DVD-A.cannot "fit to disc"

[Paul Kellett]

I've got a finished project,rendered as DVD-A widescreen video,with vegas.
When i open architect,new project,project now in timeline,113% of disc space used,when i try to "optimize" then "fit to disc", i get a pop-up saying Media file is to big.Consider making more media assets available for recompress or remove some media.
Pulling the bit rate down makes no difference.
Also changing the in and out points on the timline makes hardly any difference,ie pulling the right hand side out point all the way to the left hand side in point only makes the project shrink to 110%.
The project is 1hr 40mins long,or 5.297mb.I'm using a standard 4.7gb dvd-r.
I burned the project with nero but it's came out jittery.
Has anyone got any advice ?

Paul.

OK i just tried to import the same project's video stream only,110% of disc,teh i closed that and opened the audio only, 142% !!! of disc space used,
how can this be ? 142% + 110% doesn't equal 113% !!
What's going on here then ?

First of all, DVDA has a long history of incorrectly reporting file sizes.
In your particular case though, your final render is still too large to fit.
You want to keep the total of all assets under 4.3 Gb. for a single-layer DVD.
For a 1 hr. 40 min. project, my bitrate calculator comes up with the following sets of numbers:
CBR: 5,500,000
VBR: 8,000,000 / 5,500,000 / 3,300,000

Thanks mike,so which bit rate should i choose for the particular project ?
And how do i know in future which bit rate to use for a particular size project ?
And lastly,so DVD-A's "fit to disc" button is a waste of time then ?

Thanks,Paul.

Mike,
Yes i see know,you mean maximum bit rate>8,000,000, average>5,500,000, minimum bite rate>3,300,000 or a constant bit rate o 5,500,000.
This will be good for how long a DVD ? 1 hour ?
What do you recommend,constant or variable bit rate ?

Thanks,Paul.
