I have a LARGE archive of videos that I am trying to burn to DVDs from tape. I don't care as much about quality as I do getting them on a small number of DVDs.
The story so far:
I have captured them using an old DAZZLE video capture box to digitize the video and had to use MOVIESTAR (the dazzle software for the capture box) to covert to VCD files.
I ran into the dreaded "covert got some problems" error and was able to overcome that by rendering the files into new VCD files using Roxio video wave 7. (I don't know why that makes a difference, but about 1/3 of the files needed this to work)
Now I have 8 hours of VCD files that MF3 reports will burn into 4.2 Gigs of DVD video using a constant video compression of 800. Yet when I burn it as a ISO file I get a 5.2 Gig file. So I tried a constant video compression of 650 and MF3 shows that it will take 3.8 Gigs but when I burn the ISO file it still is 5.2 Gigs.
Could anyone explain why the ISO file size seems to have no barring on the indicated size of the file in MF3 or the amount of compression.
Thanks,
JCB
Judging File Sizes in MF3
udate patch
Why don't you try updating its latest patch from Ulead's website? It might help you with its file size problem. ^_^

I don't think you can go that low on the data rate. All my Ulead programs tell me I have to have a minimum data rate of 1775 kbps for DVD. So it should not let you enter in rates lower than that. What's probably happening is MF3 is using the minimum DVD data rate and that's why you file is coming out bigger than you expected.

This should work for what your trying to do.
Hit the "GEAR" Icon and UNCHECK "Do Not Convert Compliant MPEG files".
Hit the "Change MPEG Settings"
Choose "Customize"
Make the following your template: These are for NTSC settings and the smallest framesizes allowed for the dvd spec.
GENERAL TAB:
Aspect Ratio 4:3
FrameSize = 352x240
COMPRESSION TAB:
Quality = 80
Videodata rate = Constant 1150
Audio format = MPEG audio at 224kbs or Dolby at 224kbs
After you come back to the timeline the total size should now be smaller.
If the total size isn't smaller then lower the video_bit_rate to 1000.
Go lower on the video_bit_rate if needed to fit the project.
As an experiment change the audio to LPCM and watch the project size increase. This will give you an idea of the settings. Change the audio back of course.
The lowest you can go is around 500kbs (poor quality). Don't forget any menu's will add to the total project.
Do not JOIN the videos, keep them separate if possible.
A VCD bit-rate is 1150kbs so try to stay at least 1000kbs for quality.
If PAL dvd format use the lowest PAL framesize in the drop-down selection for frame-size.
Hope this helps,

Thanks for the info.
Thank you all for the responces, what I have found so far.
1. I am up to date on all of the patches, but you are right, that is always the first step when there is a problem.
2. The recomendation to change the settings to
>Aspect Ratio 4:3
>FrameSize = 352x240
>Quality = 80
>Videodata rate = Constant 1150
>Audio format = MPEG audio at 224kbs or Dolby at 224kbs
does change the tab at the bottom, but when I would create the ISO file it would still be at 5.2 Gigs regardless of what the bar says.
3. I tried changing the frame size to 780 x 480 and you are right, it will only let me go as low as 1775. Then when I burned the file it came out at 5.2 Gigs. This may be what is happening, I'll have to experiment a bit more and check it out. (the problem of course is that to burn the file takes about 5 - 6 hours, so it may be a while before I have the time to set it up and let it run all night)
My next question then is probably not answerable, Why would a company put out a product with a Framesize that will go as low as 352 x 240 and video data rate that can go as low as 434 if it then won't use those settings? Is there a programing God I have offended somewhere that is now playing with my sanity?!?
Thanks,
JCB

You can encode a video with those settings because they are dvd compliant settings. DVD Desktop recorders use those settings for the 8
hour mode. There is also a need for those settings even though the
video isn't very good. Depends on what you are doing. Surveillance cameras etc.
But you know that already.
Maybe one or some of the videos are longer or corrupted and exceed 8 hours.
Hard to say.
In the output stage click on 'Options" and make sure nothing extra is being added to the DVD.
Also disable "Motion Menus".
Try creating a dvd folder instead and tally up the total of the folder after it's created.
8 hours is alot of video.
Good luck with it.
