Merge clips audio confusion

When I merge a stereo clip with a mono audio clip, the result is a clip with 5 mono channels... is this a bug?
Unfortunately, CC doesn't seem to allow autmotic breakup of stereo clips into mono any more, only into "stereo mapped to mono" (a 2 channel mono clip with another audio clips correctly merges into a 3 channel mono clip).

A just in case mention, according to Adobe documentation, Premiere Elements has a synchronize linked clip feature. But, I have not found it to work
as advertised for several versions now.
See Synchronize Linked Clip section in the following
Adobe Premiere Elements Help | Grouping, linking, and disabling clips
I posted a thread about this a while back related to 9, 10, and 11. Never got any feedback on that.
But, I know first hand, it has not worked for me as described or otherwise 9 through 13 on Windows 7, 8, or 8.1 64 bit.

Merged Clips Audio Issue

Trying this again, having a major problem since update working with merged clips. I merge all my video and audio clips in a pre-workflow project in premiere pro. Just got my footage back from the shoot, labeled and sync'd in the project.
Because Premiere doesn't allow you to have more than 1 project open at a time, I copied the files, closed the pre-workflow project and opened my feature film project I've been working from. Copied the merged clips bin, I click on a clip, video plays fine but there's no audio playback.
I try importing the files from the pre-workflow project using the import project feature, keep only the actual merged clips (as the rest of my project is this way) still no audio. I have cleaned my media cache, reset preferences, even uninstalled premiere and redownloaded. Problem persists.
Can you help me figure out what the issue is so I can get back to making progress on finishing this feature film project?
The only thing different I've done this time that I didn't do last time was copied the audio into the bin with the video clips and merged that way. Before was putting video clips into my master audio bin and merging. But I don't see how this could possibly be the problem.

Going to try, but here is my workflow and have not encountered any problems until this last P/U days footage. I've been doing things this way because I found having all files in the project was causing it to crash constantly when I was working. I have a new I7' processor IMac with 24 gigs of RAM. And since Premiere does not allow you to have multiple projects open at the same time (Wish this would change. Avid and FCP both allowed multiple projects) I have to do things this way.
Pre-workflow Project File
Label all Video and Audio files to match Scene #'/Takes
Set in points on all video and audio to reflect slate
Merge Clips
Working Project File
Import only Merged Clips into Project. Either via import or copy/paste
Now I've done this workflow from just about the very beginning. Deleting all of the original source video and all audio clips from my working project so only my bins containing my merged clips remain. Have had no problems and edit has been smooth. Did a pickup day last week, followed same steps as I've done in the past, imported the merged clips into my working project and the clips have the audio set to none by default. Now once I go into the sequence I can manually set it and it's there but I cannot play audio in the source monitor which is how I edit, there's no reason I should have to go back to the crappy FCP way of editing doing the copy and paste from a sequence.

Merged clips audio not playing

Is there a reason why my merged clips no longer play audio?
Also is there a way to batch merge clips? I had to individually sync my whole project one video/audio clip at a time...a little disappointing to do all that work and come back to my project where the audio won't play.

Might be a good idea for a feature request.
Adobe - Feature Request/Bug Report Form
On the not playing issue, I'm sort of stumped. It's just always worked for me, and it's not an issue I recall seeing reported here by others.
Maybe try recreating the merge?

After using Merge Clips in CS6, the resulting file now has two audio tracks

Hey guys,
I'm running into a weird problem after using the Merge Clips option. I have my video and audio selected, I've already moved the audio so they're both synced. It looks like this:
Then I use Merge Clips and pull the new file into a new sequence which in turn looks like this:
I checked the audio channels for both and apparently the merged file separated the left and right audio channels into two separate streams as opposed to using the single stream for both channels like the original.
Anyway to prevent it from doing this?

So according to Adobe's website: http://help.adobe.com/en_US/premierepro/cs/using/WS2bacbdf8d487e582-73725e6a12e5a6165d0-7f ff.html
At the very bottom they list limitations, one of which being "Merged clip audio results in mono track audio only."
Which I was familiar with before posting this. It doesn't seem however that the two tracks are mono it looks like they are two separate stereo tracks. If I mute one I still get audio in both speakers even though I muted the "right" track.
Here's what they look like in the audio mixer
The original only has the left most track.
I guess the only thing to do is just deal with it or render out each clip uncompressed to have that single audio channel.

