targetsectors adjust

[raquete]

i read the post about hidden settings and i want to test cce and HC encoders with dvd-rb free version. will be a fast tests to compare the quality of this encoders.
i have some dvds(cartoons)with less than 3,8Gb to be used in this tests and i need to know how adjust the targetsectors to 2,5Gb final size in video_ts folder.

thanks.

just do a search on targetsectors

just do a search on targetsectorsgreat.was a fast answer but without target because was postedi read the post about hidden settings.(did you read there?)thanks

someone else can help me please?

Hello

here is the formula :

Target sectors=(2236400/ 4.32) X Target Size(in GB)

From the help file of Dvd Rebuilder

Target Output Size

TargetSectors= nnnn
CCETargetSectors=nnnn
ReJigTargetSectors=nnnn
QuEncTargetSectors=nnnn
HCTargetSectors=nnnn


Use Sectors, 1 sector = 2Kb.
Example: CCETargetSectors=2236400

As a reference the default for DVD-RB is 2236400 sectors and the maximum for a DVD-5 is 2297888. You should always leave a some room for error.

TargetSectors will be the default for all methods. Other, mode specific, target sector settings will override it when using that mode


2,5 G = 2560 Mb = 2621440 Kb = 1310720 sectors

A sector is 512Kb and as a Mb is 1024Kb you can simply try to find the equivalent in Kb => 2.5*1024*1024= 2621440 then divide to 2 = 1310720 , then leave a bit space for oversize due to the encoder , say about 2,5% =32768 and you got 1277952. Remember a Blank Single Sided DVD is not 5,0 Gb but about 4,37. BYE !!!

thank you very much.(you all)

Ok... now I'm confused.

A sector on a DVD is 2048 bytes. A gigabyte is 1073741824 bytes. So you could come to the conclusion that 2264924 sectors in a 4.32GB target.

The reason 2236400 was used as the default is because the target is used to calculate bitrates... but there is multiplexing overhead involved in a final DVD (NAVPACKs, header information in all packs, and padding as necessary to fill sectors). The goal was to hit 4.32 (rather than 4.37) so there would be a little overhead (~50MB) for outside sector instability (it happens a lot more often than you think) and encoder variability.

Frankly I could have made it easier... but originally it was only designed to be used internally by DVD-RB -- and if I changed it now I'd create a lot of angry people who have found just the number they like.
