TWO Questions about file size

[noah97]

I just tried to copy a 2 hour concert movie that was over 6 gigs.
How can this be... I thought that a 2 hour DVD is normally around 4.7

Second question; If I use DVD 5 to put the above movie on a single layer DVD how will the quality compare to using DVD Shrink which shrings it down to 4.3G

Thank you

Run time and file size is two completely different things.

Some movies rip with folder size of under 4.7, then some are 7 or higher. Obviously the more you compress the lesser the quality.

It all has to do with bitrate/original encoding, see links below:

In addition to the excellent advice so far,

Some of the confusion arises from using both decimal and binary measurements.
Your computer uses binary measurement (base 2) whereas most people, including disc manufacturers use decimal (base 10).

In binary:
A dvd 5 (or Single Layer disc = SL) contains approx 4.38 GB (actually should be labelled GiB for binary).

In decimal:
A dvd 5 contains 4.7 GB.

Both are the same size...nice, eh?
This means the manufacturer's label on your SL discs says 4.7 GB capacity when it is, in fact, only 4.38 GiB according to the computer.
Guess who wins?

So the short answer to your question about using shrink as opposed to Fab...it's not going to make much (...none...JMO), if any difference insofar as the video quality.
You can alter the target size in Fab and thus alter the file size and with shrink you have even greater control with individual title compression function.
But, a full SL disc is still a full SL disc.

Hmmm....

Maybe it's time for the old, geek joke...

There are only 10 types of people in the world. Those who understand binary, and those who don't.

Concert videos sometimes have DTS sound, which requires much more disc space than AC-3/5.1. If your disc has both, use only the AC-3 to preserve bits for the video (and require less compression). If you use quality blank media and burn at reasonable speed you can set DVDFab to the same output size as DVDShrink (4464MB). A blank DVD-5 will hold 4,700,000,000 bytes which equals 4482MB or 4.377GB (figured the way a PC thinks).
