Performance Quality DVDs

[Daniel Ludwig]

Hi Hillary,
if your disk will only have 30min. you can create your own preset with CBR 7.8MBit, and dolby digital audio@192kbit/s for stereo-sound.

there are also some adjustments necessary on the dolby-setting to get an 1:1-sound, you need to set the dialoge-normalisation to -31dBfs and you need to turn off the compression on the preprocessing-tab, otherwise it´ll be compressed.

the main problem is the presentation!

if the video will be presented with beamers, you need to know how the players are connected to the beamer. if they use a composite or component-connection the beamer wil expect interlaced material. if it´ll have an HDMI-connection you need to look for the dvd-player-settings as well, what it´ll output to the beamer, is it progressive or interlaced.

keep in mind that something needs to do the de-interlacing! maybe the beamer, maybe the player itself.

could you please tell us at what framerate you´ve shot the films?

cheers

Thanks a lot for the response.

My footage is almost all created in After Effects, so I have a lot of control, it’s simply a question of rendering it correctly. I have been rendering the files at 29.97, animation codec, and progressive.. Next I will go through compressor, or.. go directly into DVD sp.

Unfortunately, it seems as though DVD studio Pro is not even capable of a standard def progressive DVD. So even if I could get the deck and projectors speaking progressive, I would still end up with an interlaced image! So frustrating!

We’ve been working in interlace in the past.. I just thought progressive would probably help me with all of the moire, but I can take care of that with filters, as I’ve been doing.

So do you suggest using compressor with a constant bit rate of 7.8.. or let DVD studio pro do the encoding?

Thanks again,
Hillary

[Hillary Leben] “Unfortunately, it seems as though DVD studio Pro is not even capable of a standard def progressive DVD”
Not true at all. But you do need a Progressive player hooked up to a progressive monitor/projector via the component cables.

Always encode with Compressor and not in DVDSP for best results.
7.8Mbps is a little high, I recommend 7Mbps CBR but max should be no higher than 7.5.

Thanks for your help..
What version of DVD SP are you using? In 4, it seems as though the standard progressive option is gone. 🙁

I’ve been reading on this all day and still haven’t found a way to do it…

[Hillary Leben]

ALso, here are the specs for the projector. I was working with the deck today.. it had “progressive scan” written on the front of it.

These are the specs I have on their projector:
Sony VPL LCD projector
Standard zoom lense
15 HD-M to 5 BNC-F Breakout Adapter
100′ RGB-HV cable set

Thanks

Never recommend you encoding in DVDSP, use compressor.

But you need to export out of AE as 29.97 PRogressive, then in Compressor you set the field dominance to Progressive.

DVDSP will show in the info it as 29.97i (even if it is 23.98p) because that is DVD spec, but Progressive DVDs know how to put the progressive frame back together. It is confusing but this is a DVD thing and not a DVDSP thing.

[Hillary Leben]

Thanks for this.

I will run some more tests!

I did render progressive. I encoded progressive. When I viewed it from the player, I’m sure I saw fields. I was using RCA cables into an LCD screen.

Could that be why?

[Michael Sacci]

RCA is the kind of ends not the cable. If it is not component cables 3 for video and you set the DVD to output progressive in its menu then yes it is interlaced.

[Hillary Leben]

You rock!

Thanks so much for all of this info.

The only detail I am still not clear on is how, exactly, to set DVD studio Pro so that it will output a progressive disk? Where, exactly, is the setting? Is there a setting? Or should it burn progressive if the footage is progressive?

All of the field stuff is set to automatic, and progressive is not an option.. there is the 480i that you mentioned. Those are the only places I see options in the standard menus.

If you have encoded all the video before hand there is nothing to set. There is no such thing as a progressive dvd, just progressive assets on a DVD.
