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.

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.

Premerie Pro CC - have sound on timeline, yet when I export file i am missing sound in one tiny clip. Can I be related to working with Merged clips?

Hello Premerie Pro CC community,
I need help, I am working with merged clips (the video footage shoot with a DSLR and different audio recorders). I have a timeline in premerie with sound all finished. Everything was fine until I when and fine tuned some of the audio, just added key frames to correct and now when I export my sequence I am missing sound in one little clip of the entire mov.
Does it have to do with sound and editing with a merged clip?
I have tried to export in several different settings and still the same result, and when I look at my timeline the sound is all there.
I have until the end of Monday to figure what I have done incorrect
thanks
-DragonFly

In case it is a phase problem, try adding fill left effect to the faulty clip.

Out of sync indicator with merged clips?

Hi. I'll edit a fifteen minutes short film soon and I'd like to work with Première CC.
The film will be shooted with the new Sony F55 so I'll have to manage RAW files and xavHD files. I made some tests and Premiere read them perfectly.
But ... My problem is this:
I'll use the automatic audi sync to match my audio and my video. Then I'll merge them to have synced files.
I noticed that, once merged, there is no more out of sync indicator! Or is it?
I can't edit a complete short film if I don't have the out of sync indicator. It would be too dangerous.
It means that I'll have to work with the dinausor fcp7 with transcoded Applepro res files ... again!
I read that I could use Pluraleyes first, then bring the synchronized rushes into Premiere CC. But I think that it's a little bit stupid to be obliged to spend 200 euros and to loose time copying all the rushes knowing that Premiere could do it immediately
Any solution?
Thanx for help
Marc

That's not the only thing missing with merged clips. Copied from my previous discussion:
No Match Frame
No Replace Edits (picture matches, but audio gets out of sync)
And for that matter, NO out-of-sync indicators at all. None.
No making SUBCLIPS in the project panel (via source panel ins and outs). A subclip gets created, but it's not the part you selected.
No retention of MARKER comments. Once you select a new clip, the comments go POOF! Gone.
I just cut a 10 minute dialogue short with merged clips, and I can't think of a single time I knocked audio out of sync. But I was prudent in my technique.
If you need the functionality, 1) file a bug report and 2) use the PluralEyes method.

No three point edit with merged clips in Premiere Pro CC 7.2?

Hello Premiere Folk,
I've recently, as of last night, updated to Premiere Pro CC 7.2. I'm currently cutting a feature using merged 5K red raw clips. We were expereicning some weird things but were able to work around them. The update fixed to major problems we were having;
1. Bloating projects going from 808kb to 5mb for no reason.
2. Not being able to perform a match frame on merged clips.
The update fixed these issues, but don't throw on your party hats just yet. Within this update a fuction CRUCIAL to any editor has been taken away after you've performed a merged clip function... THE EDIT! Any time I make an in and out point in my source with a merged clip and an in and out in my timeline and try to do an insert edit via a hotkey, it just edits the entire clip in the timeline starting with a radnom in point! I was able to set an in and out in my source and just edit into the timeline but even that function has been taken away. Adobe please fix this! Yes the match frame with a merged clip works but dont take away editing basics!

This bug is NOT FULLY FIXED. I'm on a tight deadline so i'm not looking very hard online to see if i'm alone - so please forgive me for just posting here...
I'm using CC7.2.1 it's 1/21... very grateful that match frame FINALLY works on merged clips, but, again, this insert/overwrite bug is only PARTIALLY FIXED.
Insert/overwrite with merged clips on 3-point edit now works, but ONLY when cutting in BOTH merged video+audio... if you're just trying to cut in the audio from a merged clip using a 3-point/4-point edit via hotkey, it's a no-go.
I, for example, needed to re-cut in audio under some video with effects on it. So, I unpatched the video source completely and patched source audio tracks 1-4 to the appropriate sequence tracks. Upon hitting insert or overwrite multiple times, nothing responds. The only way to cut anything in from the source (merged clip) was to patch the source video back into the timeline on an unused video track, then cut ALL the tracks from the source in, I then had to delete the video track re-link the now free audio to the original video. Not a big deal, but annoying enough & waste of precious time on tight deadline.
So, yeah, I have a workaround but is still not appropriate to have a core function not work properly. Especially when I'm working with a very complicated timeline.
That said, thanks for keeping on top of our gripes, Mark.

Trimming tool problems with merged clips

I'm trying to edit a filmstyle sequence with merged clips (created video and audio synched, then merged into new clips). This works fine, except when I try to trim edits in the sequence - the trim tool works, but the picture in the left and right trim windows jump to different parts of the clips being trimmed, and do not show the correct frames being trimmed. The trim tool works fine when used with unmerged clips, but somehow can't seem to work with the synched up clips
The footage being edited was shot on RED and is in pro rez 4:4:4 format.
Has anyone else experienced this problem? Is this a bug, or is there a way around this? Thanks for any pointers...

