File size increasing almost 10 fold

Hello,

This is my firs time using DVD architect and im just trying to burn an MP4 file onto a DVD.

The MP4 file is 2.7 gigs and once i put it in DVD architect it turns into something like 16 gigs and the disc spaced used says it'll be 17.4 gigs total.

what gives?

That's the uncompressed data size.
Since DVDs consist of MPEG-2 video, that is the preferred format to give it.
Then the file size will make more sense.
I suggest you do the render in Vegas, where you will have more control.

Hm, actually, I suspect we're looking at a video file that is way too long too be on one DVD. Given how compressed MP4s generally are and the relatively low bitrate usually used for them, I'm guessing this is a whole lot of video for you to reach a 2.7GB MP4. DVD Architect is then taking that MP4 and re-encoding it (as it should) to MPEG-2 at a DVD compliant bitrate (by default, 8Mbps).

How long is this video? Generally speaking, you should expect to get no more than 2 hours on a DVD. You can get more, but not at anywhere near 8Mbps.
