The size goes up 2 gig

puttes wrote on 9/6/2004, 4:00 AM
Having MPEG2 file of 4.2 gig containing 1 hour 40 min.After copying the file to DVDA1 the file all of a sudden is 6.6 gig and to large to fit on a disc.
So,do I have to fit it on two discs ( very unconvenient) or shall i recompress the file?If so, the quality would get to bad.
On the DVD disc it claims it will contain up to two hours and as it is allready rendered it shouldnt matter if there are a few trasitions or text ( which there is little of - a normal wedding production).
Other softwares can easily put on two hours on a disc. Is this not possible with Vegas any more?

Any ideas?

If the MPEG-2 file is 4.2 GB, then it shouldn't expand to 6.6 GB, unless you have "used" it more than once in your DVDA project, or you have a HUGE audio file assocated with it, or unless you have created extensive menus. Try starting a new DVDA project, put the MPEG2 file in the project and then immediately go to File->Optimize and report on the information provided there. This dialog will tell how big DVDA thinks each part of your project is, and whether each part needs to be recompressed. Obviously, you do not want to recompress any MPEG2 files, if you can help it.

Exactly what I have done. Despite this the file expands up 2 gig.The audiofile is nothing to mention. I guess then the only thing to do is to reinstall the DVDA1.What else to do?

Where'd you get the original mpeg2 file from? Darryl

Dude:

I'm not as experienced as the guys here, however it's my understanding that 1 hr 20 mins max is what you can fit on a DVD at a bit rate CBR of 8000.

To get the extra 20 mins you have 2 options.

1/. Render to AVI then let DVDA render the MPEG2 with a lower bitrate, ensuring it will fit on the DVD. There is a button called 'fit to disc' (From Memory, I'm not at my Vegas PC) that will do this for you.

2/. Find a bitrate table and work out what bitrate Vegas will need to render the MPEG for it to fit on.

JetDV has a table on his site, apparently there are others around.

Good Luck.

I have a feeling that we are closing in to the problem.To change the bit rate would be the right thng to do,however the fit to disc buttom I have never found though, ( I have DVDA1). But the question is if the quality is sustained if I lower the bit rate from 8000 to 5000?
But why does the file grow 2 gig while moving to DVDA1?Grazie and I have scrathced our heads in agony to find out why the heck the file that rendered in vegas to MPEG2 in as 4.4 gig all of a sudden becomes 6.6 gig.

DVDA1 is really, really bad about project size estimates. DVDA2 is better, but still not perfect.

Obviously you will lose some quality if you lower your average bit rate from 8000 to 5000. There's currently nothing you can do about that unless you want to go to multiple disks, by a more expensive encoder, or go dual layer.

My suggestion would be to simply try doing a Prepare on the project and add up the sizes of the VOB and IFO files in the video_ts folder. If windows says all of the files together are less than 4.37GB, then you're good to go.

One other thing - I don't think DVDA1 has a "fit to disk" option.

Scott, I spent sometime with Puttes on the telephone yesterday. And yes it would appear DVDA1 is "displaying" a "fluffed" up file. However, Puttes can't get beyond the accept burn part . . I don't have DVDA1 .. I have DVDA2 so I was as usefuo as a Chocolate TEAPOT!

Puttes, you gotta the latest buiold of DVDA1? It is up to DVDA1d build 230 now ? I don't know if it will make ANY difference at all but ere's the link anyway . .. have a read too:

The fluffed-up 2gig is really stumped me . .. shame you don't have a cheapo DVD buring s/w . .just to confirm it is or isn't DVDA1 - yeah?

Sorry mate,

Grazie

I will try to do that.I made a trial burn in 5000 bitrate and the result wasnt too bad really.I think I can sleep well tonight.Happy birthday Grazie.I have wired over some cash

Nah! Not necessary . . . I'm glad you've got a "compromise" . . I guess that's what we all liev with if we haven't got the resurces fo the Hollywood studios - yeah?

Thanks for the B-Day wishes . ..

Grazie

i'm having a similar problem. i brought over an .avi from vegas to dvda1 and burned a lot of dvd's at great quality. now i'm trying to take that and bring it into dvda2 and burn a dvd but it told me that the file was something like 7 gigs and needs to be recompressed. i've only used dvda2 for a big project once and the quality was terrible and i think it might have something to do with estimating the size of the dvd incorrectly and compressing the file more than it should. thanks for any future help.

Have you tried to lower the bit rate so the estimated size goes down to under 100%?If you try to burn a small part in 5000 and see if the quality is acceptable if not I feel really sorry for you.
Really ennoying that the size fluffs up like that.You could really expect somehing more from the s/w
