alright, heres whats up, i caputre the footage from the dvx (shot at 24pa) and bring it into a 24p timeline. so far so good. i edit it, then export it as such:
1.jpg

2.jpg

and even then, i am beginning to see some decrease in quality. but it's still alright.

then i import in encore as a new timeline. burn it with these settings
3.jpg

and the quality looks like it was shot on my old digital camera, it looks like it wasnt shot in 24p and it just plain doesnt look good. am i doing something wrong?
 
Re: HELP!! P

..id start by unchecking "recompress" on your export settings in premiere. then check the quality of the file before encoding to mpg2 with encore to be sure its good.. once you know that then you can narrow it down to the DVD encoding if theres a quality issue. then i would set up encore to burn a 24p DVD instead of a 29.976 one. and change your "N frames" setting to 12 instead of 15.
 
Re: HELP!! P

Encore can't encode your video as 24p.

You should use Premiere's File->Export->Adobe Media Encoder to encode as a 24p MPEG.

You'll see more or less that same MPEG Encode dialog box. Make sure you are on the MPEG-2 DVD format. Select 23.975 Progressive. Under GOP settings, change N Frames to 12. ( A Group of Pictures, or GOP, should be 1/2 second on a DVD. Setting it to 12 will acomplish this on 24p.)

When you bring your .mpv (MPEG Video Elementary stream) file into Encore, Encore will claim it's 29.97. Don't worry. It's 24p with the necessary flags (Top Field First and Repeat First Field) every so many frames so that a DVD player can "reconstruct" the pulldown so that it can be shown on an NTSC TV.

mobiledeli - Nice job posting the screen captures. That really helps. I wish more people would take the time to do that. Problems can be solved quicker.
 
Re: HELP!! P

yeah i figure they'd help, and thanks for helping me, but i want the highest quality possible, so what sould i do about the bitrate in cbr or vbr, 1 pass or 2. etc?
 
Re: HELP!! P

doh! yes.. set up premiere to expot 24p not encore.. encore cant do it as kevin said. sorry, the export looks the same.  ;)

..and VBR 2 pass
 
Re: HELP!! P

As Neil said, stick with VB2 2 pass.

VBR stands for Variable Bit Rate -- it means it can use a higher bitrate for complicated scenes with a lot of motion, and a lower bitrate for scenes with not much motion. I used to think "AH, I'll just go CBR (constant bit rate) with a high bit rate and it will ALL be high quality." But what I've heard is that VBR is better, because with CBR, in order to keep the bitrate constant, quality will need to vary over time. And that's something the viewer might notice.

So Minimum, Target, and Maximum bit rates? Think of Maximum as the rate you want to apply to a scene with a lot of motion, Minimum to a scene without much motion, and Target as the average. The settings you show on your screen shot are good settings, although the 8 maximum could cause problems on some players reading DVD-R discs. I usually stick to 7 max. (It may just be my old player, though.)

BTW, the bitrate will also dictate the size of the file, and how much video you can fit on a disc. That's another advantage of VBR -- by using a lower bit rate for low-motion scenes, you can fit more on the disc. I doubt Hollywood movies would fit on a DVD without VBR.

You also want to know about multiplexing. Multiplexing is how the audio and video are combined into one file. This is best left to the authoring app -- otherwise it might need to demultiplex and remultiplex -- so the setting of None is appropriate here.
 
Re: HELP!! P

Going through the same process... how come it won't allow me to select progressive when i select 23.976fps?

I think it's automatically assumed the 23.976 is progressive, so it disables the control. No such thing as 23.976 interlaced.
