CS5 MultiCam audio

Happy with working MultiCam editing in CS5 (fully up to date under Win7 Pro 64), but have run into an issue with getting the sound I want.
I have two cameras synced up in the source sequence. Coverage by two cameras is not continuous, but there is always at least one on the go.
My master sound camera (Audio 2) starts after a couple of minutes of useful footage from the other, so I want Audio 1 for a short while, then Audio 2 - with freedom to change picture camera independently of the audio switch.
With no audio on Audio 2 at the start of the source timeline, I could not get the audio to switch to Audio 2 anywhere during the MultiCam edit. When I copied and pasted audio into the start of the source Audio 2 track, subsequent MultiCam editing worked as expected. Is this a known issue/bug?
In trying a workaround, I set up a submix track in the source sequence, but then found that there was no way to reference the submix in the MultiCam sequence. Do those who use MultiCam more than I do have any thoughts in this area? Is it worth a feature request?
Or is all the above down to finger trouble?

Thanks for the replies.
I solved my problem by backfilling track 2 to the start of the source sequence, which then allowed me to successfully select Track 2 in the multicam sequence. This suggests that davidbeisner2010 in the first reply is not describing accurately what happens in CS5.
I would still like to see the multicam sequence include an option to take a submix from the source and will be submitting a feature request to that effect and also to suggest that audio track swapping in the multicam sequence is facilitated separately from the pictures. This would give much more flexibility in dealing with multicam edits.

CC 2014 multicamera audio problems

Hi everyone!
I read about some problems with multicamera but in this new version (CC 2014) is the first time I worked in multicamera and I'm having some trange problems with audio, and I dont know if it is a bug or something.
I´m in a full HD 29,97 project with 3 cameras and because some audio effects and have in the source 2 audio tracks. In this áudio tracks I have some fade in/outs and
most of the time just to normalize gain. I mean that somethimes theres is a "contínuos cut" in same track or not.
When in multicamera mode, select main áudio (1 track result from the source 2 tracks) and after finish I insert some vídeo in some places and did some cuts.
The problem is that when playing the final multicamera the áudio (that I didnt cut or edit) is no the same, in some situations, that is in the souce timeline.
Per example, in source there is a situation with the end a playback music (áudio track 2) and when another clip came with somebody talking (áudio track 1).
To reduce the cut evidence I "cross" the sounds with fade out (track 2) and a fade in (track 1) and at the source timeline everything fine. But in multicamera timeline
that point of the áudio result in more "áudio" that dont belong to that point. In this example is a fade out/ fade in 30 frames crossed in diferente timelines and other sounds appear. Very strange!!!
I did some test and if I just eliminate de fades the sound in multicamera is ok but notice that was a cut sound. So, I think that the fade in and fade outs in multicamera
are the main responsables for this problem that apparently is some bug, dont you think?
Now I have this problem to export with almost to hours and there are many situations like that one I refer like an example.
Someone had this problem and know what is wrong?

Adobe Media Encoder cs5 - No audio

I am using Adobe Media Encoder cs5 version 5.0.1.0 on a Windows XP Service Pack 3 32-bit machine. None of the wmv or avi files I try to encode have the audio track encoded. I have tried encoding with both the "F4V - Match Source Attributes" and "FLV - Web 640 x 480" presets. Neither of these encode the audio output at all. The audio track plays correctly in Windows Media Player. Has anyone else had this problem?

