Increased file size when adding movie media

zidanematthew wrote on 5/3/2011, 8:11 AM
I measured out mathematically how much space 50 videos would be on a 4.5 gig disc and they would (should) all have fit on the disc. But I put in a 105 MB - 8:05 minute video media into the DVD Architect product and it says I just added 587 MB worth of data into the disc when I clearly didn't, it should have been roughly 105 MB! So after 6 videos, I'm at 5.9 GB, above my discs capacity to burn and I'm not even at 700 MB or past 30 minutes! What gives? How do commercial companies fit such large amount of movie data onto a DVD when I can't? Please help!
I'm using DVD Architect 5.0 Build 128.

Are the video files you are importing already DVDA ready MPEG2 files?

Short answer:
-- Prepare your DVD folder in Architect ignoring the message, and see where it comes in. You are seeing unpacked sizes since you did not import compliant MPEG-2.
-- Use a bitrate calculator http://www.videohelp.com/calc.htm
4.5 GB of video will not fit on a DVD5 disc.

No. They are WMV files, because they exported to small sizes, which is what I wanted. How do I get MPEG2 to be DVDA ready?

A Video DVD has to be MPEG2 files. The WMV files will be converted and DVDA is probably giving you an estimate of the final converted size.

You should create the MPEG2 files using the templates in your editing program.

ah, so basically convert them to MPEG2 files and all should be resolved? I'll try that.

well that didn't work. I use Any Video Converter and changed them all to MPEG-2, this still didn't solve my problem. They still register as 500 mb over their actual size. Does it need to be saved somehow special? Or with a specific program for it to recognize its actual size? Or is there an option in DVD Architect to analyze each movie in turn to get its actual size?

1) Render your files to COMPLIANT MPEG-2 using DVD Architect template in Vegas.
2) Render your audio using a DVD AC3 template in Vegas.
3) Use a bitrate calculator to give the correct rendering bitrate.
4) I the DVD Architect estimate is too large, go ahead and Prepare the DVD folders anyway. Then re-open the project and it should report the correct size.
5) Really, that's all there is to it.

heh, well its either 105 mb from another converter or 347 mb from Vegas compliant MPEG-II. So its clear this has to be split up across two DVDs instead of one like it mathematically should have worked. Thanks anyway.

347MB will fit easily on a DVD5.

You need to begin to understand a simple mathematical concept:

Bitrate x Time = File Size

A bitrate calculator will save you the work of doing the computation yourself and give the average bitrate you must use in Vegas to give you the proper file size for ingestion into DVD Architect. Anyway, that's how it works for the rest of us. Best of luck!

You can put almost any length video on a DVD - just lower the bitrate.

I had a client who had me put ten hours on a single DVD-5. I don't recall the bitrate, but I do remember that it looked like crap. (In reality, it was good enough for him to review and make some editing selections without swapping discs).

How do you change the render bit-rate in Vegas Pro? And how do you determine the bit rate to result in the right MPEG2 file size?
