Two DVD's from one project.

I am making DVD's of my 8mm tapes (family videos), which are two hours long. So I realize that I have to burn half of the project to a DVD, then the other half.
Here's the question........The first disc (disk 1)will have a main menu (and possibly submenus) with buttons to link to individual chapters on disc 1, and a separate "menu" page with non linked buttons (or thumbnails) as a directory of the chapters that are going to be on disk 2. Then disc 2 needs it's own menu with linked button to the different chapters. So my project in Vegas is completed and rendered, so do I just set the "Set In Point" and "Set Out Point" for each half and build menus for each half? or can I build the menus all at once before I burn the two separate discs?

I hope that this is written so that you can understand what I mean...... : )
(a little unsure if I am sure what I mean......duh)

Please clarify: Is the total project 2 hours?

If so, you can get it all on one disc.

If the project over two hours and rendered as one Mpeg2 file?

If so, setting in and out points will not change the fact that DVDA will use the whole file unless you want to recompress it again.

Yes, The rendered project is 1:56:51:00. And the size is 5.7gb
That is without rendering the audio yet, but no menus have been made, and there may be some background music on the menus.
So how can that fit onto one disk without further compression, and if compessed to fit, won't the quality suffer?

Maybe I misunderstand the set in & out points, but I thought that DVDA would only burn the area between the (set)"in" & "out" points.

Is it 5.7gb as reported by DVDA or is it actually 5.7gb? DVDA overestimates.

If it's actually 5.7gb, what bitrate did you use? With VBR with an average of 6Mb/sec and max of 8Mb/sec, you should be able to get two hours on a DVD without losing a lot of quality.

Not if it's an MPEG.

Yes it is MPEG2, and the rendering in Vegas5 was
MainConcept MPEG2
DVD NTSC
VBR, Max 8Mbs, Avg6Mbs

The actual file is 5,435,212KB (according to explorer).

I didn't know when I rendered it that I should have used
DVD Architect NTSC Video Stream, and then rendered the audio separately.
What format is best for the audio, keeping in mind that the audio is home videos?

AC-3

To GaryKleiner and bStro,
I have the problem also about two hours Mpeg2 to fit in one disc.
The one mpeg2 is about 47 min and the second one is 57 min (5.3 GB).
My DVDR disc only 4.7 GB, let's me know how can i fit that two mpeg2 in one disc or how about of recompress it again? (where i want to setting? bitrate or something else?)

Not if it's an MPEG. ??
What format is used where the Set in & Set out points are used?

Is MPEG-2 the preferred format to render to? (for DVD's to be played in DVD players on TV)

I re-rendered the avi video as MainConcept MPEG-2 and the format is DVD Architect video stream, then I rendered the audio as AC-3
Still the project with menus shows under optimize as 5,670.9MB. So what would you suggest, that I try to burn it and see if it completes??

I didn't say that In / Out points aren't used with MPEG2. They do what they're supposed to -- they indicate where your movie should start and where it should stop.

But, in the case of an MPEG2, they will not trim that movie. The movie will start and stop where you want, but all of it will still be put on the disc, because DVDA will not edit the file. In most programs, editing an MPEG2 file requires re-encoding the whole thing, which takes a looooooong time. Even if you try to do this with an MPEG2 in Vegas, it's going to take a long time and you're going to lose quality.

On the other hand, if you use an AVI file, and set the In / Out points, DVDA will actually trim the file because an AVI has to be encoded into an MPEG2 anyhow.

So what would you suggest, that I try to burn it and see if it completes??

Not burn, just prepare. When you click the Make DVD button, you get three options:

Prepare DVD

Choose the first one and select a folder for DVDA to put your DVD files. This will create all your VOB, IFO and BUP files, but will not put them on a disc. After it's done, go into Windows Explorer, find the directory that you selected in the Prepare stage, and see how much space the files really use up. (DVDA's estimate is almost always wrong.) The simplest thing to do is to right-click on the VIDEO_TS folder and choose Properties. See what it says next to Size On Disk. If that's less than 4.7GB, go back to DVDA, click Make DVD, and choose Burn DVD.

If it's more than 4.7GB, you can try DVD Shrink to adjust your prepared files.

Interesting........I wonder why they don't explain that in the manual.........?
Thanks for the info it is very helpful.

OK, so after completeing the DVDA project the estimated size in optimize was 5,679MB and the VIDEO_TS size is 5.16GB (5,547,517,952bytes) and it wouldn't burn, so my original question was answered with the explaination of set in & set out as not being options.

My next question is, if the Vegas5 project has been rendered, can I simply cut the rendered project in half without losing any quality? then make two discs? OR do I need to cut the un-rendered project in half and re-render each half?

Also on this over-estimating thing that DVDA does......does the program overestimate consistenly enough so that one would know that at some point (size) a project would or wouldn't fit on one disk?

Hmn. Y'know, I just checked the manual, and it does indeed say "You can set in and out points if you don't want to burn your entire video to DVD. When preparing the DVD, the software will trim the video to include only the portion between these points." No mention of whether this is pertains to MPEG2 or only formats that have to be encoded.

I wonder if, perhaps, changing the video's settings (in the Optimize DVD window) to force DVDA to recompress it would also force it to trim the video? Of course, in that case, you may as well trim the video in Vegas and render to a new file.

My next question is, if the Vegas5 project has been rendered, can I simply cut the rendered project in half without losing any quality?

Not with Vegas. You'll lose a bit of quality and it will take a long time. I recommend either one of the products from Womble for editing MPEG2 files. Personally, I think you should go with the DVD Shrink plan. Your project is small enough that it could fit on one disc, you just have to "squeeze" it a little.

does the program overestimate consistenly enough so that one would know that at some point (size) a project would or wouldn't fit on one disk?

Not sure. I've been meaning to do some tests and record the results, but haven't gotten around to it yet. I'm usually okay as long as the estimate is around 5GB or under.

I am trying the prepare DVD right now, after setting the in & outs for only half the project. With the out point set half way, if I preview the project there is no links to the buttons on my menus for any of the video from the out point to the end............I'll know here in a few.

As far as optimizer force fitting the project to disk I have tried that & it will not, says too much data. It does say that It may work if I let it re-render, but i am afraid of the quality loss, so I don't have a problem just cutting my original project in half in Vegas, then re-rendering each half, then burning each half in DVDA.

OK, nope the test did not work, after preparing the DVD (with the set out point at the half way point in the project) it stil says the project is too large & gives me the choice to continue or cancel, I tried continue & it spit my DVD out of the drive and said "sorry, no can do"

Back to the drawing board......... : )

Hey, how do you copy and paste quotes IN ITALICS from other posts?? I can't find any option for that and when I try the traditional CTRL+I it affects my browser window, and while I'm asking, how do you put links in posts??