Very interesting data, Wayne. Very interesting.
> I am not sure how to encode to the other formats using AME, so I could not complete these tests.
Sorry, that's my fault. Ignore that test. I didn't realize you are using the Web Premium suite. The other formats I referred to are only available if you have Premiere Pro, After Effects, or the Production Premium suite installed. (I knew this by subconscious deduction, actually, since those products require a 64-bit version of Windows 7 or Vista and you stated that you're on XP 32-bit. It just didn't trickle out to my conscious brain.)
Let's back off for a second and review what we know. Please correct me if I'm wrong about any of these points.
You have WMV and AVI source video files. The audio in the AVI files is encoded as PCM or MP3.
You can hear the audio in these files when you play them in Windows Media Player.
Encoding these files to FLV, F4V, or H.264 appears to complete successfully in AME CS5.
You can not hear the audio of the encoded files in Windows Media Player, Adobe Media Player, or VLC.
Inspecting the encoded files in VLC and Audacity shows both that an audio track exists and that there is a waveform in that track.
Using a different user account on the same machine does not exhibit the problem.
Encoding your source files on a different machine using AME CS4 (your colleague) or AME CS5.5 (my computer, with the sample you posted) does not exhibit the problem.
So, yes, this is most intriguing. The difference in your ability to hear your source files but not the encoded files is most curious.
I do wonder:
If you take one of your encoded files to a different machine, does the audio play? (If you post a sample, I'll try it here.)
Since Audacity shows a waveform for the encoded files, can your hear the audio in that application?
The only thing I can think of that is unique about the formats that you are using AME to encode to (FLV, F4V, and H.264) is that those formats all use compressed audio. MP3 in the FLV format, and AAC in F4V and H.264. (FYI - F4V is simply H.264 insided of a Flash video wrapper.) What could be unique under your user account related to that? I don't know. Possibly if there is a utility on your machine related to compressed audio, that might be intercepting the audio stream in some way. Do you have any software designed for capturing compressed audio from the Internet? Or it could be related to the audio card drivers on your machine.
It might be worth sniffing around the %appdata% folder on your account and temporarily disposing of the folders for other programs. If you can isolate something that way, you may be on the right path.
You might also want to run msconfig (Start > Run > msconfig) to disable background applications and services that could be hijacking the audio. Go to the Startup tab there, clear everything, reboot, and see what happens. If that works, start putting the services back one-by-one until you find the culprit.

Why does Premiere Pro CS5 process audio source before exporting clip in AME CS5?

Hello everyone, my first post here. I am currently trying out the trial CS5 Master Collection on my MacBook Pro. I've been using Premiere Pro CS5 to put together family videos. I select a certain portion of a sequence and queue it for export in Media Encoder CS5 in the format H.264 for iPod with video and audio.
Now in AME I have a queue list of about 5 clips from the sequence. But when I hit the Start Queue button, the bottom left of the progress bar states "Adobe Premiere Pro processing audio source from [then file name]" for all 5 clips from the sequence then creates the first output file.
Then it moves to encode the second and again states "Adobe Premiere Pro processing audio source from [then file name]" for all 5 clips of mt sequence then spits out only the second output file.
This continues for the remaining 3 output files. The total sequence length is ~32 minutes with transitions and it takes about 35 minutes to export which is all consumed by the process audio source of the 5 clips in my sequence for 5 separate times.
Is there a certain reason why Media Encoder or Premiere Pro does this process of audio source? Is this process necessary or needed? I experimented with choosing different output formats but the results are the same. Any help would be appreciated, thanks.

Now that's pretty good follow-up to your first post, and quickly too! Nice detective work.
As you have found, there is basically a Render/Replace operation going on in PrPro, to get the material in the correct form for AME.
Thank you for reporting, as it saved me, and others, from basically saying what you said.
Good luck, and sorry that you beat us to the punch.

ENCORE CS5.5: Audio Conforming Is Eating Up My Hard Drive

Hi guys. I am using Adobe Encore CS5.5 (Windows 7) for a DVD project. My project is pretty much a series of audio files synch with .PSD images. In other words, I do not use real video. Rather, I Use Images wity audio running in the bagground of the timelines.
Encore keeps conforming (non-stop) the audio files of my project, and it's eating up my hard drive space at lightning speed, say 537GB of free space in like 30 mins or so.
After much research, I found that the Media Cache Files Folder is being loaded with replicas of my audio files with the following extensions .ac3 48000.cfa and .ac3 48000.pek
I use seperate hard drives for both my C: drive (for software) and D: (for my project files files). As I stated above, I have plenty of room in my C drive, but Encore keeps eating up the free space, this, of course, while I have my project running.
I resaved the project with a different name. I even re-installed Encore, and the result is the same: Audio keeps conforming and the Media Cache Folder is loaded. When I empty this folder, I get my HD space back, but the process keeps on going. For those who do not know, the Media Cache Folder can be accessed in Encore from Edit--> Preferences-->General -->Media: Media Cache Files --> Browse or directly from C:/Users/Username/AppData/Roaming/Adobe/Common/Media Files, where "Username" is your Computer's User Account name.
This is by Far the most annoying software glitch I have ever seen in my life. I am so frustrated. My project is quite complex and I don't want to start all over again. Any help or insight will be greatly appreciated.

