converting to sd

Posted by Deepak Verma on March 14, 2008 at 12:20 pm

I am planning to buy and pmw-ex1. but at the moment struggling with a question

the inherent format for the camera is 16:9 where as my requirement is SD for broadcast purpose in India and wide screen for other purpose

i have read that it is possible to downcovert the footage in SD.
as i have seen with some other downconversions that they keep the aspect ratio same – while coverting the footage. how is it possible to covert HD to SD so that it becomes real SD – mean i do want black bands above and below.
has anybody done it that way?
can they share a clip or two?

will there be a quality loss?

The way I see it is you will either have letter boxed images-bands at top and bottom, or center punched- no bands at top or bottom, but the side are cropped.
Center punching fills up an SD screen completely.
If you shoot with center punching in mind it should not present a problem.
You also have the option of panning around within the picture.

thanks Kevin
what will be the best format to shoot if i shoot keeping center punching in mind so that it comes automatically vertically and i crop sides (to the bare mi minimum possible)
as the final output is going to be on DIGIbeta for telecast

second will in involve redering in FCP – i have 5.1.4 and soon planning to migrate to studio 2

what kind of losses i should keep in mind

I have only been shooting in 1080 formats.
The tricky part is setting up FCP.
I’ve been editing in an EX-1 timeline using the Apple Pro Res Codec for rendering. Then copying everything and dropping onto a DV timeline for DVCAM recording.

You will need FCP Studio 2 and all the upgrades. Quicktime etc.

Kevin,

[Kevin Jones] “I’ve been editing in an EX-1 timeline using the Apple Pro Res Codec for rendering. Then copying everything and dropping onto a DV timeline for DVCAM recording.”

I don’t know FCP at all, but may need to interface with it sometime. Can I assume that Deepak should follow your methodology up to but not including dropping into a DV timeline and rather drop into a 601 uncompressed timeline, render and play out to his D-Beta deck?