Syncing Audio with Merge Clips option and OMF export question/issue

Hi,
In the past when I've edited video, when it came to syncing audio I always did it manually. This time, using Premiere Pro CC, I used the merge clips option, to speed up the syncing audio process, which was a huge time saver with excellent results.
The question/issue I have..is that when I get my OMF exported for my sound editor, will this screw anything up, since on the project file, it doesn't use the original audio file, but the one that was merged. And in the project list, I don't even need to have the original audio file listed, since it's already been merged into a clip, which I used in the project. I know it's the same file used, but will it mess anything up since a merged clip audio was used instead of just dragging the original track onto the timeline?
- Ken

A good way to know for sure (and therefore feel comfortable that you're doing the right thing) is to do a test OMF export, then open this in Audition. This ill show you exactly what you're exporting.

How do I edit a merged clip in Audition, that was created in premiere to correct the synchronisation, and have it all updated to the premiere clip?

Hello,
How do I edit a merged clip in Audition, that was created in premiere to correct the synchronisation, and have it all updated to the premiere clip?
I have tried several tutorials but these either:
- show correction in premiere sequence (which is not practical; given the huge number of files we have)
- or show the editing in audition of a sequence, not the clip.
We have started merging audio and video (removing the original audio during merge) but some of the merged clips are out of sync, so we need to correct manually, BUT we want to correct the merged clip, which may or may not end up being used, so we do not want to take it to the sequence as all we are doing is prepare the synced files for editing.
Any idea how I can correct the synchronisation in Audition?, when I right click on clip and select "Edit in Adobe Audition" I get a list of files but not a multitrack session where I can see my video and audio tracks.

if premiere pro doesn't sync your footage properly, and you have a huge number of files, you may want to look at pluraleyes. there is a demo, and if it works properly, it would save you time to have it done right the first time, instead of tracking down random merged clips with bad sync.
premiere will either export a complete sequence or "edit clip in audition". the edit clip will create a copy of the original audio and open that in audition. there is no dynamic link, its just an audio file open in two programs at the same time. since there is no dynamic link, its not possible to bring merged clips into audition.
Adobe Premiere Pro Help | Synchronizing audio and video with Merge Clips
Once created, the merged clip cannot be re-synchronized, or adjusted. You must make a new merged clip.
Merged clip audio results in mono track audio only.Final Cut Pro XML and AAF interchange formats are not supported.
this doesn't give me much hope that audition or any other adobe program outside of premiere will help you fix the problem merged clips.

Missing Audio with Merged Clips

I'm experienced a very confusion and frustating kink in clip merging process. I suspect other people have encountered it before, but I can't find where. I'll post tech details at the end.
I merged clips by marking an in point on the audio and an in point on the video. I placed both clips in to my timeline. I deleted the stereo track that came with the video. I linked the 4 mono channels to the video, and dragged them over to a bin, where it asked me to name the merged clip, and I named it according to the scene.
I had no problems working with them
Upon returning to my work, however, some of the audio seems to be missing. That is, the top of the four mono tracks is there, but the other three, while there in the timeline, play no sound - they don't have any waveforms anymore (it is not any kind of mute track issue, the waveforms themselves are gone).
I have since tried merging clips directly in the media browser, using in points, and this seems to resolve the problem. While I am happy to see a solution for the future, I am on a very tight deadline and don't have the time to re-merge all of my hundreds of clips.
This is an awful bug that Adobe has got to fix.
Thanks!

I created a new user account and trashed my preferences and I have the same problems. I created a new project, and new sequences. Same problems.
It only happens with 23.98 (batch reverse telecined using Cinema Tools) NTSC DV clips that have been merged with separate 24-bit 48 khz Quicktime audio clips (converted from BWF using BWF2XML). Clips that were captured from the tape with audio and video simultaneously don't have this problem. The discrepancies between the actual amounts trimmed and the white numbers in the trim windows are consistent. If it's off by 6:10 on a clip, every time I try to trim that clip it will be off by the same amount. But the number varies from clip to clip. It's generally 5-8 seconds.
If I try to trim only the audio, I don't have any trouble. If I trim the audio and video at the same time I don't have any trouble. It's only when I trim the video on its own. If I use the original video clip before it's merged with an audio track then it trims fine. If I cut the merged clip into a sequence then delete the audio track from the sequence the problem remains.

