Match Source Audio Layout in Project Manager
Often Project Manager will fail to trim clips used in a sequence when performing a Consolidate/Transcode. This can result in massive amounts of unnecessary media being copied. The most common culprit is a mismatch between the source footage and transcode preset audio layout. "Match Source" should apply to the audio as well as the video when performing this operation. Obviously, there are some codecs that don't support certain audio layouts, but when transcoding to Quicktime Apple Pro Res or GoPro Cineform, this should not be an issue.
