I've had this come back with certain ingest servers. My solution was to do mixdowns in MC so I have a top-to-tail chunk of audio matching the length of the video track for every audio channel I want in the QT. Audio mixdowns don't take too long, even for long program stuff. Once I had those, I replace the short audio in sequence with the mixdowns, export ref QT, save as self-contained, and I'm done.

Delivering season 5 and suddenly there are issues with the files I deliver because the audio tracks aren't the same length as the video. Cutting on Avid SNDX Mac OS 10.6.8 Ver. 5.5.4. I export QT Ref from Avid 1080I 59.94 project with 4 tracks of audio from the pro tools stems for the program and tone from Avid generation all 16 bit audio. I open the Ref QT in QT Pro 7.6.6 and save as. Everything ama links back into Avid with proper levels etc... This season I'm being told the last to sections which are alternate credit sections with no audio can't be ingested because they have no audio tracks. I look in QT pro and the audio track durations are not the same as the video. They differ by a few minutes because the last two credit section are MOS. This has never been an issue before but the network engineers told me they have changed their workflow regarding integrating closed captioning. Whatever change this made they have issue with the last sections having no audio tracks. My solution was to add a one frame audio blip and slate 10 secs after program ends. Now the audio track durations are the same duration when viewing cmd J in QT Pro. Actually they are 1 frame different on the Ref QT but once saved as to a self contained file they are the same duration. They seem to be able to ingest the regular program which has filler in the audio after bars and before program start but not the end sections. I'm waiting to hear back once the network gets the new files if the blip solves the issue. I figure if it's filler audio that's the problem they would probably have issues at the start of the show where it's filler up to the first frame of program but perhaps that doesn't matter given they don't ingest that. I don't know if they ingest the slate along with the program. I would like to think they do but I'm not familiar with their hardware or workflow. The only other option would to be to get silent tracks from protools that I could slug into the filler. I hope I don't have to resort to that. Whatever hardware/software that changed in their workflow has had an effect on ingest without active audio tracks for some reason. Anybody got any light to shed on this.This kind or reminds me of issues a few years back with cameras that would not evenly stop the audio and video recordings to their files and Avid would balk when the two tracks didn't match in duration but I doubt it's for the same reason on the ingest server.