Thanks for your reply.
I have 6 timelines. The total program length, as shown in the build tab, is about 3GB used. And it's a DVD project, not BD.
I use MP3 files and I can see the audio keeps conforming from the Progress tab. There's a Stop button,but it's grayed out, so I can't stop it. The setting I am using to transcode is a3c as you mentioned.
The funny thing is that I even deleted the project's audio files from the timelines and Project Assets as well. At this point the audio files don't even exist in my project, and yet the Progress tab shows the audio keeps conforming and my hard drive keeps being swallowed by this monster. That's driving me Nuts!
Originally, and of course, the audio was Untranscoded. I performed the transcoding and yes, PSD images are brought directly as asssets into Encore. I probably should have done this from Premiere, but a) I have never used Premiere, and b) I was just learning how to use Encore by watching some video tutorials.
The thing is that my project was complete and everything was set, including audio conforming. I even outputed a disk image, which I then burned into a DVD. At the time I did this my project was still somewhat small as I just wanted to test the whole process with just a few files. The thing is that at this point I didn't realize what was happening in the background with my hard drive's free space until I later got a Windows warning message of low disk space. And that's when the saga began for me.
Once again, thanks for your help.

Ineffective Multicam Audio Sync in PPro CC (PluralEyes wins every time)

I was excited to try the multicam sync using audio in Premiere CC but unfortunately I've found that it has very limited success. I regularly run shoots of 4 cameras with each having several clips, and when I try to sync them in Premiere only a few actually get syncronized. PluralEyes still does a markedly better job and sync all the clips, not just a few. Any tips or tricks I'm missing?

For starters, PP will only sync one clip per track, so if you wish to use this feature, you'll need to shoot continuously, no stopping until the event is over.
Secondly, the feature doesn't seem to work very well (at all?) when including a separate audio track in the mix, so use video clips only.
Thirdly, it is a new feature for Premiere Pro, and will likely get better over time.

Converting NTSC to PAL in CS5, the audio is out of sync-too slow. What do I need to adjust?

Hi. I had to purchase a new Sony video camera in USA (NTSC 29.9fps). We are PAL, so most of my holiday movie is PAL 16:9 widescreen. When I imported the clips from the NTSC camera, I converted the clips to PAL 25fps but the audio is out of sync and appears to be too slow. eg. a male voice is high pitched and not quite audible. Is it the 'bit rate' difference causing the problem and if so, how do I change that in CS5? The PAL clips off my old camera are imported as MPG files. The new camera files are MTS. I am not sure if this is important but would appreciate some help. Thanks.

Adobe doesn't have any tools that perform adequate NTSC<=>PAL conversions, in my view. You may be better off creating a separate video for the NTSC stuff, keeping it as NTSC. Your player should be able to handle it fine.

Premiere Pro CS5 skipping audio error

Anyone come across this:
When trying to edit an AIFF audio file in the Premiere Pro timeline, the audio skips when playing back,
meaning that after a few seconds it just skips several seconds and starts playing a different part further on in the same AIFF...
The indicator bar does not visually "skip": just moves on steady as it should.
Related to this:
I have a project that was converted from After Effects CS4 to CS5, that shows the following strange behaviour in CS5:
The comps contain layers that consist of AIFF audio files. When doing an audio preview (.) or a RAM preview, the audio does not play the part of the AIFF file that, according to the time-code, it should play. It starts where it should, but then suddenly it skips a few seconds to another part of the AIFF. All that while the red indicator bar suggests it is still playing lineair as it should (the red line does not "skip" to another point.
This leaves me with an unworkable situation, as it is quite unpredictable which part of the audio will play right...
As far as i can tell this behaviour only happens with a converted project (CS4 > CS5) in After Effects.
But when I started a new project in Premiere Pro I got the same skipping audio with a totally new project!
Converted back to CS4 for now.

Mark,
Your observations are probably spot on. I cannot only comment through PrPro 2.0, so changes could certainly have occurred. I do know that CS4 changed a lot, regarding Audio.
In my CS2 Production Studio version, I have had up to 22 Timelines/Sequences and most have had from 6 to 24 Audio Tracks, with a DD 5.1 SS Master Track. I have had zero issues with any Audio dropouts. Now, I have had issues with Playback stopping and at totally random spots, and this has happened with very simple to very complex Sequences, and different spots. Sometimes, this has happened with a fresh boot and Project load, but also after many hours of editing. These halts come and go. I've had them happen a dozen times in a row, only to then disappear in that editing session. I've had sessions that lasted for days, with not one, only to fire up the program, and get 3 halts in a row. That has been my only, even moderately similar experience.
Wish I could comment on later versions, but I cannot.
Thanks for your observations and for reporting,
Hunt

Multicam audio levels/meters??? - Premiere CS6

Is there a way to see the audio meters while in the multicam window?
The audio plays fine but is there really no way to monitor the audio to see if its peaking or not, or what level its at, unless I stop the multicam and play it in the timeline?
All the source clips, all the timeline clips, all the project window clips all enable the audio levels/meters.
Why not the multicam? Seems odd.

