Yet Another Mixing Frame Rates Question

I shot a wedding last week that was quite unique. Since the bride was a professional dancer and the groom a screenwrite, it seemed only natural for the ceremony itself to be a stage production of the bride and grooms courtship.

Anyway, I shot all the rehearsal, getting ready, group photos, and reception footage, in 60i, and shot the actual production at 24p.

Here's the scenario: I plan to do a 29.97 interlaced project for all footage but the production. I then will edit the production in a 24p project. I plan to deinterlace the 60i footage and export everything (60i and 24p) at 29.97 progressive then bring into encore to make the DVD.

Ok, does anyone see any issues here. If so, how would you do it differently?

Thx-
 
Are the ceremony (production) and the 60i stuff going to be separate files, or will it be one continuous program?

Why are you going to deinterlace the 60i stuff if you're planning a 29.97 DVD? I assume you shot it as 60i instead of 30p because you want the "reality" look, right? You'll lose that if you deinterlace it, or at least a lot of it. You'll lose half your motion samples (if you deinterlace to 30p) and up to half your vertical resolution. It won't look "real" anymore.

If you're planning the ceremony to be separate from the rest, then you should edit as 24p and output as 24p -- a DVD can have files of separate frame rates, so you can have a 24p file and a 60i (29.97) file on the same disc, and they'll both be in their native timebases.

If you're planning to have it be one continuous program, I'd do all the 24p editing at 24p, all the 60i editing at 60i, and then bring the 24p sequence into the 60i sequence for final export (to NTSC). That way, it won't matter if you shot 24p standard or 24pA.
 
They are going to be separate files.
In regards to the deinterlacing, I wasn't sure if there would be an issue with the DVD and having both interlaced and progressive footage together. From your comments, sounds like there won't be an issue.

But this leads me to my next question: When transcoding in Encore, then do I choose a progressive setting or a standard NTSC setting given I have both on the DVD?

One other thing: I probably won't, but should I choose your last scenario, do I simply import the sequence as an asset and then lay on the timeline or do I export it as an AVI and bring it in. Also, would I deinterlace the 24p footage in the 60I timeline?

Thx

I will have to look at that; I haven't used Encore all that much, but every other DVD authoring program I've used doesn't have a general setting for the DVD as a whole; they all simply take the files as they are and put them on the DVD.

Were you planning to export files (MPEG) and bring them into Encore, or to bring the Premiere sequences into Encore and have Encore encode them? I would tend more toward doing the MPEG encode yourself, but again, I'll take a look at it.

You can do either (assuming you're using CS4 and can have Sequences of separate properties), but I'd nest the Sequences rather than render an AVI, saving you a compression step. I would only look at exporting an AVI if the nesting isn't working properly for some reason.

Also, would I deinterlace the 24p footage in the 60I timeline?

No. Never put a deinterlace filter on 24p footage -- ever. But it wouldn't be necessary for any reason anyway -- if you're cutting 24p footage in a 24p Sequence, it's progressive. And bringing that Sequence into a 60i Sequence means pulldown must be re-inserted, so you wouldn't want to try to act against that in the first place.
 
First, let me say I'm still on CS2.

I will have to look at that; I haven't used Encore all that much, but every other DVD authoring program I've used doesn't have a general setting for the DVD as a whole; they all simply take the files as they are and put them on the DVD.

That was a total brain fart on my behalf. Indeed, Encore has the ability to associate a transcode setting for each clip.

By no stretch of the imagination am I a DVD aficionado. What I typically have done in the past is export my project as an AVI then stick it into Encore. As well, CS2 offers MPEG 1 and MPEG 2. I assume MPEG2 would be the format to use should I do this in Premiere. BTW- To my knowledge, sequences cannot be imported into Encore in CS2.


Thanks
 
OK, looks to be pretty simple, then -- edit the 24p stuff in a 24p sequence, and then export a 24p MPEG-2 for DVD (the Premiere/Encore manual should tell you exactly what you need to do for it to remain 24p for DVD).

For the 60i stuff, edit in an NTSC sequence and export an NTSC MPEG-2 for DVD.

DVD compliance means having a bitrate between 6500000 and about 8000000, and they're pretty much always variable. But there should be presets for that.
