Depending on which version of MC...my safe bet is to complete the show in 1080p, do a mixdown, create a 1080i project and bring the mixdown in. Put it in a timeline and re-export as 1080i.
I do this because changing frame rates of a sequence with keys and other effects is a mess, and the system will try and transcode all your keys to the new frame rate. Simpler to complete in 1080p, open the clip in a 1080i project and re-export.

Can't you just toggle the 1080P 29_97 project to 1080i 59.94? I've been very 23.976 centric for a while but I though that was possible. I would think if you toggle the project format to 1080I and refresh the sequence motion adapters it would do the same thing as opening it in a different project. Perhaps I'm missing something here.
If you material is truly 29.97P then converting it to I will not change the fact that both Psf/Progressive Fields come from the same moment in time. Converting to interlace will not change the fact that F1 and F2 are from the same moment in time.
I have had various hardware situations where a switch between progressive to interlace will cause a momentary glitch during playback. This was most obvious when outputting to tape and punching in with the wrong setup on a deck but I think I've seen file base shifts because of this.
The one thing I learns about a year or so ago is Nat Geo does not want 2:3 pulldown on the 29.97I delivery masters. They want 23.976 material to be transcoded to 2:2:2:4 cadence for delivery. They know it's more stutter but it makes the web encoding easier. The split frames of 2:3 material cause issues for them. Perhaps if it was a solid cadence of 2:3 they wouldn't have so many issues but I bet they were getting a lot of the Avid motion adapters where the 2:3 cadence restarted on every shot.

Open a new 1080i project. When you're in that 1080i project, do a File / Open Bin to the bin in the old 1080p project, and drag the old sequence into the new project. When you play it, MC will apply a real-time effect to make it 1080i. When you export the sequence from the 1080i project it will be rendered out as 1080i.

What is the best way to convert this master sequence? No tape involved. All content is digital and archival.ThanksLou
