audio channels

[Brian Barkley]

The Canon XL2 has 2 RCA outputs . . what is the problem?

[Angeline Hoffmann]

when I capture video/audio, I have only one channel. I not able to separate channel 1 and channel 2 audio on the timeline. For example–I have interview on Channel 2 and ambience on 1. It both comes into PPro together. Ambience is way too loud and I want to bring the background noise down.

I have the XL2 as well but I’m not sure I get what you’re asking, if you mean that you did an interview while music was playing in the background and it was recorded with the speaking of the subject then theres really nothing you can do other than maybe try to EQ out the music frequency as much as possible. Will be very difficult though.

If you mean something eles please let us know.

Hi Angeline…

this is one of those areas of PPro that vexes even veteran editors of various systems.

Premiere’s default behavior is to treat all audio as stereo.
If you look at your timeline on the left hand side, you will notice icons that look like little BOW TIES. these are actually 2 speakers. This represents a Stereo audio track. This is great for music. Not great for split channel recordings like yours.

There are a few workflows to deal with this.

One is to use a filter effect called FILL LEFT or alternately FILL RIGHT.

Drop one of the clips from your camera on to the timeline.

From the effects panel: add FILL LEFT to the audio. If you hear your mic’d audio and not the ambient track, then this is the correct choice. If not, UNDO and add FILL RIGHT.

Essentially, this technique just uses the Left or Right audio signal of the stereo pair on both of the stereo channels.

This should solve your problem, BUT there are other ways to handle this if you like.

Hope this helps,

Alex

Another way to accomplish the desired result is to select the clip in the bin, go to the clip menu and select audio options>source channel mappings.

A pop up will appear and you can choose how you want premiere to treat your audio. One caveat of this method is that once the audio is in a timeline changing the mapping won’t matter unless you pull the clip on to the sequence again.

You have to change the source channel mapping on the clip THEN drag it into your sequence.

Fantastic it worked. Wish I had thought about doing this earlier instead of wasting time trying to figure it out myself.
