Movie Factory: .mpg size that'll fit on DVD-R?

[rw88]

I am authoring and burning to DVD-R with Movie Factory, and I'd like to optimize my quality. A ~2 GB .mpg (made using a 3000 bitrate) was authored and burned without mishap to my ~4.7 GB DVD-R... no surprise there.

Now when I increase my bitrate to 6000 to make the .mpg, it increases the .mpg to about 3.5 GB, still less than the DVD-R capacity. When I go to burn this file, though, Movie Factory tells me it won't fit! So there's an inequity in the file sizes here...

Anyone happen to know what the max size is for mpeg2 files that will burn successfully to DVD-R using Movie Factory?

Thanks,

Rich

I am using dvd movie factory and burn 4.2 gig images all the time
Lets check a few things
1. What kinda audio is in your mpeg ?
2. is movie factory rencdoing your file ?
3. is it saying not enough disk space on the dvd or your hd as it will tell you both.
4. file system is an issue if you are breaching 4070mb's fat 32 wont allow it but ntfs will .
if it is rencoding make sure it isnt using pcm aduio which takes up way more space and use something like dvd dazzle to check that your image is compliant .

I'll have to check those parameters out tonight; as far as I know, Movie Factory isn't reencoding anything... I'm just capturing my video in Studio 7, creating the mpeg-2 using a given bitrate, and then using that .mpg as the source for movie factory's "point and click" authoring.

Movie Factory is telling me at the final step just prior to burning that the DVD doesn't have enough space.

I am using NTFS.

I'll post again with the audio info; is there a quick way to see what type of audio is carried in an .mpg?

Thanks,

Rich

A DVD only holds ~4.3GB (the 4.7 figure is technically a lie, since it's measuring "billions of bytes" rather than GigaBytes).

Regardless of the type of audio included in the video, moviefactory will burn it to DVD as PCM (uncompressed) audio, so many authoring programs DO re-encode the audio (or reject it) if you had it encoded as mepg audio. More advanced authoring programs allow ac3 audio, but you'd know if you had made the audio like that (I've heard reports that muxing ac3 audio into the mpeg lets moviefactory use it). BTW this is from an NTSC perspective; if you're on european PAL you can use mpeg audio with DVDs.

PCM audio takes about 10MB per minute, so if you have about 90 minutes of video (approximate given your filesize and bitrate) you'll end up with about 900MB of audio. Add it all up and that leaves less than 3.4GB for video. Just lower your bitrate to about 5500 and try again.
