DVD Architect balloons my video size!

Bansaw wrote on 8/28/2006, 7:28 AM

I've just done a set of five separate videos to be burned in one DVD, and they total 4.4Gb. Just a nice size to fit on one DVD.

I am using Sony DVD Architect and it wants to expand this all out to 6Gb !!! (My front end animations are nothing really).

I have rendered these five videos at approx MPG2 720x576.

My question is: can I re-render these videos at a lower screen-size or bitrate (or something else) to reduce their size but, at the same time, maintain a certain quality so they can fit on one DVD?

Thanks.

Just STOP! Don't do anything else . .wait ..

Are you actually being STOPPED by DVDA from producing a DVD? If not, just crack on! If you KNOW that you have plenty headroom to do the thing - DO IT!

Do some searches hereabout and you will find much angst and hairpulling at that lil ole sign saying 5 ? 6 ? 7 gbs. Most advise - IF you know you are well within - just burn that sucker!!

Another thing to do is to RAISE the actual Preference of the DVD to something outrageous - that's what I did - 'cos I knew I was well within - and BURNT it.

But do some searches hereabout to confirm the advise.

PLUS what I've used, as another way, is to download the free DVDShrink. This will rummage about in your now prepared folder and then burn this using the DVD burner. I've got Nero as being my burning s/w and it uses that.

DVDA? Totally awesome authoring suite of tools - brilliant! BUT it is tres conservative with the GBs.

What format is the audio? Is DVDA trying to re-encode the audio to PCM?

Thanks for the advice.
I will check out the audio thing. I am convinced that if I reduce the bitrate or screen size then it will be a happier scenario, but I just don't want to lose too much quality.

What would you go for, reducing bitrate or screensize?

Tks both...

Screensize does not affect the file size. Only the bitrate will change the file size.

Don't do either. If you have prepared the MPEG-2 and AC3 files correctly in Vegas, and if the total size, as reported by Explorer (right-click on both selected files -- the audio and video -- select "properties," and record largest number) is at least 10% less than 4,699,979,766 bytes, you should be OK to burn. Burn it to a rewritable DVD, if you want to test first. Or, do a "simulation" burn in Nero, if you have that application.

Remember, as already stated, to take into account the size of the audio file. That gets added to the video size. Use this Bitrate Calculator to get the proper bitrate for encoding in Vegas.

DVDA does not balloon video size.
