Hey guys, I have a few questions related to encoding and burning. Since they are both linked together, I'll just post it here.
First, I have a few 2 and a half hour AVI files. I need to burn them to DVD - which I have done before with no problem, usually they are under 1 GiB or so in size. However, these are HD AVIs, and are about 2.5 to 3 GiB each. Once I make my DVD, they end up being about 6 GiBs, and I only have single layer DVDs. I'd rather not use 2 DVDs when I could use one, though. Here's the specs for the video file:
I just need to know how I can re-encode this video file so that I will be able to burn to a single layer DVD.
Thanks!
WAH!!

What program are you using?
99% of all problems are between the computer and the chair.

Well I run linux, so I use Avidemux for my video encoding, and then some different programs for my dvd authoring- mainly mandvd or qdvdauthor. Avidemux is great - basically I just need to know how to re encode the video so it will be a 2.5 hr video with a smaller file size.
WAH!!

The size of the source file makes no difference when converting to DVD, only the running time matters. Your are doing something wrong, 2.5 hours should easily fit on a DVD. You need to set the video bitrate in what ever program you use to about 3500 - 3600kb/s.

??? 704X384 is hardly 'High Def'. That's not even 480i NTSC...

No it's not is it... and that could be the problem.. try making it 720x576 first,(or whatever your native dvd resolution/size is) or set the authoring program dvd.xml file to add black bars up to xxxx size requirement.
Give DeVeDe and todisk a try.. qdvdauthor imho has a lot of bugs.. or use rav dvd author without the pretties... One other thing.. if you are trying to add a menu with qdvdauthor RTFM and see that the background is very very specific...

Well I admit while I have had some experience encoding video, (mainly for my psp), I am really hitting some walls with making dvds.
I just know that the picture quality of the video looks high definition, regardless of screen resolution. Some snapshots so you see what I mean-
Yes, it is Game One of the World Series, Phillies vs. Rays.
I use ManDVD for making my dvds. Usually I load the videos, then make a simple menu (background png, text) and encode and create the structure. Of course it is all automated so I don't get to choose very many settings as for the technical parts go.
When I did this, the first game, which is 2.7 GB and 2.5 hours, came out to be 6.7 GB or so. I need it to fit on a single layer dvd, so I surmise the input video needs to be re-encoded into a smaller AVI. The video settings are
2:39:9
704x384
XVID MPEG-4 Codec
Audio...
AC-3, 5.1 channel
448kbps
If anyone knows exactly how to re encode this to a smaller size, by lowering the video and audio quality, or compression, that would be great!
WAH!!

Hello - see MysticE's post above. As he says, the size of the avi
is generally irrelevant (both in GB and resolution) because the
DVD encoder should scale it (by changing the res and bit-rate) to make
it fit the DVD standard. The bit-rate chosen by the program should take
into account the running length of the source file and your chosen
medium (presumably single layer dvd)
A second note, since the avi already has ac-3 audio, you should be able
to use it as-is, thus fully preserving the sound quality. Only the
video need to be converted . The existing audio can be muxed in.

Yeah what you say makes sense - that's why I was a little shocked when it produced a dvd almost 3 times the input size. I will play around with it some more and see what happens.
WAH!!

Ahhh.. now I get what is happening... qdvdauthor by default tries to make a dvd9 set.. I stopped using it because of other annoying bugs.. in the config file there should be a "target=" string where you can set the maximum output size. see http://dvdshrink.sourceforge.net/dvdshrink.html for the kind of things you are looking at...
Make life easy and use DeVeDe.. and ensure you have the target adjusted for 4.7 dvd.. That's the easy way instead of xxxxx.. err.. messing around with buggy apps.
You are using n00buntu.. it's in the repositories.. also look at debian-multimedia homepage for extra codecs and things of interest.
Takes a linux multimedia dev to help a linux user with awkward little things like this. Not your fault.. it's a mistake by the qdvdauthor people :)

Yeah...I'm relatively new to ubuntu and am still learning things.
I used DeVeDe before, but it doesn't offer very good menu support. Even though I didn't like ManDVD, I used it, even though it was crap. There's a new version of DVDStyler out with AVI support! I'm trying it out now. If all else fails, I will go to devede. Thanks for the help guys
WAH!!

dvdstyler will confuse you.. Problem with qdvdauthor is the unfinished nature of the menu support.
I posted a huge heap of stuff on afterdark about menu building, but the dvdauthor wiki seems to have most of the information you will need. I'm not going to start on about making buttons and transparancies and linking the action into the (I make animated) menus and how to get at multiple subtitles and different views and directly address the dvd player registers for special functions like on screen interactive features... even though I know how to do all of that.
Look more closely at dvdauthor.. it's very powerful because you have total control of every aspect of the build through the dvd.xml file.. all you don't have is a pretty little window with buttons to click.. nice and pure. It will output an iso which you can play with vlc to check everything is working a it should before you burn... No "one click for noobs" solutions on linux.. devede and todisk are about the closest.... But surely you chose linux because it puts you in control of your tools, not because it is pretty and makes all your decisions for you?.. hold on.. ubuntu.. lindows in disguise.
