Question

Avid to Adobe Premiere MultiCamera Issues

Hi,


We have a split system of Avid & Premiere - down to cost unfortunately as one or the other would certainly be easier.

Due to our main system codec (ProRes) usual media manage within Premiere isn't 100%

We have been trying the option of Avid to Premiere which has mixed results with multicamera sequences

Also Text titles come through all over the place.

So the workflow would be

1. consolidate the sequence to an external drive and export visions and audio AAF from this sequence.

2. Import the AAF in Premiere and link the consolidated MXF files made from the Avid consolidate.

The problem is we get an error relating to the audio being from so many audio channels when only 1 has been used in the sequence.

The workaround was to export a wav for that layer in avid.

Is there anything which might help or is this a problem which won't be fixed?!

Cheers

Well arky if it made sense that would be one thing. You aren't adequately explaining why you would do such a thing. A cost thing surrounding which one to work on would be one NLE rather than 2. That is just simple math. What I am trying to say is you need to explain "the cost thing" better. If you are trying to figure how to properly media manage modilefalck has started you down the path to roll your sleeves up and finish the task like professional editors do on the daily. You won't be able to just click a button and it is done. If you think you will find that in Avid, think again. Any NLE is going to have these inherent issues.

Your more realistic workflow:

  1. Duplicate your master sequence to prepare it for media managing.
  2. Flatten all multicams, dynamic links, and any other nested sequences.
  3. Export all clips with speed changes and bring them back in to your master sequence that will be media managed.
  4. Flatten the rest of the timeline to make it look tidy(extra credit and less taxing for exports)

You will run into more issues and you will have to add to the list but media managing is not a one button solution.

The Project Manager in Premiere Pro has a serious bug (or design flaw), that makes it hard to be useful even with Premiere, let alone interchangine sequences with Avid.

I wrote earlier....

"The most common cause is having the audio channel layout of the source media file not match the one specified in the transcode preset.

The transcode preset needs to have a "match source" button (but it does not!) as it's not practical in the real world to expect all source media to have identcal audio channel layouts."

Basically I have taken to consolidating video only sequences, and exporting an OMF with handles for the audio.  I open the OMF in Audition, and export an XML.  import the XML into the consolidated project in Premiere and paste the audio into the sequence.

This is the only way I have reliably found to consolidate sequences without the audio channel error causing entire media files to be copied.  And even this does not work 100 percent of the time.

Adobe's Project Manager is a mess. 

Media managment in Avid works beautifully.

I am still not entirely sure why or even when in your workflow you would attempt to conform into another NLE but unless you are going to turnover to color grading or vfx what is the point of all the hassle? Pick one NLE or the other.

Really helpful that! If there was an option of just one NLE I'd be doing that unfortunately there isn't.

As the post above states we're having issues with Premieres ability to handle media manages hence the need to edit on Avid and translate.

If there was issues we'd certainly stay within Premiere world but that's why I'm here.

Nope.  Avid and Adobe have completely different approaches to multicam and media management.

i would not attempt having the two systems interchanging with anything but the most basic of sequences. 

sorry, not the answer you want to hear.  You'll spend so much time trying to make this work, that you really won't be saving any money with all the lost productivity.

Yes its a shame really as it nearly does work....

The issue we have is we need to media manage under tight deadlines and have issues with Adobes results.

We're finding the below happens....

Collecting - bringing most over

Consolidate & Transcode - "Transcode failure. Unable to match audio channels file was copied"

Again is this a multicam issue?

In some cases the files needed to be copied can be upwards of 2/3 hours so would mean a big copy at the other end.

Multicam is but one of the things that will cause transcode failure.

Another is source side LUTS or Lumetri Effects (not ones added in a sequence).  Some of these are added automaticall, and you may not be aware they are there.

Another is speed changes on subclips.

Amother is keyframed speed changes.

The most common cause is having the audio channel layout of the source media file not match the one specified in the transcode preset.

The transcode preset needs to have a "match source" button as it's not practical in the real world to expect all source media to have identcal audio channel layouts.

***For multicam to be trimmed, you need to flatten the multicam clips before attempting to use Project Manager, otherwise it will use the entire media file for all clips in the multicam group.  This will not work 100 percent of the time, but most of the time.
