Apple Compressor - Source Timecode not preserved when making AC3 file
on Dec 8, 2011 at 7:27:58 am

First of all, this is my first time using Compressor so it is very likely that I have overlooked the obvious!

I have created an AC3 Dolby Digital file in 5.1 from 6 wav files.
All has gone well and I can successfully create the file and play it back, when reimported, via the preview window.
My original 6 wav files all contain identical source timecodes.
The resulting AC3 file does not appear to have preserved the source timecode.
The preview window displays the timecode as starting from 00.00.00.00
I have also imported the AC3 file into Final Cut Pro and confirmed that the timecode starts at Zero.
My six original WAV files definitely have timecode.

I cannot find any setting in Compressor that will let me alter the resulting file's timecode.
If anybody could tell me what I have done wrong I would be very grateful.
Thanks in advance

Adam

[Adam Rickets] "I cannot find any setting in Compressor that will let me alter the resulting file's timecode."

My question would be: why? Why would you need to do this? I am curious, but I assume that AC3 files created this way don't have a timecode track, and it's just written by whatever application it goes to next.

The reason that I would like to keep the original source timecode is that I have to deliver the AC3 file to the editor so that he can import it into Final Cut Pro.
The Dolby Digital (AC3) format does have the ability to contain timecode, however it would seem that Compressor disregards the source timecode and creates a new code starting at 00.00.00.00
I would like to know if there is any way to keep the source timecode in the resulting AC3 file using Compressor.
Many thanks

Adam

There is no reason I can think of at all to give a FCP editor an AC3 file. Just pass your editor the WAVs and be done.
