Render for DVD from V4 to DVDA

OK my vid is 1:33:40
puts it just over the line fitting on my DVD media (4.37) if I use the Render default for DVDA rendered fromV4. 'DVD Architect NTSC video stream'

The bit rate calculator tells me 6,315,541 If audio at 192kbits (ac-3)
I tried this setting but the video was blochy bad.
Can someone suggest some setting please.
Should this be set as constant bitRate?

Regards,
W

You should get pretty reasonable video at that data rate. It certainly shouldn't be "blochy," although I'm not quite sure what video defect that is describing.

Things to look for:

1. In the Render As dialog, "Save As Type" should be set to "Mainconcept MPEG-2 (*.mpg)." Template should be set to "DVD Architect NTSC video stream" (which is what you said you have set). The "stretch video ..." box should NOT be checked.

2. Click on the Custom button. On the project tab "Video rendering quality" should be set to "Good." The "best" setting will not provide any real improvement and will slow things down (it is useful primarily when rendering still pictures). On the Video tab, make sure that the "Video quality" slider is set all the way to High (31). "Insert sequence header before every GOP" should be checked. Maximum should be set to 8,000,000, Average should be set to your 6,315,541 (or slightly less, to give DVD Architect room to create menus), and minimum should be set to 192,000. At this bitrate, I would definitely use variable bitrate (I only use constant bitrate when the average bitrate is 7,000,000 or higher).

Are you viewing this on your PC, or are you viewing it on a TV? Also, if you are viewing it on a TV, have you created a DVD in DVD Architect and are you playing this DVD on the TV? If so, it is possible that DVD Architect is screwing up something. Open your project in DVDA and use the Optimize option (in the File menu) to see if any of your video is being re-compressed. If so, this could very well be your problem. This can happen if your DVDA project settings do not match the format of the video you have created in Vegas, or if you simply have more video than can be fit on a single DVD.

Best for 1:34:00
2-pass VBR
max 7 800 000 bps
avg 6 200 000 bps
min 3 700 000 bps
DC coefficient 10bit

2 pass is not available on DVDA 1.0 Even a 1 Pass shouldn't look too bad at that rate unless you have lots of footage of dark areas and your using the default minimum setting of 192,000 Kbps. I would guess that you should try keeping your minimum and maximum settings within about 2,000,000 on either side of the average and it should look pretty good.
