Production is

H254AVC
MPEG 4 640 x 480 24P
DVD is NTSC
I could send aclip where you can see the bad images and the original as well.
Thank You
Hi,
Before you share example clips, maybe look at this:
From what you write I understand that you first produce H264AVC MPEG 4 640 x 480 24P files before you write a DVD? What kind of DVD software do you use?
My feeling is that the degradation of the video clips might be caused by the steps in between. If you produce to MP4 640x480 from HD original (1920x1080) then there is a lot of degradation already. The next step would be to DVD, which has MPEG2 as standard (720x480). I can imagine that coming from 640x480 to 720x480 is less than coming from 1920x1080 to 720x480. This two steps conversion (from original to MP4 and from mp4 to MPEG2) will not improve the quality.
It depends also a bit on the kind of DVD writing software you use; it has to convert the mp4 files into the DVD standard MPEG2 format. (And maybe on the DVD writer itself as Muzza suggests, but if the DVD itself pays well, then I assume that the DVD is technically correct).
So my suggestion would be:
Try (maybe with a small clip first to save time), to produce a clip with PD using the MPEG2 and select from the options list: DVD HQ 720x480/60i (8 Mbps).
After this clip has been produced look at the quality of the production on your PC. It cannot be as good as the original clip because that was true HD, but it should be better than the 640x480 you used before? Maybe check this with the VLC video media player. (You can both look at the original and the produced file to see the difference).
Should the produced file already be showing problems then we have to look at the PD process. If the newly produced file is already better, then look at the next step, the production of the DVD. If you feel comfortable enough write this test file to DVD and see what happens. My hunch is that the DVD should already produce better results because of the better in-between steps.
In the following stage, you might want to look at why using DVDs. From the above and your experience, it becomes clear that with DVD you can never get to the results of the original camera recordings, which is a shame. Maybe look at using Blu-ray, which can hold true HD format (if it should be a disk medium), or look at using YouTube, Vimeo and the like, to get to optimal results for your audience?
Looking forward to seeing your results.
