Premiere Pulls the Wrong Audio but the Correct Video

I understand that this issue occurs due to the fact that camera output files have the same name, I simply want to know when this issue will be addesed and fixed, having to rename every single camera file each time feels kind of ridiculous (given we sometimes have 4+ recordings in a day). I know it is probably not an easy fix given how long it has existed as a problem, but it would be really nice to get a fix for this as it would save a decent bit of time. I have noticed that it can be entirely fine in premiere, but once you export to media encoder and render it has pulled the wrong audio once again (just wanted to add this error as well). The basis for the fix seems like it would be to use the same system that is currently used to pull the video to pull the audio (I have yet to get the wrong video) 🙂

Correct answer David Arbor

I like David Arbor's theory, above.


Thanks for posting the details. This isn't a bug with Premiere, and as Neil said, it's a problem in lots of other software. This is a result of the irritating structure of AVCHD and any other format that automatically names the first clip of a new card as "00000." You need to speak with your boss and explain that this workflow is causing problems. I would never edit a sequence called "00000" or work with clips that haven't been renamed as you or the next person opening this project later will have no idea what the clips refer to.

 

Given that you name your exported files with very clear titles, I would strongly recommend you name your clips and sequences with those exact same names. Since you're already changing the name on file export, this should have no impact on your workflow if the sequence has the correct name to begin with. 

 

Again, this isn't a bug, this is just the result of having a bunch of clips with identical names. Imagine you have a stack of books with identical covers and the same number of pages but the page contents were all different. You can likely keep track of things in the moment, but you'd have no idea which one you were reading if you left the room and came back later. That might not be the perfect metaphor, but it's essentially what's happening.

I work for and teach pro colorists. Especially as these days many colorists are essentially "finishing artists" also, created the final deliverables for the client. This is a constant problem, and the 'fix' varies on the NLE in use.

 

And if you go to say the LGG forum, and look for threads on this, you'll get very direct comments about having a proper DIT on set who knows to rename all media like this to proper names ... typically a shoot/date/time sort of naming schema.

 

As if this is done right off, it saves everyone a TON of headaches.

Hi Niel, thanks for your reply, sadly there is a specific naming convention that my boss has told me we have to utilize so I cant change much, the folder structure is where we keep that infomation at the moment we use "Class_Name/Session_Date/Camera_A/(then here goes the structure created by the cannon camera)" 🙂

Totally understood.

 

In the way video post is typically structured, a lot of working processes are essentially fractured between barely connected services ... shooting doesn't have a real or good DIT, and the client's 'ingest' process is a temp or low-level employeer working from a script. And on through the process in two/three different companies/free-lance people working the project.

 

Or ... I've been told how fractured the process is in a large firm, with the various parts basically their own entity and not a lot of useful communication on actually setting up a smooth process. Which is a pain for everyone, but ... as everyone's overloaded as-is, no one wants to take the time to build a better process.

 

Even using something like adding a Reel name can help at times, but ... well, that's the extra step that The Boss may not consider part of the SOP ... and not approve.

 

Perhaps @Bruce Bullis or @Fergus H  might have an idea ...

Can you actually describe the problem and provide screenshots if those are applicable? You mention an issue in the post title, but the body implies that anyone reading this knows exactly what your issue is. Naming conflicts can be an issue in many pieces of software and if a file is linked just by the file name and not an internal ID then it's not unreasonable that two files with the exact same name could be swapped, even if you got everything working fine in Premiere.

 

Can you detail your workflow and provide more clear information about how to reproduce this issue?

    Yep I definitely can 🙂

    In the leftmost panel you can see the default naming convention that our Cannon C200 uses, each time the card is formatted it will start back at 00000.MTS when the next recording is started. The file automatically breaks and incriments the the file name by one each time approximately 11 minutes pass in one recording. In the middle panel you can see premiere (I have disabled the video of the presenter since I dont have permission to show them outside ASU classes). The way I import the video files to begin editing is I click on the project browser, press CTRL+I to open the import window, navigate to the 00000.MTS file, select it, then I click open. Premiere will then recognize the Cannon file structure and link the videos together irrespective of the number in one stream. Next back in premiere I right click on 00000.MTS and select "new sequence from clip". After that it starts generating the peak file for the audio, during this step it will choose to pull the incorrect audio fairly often. If it does not I complete editing the video and select the in and out points on the timeline. Next I press CTRL+M to open up the export menu, then I select "send to media encoder". In the third panel you can see Media Encoder, at this step I drag one of our presets onto the clip depending on what the video will be used for. Next I click on the output file column and place it in the correct folder utilizing the naming convention we have chosen. After that I click the play button and let it render, now when I look at the exported video it will occasionally have pulled the wrong audio despite it being correct in premiere. Renaming 00000.MTS and the following files will ensure that this never occurs but it takes a decent bit of extra time. Let me know if I can provide any additional information 🙂
