Does anyone have experience rendering for HDV content 1440 x 1080? Which setting to use? I will do some camera match and compose using Premiere CS3, but never done it before. Any advise?

Thanks.

What do you mean by which setting? There’s an HDTV 1920x1080 preset built into max. Use that. If you mean outputting from premiere then I find that the best hdtv codec is H.264. The max bit rate will depend on where it’s going (hd-dvd, blue ray or broadcast or just playing off your computer).

I captured video from a Canon HD-1 which comes in HDV format 1440 x 1080. Premiere has a preset with this resolution, but if I render in MAX at 1920 x 1080 my image wont fit. I can render in MAX at 1440 x 1080 but still not experienced about pixel aspect ratio to use. My question is if anybody has experience and suggestion for this case.

By the way, what bitrate would you suggest for HD-DVD ?

Thanks for your reply.

I think the pixel aspect ratio for HDV is 1.3.

Let’s see: 1440 * 1.333… = ? ???? 

1920 !  That’s all there is to it:

If your vertical dimension is “correct” (1080), then to find P.A.R.:
(target resolution for square pixels) / (image resolution) = PAR
So, 1920 / 1440 = 1.333…

Hope it helps,
Jeff

oops, i misread your initial post. If your hdv footage is at an aspect ratio of 1.33 (like old school tv), then all you have to do is render out as 1440x1080 with an image aspect of 1.3333 and a pixel aspect of 1 and you should be set. If your hdv image is wide screen (aka, 16:9 = 1.7778) then you need to render out at 1440x1080 with an image aspect of 1.77778 and a pixel aspect of 1.3333 (which will effectively stretch your image to fit).

For the blueray and hd-dvd specs look here. But you shouldn’t really be worrying about that until authoring time. For now, work at the highest, uncompressed resolution you can (1440x1080) and compress when you write the disk.

this is often a confusion.
Consumer HDV cameras, and even most reasonably affordable pro cams, are actually 1440 with non square pixels. Kind of sucks really that this information wasn’t readily available when many people bought them. If something is posted as “full HD” I’d expect the pixels to be square and match without having to stretch. You lose a lot of information this way.

If your Premier project is 1440 then i’d render 1440 so you don’t lose any quality, and I’d also render uncompressed. No H.264. Not until final output, which I would assume is going to be a high def DVD. If not it’s probably a waste since most monitors don’t even have the pixels to display that info.

If you are doing things like camera matching in post I might consider using AfterEffects or combustion though.
