optimize 11 gigs to fit 8.5
I have an 11 gig program and I can’t get it to optimize down to 8.5 by either fit to disk or changing the bit rate. What am I missing?

Is this an already rendered program?
If yes, how long is it and what format are you rendering to? -
I am trying to keep quality of final product high. The program is 4 hours in length. Should I have compressed it when I rendered it I can do it again?
I thought you did the compression during the DVD prep phase. -
Yes I rendered it using the Main Concept mpeg-2 rendering engine in Vegas, It is about 4 hours long.

I get this message when I use the fit to disc button. “Media file is too big and could not fit into single disc. Consider making more media assets available for re-compress or removing some media assets….

To get 4 hrs of video into an 8.5GB DL-DVD you’ll need to use an average bit-rate of about 4,800,000. You can also render to AVI and let DVD Architect fit it to the disc.

Rob, I’m not sure why you’re getting this message as DVDA should recompress it for you.
Having said that, I prefer to set my bitrate in Vegas as DVDA can sometimes do nasty things to your video when it recompresses.
I’ve been using and recommending the bitrate calculator found at https://www.johncline.com/bitcalc110.zip for a long time now.
The only changes I make to the default settings are to set the Safety Margin to 5% and the Kilobit size to “1 Kilobit = 1000 bits”.
Both of these options are found on the seconday screen accessed by clicking the “Settings” button on the main screen.
For a 4 hr. video, I come up with the following VBR numbers.
2,544,000 / 4,248,000 / 7,432,000
Due to the program length, do it as a 2-pass encode.
This will take longer but will get as much quality as possible on your finished DVD.
BTW, this is for a dual-layer disc, correct? -
Mike
Yes it is for a dual layer disc.
You gave me the same advice about last years DVD but I had forgotten about it.
I am having trouble with another title that is only 3.6 gigs in size that when playing this back on the final DVD I get vertical lines through out the video that are off set it looks to be about 1 scan line; will this help that also?
