DVD authoring questions

[nodakskip]

Ok. I have a file in two formats.

MPEG1 at 3.97 gigs
AVI at over 9 gigs

The movie is one hour and 30 min.

I have tried to place it on a DVDr using Roxio(not sure version) and it works fine till it says I have not enough space on the dvdr. The one I am using is 4.7. However the pc says that the 3.97 file comes to between 3.5 gigs and 5.4 gigs after it is encoded by Roxio, so it has not enough space on the dvdr.

Is there a way to make it work on a 4.7 gig dvdr or would I have to go online and buy a single higher space dvdr like a dual layer 8.5?

Not sure what the dvd burner is but its in a Sony Vaio desktop pc.

I have not tried it as the avi format to dvdr yet, I assumed it wouldnt work either. Does AVi work as dvd video?

No, avi is not playable on most DVD players. It is possible though to get one that does.

Your mpeg1 may be DVD compatible even if Roxio insists on re-encoding.

Roxio is crap.

Test your mpeg with Gspot and post the results if you want to know if it is DVD compliant.

Regarding your avi, here's a guide.

First it seems I made a mistake. Its in MPEG2 not one. I have Vegas Video 4 and it only lets me us MPEG1 for vcds. I tried it out on my computers 'PowerDVD' player and it played great.

I am doing a re-encoding with Vegas as a MPEG2 with the video quality set a bit lower then the highest. Dont think it will cut much down on the file size.

The dvd burner computer also has the Vaio 'Click to dvd' program that hasent worked in a while.

And also didnt know I had it, but would a program like Dvd Architect 1.0 that I think is with Vegas Video, could that create the dvd? I havent used it at all. I just found out I had it. Are there guides for it?

I would reencode the avi from vegas in two parts

1. video stream VBR min 0, max 9400, avg 5900
2. audio stream AC3 2 channel stereo

The following guide should help you turn these files into a DVD.

VCD has a set standard and one of them is that it's mpg1, see to the right under the What Is section for VCD and DVD specs. For DVD use MPEG2, it gives you flexibility. You can use the VCD standard but as I said it's a set standard that can't be altered.

Yes it will, by the generic term lower quality what your doing is lowering the bitrate. For example using a file with settings such as 8000 kbps CBR (constant bit rate) with pcm audio will take up an entire DVD. On the low end doing a test I was able to fit about 20 hours using 434 kbps vbr (variable bit rate) with ac3 audio, all within the DVD specs. Wasn't worth anything but I could do it.

Well I have reencoded the movie file with only one minor change and its done a lot of good. I took the audio sample rate from 48,000 to 44,100 and its cut the size from almost 4 gigs to 2.87 gigs.

I will still try to make a menu on DVD Architect. But when a MPEG2 video even formated for dvd is used, will the dvd seem bad at all?(jumpy or stalling?) Would a MPEG 3 or 4 be much better? Is there a cheap program to encode to MPEG 3 or 4?

DVD video is mpeg2 mainly (mpeg1 is also valid). mpeg3 and 4 is out of the question. DVD audio is AC3 or LPCM or MP2 and it should be at 48kHz sample rate.

But will the audio still play fine? It does in my tests on Dvd Architect 1.0 and PowerDVD.

Depends on your player - software players aren't very good test benches, as they play pretty much everything, while hardware players vary from almost as tolerant as their software counterpart to very picky. Using out of specs audio will only make your product less likely to play, while giving you no advantage at all.
