Default Rebuilder Target Sectors

I have looked around, but have been unable to find out exactly. I wanted to set my target sector setting to 2265000 as Blu has mentioned before.

Do I just add the line into Rebuilder Config.ini file?? Or is there already a command line for it that I have missed ?

Under section "Options" in the rebuilder.ini file:

Add this line

TargetSectors=2265000

Just be aware that the value is more or less something you never learn how to set. For some movies that value will work - on others it will oversize the outputed files.

I'm using 2260500 - and I have only had one DVD that gotten oversized with that value. In most cases I end up with something around 4465-4475. (Using HCEnc)

So it may change the output depending on the source, keeping you continually guessing? I am assuming the smaller the Target Sectors number, the lower the output file size, correct?

I use primarily Procoder2, and the output has been very very close to limit, I just wanted to ensure I don't run into a sizing problem and have to redo any encodings.

**Actually, if I have encoded a film that comes out to be, for example, 4.8GB. Would it be recommended to run it Rebuilder again? Or would Shrink be sufficient to compress the remaining amount and not experience any negative effects?

It'll never be that high. At most on that setting, you'd get 4.38 - 4.40Gb, in which case, Shrink is a quick and easy way to get it to size.

BTW: I have found HC works on the basis of Sectors * 1.013 (more or less) and Procoder 2 to be damn accurate in respect of sectors (i.e. 1.000) but others may have different views.

Regards

Just to share my experience in the 5-6 DVD's I have used this setting with. Never faced an oversize, its within the burning limit of the DVD.

The value of 2265000 is too high. If the disc sizes perfectly with that setting it will be too big to fit on a DVD+-R.

I would also never recommend running shrink against the result. Contrary to what many think -- even small compressions with a transcoder can cause problems in the output. There are a lot more factors at work than the reduction percentage. It's kinda' like using a precision file to create a sculpture and then noticing it won't fit in the door, so you use a chainsaw to take off an additional inch.

But then... it's your disc, you can do whatever you want.

Perfect output size is the TargetSector value * 2048 * 1.015 (to cover pack and navpack overhead). The variations come from the encoder... as they never size perfectly.

But once again I will emphasize that you are better leaving the value at the default. You are taking the risk of using the historically flaky outer sections of the disc... and possible oversizing -- all for an amount of space that will not measurably improve the video...

Yes Furiousg the first time you spend hours doing a backup and your burning program chokes on it, you will be furious indeed!

I tried to be a wiseguy once and upped the default a little, ended-up with a titleset that didn't quite fit. I was luckily able to overburn the disc a little, and it worked, but I set to default again and haven't looked back...

+R = 4483MB
-R = 4489MB

I set it to 2265000 and the final size using ProCoder is 4485MB (+ 1MB for burning => 4486MB), which is enough with DVD-R but not DVD+R
