you are capturing.”
Why not? It is just a data stream embedded so you should be able to capture it into FCP and back out. Capture doesn’t re-encode PCM data.
In theory Dolby E was designed to be editable, but in practice I wouldn’t try it with FCP. Part of the problem is that FCP doesn’t pre roll the source before an insert, just does an instant start at the edit. This creates clicks in normal PCM audio as it needs to do a cross fade edit. With a Dolby E stream, the cross fade should be turned off on the tape machine, but even so, I wouldn’t recommend inserting into a Dolby E stream with FCP.