Help with merged clip decision for a short film

Greetings and thanks in advance for any perspective you can offer.
I've begun to edit a short film (10 minutes) that has 3 hours of dailies. The clips are all merged clips, created with dual system audio and synced with Plural Eyes 3.
However, before setting to what's sure to be months of work, I wonder if there was a better workflow. Bear with me. To begin with, marker comments do not stick with merged clips. As soon as you select another clip - poof! They're gone. And there are other limitations that may or may not affect me down the road. I guess I'm saying I'm not completely sure what I might want or need to do at some point, but I'm concerned that I'll be limited for using merged clips.
I've realized I can use Plural Eyes to merge my clips and audio fully outside of Premiere CC. Those clips, once imported, retain marker comments and suffer no other "unique" limitations.
It will be a massive undertaking to resync, re-import, and retag and organize everything - but perhaps in the long haul this is prudent? Or not?
I'm cutting with Prores 422 at full size 4K, so replacing media isn't a concern. Anything else I should be worried about? There's always a chance I'll use a 3rd party to color-correct with a DaVinci.
Thanks again.

I shoot for about -6dB, with no peaks above 0dB.
Sounds like you have a very weak signal. I'd set away from PrPro and handle this in SB, or Audition. Listen carefully with a good pair of noise-canceling headphones first, and then test on monitors.
Are you working in mono, stereo or 5.1 SS?
Good luck,
Hunt

Trim mode with merged clips

I'm cutting a feature film on FCP 5.0.4 editing 23.98 NTSC DVCAM. The audio was recorded on a hard disk recorder with independent timecode and the clips were merged using slates.
If I enter trim mode by double clicking on the video track (with the purpose of trimming only the video track) and change the duration by clicking on the +/-1 or 5 frame buttons, the picture will suddenly jump by 5 or 6 seconds and the white "out shift" or "in shift" numbers will jump 5 or 6 seconds as well. Dynamic trimming has the same problem.
However, the actual edit made is correct, it's just impossible to see what frame I'm on without playing it back or getting out of trim mode. If I trim the audio and video tracks together then everything works as it should.
Has anyone seen this problem before? Know how to fix it? I couldn't find anything in the archives.

P2 workflow with merged clips

Hi,
I'm working on a documentary with approximately 50 hours of material, DVCPro HD 1080p25. There are several shooting-periods and we're already working on it.
I logged and transfered the media to separate shooting-day bins and divided it by Firestore and Card number, eg 200801_16FS1.
Audio is recorded on HD and there is an external TC generator on the camera (HVX-200) making a audio signal with TC, linked to the audio recorder (Cantar).
With Timetools 1.0 (updated it to 1.1 but it didn't work, Leopard maybe?) I overwrite the video TC and I manually merge the clips by TC.
Sorry for the long introduction.
Now the problem....
Because of 2 Firestore and 3 P2 folder each day I made a day-sequence of all the material as an overview (separate days). Also the audio runs longer so I had to combine clips on the day-sequence.
Now if I work with the day-sequence I have to scroll the sequence, find the material, match frame it, adjust the I and O point an patch the audio (because I don't want to use the first 4 tracks of camera audio). Before I can insert or overwrite in my working-sequence.
Or..
Scroll the sequence, find the material, set I-O, cut I-O, copy, and paste it in the working-sequence.
If I want to go back to the day-sequence from the working-sequence I have to match frame (I see the merge clip), reveal in browser, read out the bin name, go to the day-sequence.
This all seems a little bit too complex, and I've the feeling it can go a lot quicker.
So I'm open for all suggestions.
Thanks a million,
Tim

1) what if i'm working in 720p, does a 720 capture change things?
WHy would it? If you are working in 720p, then capturing 720p only makes sense. I don't understand what you mean.
2) what do you use your mxo2 for?
Capture of tape formats...output of tape formats...broadcast monitoring...direct capture from a camera if in a studio type situation.
3) the thing that frustrates me about p2 capture is that the duet card is unreliable
Duel... but true. And under Snow Leopard, incompatible. This is why I kept my Powerbook G4.
firewire to hd is slowwww,
Faster than real time, actually. No matter if you shot 1080 or 720...injesting is faster than real time. Yes, you have to back up the files, THEN import. But that is the way with ANY tapeless format.
and p2mobile/gear is so ** expensiv
I hear ya. Look for a used Powerbook on eBay, or look for a PC laptop with PCMCIA connection. FAR cheaper.
I was hoping by going SDI out would give me another option. i
For capture...sure. But still back up those cards! Those are your master tapes.
OH, wait, you said FREEMAN. Sorry