How do I get my merged clips to reconnect with their audio?

I am on FCP 7 syncing audio and video with ProRes 4444 @ 23.98. I am merging clips into bins labeled according to their scene. Pretty straight forward.
We then decided to go to ProRes 422 proxy to edit on a smaller faster drive at a lower cost. I transcoded the footage to 422 proxy with MPEG Streamclip same frame rate, same dimensions 1920x1080.
Next I go to relink the footage. Audio relinks and gives me this message: (Keep in mind these are copy and pasted files on the new hard drive).
"Some attributes of one or more of the files you have chosen do not match the attributes of the original.... The attributes that differed are as follows:
- Media start and end
Would you like to try to reconnect them again?"
Video relinks and gives me the same message, but adds "reel" as another attribute.
I've seen these messages before and nothing has come of it so I didn't think anything of it at first. Checking all the individual audio and video clips. Everything is playing fine.
THEN I go to play my merged clips... no audio!? Double click a merged clip in the browser, clip plays in the viewer but NO AUDIO. Right click on the merged clip file, select Item Properties and format. It is recognizing the correct audio clip that should be playing in the info there. I drag the clip into the timeline and I can see the shadow of the audio and video clip but when I let go in the timeline only the video appears.
How can this be?? What am I missing??
I would be so grateful for any ideas you might have!

What happens if you control click on the audio clip in the timeline and choose "reveal in finder?"

Merging clips turns stereo audio to mono

I've got a stereo audio file I'm merging with a RED Epic clip (with replace AV clip audio). Whether I merged by audio waveform or in point, the result is always a merged clip that has two channels, but is no longer stereo. It's like it has taken only the left channel and doubled it. Thoughts?

It's not a dual panned center mono file, there's something wrong with the way it sounds when left is panned hard left and right panned hard right. I've tried panning each channel hard the other way and it still doesn't sound like the original stereo file I've merged it with. Am I doing something wrong? Why wouldn't premiere just replace the AV clip audio with the singe track stereo clip? Why the need to break it out into dual mono? Is there a preference I'm missing or something? This seems unintuitive.

Merging clips results in several duplicate audio channels/tracks

I am trying to sync my audio and video in Premiere, and something is screwing it up.
I have my video track, that has 2 audio tracks.
Then I have my polyphonic wav file, that has 5 audio tracks.
2+5 = 7, right?
So why is it, when I merge my two clips together, that Premiere decides to create 20 additional tracks for my Merged Clip, totaling 27 tracks?! The majority of them are blank/empty/silent. Why is it doing this?

I don't understand this part of your explanation. It's been a while since I've used PE, since FCPX's sync and multicam features work so well.
Why not try a short test – skipping the PE steps entirely. Select two of your clips and let FCP automatically create a test multiclip matching the HVX waveforms with those on the 5D. Open in the Angle Editor – or start a test project and see whether the boom mic track is present.

FCP 7 "Merge Clips" Lost Audio

I export my audio from soundtrack (needed to fix noise) and I create an AIF file.. exports fine and plays in its entirety (in multiple different programs).. Import the AIF file into FCP 7 and the file plays fine in its entirety also... Then when I "Merge clips" the last 10% of audio goes dead when synced to video? same problem, multiple clips.. every time. any ideas?? I know from trying multiple different programs to play the audio that its a good working file. But the last minute or so of every clip has no audio playing.. but DOES show there is WAVEFORM??

I should have added that the video plays just fine in the preview panel above the checkboxes. Thanks for helping...

How do I make sure that CS5.5 Merge clips encodes Audio at correct volume?

Windows 7 x 64, 2 TB, 12 GB RAM,
I am using the Premiere Pro CS5.5 Trial (full version), particularly because of the new Merge clips feature.
The Merge clips works intuitively and easily; this is a fantastic advantage. I am creating these clips to use in Captivate 5.0.
But, when encoded, the Audio volume has blown out so that it shatters the ear drums.
I am not sure whether this is a PP problem, or an AME 5.5 problem.
A second problem is this with the Merge Clips. In the Project panel, if you check the Duration of a Merge clip (in PP) it shows the original duration even although it has been altered on the Timeline.
If I encode the video clip separately from the Audio, I can adjust the Audio volume in Captivate, but, this:
1) increases the overall file sizes-something I don't want for the web.
2) the video duration and the audio duration do not match, even though they did on the Timeline. This did not happen in CS5.
I know this is a new version, but has anyone any ideas that I might try. I have alread delayed my project waiting for CS5.5 to become available.

