turning off right channel in a quicktime movie

Greetings,

I am scoring a film and I have been given new reels where the dialogue and source music is in the left channel, and the temp score is in the right channel. Is there any way to turn off the right channel in Logic when I am scoring the reel? I want to still be able to reference the temp track, but I would like it off while working. Thank you.

Best,
Adam

Drag the movie file directly into logic arrange window. Logic will automatically add the audio from the movie on a stereo track. You can then bounce the track as split stereo file and re-import it as two mono tracks, giving you the control you want. Make sure you turn down the volume in the actual quicktime movie though!

I did this way and it definitely works. Thank you. However, if I want to adjust the tempo of my cue once I have reimported the audio, the temp track will no longer be in sync with the film. This is why I was hoping there would be a way to manually turn off the right channel of the quicktime movie. Are there any other options, or is this the only way- meaning, I will have to figure out the exact tempo of my cue before extracting the audio from the movie and then bouncing it as split files and reimporting it? It seems like there should be an easier way to do this.

Try locking the audio you've extracted and imported to a track using the command: "lock SMPTE position" It's in the local menu "regions". My key command for this is L. I can't remember if that's the factory default command or not.

You might want to separate the audio into two mono region/tracks too. I think it feels nicer to be able to have things centered.

Thank you. I guess this will have to do for now. Hopefully Logic will make new movie preferences that will allow you to manually turn off the L and R channels without having to extract audio.

Actually, you don't have to split the file - use the Gain plugin (->Helper) to pan to the desired channel, then use the Direction Mixer to center this channel with a Base setting of 0.

Yet another way is to route the interleaved stereo file you got by dragging the video into Logic from a stereo audio track to a mono bus. If you now pan the stereo track L you'll get dialogue only, centered, if you pan it R you'll get temp track only, centered.

If you make a copy of the audio track and pan the first one L, the second one R, you can mute or solo dialogue and temp music independently. Advantage is you don't have to bounce a separate split stereo file, so you'll have only one dialogue/temp music audio file in your drive.

Good luck with the score!
