DVD Quality
Hi friends!
I’ve done a search on this forum and have come up with a lot of good information, but I still need a little more help.I’m useing Vegas 9 Pro and DVD-Architect 5.0b. I’ve exported my project from Vegas as a DVD-A 24FPS Progressive file and separated the audio file as a separate AC3 file. The output of the video file is 720×480 24P with 3:2 pulldown.
When I play this file back in Windows Media, it looks great and it’s smooth. When I play it in DVD-A, it’s smooth, but the quality is degraded. When I burn it to DVD, the quality is poor and the image jumps. In fades and transitions, it skips pretty badly. At other random times, digital blocks appear on the screen in odd green colors.
When burning the DVD, the only things that are claimed as needing re-optimization are the title audio parts (which is a 30 second wave clip).
This is a 2+ hour concert so I’ve had to render at around 5.5 Mbps versus the higher 8Mbps. If I have to, I can split it to 2 DVDs, but I’d prefer not to. I could see how the quality would clearly be better, but the skipping and jumping shouldn’t make a difference.
Note – the skipping and jumping only occur on the DVD – they are not in the actual video files.
Please help!!
Best wishes,

I would render without the pull-down. By adding 2-3 pulldown you are bringing the 24p back up to 60i. This is wasting 6 frames per second. Over the course of 2 hrs you could be saving of 43,200 frames or an extra 30 minutes of footage. This way you can use a higher bit-rate. Most DVD players can handle 24p without pulldown and they will add the pull-down on the fly as it plays. This gives you more room on the disc.

John –
Thanks so much for the prompt reply!
One additional question –
I’ve attempted to render as 23.97 or 24 FPS without 3:2 pulldown and I keep getting an error message as soon as I hit “Save.” The message says:“An error occurred while creating the media file Disc1OutputWOPullDown.mpg. The reason for the error could not be determined.”
The only change I’m making is the removal of the pulldown.
Have you seen this before?
Thanks again!

I am not seeing this error. What version of Vegas Pro 9 do you have? Make sure you are using 9.0c. Also make sure you don’t have any “codec paks” installed which could interfere with Vegas’ processing of it’s own codecs.

Thanks again John.
I’m still having issues. I have the most recent patches of Vegas with no extra codec patches added.On top of those issues, when I do put the video track into DVDA, then choose properties, it shows that it is not progressive scan. In fact, it shows a different scan rate altogether! It shows 29.97 with a 4:3 aspect ratio (even though it was recorded and rendered in a native 16:9)
I’m really frustrated at this point. It’s taking me hundreds of hours to edit a 2 hour video from 2 angles and the quality is horrible.
Cheers-

Clearly something is not correct with your render. You should be using the MPEG-2 template called DVD Architect 24p NTSC Widescreen video stream with a frame rate of 23.976. This works for me and shows as progressive 16:9 in DVD Architect.

I had the same problem, did a google search and found this forum. I’ve ultimately figured out the solution on my own: create a NEW PROJECT FILE
redo all the settings, i.e. best quality, 23.97, 16:9, ect, then try rendering without pulldown- worked for me.
