Need advise on creating a DVD

I have created a 25 minute VSP (VS 11 Plus). I utilized several tool to create content. One such tool, BluffTitler created several very large AVI files for me.

I created them uncompressed (don't ask me why, it just turned out that way). A couple of the files are close to a gig!

Consequently,I have two alternatives. One is to go back into BluffTitler and recreate them with some compressing codec that VS11 may (or may not) like.

Or, I can go ahead and create a huge huge mpg file that will subsequently be input to the Share for the DVD end result.

Now, here is the question. Assuming I go ahead with Option 2 (using the uncompressed input files), how would you recommend I create the DVD (i have a writer that can create double sided, double density I belive).

But if it turns out I have a standard ole writer, what would you do?

Thanks in advance,

Bob

You might think 1 GB AVI is very big. In the scheme of things it might not be. 1 hour of DV-AVI from a MiniDV camcorder comes in at 13 GB and when compressed at relatively high bitrates for excellent DVD quality will still fit onto a normal 4.3 GB DVD disk.

Try it and see what happens.

Great news... thanks for the info.
What would be your Share codec ect of choice for something like this?

You can leave the Titles uncompressed, assuming you will be adding them to your 25-minute video project (are they overlay titles, or are they rolling credits that will add to the end of your video)?

Regardless, you make your calculations based on running time of your final video (NOTE: there are other factors in calculating space requirements in SD-DVD, but in terms of VideoStudio you don't have to worry about things like dvd-selectable audio tracks or multiple video angles in the final burned DVD).

If space is a problem, then you might consider compressing your titles. But hard drives are pretty cheap now...

I think the key thing is that the titles will be compressed by VS when you output to DVD.

You might then free up the 1GB of space on your hard drive by deleting the title if you like, and if you're not going to use it again.

If, on the other hand, you had created a more compressed title, the picture quality of the title on your finished DVD might not have looked as good, but the finished size of the DVD would have been almost exactly the same.

I must admit to no great familiarity with Bluff Titler, but it might well offer a "lossless" compressed format which would be worth trying if you are short of hard drive space.

Earlier versions of VS had problems scaling avi from Bluff Titler - not sure if this is the case with VS11, but it would seem sensible to produce titles with the same resolution as your DVD - e.g. 720 0r 704 x 480 for NTSC, 720 or 704 x 576 PAL, and probably to match the frame rate of 29.97 or 25fps if that is also an option.
