Adding CG effects to HVX shots

I am still waiting, like many of you, for my HVX. We are making a short film that will require CG shots out of Maya, and I am looking for some advice. I would like to get started on some of the CG work, but not have to re-render after I get the HVX.

Mainly we will be doing DVD output, but I will keep a HD version on a hard drive for future use. I think I would like to shoot using one of the 720p24 modes, going for the best filmlook at 720.

My question is, what format should I render my CG clips so they will match the framerate of the HVX as best as possible. I generally render full TGA frames when I do CG, but what should I set the framerate to ? 24, then I get 24 distinct frames, or would I need to render some version of 29.97, because that is what the HVX is really capturing?
 
The HVX like the DVX can record 24 progressive frames. Do your CG at 24fps too. Finally, encode your DVD at 24fps. IF you have to lay to tape, you would add 3:2 pulldown to make it 29.97.
 
Thanks for the quick response.

So, this would equate to using the HVX in 720p24 mode? I also see the new 720pn24 mode, are you aware of the benefits/downfalls to using that mode?

And if i use the standard 720p24 mode, do I need to use Cinema Tools to remove any pulldown, or does that transfer into Final Cut as actual 24 frames?

Thanks in advance.
 
720p24 mode will add 3:2 pulldown which makes it 29.97. 720pN24 mode will record only 24 frames to a P2 card.
 
I'm a novice so I'm a bit lost on this. If I shoot onto the P2 card in the 720P24 setting... then load the footage into FCP HD, at what point does the pulldown come? Can I output onto DVD and have it be viewable on a SD TV set? In the 1080i mode can I also do a pulldown in FCP to view it on a standard TV?

If you shoot 720P24, this adds the 3:2 pulldown in the camera. To make the DVD, you can to output a Mpeg file using something like Compressor where it will downsize the footage for SD. Same goes for 1080 footage. Keep in mind that you can encode DVDs with 24P footage. If the DVD player is progressive scan and your TV is also progressive, it will play at true 24P. If you have an interlaced TV, the DVD will add 3:2 pulldown on the fly. I generally prefer working in true 24p because it takes up less space on your hardrive and looks better on Progressive DVD players and TVs.
 
the main benefit of the 720pN24 mode is that only 24 frames are recorded to the p2 media, rather than the pull-down frames too. so you save a substantial amount of space and let your software and/or dvd player deal with pulldown later.

You might also be able to get away with rendering your CG clips at a lower resolution than 1280x720. The images you will get from the HVX will not match the crisp full res renderings you would get from your CG program. You will have to do some testing, of course, but depending on the complexity of your animation you could save hours, if not days of rendering.:)