Sync problem with Merge Clips options in PP CC

Hello
First post in the Adobe Communities! I'm glad to be a port of it
I'm editing a short film and I've started using the Merge Clips option to do the syncing of image and sound, together with the "In Points" option as the Synchronize Point. When I sync material I like it to be exact and perfect, therefor I use the Audio Time Units option to do so, to insert my in-points, but when I Merge Clips the result isn't as exact as I told it to be, the audio clips are slightly out of sync, very slightly but annoyingly, and it seems to ignore my workflow, or adjust it self or something. I was wondering if the Merge Clips option supports when you use Audio Time Units option to set the in-points for syncing, or if there is any other option or work-around to get the syncing perfect. OR, is it suppose to be like this when syncing? I hope not. I'm not sure but I think I hear an echo effect in the merged clip as well, very minimal though.
The screenshots are zoomed in on with the "Show Audio Time Limits" option on.
I want it to be like this...
...But it end up like this when I Merge Clips
Thanks for reading, hoping someone can help me out!
Best Regards,
Daniel

Thanks, I suppose I can start batch-converting my mjpg movies before importing them inte PE7, if that would make this problem disappear. I'll try that (I have FormatFactory installed, but VirtualDub seems like a nice tool if that is better), although that would make the process a bit more long-winded...
Regarding GSPOT info on a file that works and one doesn't, there are typically no difference between them (except length and content, of course). In fact, as I mentioned above, the same movie did not work until I did some reinstalling, clearing caches etc. Then the same movie suddenly worked OK again.
I attach the GSPOT info on that file.
(I never had this problem on my older XP system that run PE2...).
I will try converting to see if the problem disappears.
Thanks!

Match-Frame with merged clip doesn't work

I have a merged clip forged from one video clip (with four channels of audio) and two audio clips, so the resulting merged clip has six channels of audio.
Merged via in-point, everything's in synch, fine.
Edit the merged clip into timeline.
Match frame.
Problem:
It matches to a clip with the same name as my merged clip... but it's not my merged clip because it's only got the four audio channels from my video source clip.
I've tried different clips, tried linked or unlinked, same result.
To boot, if in the timeline I select only audio channel #5 (which was from one of the audio source clips) and match-frame, it matches to the same pseduo-master clip, but, is several frames or seconds off.
Ideas anyone?
thanks!

Interesting... if I make a merged clip and name it "Apple" then place it in the timeline, the timeline clip is also named Apple. If I then in the browser change the clip's name to "Brother" and put it again in the timeline, it puts in a clip called "Apple"; and the first clip in the timeline is also still called Apple. But if I delete the Apple clips from timeline, and now put in Brother clip, it puts in a clip called Brother..... as if it's not updating the name-change. So that's weird.
But, none of the name-changing affects the match-fame problem; it still fails.

Disturbed Audio with long clips and speed changes.

Hello,
I experienced a strange problem in FinalCut Pro (v 6 and 7).
-I capture a clip with a Blackmagic Decklink or a DVS Pronto as Uncompressed Quicktime, 720p50 via HD-SDI with embedded audio. The clip is about 10 minutes long.
-I speed down the clip at 36% by changing the clip's speed in the sequence.
When I render the audio track, I get completely distorted audio after some minutes until the clip's end.
The problem doesn't seem to occur when I put the clip in a sequence and nest that sequence into a second one and change the nested sequence's speed.
Is that a known bug? Did anyone out there experience the same problem? Is there any technical explanation and solution?

Both Picture Safe and Title Safe are guidelines. They were developed to ensure that titles and pictures placed within these guides would be viewable on most televisions.
In the same way that no two tv's will look the same with regard to colour, there can also be a great difference in overall picture placement on the screen. Keeping titles within the safe area will help ensure that even the most poorly calibrated set will still show the entire title.
You can't convert the MP4s because you do not own the right to use them.
As for the MP3's, time to do some work and look it up. The Search function here is a great resource.

