Re: [Avid-L2] Network Says Cut Native (24) and Deliver Broadcast (30 or 60)

 


In this case, I would finish in 23.976p, video mixdown the result, open the mixdown in a 59.94i project. Main reason: you should end up with constant pulldown cadence this way. If you convert your 23.976p sequence, each clip will be treated separately, and therefore with a new cadence from the start of each clip on the timeline. Plus, you will run into issues like matte keys not converting.

If you have rolling/crawling end credits, you might be required to add those in the 59.94i project.

Numbers have been rounded so really we're talking 23.976, etc.
Our contact at the network has told us that despite the specifics on the network spec sheet, which call for "…conversion of the finished master with an external, high-quality frame rate device converted and properly timed to 59.94i," we can do an Avid conversion.
But how? 
Do I simply open the sequence in a 59.94i project, render and export? This is the process I went through; does this make sense?:

  1. Cut a (native) 23.976p sequence in a 23.976 project - Project 24
  2. Created a new 59.94i project - Project 60
  3. Opened final sequence bin from Project 24
  4. Loaded sequence in record monitor. Got this message: "This sequence frame rate does not match the project frame rate. Do you want to load a copy of this sequence that has been modified to match the project's play rate?"
  5. I chose 'Yes.'
  6. Got this message: "Could not change the format of sequence [Sequence Name]. This sequence contains imported Matte Keys that must be mixed down. Please modify this sequence while in a project that matches the sequence's native project type."
  7. I then returned to Project 24 and removed the imported matte keys.
  8. Back in Project 60 I put the now matteless sequence in the record monitor and rendered all.

    Is this now a 59.94i sequence or at least the best I can do in Media Composer? And what's the best work flow to get the matte keys back in? 


    Thanks,
