Blankd DVD-R's, confused about the amount you can fit on !

[Panther96]

Just like to say, I haven't got a DVD writer, but I'm interested to know more, and I've read some posts which say that blank DVD-R's have a capacity of about 2 hours.

Is this true, only the manual for my Phillips DVD-622, says that a single sided, single layer DVD will hold 2hrs 30mins

A blank DVD holds 4.3Gb of data (where 1 Gb = 1024 Mb = 1024Kb).

The length of video you can fit within this space is limited only by the bitrate you encode. Higher bitrate means less video and vice versa.

VCD compliant video is als DVD compliant (except audio must be at 48khz, not 44.1). This uses a constant bitrate of 1150kb/s. Do the math.

Many commercial DVD's are encoded with an average bitrate around the 5000 to 6000kb/s bitrate. Again, do the math.

Hope this helps

There are also several valid resolutions for DVDs. If you encode at 352x480 with a CBR around 2700, you can get over 3 1/2 hours with fairly good quality. I am able to place 4 1-hour TV episodes and 1 half-hour episode on one DVD after editing out the commercials.

I have put almost 6 hours of video on a DVD-R with very high quality results using 2 pass VBR. It takes longer to encode but you can pull off a lot!

Just to help with the math on dvd sizes, they differ from your standard 1024mb = 1gb.

* = A single layer DVD(DVD-5) fits 4 700 000 000 bytes and that is 4.37 "computer" gigabytes where 1 kilobyte is 1024 bytes (4 700 000 000 / 1024 / 1024 / 1024 = 4.37GB). So why does it says 4.7 GB on the DVDRs? Because they are not using "computer" gigabytes, they use standard "kilo" where 1 kilobyte is 1000 bytes. Also note that it does not exist any dual layer DVDrs(DVD-9) which can fit 9.4 BB(8.7GB) which most commercial DVDs are using today.

also KDVD has a great template for re-encoding dvd's to fit a 2hr movie on a single DVD. Used it on Bagger Vance with dolby surround turned out to be around 3gb with no drop in picture. I've been splitting most of my movies, but never again.

look under DVD 1:1 copy

There is a post in this forum I think his name was blackout about ripping DVD manual, or the process he uses, others have posted their suggestions. Read it and you'll get a good idea on DVD copying.
