Timeline vs. DVDA
on Jul 10, 2012 at 4:50:12 pm

A DVD produced directly from the timeline seems to me to be sharper than that produced via DVDA using an MPEG2 DVDA template. I need menus so would be very grateful for pointers as to how to optimise picture quality. The Vegas file is 1920x1080, 25FPS PAL.

Dave,

If your source mpeg is too large DVDA will have to re-encode it. You have much less control over the renderer in DVDA. That is why it is best to produce a compliant file inside Vegas that will not require compression in DVDA.

I suppose you are already using the Mpeg-2 templates designed for DVDA. What size is your rendered video file(s)?

When I use the DVD-A template I always adjust the quality slider to 31 under Customise. I think it defaults to 17.

My system specs: Intel i7 970, 12GB RAM, ASUS P6T, Vegas Pro 10e (x32/x64), Windows 7 x64 Ultimate, Vegas Production Assistant 1.0, VASST Ultimate S Pro 4.1, Neat Video Pro 2.6

Thank you both for your responses.

Jeff: I below is an image of the DVD video files produced by DVDA.

Nigel: I too chose 31 for quality.

I forgot to mention that the duration is 42 minutes.

Dave,

What is the size of the files you are plugging into DVDA?

How long does the build take when you press Make-DVD?

I'm definitely using the Vegas DVDA template! It looks to me as though this is a bitrate issue,- but thanks for your help!

[Dave Edwards] "I forgot to mention that the duration is 42 minutes."

In that case, use a custom CBR setting of 8,000,000 for your MPEG-2 encode (i.e. render).
I use this for any program under 70 minutes.
Anything longer and I use a bitrate calculator to determine optimum VBR settings.
My favourite is the one found at http://www.johncline.com/bitcalc110.zip
