HD to DVD render settings

[John Rofrano]

Yup, those are good settings for a standard NTSC Widescreen DVD. Your other option would be to render 24p to keep the footage progressive but you have to be careful that it doesn’t look jerky at 24p if you didn’t shoot with 24p in mind.

Thanks for the info. Which do you think would look the best over all?
I looking for as sharp of a picture as possible.

…If I shoot progressive, I keep progressive all my settings and I’ve always have rendered progressive even in DVD arch 29.97 template… and seems to obtain very good results for DVD… is there any difference if you render interlaced or progressive ?? …I’m taking about shooting 1080 or 720 30p for producing SD-DVDs (not 24p)….

kind regards

I would try a sample render to see which is sharper. While the 24p will keep everything progressive, it will change the frame rate which will blend frames to fit 30p into 24p so using 60i may actually produce an overall better picture but you be the judge.

There is no progressive video on a DVD that is not 24p. You may be changing the 29.97 template to progressive but that it not what gets placed on the DVD. DVD players support 60i, 50i, & 24p. That’s it. Those are the only formats that are supported by the DVD spec and thus by DVD players.

Now you may have a DVD player that supports some non-standard formats… heck there are even DVD players that support DivX but that is NOT part of the “official” DVD spec and is specific to just that player. At that point it’s not a “DVD” anymore… it’s some hybrid disc format.

There is no different in the end. What gets placed on the DVD is interlaced footage. If you render progressive, then it will get re-rendered so I guess the only difference is quality based on how many times you re-render your footage. If you only want to render once, then use 60i, 50i, or 24p.

…. DVD arch never re-renders my “progressive” rendered video footage from Vegas… in fact, the prepare time for a interlaced rendered or “progressive” rendered DVD is the same, for the same video…. for some reason (maybe wrong) I’ve been very happy staying all the way “progressive” if I shoot that way…. and all the DVDs I’ve made are 100% playable on every DVD player I’ve found without a problem…. there has to be something between Vegas & DVDarch that makes no difference if you render interlaced or progressive.. could it be ??

thanks…. good luck

Has anyone determined the best HD settings to shoot with if you are primarily delivering a SD DVD? The image will be rescaled to 720×480.
Thanks.

If I knew that I was delivering SD DVD then I would shoot 60i just like SD DVD. I don’t have a camera that shoots 30p so I can’t tell you what 30p looks like when converted to 60i but you should just do a few render tests and see what’s acceptable to your eyes.

Well… I did a test and you are correct. DVD Architect did not seem to need to re-render 30p. I don’t have any tools that will tell me what format was actually in the VOB file but if it works… I guess it works (but it’s not in the DVD spec).

I have been shooting 30p and rendering to DVD as progressive without issues. I use Vegas 8 Pro and DVD-lab. I’ll try some test renders and see what looks better.

One thing about progressive. I had a client complain about the motion blur. Another thing, they think the DVD should look better than SD because it was shot on HD. Nope.
