Be aware of Premiere’s strange use of mono audio tracks!

The one thing to be aware of with premiere is the way that it treats mono audio tracks when editing. If you drag a stereo clip to a mono audio track (for example, music, or boom/lav tracks from a shoot) it will mix the two tracks together and make a mono track. 
 
•You can set the audio tracks to “Standard” or “Adaptive” and I think this will avoid that problem.  See this article for how to set up the different track types:
https://larryjordan.com/articles/adobe-premiere-pro-audio-track-types/
 
•When you are doing the final output, you’ll also need to make sure you are bringing the stereo mix onto a stereo track and make sure it’s panned left and right, otherwise it will be mono and louder than spec.

 

Preparing an OMF or AAF from Avid

•Please send an OMFI v2 export or AAF.
•Please remove all video from your sequence.
•Please provide audio handles of at least 30 frames, 5 or 10 seconds is even better.
•Audio should be EMBEDDED (unless we’ve discussed other options)

Gotchas!

•All audio files in your Non-Linear Editor should be of the same sample rate. If they are not, please convert them to the same sample rate prior to the AAF or OMFI v2 export process.

•Audio mixdown effects (audio suite) eliminate handles, so avoid when possible.

•If the audio media files you will be sending total more than 2GB in size, you will need to split the sequence into two or more AAFs or OMFs. You can either break the project up into smaller acts, or export a fewer number of channels at once. e.g, Channels 1-8 in the first AAF or OMF and 9-16 in the second.

Preparing an OMF from FinalCutPro 7

Make all the tracks to export “Audible” (select the little speaker icon to the lefty of the track). Go to File>Export>Audio to OMF. Set rate to 48KHz, Depth to 24, Handle Length to at least 2;00, include crossfade regions*, include levels and include pans. Hit OK. It’s that easy.

*We have seen OMFs from FCP fail if there are crossfades at 44.1 KHz. so it might be safer to leave out the crossfades if you have been working with mixed sample rates.

Preparing a Quicktime movie

Include one or more of these sync references:
•Timecode window.
•Visible 2-POP.
•Included sound is helpful.

•Export as QuickTime movie, not a referenced movie!
•Prefered Codecs

  1. ProResLT (no larger than 1080×740 please)
  2. H.264 of moderate quality will work and is small, but I’ll end up converting it to ProResLT

•Video frame rate should be 29.97, 23.976 or 25 fps for PAL. Please note: 24fps is film speed. Unless you are going back to film you shouldn’t be using 24fps.