No audio with avchd clips

Hi,
My video camera produces .mts files - avchd.
Wanting a good editor I downloaded a Trial version of Premiere Pro CC , BUT no matter
what I tried - including many suggestions from on line users- could not get audio with any
of my clips. Prelude was able to "ingest" the clips with audio BUT whenever I exported them to PP
they were unrecognizable by PP.
Cannot seem to get any definite answer from any authority in Adobe. Is this problem insoluble?
I would like to buy into PP CC but not if it cannot handle the files my Panasonic camcorder produces
whats the point? Also transcoding .mts files into another format ( which works with PP ! ) reduces the
quality and is not acceptable.
Anybody know the answer?
( Win 7 (64) ; Intel i7 920 )

Audio is at times the bane of the video editing side of things. There's been holy Hades raised here at times over the way PrPro does ... or really, doesn't ... handle "extended" audio channels as they would seem to be logically best handled. And the comments that some other programs handle X part of this easier. At which point there's oft a comment that yea, that be the case but that other program handles Y part of the audio process like a truly crashed turkey.
It seems to me the point is that perhaps none of the editing apps are where they should be for treating the audio part as seriously as the video. There've been comments and blogs from Adobe that this is why they have Audition, to handle all the audio stuff. But to many of us the way that Audition & PrPro work is not as "transparent" as we need it to be. Audition normally overwrites original files unless you purposely save-as. PrPro never over-writes original footage files. A few people have been caught by trying something in Audition ... without save-as-ing, and unfortunately without proper back-up, and ruined their audio. With no way back. Unfortunate, but in the differences in the two program's methodology, this is bound to happen at some time to almost anyone. "You should have known what you were doing before you did it" ... yea, true ... but in a hurry under deadlines, well ... baaaad things happen. Especially when one gets used to a HUGE "feature" of the Adobe video apps: non-destructive editing. Oh, sorry, Audition is a wee bit different. People need to know that!
And ... yea, setting up PrPro for 5.1 or 7.1 is entirely possible ... IF you know exactly what to set in preferences (which is not explained clearly for those who aren't already knowledgeable) AND how to move things about on your tracks in a sequence. So some of the experienced people feel it's not THAT hard a deal ... deal with it and move on. For noobs to the scheme of this, it can be completely un-penetrable.
Hope you get this nailed ... and there are some wonderful people around here that know those settings and when they do pop in can give so much help ...

Edit attached audio with movie clip

I made a project by combining movie from one camera (with audio muted), plus audio only from a second camera as an attached audio track. The two cameras were recording the same scene, so the (better quality) attached audio can be put in sync with the video from the other camera.
How then can I delete a section of the video AND the corresponding section from the attached audio channel, so the remaining audio remains in sync?
"Split Clip" splits the movie but not the attached audio. Is there a way round this?

Sorry I never posted back about this. I got sidetracked with putting together a different vacation video and forgot all about it.
Anyway, what I posted before totally worked. I exported the movie as an mp4 at full quality (I'm not sure if there was any loss of quality, as the footage I started with was not very high resolution. There was no discernible loss of quality, though). Then I took that newly created mp4 and re-imported it into iMovie.
iMovie treated the audio that had previously been pinned as embedded audio, so now when I cut a clip, it cuts the audio with it.
Kind of a pain to do the extra step (especially since importing all of my raw, unedited footage and re-importing it took a while, but working with it now is soooo much easier.
Hope this helps anyone who may stumble onto this thread in the future.

How can I use all tracks from multi-channel source audio with Multicam clips?

I cannot figure this out. Working in Premiere I'm prepping for a 2 camera show, with typically 4 to 6 track dual-system audio recorded by the sound guy. I can sync, and make multicam clips any number of ways–whether sync by timecode, sync by audio, or eyeballing–but whenever I edit using the MC clip, Premiere mixes down all the audio channels into a stereo single track, and I cannot pick and choose which audio track from the original to use. With 2-5 people mic'd on lavs, I need to be able to choose which audio is either cut in or heard at any given shot.
Is there any way to have control in multicam clips over which track of audio gets edited into the timeline, or even: that all tracks of audio get cut in? It's very important for the editors to be able to see waveform (which also disappears for some reason in the mixdown) and pick and choose which audio is heard?
I'm sure this might be a simple fix, but I cannot get my head around it for workflow purposes for my assistant editors. We need to use multicam, but this audio thing is driving all of us crazy. None of us can figure out how to have a multicam clip and use it with control over what audio is cut in.

True, but what I need to be able to do is have my multicam sequence in the source monitor, and cut into my working sequence with either just the audio I need from the sound guy's multi-channel WAV, OR cut in all the sound and from then I can just enable or disable what I need or don't need. But also be able to match back to the Multicam source from my working sequence.
I don't want to have to open the synced sequence, and razor blade the things I need and have to copy and paste into my working sequence in order to have the full spectrum of my multi-channel mono lav WAV files...with their waveforms visible.
Essentially, I want my Multicam clips to load in the source monitor, and the ability to cut them into the working sequence without it mixing down the audio into a single track with no visible waveform–which is what it is doing currently. Can I choose to edit in either ALL of the tracks of the WAV file along with the camera shot I want, or control which audio gets cut in?
