Tool to Remove Audio Tracks from P2 Footage

[muzicman82]

Hi all,


We shoot with an HPX-500. Sometimes on 3-4 cameras. We use Adobe Premiere Pro CS5.5 for editing, which is pretty amazing with MXF files.


I am wondering if there is a 3rd party program out there that will remove audio tracks from clips. Why? We usually have a master audio track either multitracked or on a different system. I only need one reference track typically, so the other three tracks that get recorded are just wasting space. Additionally, I think Premiere may try reading all four tracks in the footage whether they are in the sequence or not, which I imagine increases disk activity and slows down performance, especially when there are 4 cameras involved.


Now, I know how I could do this manually by removing the audio track XML data, but I'd have to do that for EVERY XML file.


I do know that if I export MXF from Premiere Pro, I get 2-channel audio.


Any ideas?

Any ideas anyone?

I'm not sure how the 500 stores data, but my 370 saves the video and audio files separately, so you can just delete the empty channels manually if you don't want them.
If the audio is embedded, the only way would be to transcode the files, and export without audio.

The 500 does P2 MXF the same way. But you can't just delete the WAV files. The XML files will then go looking for them and NLEs will have a fit that the clips are corrupt. If such a tool exists, I think it would remove the references to the WAV files from the XMLs.

Not exactly an answer to your question, but using DVFilm Raylight Ultra with Vegas gives you the option to bring in either two or four tracks. Maybe Marcus could be persuaded to do something along the lines you need?

Did you ever figure this out? Two things I do:

1: Unlink clip, select 3 audio tracks, delete, select audio+video, link clips
2: There is a way in Premiere to just import the track you want but I don't remember how it works & don't have Premiere running at the moment. Seems like you have to specify it for each clip as it's imported which means dropping a batch of clips into Premiere would not accomplish your goal.
