DVD Architect Problem

[duraysteeus]

Hey Everyone,

Some of you already have seen my posts as I've been working with Sony Vegas and DVD Architect.

I had a brand new project started in DVD Architect and I imported an MPEG-2 movie that was 1 hour and 28 minutes long with a size of 3.93 GB. However, as soon as I imported it, DVD Architect said that I used 4.5 GB of disc space. I don't understand. I didn't have any moving menus or anything. It was just that one movie. Why is it telling me that I've used up almost all of my space when the MPEG-2 file is only 1 hour and 28 minutes and only 3.93 GB?

A DVD isn't really 4.7G size. You won't be able to fit that much more than 3.93G of data on it. No real mystery here.

I'm guessing that the source file was either MPEG or AC3 audio and the DVD Architect Studio which only supports PCM (uncompressed) audio so the file size grew to account for the compressed audio getting expanded. If you paid hundreds of dollars for it then you may have a knob switched wrong that does not produce ACE audio.

This is my biggest complaint about the product (not to mention the horrible artifacts that it produces when doing a pan and zoom slide show). I wish I only paid $10 for this software and not $60. The free Ulead Movie Factory 4 software that came with my DVD writer makes way better looking video.

What are you talking about? DVDA supports AC3, MP2, PCM, and maybe DTS!
I know, I've successfully done a number of national education titles with AC3 as my audio in DVDA. And if you bought Vegas+DVDA together, the AC3 compressor comes free.

You set the preferences for the "default" expected stream properties--like MPEG2/720x480/29.97fps/8.00Mbps and AC3/2.0ch/192kbps.
When you go to "Make Disc", it'll tell you if you'r compliant with that expected target. If not, it'll (usually) give you the option of leaving as-is or recompressing. I never recompress, unless I've grossly miscalculated my bitbuget, and then I would recompress directly from the original master, using TMPGEnc or Mainconcept, etc. However, the "gauge" is really just an estimate, which won't be clarified until you get to the "Make Disc" stage.

If your encoder has good rate control to begin with and you give your bitrate calc a good 5-10% buffer, you should be within your boundaries.

Now, assuming your calc was correct--

1hr28min = 88 min. = 5280sec.

3.93GB = 4024.32MB = 32194.56Mb

So your bitrate should AVG <6.1Mbps.

If that's not what you set it at, maybe what your OS is saying re: your filesize on HD isn't correct.

Plus, you'll have 123.75MB used up for AC3 2.0ch at 192kbps.
With the 5% buffer, that comes to 4355.4735MB, which is getting close to the 4474MB limit.

I think there's a mixup -- seems like one person is talking about DVD Architect (full version), while the other is talking about Vegas MovieStudio + DVD Architect Studio (scaled down version).

What did you use to render the original MPEG file? What were the settings?
