Exporting 1080i to DVD
I edited some film in Adobe Premiere 2.0. It was shot in 1080i (not 24P). But I am having trouble exporting it in high definition. Premiere only exports it to DVD in 720x480. I would like to export it in it's original quality, 1440x1080. I was able to export a mpeg file in the correct resolution, but don't have any DVD creating programs. What are you guys using to obtain a high def DVD? Any free programs? Thanks
Unless you have a HD-DVD burner why would you want to export to HD-DVD? 720x480 is the native resolution for NTSC DVD's there is no way around that one.Originally Posted by gooseman271
The only thing I can think of to help you is to get a media player to play and HD resolution file on your TV. Do a search here there is a thread already on that.

You can export back to 1440x1080 m2t file using Adobe Media Encoder. It won't be original quality because there is one generation of compression. Still, the quality is amazing.
Ok, I did not know DVDs were 720x480. So I guess it will never look as good as the m2t file. But is there anyway to maintain the correct aspect ratio?
Yes most Mpeg2 compression software will do it. Even most DVD authoring programs will such and Encore.

Ok so I downloaded Encore and tried burning it there, but the aspect ratio is still slightly off. The original aspect ratio was 1.3, but it is showing as 1.5, which makes the image skinnier. How is this fixed within Encore?
I can not find an answer for this anywhere and am confused as to how it has not come up. The original video is 1440x1080 but has to be converted to 720x480 to fit on DVD, that's fine. But these have different aspect ratios. So it is stretching it vertically. So I am thinking it might have to be letter boxed. Clarification would be appreciated.
I wish I could help, but since I am a Mac man I have no idea how Encore work, just of its existence.

I think I found a solution. Probably not the best way but I think it will work. Since exporting to DVD increases the height of the image, I am resizing the height of the video by trial and error until I find the correct aspect ratio. Unfortunately I will waste a few DVDs in the process.
These are the aspect ratio
HDV: 1440x1080 pixel ratio 1.33
DV Widescreen: 720x480 pixel ratio 1.2
Did you create your preject with Preset Adobe-HDV 1080i (Sony 60i)?
You can use Adobe Media Encoder (File, Export) in Premiere Pro to export your timeline to MPEG2-DVD in 720x480 NTSC 16:9. You might not have these settings if you are using the Trial version of Premiere Pro.
If you successfully create those MPEG2 files, you can import to Encore to do the DVD authoring.
In fact, if you are not creating fancy DVD menus but just stright one timeline to a DVD, you can do it by File, Export, Export to DVD in Premiere along.
Export to DVD DOES NOT increases the height of the image.
You are reducing height from 1080 pixel to 480 pixel
Vs 11 Dvdx3
Ulead video studio 11+ can apparently burn DVD X3 (i think it's called that) this burns HD on to normal DVD media (using a normal DVD writer).
These DVD X3 's can be played on a HD-DVD player (not all HD-DVD players support DVD X3).
You can apparently store approximately 20mins (open to correction here) of HD on a normal DVD using this method.
I think this is the cheapest way to burn HD at the moment but as pointed out not all HD-DVD player will play these disks, so best to try the trial and see if it works.
I personally am looking to buy videostudio 11+ when it shows up on the shelves here in the third world (currently use sony movie studio plat).
As you mention HDV and DV widescreen have different aspect ratios. DV widescreen is more rectangular than HDV. In order to have kept the same aspect ratio of 1.33, the HDV image would have to been 720x540, but since DV height is 480 pixels, it has to instead squeeze the picture. The "export to DVD" function in Premiere does not compensate for this.
I think you confused about screen aspect ratio and pixel aspect ratio.
Widescreen format is always 16:9.
For HDV standard, in order to fill the 1440x1080 to a wide format, each pixel is scratched 33% wider, i.e. the pixel aspect ratio is 1:1.33.
NTSC DVD standard is always 720x480.
For NTSC widescreen, each of the 720 pixel scratched 20% wider to fill the horizontal space, i.e. the pixel aspect ratio is 1:1.2
For standard NTSC 4:3 screen, each of the 720 pixel is squeezed 90% narrower, therefore the pixel aspect ratio is 1:0.9
There're lots of information on the web about pixel aspect ratio.
If you use the Export to DVD feature in Premiere, it will take care of it for you. Simply says, Premiere won't generate a 720x540 video for DVD output because DVD (NTSC) is alayws 720x480

Hmm, I think I was confused about that. Thanks for the clarification. Premiere is still stretching my DVDs however, I'm thinking its just my DVD software that might be playing it wrong on my screen, so I'm going to try and find a real DVD player to see if that's the issue.
Very frustrating. I found that it was not Premiere stretching my DVDs but instead my crap HP Quickplay doing it. Spent all last night trying to figure it out. Sorry for all confusion. At least I know it works now. Thanks for the help anyway.