Audio is the other half of what editors deal with so I kinda do need to worry about it.
Agreed. Just not from the MC window, but from the sequence where you can actually make changes and adjust things.
Then why do the audio meters work when playing clips in the project window? Yes, the sequence is where changes are made but being able to monitor what a clip looks like or sounds like outside of the timeline is essential to any good NLE. It's not editing, it's monitoring. Just an oversight on Premiere Pro's design that I hope they fix asap.
Jim Simon wrote:
I'm starting to learn that you are the king of "that's not what I care about so it must not be important".
It's actually more often a "how can I get this job done with the tools and features that are available to me right now" kind of attitude.
While that's a practical approach and certainly one that will cut down on stress, that's also the mindset that allowed for companies like RIM (Blackberry) to fall behind their competitors. I prefer a more "work with what you've got but if something's missing or broken, speak up" approach. My hope is that the PPro design team actually listens to their users to make it better. We all have things we wish would improve or be fixed and if we all just said "eh, it is what it is" then nothing would ever improve. I'm more of a "if it ain't broke, don't fix it...but if it is, then stop making excuses and fix it". I know the absence of something as simple as audio meters doesn't mean mulitcam is broken, but its an example of an oversight on the part of Premiere's design team that I hope they fix. It's a very simple feature. Every other NLE I've worked with has it. It helps the workflow especially with long multicam sequences. There's no reason it shouldn't work like it does if you play a clip anywhere else. Now its just a matter of if they care enough to fix it.
Truthfully, I was hoping it was just a glitch with my computer and someone was going to chime in and say "it works for me" and I'd have to re-install or something and then it would work. But I guess not. We all work with the tools and features that are available to us right now, but if adding a functionality that should have been there from the beginning can speed up my workflow then I'll gladly be the squeeky wheel.

Media Encoder CS5.5 Audio being converted into white noise

I have recently started getting an intermittent problem where some video files are being encoded to FLV with the picture looking fine, but the sound coming out as white noise.
The file used for the encoding looks and sound fine in every other app i have. I have been using the same preset within ME to create all the files for our website, for years!.It should be stereo 96kbps MPEG 3 but all i get is static.
The source videos are all edited , mixed and output the same way too.
The files being sent to Encoder are on Mac 10.6.5, and were created in Final Cut Pro using the Prores422 codec, with audio as Linear PCM 16bit/48khz
I have just rebooted the mac, installed the latest CS5.5 upgrades, repaired permissions, but still the problem persists.
Can anyone suggest a solution?

seems i did answer this myself last year!
i need to re-ecode the source material in a format other than 10bit uncompressed for Encoder to be happy with it. I thought the file was already Prores - must be an older file thats causing the trouble.

CS5.5 audio will not play upon start up

I am using a Mac. This doesn;t happen every time, but more than 60% of the time it does. When I start up CS5.5, I can see my audio and past sessions when I open them, but nothing will play in Multitrack or single mode. The only fix I have been able to come up with is, if I create a new recording and hit "Record"... CS5.5 will start recording. After I hit stop, then and only then will all my files start to play. I've tried to play from the space bar, as well as clicking on the play buttons. Can someone help me figure this out?
FYI _ I am aware of the Hardware settings and have checked all of those. I can't see any issues with them as it relates to this problem.
Thanks

Hi,
Try downloading and installing a basic codec pack such as the one on the link below - if you do try this one, just accept the default setting during the installation.
http://www.codecguide.com/download_k-lite_codec_pack_basic.htm
When the installation has completed, restart the notebook.

