Where am I going wrong

Movie Studio 12 .... (DVD Acrh 10)

Advice is to encode using elementary streams ...

so for 1Hr 20min PAL SD video - this created 2 files:
Audio.ac3 112,897Kb
Video.m2v 4,409,374 Kb

That gives a total of only 4.5Gb surely this should fit on a 4.7Gb DVD ?

I'm creating a single movie DVD, PAL ... no menus, no angles .... where am I losing 470,000 Kb ?

You should use a bitrate calculator (search it) - before creating your elementary streams - if you want to simply add the two produced streams after rendering as you seem to imply you are doing now -

THEN beware it should not add upto more than 3.9Gb for a maximum filled DVD capacity - you cannot write amount of 4.7Gb ...period.

The OP could read the thread below as well
rendered file too big

OK .. was using BitRateCalculator ... but had total size as 4.5Gb ... didn't think there was so much overhead for non-menu single movie DVD

Thanks

Interesting (and still frustrating for me)
I used what I'm told is far more accurate calculator:
http://dvd-hq.info/bitrate_calculator.php

Put in my duration of 80 mins, used 320kb as audio (AC3), set Media to be PAL and it gave me VBR settings of
9200 max
7100 average
2800 min

Put these in MainConcept DVD PAL program stream ....
Rendered .... but when I drop files into DVD Architect ... it again fails ...
advising file size is 109% at 5.1Gb ......

Why ? .... calculations do not show this.

Bit rate calculators vary in their applicability to a situation - never use just one only - search this forum, the VegasPro forum and the Movie Studio forum for forum member recommendations.

Whatever you did in your calc is weird, one, the audio rate is nearly double what it is supposed to be, and the 7000 average would be for a high quality program encode of video that is about 50 minutes in run length. You have already said that you have 80 minutes to cover - so your average is going to have to come way down to about 4500 average which will be mediocre quality if you want a single disk of this program.

DO NOT USE THE DVDA ESTIMATE
"If" your media is compliant, prepare the DVD folder, re-open the project, and burn.

OK ... Somewhat strange ... I tried many times with different VBR values to try and get a Render that DVD Architect would accept.
Kept complaining file size too big, values were confirmed by BitRate Calculator as correct. (recc ver seems to be here: http://dvd-hq.info/bitrate_calculator.php )
Using VBR of
Max 9200
Avg 7100
Min 2800

and 320Kb for ACR3 Audio

Finally created 2 separate elementary stream files....

Opened DVD architect ... dropped in Video file .... program just stalling ... spinning wheel icon ... never proceeds ... does this every time.
I then tried dropping in the AC3 file instead .,.. that loaded audio & video OK ..... so do I have DVD Architect bug ?

I then went to burn and it completed happily with no re-compression ..... even though if I do same thing with non elementary streams it says it won't fit.

So I have at least completed DVD .... but what a huge amount of time and DVD Architect 'blockages' to get there ... is DVD Architect particularly bad at working out what it can put on a disk ... would seem fundamental ?

Yes, it's notorious for it. If you've prepared your file in Vegas, and you know it's within the size, add a bit for your menus. Go ahead anyway.

An estimate is an estimate. If Sony's software made non-conservative estimates, there would be more complaints.
The need for separate, compliant streams is well documented and explained elsewhere.

You do not need to understand the rationale behind the requirements for them to work for you.

If you are interested in learning more, here is the documentation.
Either way, best of luck.
