Authoring Problem with MF2 revisited

[Wetling]

Okay, I'm trying to convert a 43 minute AVI file to VCD format (MPEG1) so I can burn it to a DVD.

I start by using VirtualDub to extract the audio and HeadAC3he to convert it from AC3 to WAV.

Then I open the original AVI and the new WAV in TMPGEnc and tell them to become an MPEG file.

The result of this is that I have a 43 minute MPEG file that appears to be about 430MB (as expected). However, when I add the new MPEG file to MF2's burning que, it tells me the video file is going to take up between 1 and 2GBs (as opposed to 430MB).

Why is this? What can I do to fix it?

Thanks

Because it is a non-compliant file. If you started a DVD project then the MPG must be Mpeg2 and since a VCD is an Mpeg1, it means that MF2 is about to convert the file to DVD compliancy, a much larger output.

MF2 will accept the VCD frame size, frame rate and audio, and thus keep the file size the same (just set these in the project properties option) but it will convert the video to Mpeg2.

Okay, I don't think that's right explantion. Here's why, when I capture 43 minutes of video and encode it as MPEG1 (as opposed to converting from AVI w/ ac3), it is a ~430MB file that MF2 doesn't try to make bigger (it stays about 430MB when burned).

Please see this tutorial for details on how to put VCDs on a DVD with no reconverting of video.

OK - it seems I missed the point to your problem.

There is one thing you can check though (if you haven't already checked), on the last screen when you are setting up the burn instructions, check the 'Output Advanced Settings' and make sure the 'Include personal folder to disk' is not ticked. This can add gigabytes to the final burn.