Adjust multicam audio phase/timing

Hi All
I do lots of multicam concerts, and don't have genlock or timeslave on my cameras. Therefore the audio in my multicam sequences is often out of sync by a fraction of a frame. About half the time, this creates a noticeable "phase" effect when I mix audio from two or more cameras. Is there a way I can nudge the timing of the audio on one track by a fraction of a frame, in order to eliminate the effect? A similar phenomenon occurs on audio from a single camera, when the audio is coming through different sources (e.g. A1 from a wireless on stage, passing through a mixer, alongside A2 from a shotgun, wired straight into the camera). I'd really like to pull this off without a round-trip to Audition. (I am using
PrPro CS6 on Win7)
Thanks!

If you check Show Audio Time Units in the sequence flyout menu, you will be able to nudge audio clips at the sample level.

Multicam - audio track not indicating source

In CS6 I could keep track of which audio track I was using in a multi-cam edit by the indicators on the audio part of the clip - MC1, MC2 etc
This is no longer a part of CC, only the video component shows the camera source.
Is there any way of getting the indicators back on the audio?
Multicam in CC does do some odd things occasionally with audio, changing the audio source sometimes even though I have 'multi-camera audio follows video' deselected

If you're talking about the source select tabs, in order for them to show there has to be a clip with audio loaded in the Viewer window.

Multicam audio

I'm a long time user of FCP 7 but I'm new to FCP X. I've now spent two days searching tutorials and help pages for an answer to no avail.
I'm running a small studio where we're doing many, many on-set three camera interviews (Cam 1, Cam 2 and Cam 3). All the audio is on the interviewee's camera - Cam 3.
I'm good with creating multicam clips, I'm good with designating all the audo from Cam 3 and I'm good with selecting "Video Only" so I'm just cutting the video between Cams 1, 2 and 3 while keeping the audio from Cam 3 throughout.
My problem is that although the Cam 3 audio is continuous, there's a break in the track every time I switch video between Cams 1, 2 and 3. That makes it time consuming to adjust audio levels.
My work around has been detaching the audio from Cam 3. Works great but as I edit the interviews it introduces the possibility of messing up my audio synch. What am I doing wrong?
TIA,
Peter

My problem is that I'm checkerboarding a discussion; lowering the level on the person who isn't speaking when they're silent. Changes to volume aren't likely to be global but to follow the back and forth of the discussion. Someone who's excited might interject at a high volume then lower that volume when they have the floor. That adjustment in volume often spans a cut from one camera to another. Ideally, the audio track would be continuous and not chopped up into little pieces. I'm beginning to think that the only solution is to detach the audio.

Serious CS5+6 Audio out of sync on MP4 and Quicktime HD (AC3/AAC) export problem

Hello,
while exporting our video files and importing them into our projects to check the sync we noticed that if we export in MP4 1080p H264 format the audio is 1/2 video frame out of sync compared to the original. This happens with both original audio files attached to the original clip as well as other random audio files combined with the clip.
If we export the WAV file and import it again into the original timeline this is 100% in sync, but if we export that clip with the imported WAV file it's again out of sync.
please check the pic:
as you can see the "edit_1080p_1.mp4" files is the exported and re-imported clip, which is 100% synced to the video (from timecode 0:00:00:00) and the our of sync is about half a video frame.
This also seems to happen in CS5 as we just have tested on another old system.
Addon: It also happens with Quicktime HD Export.
If exported in AVI there is no out-of-sync, so this problem seems only to be on Dolby Digital and AAC encoded and multiplexed files.
As we found out if exporting clips with any CS5 or CS6 Version in mutiplexed AC3 format eveytime after re-importing those files back into Premiere the audio is about 1/2 videoframe delayed! So this means if you work with multiple temporary exported files, e.g. MP4 HD HQ formats your audio gets more and more out of sync.
But we also found out that if you simply convert WAV to AC3 there is also a slight delay on the AC3 file, although not noticeable on the first view, but if you switch to audio frames view it's about 1/10 frame.
I think this is a very serious error and needs to be fixed as soon as possible.
Nachricht geändert durch pinklemos

And another, even worse, update:
we did several tests with just converting the H264/PCM multiplexed file to different format, MPEG2/MP2, MPEG2/AC3, MP4/AAC (both CS6 and CS5) and we just encoded the file with Procoder in H264/AAC (orange colored). And the result was, that ALL Adobe encoded files are not correctly synced to the original but the Procoder file is! Even with CS5 this was already not working.
I am shocked, that nobody really seems to have noticed that elemental error until now...
So the only working workflow at the moment is to export all files into Quicktime H264/PCM format and then user other encoders to create the final files needed, if they need to have compressed audio formats like MP2, ACC or AC3.
