DVD size increasing after authoring

[jak_omo]

hi DVD fans,

After mastered a lot of DVD, now i am stucking.
I tried it on DVD-lab Pro v1.5 and Ulead DVD Workshop 2 (+updates) an get always the same result.
During authoring and finished the work ready for start authoring the required space for DVD is shown at Workshop 2 as 4.2 GB.
After finishing authoring the DVD folder size is increased to 4.52 GB so that is not fit a DVD5.

At DVD-lab the same problem, the DVD thopography indicator shows that the work can be fitted on a DVD5 (4,6GB) but after authoring process is finished it wont fit DVD5.

I've tried in both programs to author an write immedeatly to DVD but everytime i get an error while the files can be fittet o an DVD5.

The menu is about 20MB with background audio an 3 pages and seems not to be the problem.
The video files are before authoring at 4.15 GB, this shouhld also not be the problem, because at futher authored DVD's the size of the mpg files where also at 4.15GB.

has anybody any suggestions what i made wrong or what is worng?
thanks in advance..

Maybe it is a typo but if 4.52GB is too big for DVD5, how you thought that 4,6GB should fit?

Hi-

At DVD-lab the same problem, the DVD thopography indicator shows that the work can be fitted on a DVD5 (4,6GB)

Yes, the sizes you give are a bit confusing, but since a DVDR holds only about 4.37 GB, it sounds to me like it's just too big. From:

https://www.videohelp.com/dvd

DVD-5, holds around 4 700 000 000 bytes and that is 4.37 computer GB where 1 kbyte is 1024 bytes* . DVD+R/DVD+RW and DVD-R/DVD-RW supports this format. Also called Single Sided Single Layered. This is the most common DVD Media, often called 4.7 GB Media.

hi,

here are screenshots from DVD-Lab:



The indicator at the bottom for DVD5 is green with a size of 4.60GB.
Movie 34 is the last movie on DVD so that all data is fittet on DVD5.

(to compare the right picture shows a oversized DVD, the indicator is going red over a size of 4.70GB.)




The estimated DVD size shows that all data on DVD is at 4.28GB and so unter the (calculating methods 1000/1024) limit of 4.7GB/4.36GB

The diagram in the upper right shows that the DVD is not filled up (red is filled, green is free space).




After finished authoring process the windows explorer shows a size of 4,45GB (at 1024 calculating).


here the screenshots from DVD Workshop 2:



During authoring the total DVD size is shown as 4.2GB (at 1024 calc).




Before starting authoring process the Authored DVD size is again shown as 4.2GB and the required space on DVD also 4.2GB, the available space on DVD is 4.4GB (4.37GB).




After finished authoring, explorer says that the size is 4.52GB (at 1024).



It seems to be that the authoring process adds some MB to the MPG-files because the menu as a size about ~15MB

The MPG's used for authoring are recoded with TMPGEnc from MPEG-1 to MPEG-2. they have a total size of 4.15GB (at 1024).

Other authored projects had also the same sizes of 4.15GB for the used MPGs, they had also a Authored DVD size from 4.2GB (workshop) and 4.59GB (dvdlab).
The finaly authored folder size was 4.36GB (4480 MB) and fits a DVD5.

so what can be wrong with them?
are the mpeg-2 corrupt?

I think the size is increased because of Navigation Points, padding streams,... added to vob files.

Last week, I had a similar problem. I simply reencode my audio from 256 kbps to 192 kbps to solve the problem.

Yes, the size increases during authoring, because of muxing overhead, and also the things that cd090580 mentioned:

Blank DVD-R 4,489MB 4,706,074,624 bytes or 4.383GB
Blank DVD+R 4,483MB 4,700,372,992 bytes or 4.377GB

And if you make an Image file for burning, that also adds around 1 MB. Maybe you need a better Bitrate calculater:

https://www.videohelp.com/calc.htm

If you hit the "Advanced Mode" button, you'll see that it allows 25 MB for all the overhead. That's usually a bit too much, but at least you won't go over.

hi-

after some calculation i've found that that the size of one video track added to DVD is increasing after authoring at a amount of ~20-25MB. (maybe depend of existing chapters..)
The more tracks, more increasing - 5 Tracks added 20MB per file, 14 Tracks added 25MB per file.

In this project there are 14 tracks. The authored size is 4.41GB, mpg files size is 4.06GB.
The difference is 350MB, per file +25MB..

it's interesting to see that the authoring software shows that the project fits on a DVD5 but after creating a folder the files are to big for a DVD5.
i would say its a bug, isn't it?

the solution is to encode my files with a lower bitrate so that the mpg +25MB per file fits on a DVD5.


thanks for your suggestions.
