720/30p captures possible?
So I’ve always been capturing uncompressed, DVCPro and ProRes to 720p at 59.94 Hz. I know that there is no broadcast standard for 720p at 29.97 Hz. But, here’s the thing: I work in games, and most games are authored to be locked in at a render of 720p at 29.97 Hz and the console hardware just doubles up the frames to 59.94 Hz. So, I capture footage at 60 fps and work in a 30 fps sequence. It works out okay, I mean that way I’m seeing what my final output is since my output is 29.97 Hz. But there’s some huge problems; mainly, my source footage is taking up twice the footprint that it should. This is bad for both array space, and also it halves my disk performance. With a half rate sequence, I don’t have renders that are twice what they could be, but they are still longer than necessary since I’m taking an immediate performance hit on the real-time conversions of the source material’s 59.94 to the sequences 29.97. I could batch convert all source footage, but I’m often working with source footage that is dozens of individual captures consisting of dozens of minutes of footage, but I only need a small portion of that footage to work with; however, I’m also under tight constraints for turnaround, so even though I have an octa-core, I still don’t have the time to wrangle all captured footage for a session and batch convert to new source material, or sub-clip. Before FCP 7 came out, I was glad to see that it had “new alternate versions of ProRes to better suite different ranges of workflows” (paraphrase). But there’s still no capture setting for 720/30p in ProRes. Why can’t this be done (is there a hack)? Even something like a “pn” like the HVX uses to reinterpret data within a 59.94 Hz stream while actually only recording and storing 23.98 or 29.97; is there something like this that I can utilize?