Sounds like Media Encoder is actually recording the audio as a stereo file but the audio is panned to one side.
Check that you haven't accidentally panned the audio in the mixer to one side.

Premiere Pro CC Update - Merge clips with audio works

Nice to be able to merge master audio with a clip using the audio merge option. Tried one video clip with master audio to see if the update fixed the bug and yes it did. Thanks to the guys in the back room at Adobe.

Just came on here to post about the buzzing transitions, glad to see it's been fixed already!
Another thing though I don't see mentioned, since moving to 7.2 I find audio playblack is out of sync while editing, and in some clips significantly more noticeably than others. This only happens during playback, if I pause and scrub manually, the audio is perfectly in sync. This actually messed up a project for a client. I thought the audio off the camera was out of sync in one segment so I bumped it a few frames before exporting. Didn't check it after of course and sent him the file, then got a reply back that it was out of sync in that spot. Check the exported video and sure enough, he was right. Check it again in project but it looks in sync. So I bump the audio back in the timeline so that it LOOKS out of sync again during playback, but the new exported video is perfectly in sync!
Editing a TV show now with hundreds of clips and it's maddening with some looking fine, some looking a little off, and some looking completely off and having to manually scrub to check and be sure along the way.
Hopefully this is also fixed in this update..will see tomorrow.

Merged clips and modified audio channels bug/issue

My problem is that if I create a merged clip and modify it's audio channels Premiere (both CC and CC2014) does not respect the modification under specific circumstances. These circumstances are: if I use keyboard shortcuts or the source window buttons for overwrite/insert to cut the merged clip into a timeline. However, if I drag & drop the clip from the source window or from a bin into the timeline Premiere will respect the audio channels set through modify audio channels.
Here are steps needed to create my problem. You will need a video clip and an audio clip with at least two channels to reproduce this.
1. Create a merged clip from the video and audio. Does not matter if you have "Remove audio from AV clip" enabled or not.
2. Right click on the merged clip in the bin and select Modify -> Audio Channels.
3. Set the merged clip's audio channels to Number of Audio Tracks: 1, Channel Format: Mono. Set the source channel for Audio 1 to anything except Channel 1. Click OK.
4. Make sure you have the merged clip open in the source monitor. Use keyboard shortcuts (. or ,) or the insert/overwrite buttons in the source monitor to cut the clip into a sequence.
5. The merged clip in the sequence will use channel 1 for audio, even though it has been set to use another channel.
6. Now try drag & dropping the merged clip from either the source monitor or from a bin into the sequence. It will now use the audio channel that has been set through modify audio channels.
My workaround is to use drag & drop for now for affected clips, but in the long run this is a pain in the backside.
My question is if this is something that affects other users as well. And while I'm waiting for a fix, if anyone has any suggestions on how to get modified audio channels to work properly, I will gladly listen.
I have filed a bug report for this. I have reproduced this on multiple Windows 7 machines with Premiere Pro CC and on two Macs with both CC and CC 2014.
EDIT to add: I have been in discussion with Rameez from Adobe about this through the support chat and have been told that this is working as intended. He suggested I post a thread about it to see how other editors feel about the functionality. I personally feel that the way it works now makes no sense at all. If others feel the same way, maybe this issue can be fixed in a future update. So please make your voice heard.
EDIT to add: In most usage this might not be an issue at all. But if for example you have external audio on multiple channels and to make sure you have a clean timeline, you wish to remove extra tracks from your merged clips and those extra tracks happen to be any track before the last one(s), you will find that editing the merged clip in in any other way than drag & dropping it in the sequence will result in you losing those last tracks instead of any tracks in the middle that you have disable through modify audio channels. I would think that the audio channel modifications should work no matter what way you cut the merged clip in.

When I merge clips the number of audio channels double

I have a .mov file from my 5diii that has stereo audio and a .wav mono file from my audio recorder.
When I drag a clip into a bin (for sorting) it merges the clip.
That merged clip now has 6 audio channels instead of 3.
It also happens if I select them and just choose merge from the menu.
Anyone know what's going on with this?

Simply dragging a clip to a bin shouldn't be merging anything. I've never heard of that behavior, and suspect some observer error on that one.
Do you intend to use the original camera audio?
