Thanks for your reply! I have seen this.
It is talking about sequences/timelines (which is a tiny bit different from clips). You cannot modify the number of tracks in a sequence once it’s been made. And merge clips seems to make a sequence that pretends to be a clip and defaults to a stereo mix. (an xml output and opening in FCP7 shows the merged clips as sequences instead of clips)
My workflow thus far has been:
1) import audio clips and video clips
2) select matching clips and use “Clip>Merge Clips”. This creates a new clip called “videofilename – Merged” which looks like a clip.
3) Mark ins and outs in the new merged clips
3) Select clips and go “File>Export Media” and select a preset (prores proxy 24bit uncompressed audio) But it will only allow 2 channel mono as an audio output.
4) Queue in media encoder. and watch as it outputs a mixdown of 4 mono audios into a stereo track no matter what.
Correction to my earlier post:
I CAN drag a clip from the source monitor into a sequence and get all channels of audio to appear as intended.
So editing within the project will turn out fine. I follow the instructions Duke posted above to make a multitrack sequence and can output that. But if I want to take these clips out of PP and bring them to anywhere else, I have a problem.
