  • Running noise reduction on a multi cam sequence

    Posted by Shannon Rogers on November 5, 2014 at 9:42 pm

    I’m working on a project with a bunch of multi-cam edits and I merged my clips and selected the better audio and have edited them into the timeline already. I knew I would have to do some noise reduction later but it seems I’m unable to export these clips to Audition. The option is grayed out. If I export the entire sequence I can get these clips showing in audition but the capture noise print and reduction process are grayed out as well. The adaptive noise reduction isn’t a good choice here as there are a lot of short clips without run up time to adapt.

    Can I not do any audio editing other than Premier’s effects on a multi cam clip? Do I have to do all the audio processing before merging?

    In most instances, you don’t need audio as part of your multicam. I multicam video only and sync audio to that multicam sequence in a new timeline. The exception is obviously something where the audio NEEDS to follow video like cutting between anchors at a sporting event, etc.

    I would suggest bringing in the original full audio clips (or extracting the audio from the video clips if you’re using that) and noise reducing the full clips, then relinking them in Premiere, effectively replacing the noisy original audio.

    Audio processing time is minimal, as is the storage overhead to create a second version of a project’s audio in most cases.

    Thanks Angelo. So in your example you would go ahead and edit your camera changes with original audio then merge in the improved audio? I thought about this but in the process of editing my single multi cam clip became several smaller clips with various extractions removed. Do you know a fast workflow to then merge in the audio? Or should I correct the audio before running the multi cam process?

    Ideally you unlink the audio from the video and/or don’t include it in the multicam sequence to begin with. From there I edit in the timeline with the synced audio under the video and I cut to my heart’s content. Usually multicam is simple enough where I’m making mostly angle changes, extracts and so on so I don’t touch the source monitor until it’s time for b-roll.

    In your situation, you can open a multicam clip as a timeline sequence. Export each track of audio separately, noise reduce it, and drop it back into the multicam sequence overwriting the original audio. Super simple, no need to worry about relinking or hoping your cuts stay in tact.

    I know this is a year old, but I just want to thank you for your help, Angelo! I am very new to Premiere and video editing in general and this was a huge help. I have been looking everywhere for this answer!

    To others who are trying to edit audio from a multi camera sequence: Right click on your audio and click “Unlink,” then right click on it again and click “Render and Replace.” THEN you can right click on it and click “Edit Clip in Adobe Audition.” I was starting to think this wasn’t possible!
