Hi there
I am ecoding from an After Effects composition which contrains solely a .h264 MP4 with a timecode as an effect. I initially used AME to create these .h264s from Premiere Pro through imported .MXFs, no problem with the latter of these encodes.
So, each video is around 2 - 3 hours long (around 1-2GB each), with the exception of one which is 9 minutes long. This 9 minute long one is fine, no problem.
However, for all of the large videos, while the footage is fine, the audio is completely missing for all except the last hour (near enough exactly, plus or minus 2 seconds tops). On a couple of them, instead of silence, there is apparently a random section of the audio, about 1 second long, which is repeated, until one hour before the end.
So, I guess my question is, are there any export settings which could trigger this, or does anyone have any kind of idea? All very frustrating 
Thanks for any help in advance
Ian
