How much video on DVD-9

[mdredmond]

Hi,

Please forgive how basic this question is...

I have need to put five (5 !!) hours of video on DVD9 - this will be pressed or burned or whatever by a duplication house - not a home DVD burner.

The question is, is there any way to get all of this on one DVD? If not, is two realistic?

It is instructional video and quality needs to be decent but not like a movie. Can I save space by perhaps making my picture smaller than whole-screen and putting a solid-color border around it?

Thanks!

According to the dvdrhelp bitrate calculator, you would need to encode you video at approx 3750Kbps to fit 5 hours on a DVD-9. At this low a bitrate you might want to consider using 1/2 D1 resolution.

As this is going to be commercailly produced (pressed) on DVD-9, you shouldn't need 2 disks unless you need lots of high detail high motion scenes.

If i'm not mistaken, a DVD9 (dual layer-single sided) disk can hold about 8500MB of data. If you run that thru a bitrate calculator , you can fit 5 hours of full screen DVD video with 2 channels of audio on a single DVD with a calculated bitrate of 3619kbps.
While this is not the best. This is not bad.
If you can burn DVDs, you can burn one with this bitrate to give you an idea of how its going to look and sound.

Sorry Bugster, didn't mean to post what you have already said....

Awesome - thanks to both of you for the answers. I'll try burning some at that rate and see how it comes out.

Thanks again!

Yes it spossible but youd have to lower the bit rate so quality would suffer

Looks like you were typing at the same time as me. I just hit subit a fraction earlier.

Don't worry about it, happens for often than you would think

A dual layer dvd9 can "only" fit 8140 MB (7.95 GB or 8 540 000 000 bytes)

I have added it to the calculator now

Excellent Baldrick. With Dual layer burners just around the corner thats just what we need.

I would like to know how much you can fit on each layer. Because if you want to have the layer break at a special location you must know how much to fit on each layer. Is it same on both or?

[bugster]

Can't remember exactly where I read it, but I saw one article that said each layer must contain the same amount of data. I.e 1/2 the total data to each layer.

I read the same thing, it is in a thread somewhere on this site. Also might have been a link to one of the manufacturers.

I also just read that, http://www.cdfreaks.com/news/8789

The dual-layer DVD+R specification does not require the entire disc to be recorded. Philips' Driessen said that if one layer of a dual-layer DVD+R has a recorded signal at a particular point on the disc, the other layer must have a matching signal; otherwise, a player may detect an error. For example, if one layer has 4GBs of data recorded, the other layer must have 4GB as well. But he said blank space may be left at the edge of the DVD without any playback problems.
