Multicam Audio Channels: Where does my wav file go?
on Apr 7, 2015 at 4:09:04 pm

I have these ingredients:
1. Cam A video clip with camera mic sound
2. Cam B video clip with camera mic sound
3. Cam C video clip with camera mic sound
4. Discrete wav file with four tracks (three lavaliers + 1 boom mic)

I sync all of them together and create a multicam sequence.

Q. How does Premiere order my audio tracks?
Q. Is there a way to know where my discrete wav file will live?

I don’t want to get rid of any of my camera mic sound in case it captured something not captured by the discrete wav file.

Any help you can give me would be great.

Thanks,
Marissa

[Marissa Aroy] "Q. How does Premiere order my audio tracks?"

[Marissa Aroy] "Q. Is there a way to know where my discrete wav file will live?"

PPro places Video multicam sources in the order they are selected. Literally. if you click on Cam B, then A and then C then your mulitcam will have B as angle 1, A as angle 2, C as angle 3. After you have created your multicam you can re-order by using the "Edit Cameras" function - (put your multicam in the event viewer, choose the wrench icon in the the viewer, then select "edit cameras.") - but this will only effect where the video cameras are placed in the multicam matrix.

WAV files do not follow this rule. The crucial element for using WAV files is choosing the proper audio layout when creating your multiclip. After selecting your audio and video files and then hitting create multiclip you will get the "Create Multicamera" dialogue box. About halfway down there is an "Audio" area and the key is the "Sequence Settings" selector. I would suggest you choose "Camera 1" - this way your WAV file will be the default audio for the multiclip - in your case the 4 audio channels will be available whenever you want to add audio, they will be laid out in the order of the WAV file. You will not see the WAV file as an "angle" when viewing the multicamera clip in the source or program viewer, but if you select the multiclip in the browser and then right click and choose "open in timeline" you will see the WAV file tracks laid out as the first 4 tracks in the multiclip timeline. If you need to get back to the camera mic sound you can hit match frame (F key) once to pull pull up the multiclip, then a second time to pull up the original source clip, which you can then use to access your camera audio.

The other 2 choices for Audio layout - "All Cameras" and "Switch Audio" will place your WAV file as the last angle and it will be labeled as such in the event viewer. With these options you would have mulitclip access to both WAV and Camera audio in the multiclip but it can be a major PITA working this way, having to constantly switch off unwanted audio tracks and I don't think these would be appropriate for what you want, but you can experiment by creating a test multiclip using each of these options and then opening them in a timeline to see the results.

Herb,

This is a wonderful complete answer. Thank you. I resisted choosing "Camera 1" in the "Audio" area in the "Sequence Settings" because I didn't think you would be able to go back to the camera audio should you need it.

Thank you very much for your time and help. It will help me in the future. Unfortunately, I've already finished multi-cam-ing our clips (I chose all cameras and thus have the unfortunate task of having dozens of tracks of audio and trying to figure out what is what.

Gratefully yours,
Marissa

If you open up the multicam clips in the timeline you will see clearly how the audio is distributed. My guess is the first 6 channels will be the audio from the first 3 cameras, then the WAV file will be set on the final track as a single "Adaptive" track which means multiclip audio 7-10 will be WAV 1-4.

Good luck.

Hey Herb,

It looks like you have a great understanding of audio in Premiere Pro given this post as well as others I have read.

I have a major problem that I have lost days if not weeks trying to find a solution.

Here it goes:

I have: 2 cameras, and 8 audio tracks (polyphonic wav files for audio)

I create a mulitcam source sequence. I see all my audio is there. Great! Thats a good start.



Next I create a sequence from the mulitcam source sequence and the audio tracks get mixed down to 2 audio tracks (both the same). However I can still see 8 audio tracks but there is not audio on the files.



My biggest concern or question is:

I want to be able to place a mulitcam sequence (still allowing me to change angles etc) into a final project sequence or timeline while still having the ability to edit every audio track within the original mulitcam source file. Or better yet when i create a OMF of my final sequence - I should be able to see all the audio tracks needed for post production audio work in protools or other DAWs. As it would make since - one would never edit audio before the final cut and any editor would always need access to original audio files to put final touches on or export etc.

Do you know of a solution to this problem? In FCPX this is extremely easy and happens with hardly any effort. Not sure why premiere made this to be such a difficult workflow.

I really look forward to hearing your feedback on the subject and thanks so much in advance.

Daniel,

From looking at your timeline I'm guessing that each of your 2 camera clips has 4 channels of audio, for a total of 8 channels, and you are not using "double system" recorders for audio. If my assumption is correct then the following should help you.

When creating a multicam source in Ppro a dialogue box comes up taking you through various options. In the middle of that box you get to the audio section and the crucial thing here is the "Sequence Settings." There are 3 options here, "Camera 1", "All Cameras", and "Switch Audio." Looking at your timeline it's obvious (to me) that you chose "Camera 1" which is the worst possible choice for what you want to do. "Camera 1" only uses the audio from the first camera of your multicam source or the audio from a double-system audio recorder if one was used. Which is why all but the first 2 channels are muted in your multicam timeline. Camera 1 is perfect if only one camera is recording sound or if you are going with a separate audio recorder but is terrible for what you are trying to do.

All Cameras gives you all of the audio, in your case 8 channels, recorded onto 8 separate audio tracks in your timeline. If you want to work with all 8 tracks of audio all the time, this is the choice for you.

Switch Audio allows you to chose which of the original 8 tracks you want to hear recorded onto 4 tracks in your final timeline. That means that in your final timeline there will be audio sent to tracks 1-4 but you chose which of your two cameras those 4 tracks come from. And once edited into your timeline it is as simple to switch the audio between the two cameras as it is to switch the video.

Once a multicam timeline is made you cannot switch between these modes, so I would suggest you make a few sample mulitcam sources each of "All Cameras" and "Switch Audio" to determine which will work best for you.

Good luck.

Hey Herb,

Thanks so much for the response!

From your suggestions I have experienced with all Multicam scenarios. "All cameras" definitely is the best for what I'm trying to accomplish.

However, I still have the same issue - and more than likely i am missing something thats right in front of me.

I have no problem getting all of my audio tracks in the multi-cam source file. Even further I have no problem creating a sequence file from the multi-cam source file thanks to your notes advice...(Images below)





However - when i try and take clips from the newly created multi-cam sequence, the audio tracks are getting bounced down - not translating to my final sequence in which I would like for them to show up. I am also loosing a camera angle in the final sequence as well. (Image below)



Now - if i drag the original multi-cam source file or clips within that file to a final sequence (or any sequence for that matter) all of the tracks will be there as well the ability to switch angles. (image below)



This appears to be a strange problem - please let me know your thoughts on why or what i may be missing.

Thanks again Herb!

Hey Herb -

I think i figured it out!

SWITCH AUDIO is the best solution as with 4+ channel polyphonic wav files it keeps all embedded tracks in 1 4 channel track. This allows me to create a sequence from a multi-cam and all individual tracks are still in the sequence without being mixed down in any form. Also translates to other sequences built after making my initial cuts.

I can't say how thankful I am for your response and assistance on the matter as it led me to experimenting with those different options.

I do wish Adobe would allow for changes after a multi-cam is created and not force you to re-create it just to get a different type of audio layout - as i am sure this has caused many users much frustration. Hopefully they can allow for more flexibility down the road - especially since multi-cams are meant to be worked on in some form of nested or embedded tracks etc...allowing clean workflow in a final sequence...but then when you export a OMF for audio work you would be given all embedded audio tracks wether their in the final sequence or not.

thanks again!
