Workflow for 23.976 source to 29.97 interlaced for broadcast delivery
Workflow for 23.976 source to 29.97 interlaced for broadcast delivery

I know this question has been asked before, but I'm still not totally clear on the best method.

I have a 1920x1080 23.976 progressive sequence using footage that is also 23.976 progressive. Because I assume progressive will be needed eventually for online use, I have everything in a 23.976 progressive timeline.

For broadcast I need to deliver 1920x1080 29.97 interlaced.

What's going to be my best option for best delivery?
1. Export the 23.976 progressive timeline directly to a 29.976 interlaced deliverable.
2. Export a 23.976 progressive Master (DNxHD) that I then encode (via Media Encoder) to 29.97 interlaced.
3. Since I still have the sequence, I could change the sequence to 29.976, then queue in Media Encoder where I make the change from Interlaced to Progressive. This way it wouldn't be two exports- but would that matter?

It seems the general consensus is option 2. Is there any advantage to do it any other way? I read about 3:2 pulldown when going from 24 to 29- Does PrPro do this automatically or do I select it (I see the option on only some of the export formats)?

Thank you,

Stephen

Don't forget that you will not only have to deliver the show as 29.97 Interlaced but it will also likely need to be 29.97 Drop Frame. This poses a cut length issue. As an example a show that must be delivered as 45;50;00 with say 5 x 10 second blacks will need to be cut to 45:47:06 at 23.976 with 5 x 10 second blacks.

I wish I could help you more on this but I always use Avid to do these conversions and so I'm not that familiar with how it's done in PP.

I have always been advised to run the 23.976 Progressive Master through After Effects, being told it was the best method for this conversion, using the last option of the 5 listed under 3:2 (I believe WSSWW). HOWEVER, the last time I converted I found it just as good and more efficient to duplicate the sequence in PPro, change the settings and export from there.
