Re: [Avid-L2] Outputting Direct Audio to Same As Source QT from Avid?

So that sounds promising. Do you have any idea if the problems that can occur with audio filler when using QT Reference files is avoided exporting directly from Avid? In my recent tests if I exported directly from Avid the audio behaved correctly but when going the QT Ref route I had missing audio on the resulting file when played in FCP7. I have determined, to the best of my ability, that FCP7 handles these files differently than most other players but it seems like FCP7's handling of the file might be more representative of how other software/hardware will interpret the file on an ingest/playout server. YMMV but that's what it seems like to me. I'm hoping like my aforementioned tests indicated that I can use Avid 8.3+ to export directly and end up with individual channels that will play nice with all the various ingest/playout servers I have to deliver to.

Version 8.3+ exports multi channel (1 channel per 1 audio track). I have not tested it with 8.2.x

Over the years I've been asking about ways to export multichannel stems out of Avid. By and large the consensus has been to use QT Ref exports and then save a self contained .mov. Today I was reading a delivery preparation guide for something called Catapult HD. I'm not sure what the Catapult name is referring to. I googled but didn't find anything related to a playout server etc.... At any rate the guide mentions exporting a same as source out of Avid and setting the audio tab in the export settings to direct to get the multichannel stems out. I did this and it works. Have I just been mis interpreting things these past few years?

According to the guide Avid version 6.5.4-8 support multichannel outputs. The one downside I've see is the resulting audio is a single interleaved track, which I've mentioned in previous threads has been an issue for some networks I've delivered to. So have I really been jumping through the QT Ref hoops to then save as in QT Pro for no particular reason? At my main work location we didn't upgrade to Ver. 6.5 until recently so prior to that I had no choice. I remember in a thread a while back being told the only way to get multichannel stems out of Avid was QT Ref. I recall it mentioned that if they were stereo or 5.1 tracks that could be exported but a traditional multichannel stem layout wouldn't work. Was there a time prior to 6.5.4 when that was true? I remember that being a big feature I wanted to use but then finding out it would only work with the 5.1 etc.... tracks. Have I really been missing this ability all this time? Man sometimes I surprise myself.

Now the bigger question when using the Avid to export using direct out audio will that alleviate all the problems I've been having when the audio media starts with filler or ends up being a different duration than the video track? Even those these files play fine for me they don't always work for various ingest servers etc... So will a same as source Avid qt export using the direct audio setting make a file that is universally compatible to everything with the known exception of those networks that won't take interleaved audio?

I feel like my digital head has been in the sand.
