24p help

[Tony Birkholz]

first, do you have to convert tapes to DVcam? second, it doesn’t matter how you digitize now it will not effect the online and use 29.97 throughout. recommend using a sony S2000 deck.

First off I am not a fan of the off-lining in SD any longer. The compressed codec for HD have made the down conversion process a no-brainier. Using DVCPROHD compressed 1080 files make for a terrific offline and you are still looking at a progressive image not the interlace of SD content. it also means that you will not have to build graphics twice. files compressed in this manner require drives to only playback at about 15mgs a second – easily handled by sata or FW800 arrays.

Second 24p HDCam is not 29.97 or 60i . Sony uses what are called progressive segmented frames – PSF – the camera captures the video as 2 separate fields/ frames then recombines them back into a single (sort of) frame. This also means that it will need to record / playback 48 progressive segmented frames / fields when playing out to a monitor.

Lastly – hire someone– one cannot honestly think that they will be able to handle all of the pitfalls in in HD /24p project if you have never done either, the Data, hardware, output, etc are fairly complicated for the uninitiated, Contrary to what apple has told people working in HD in not Plug and Play

AND did I mention that it requires 3rd party hardware to work with 1080 24psf files in FCP? It is not a native ( default) format in FCP and is currently handled only by PCI products such as the AJA’s Kona2 and others.

That’s a huge piece of advice. I’ve been doing testing and researching for an HD project since November 2004 and we just started delivering the masters last week. What I learned is that there is just not enough information about there about HD and there is NO standardized HD workflow. Each situation requires a lot of thought, research and testing in order to ensure that your project will come off correctly.

Where can I learn more about the difference between “FPS” and “PSF”. If not too much to ask, can you explain it further here? I’m confused.

FPS is Frames Per Second – or the number of frames that you will need to process for each second of content

PSF is Progressive Segmented Fields – The SONY process for creating 24 frame content within a system meant to handle Interlaced fields instead of progressive frames. The sony process is to capture 2 frames offset ( or 48 frames a second) in time and “re-bundle’ them back into a single progressive frame. This is somewhat akin to what the Nattress filters do to achieve a film look — but the timing of the 2 fields ( in HDCAM) are closer together than the process when done in the interlaced world.
