Time for Assets on DVD seems rather small...
July 18, 2008 01:59PM
I am creating a multi-buttoned presentation coming out
of Final Cut Pro set to DV editing quality and this looks nice going into
DVD Studio.

I have loaded 5 tracks so into the main window whilst watching the
total for the SD DVD total space meter on the top right hand side
(which goes from green to red)

My five tracks times are in minutes
1) 5:16
2) 8:24
3) 23:09
4) 11:47
5) 13:49


So this is roughly 61 minutes and already the my meter is calling
for 4.4 G used space!

The size of the QT files

1) 1.12G
2) 1.78G
3) 4.91G
4) 2.5G
5) 2.93G

Anyhow I thought you could get 2 hours of video on a DVD????

Am I doing something quite wrong?

Thanks in advance

What encode bit-rate did you use ? Did you run these through Compressor?

I have easily gotten 2.5 hrs of reasonably good content on a DVD-5, but my bit rate had to be LOW. Approximately 3.5 Mbps to 5.0 Mbps.

That bit rate determines the total size of each MPEG-2 file. also the total size depends on the audio file used as well. Use AC3 instead of .aiff to reduce total size.

No, these are the direct output files from Final Cut Pro.
In order to fit more on the DVD; I used Sorenson Squeeze to
mpeg2 output and the quality is good at 6Mps.
(We don't use compressor as we had a bad experience with the
quality with R2)

It seems that DVD Studio 4 requires an mpeg stream rather than
a QT stream for optimum results.

Next time I will make sure I compress my assets into mpeg2 with Sorenson
prior to bringing into DVDSP.

Thanks

Of course - a .mov file is Quicktime

Absolutely, requires MPEG-2 rather than .mov

The fact that you used 6 Mbps will give you a larger sized fie and therefore takes up more space on the disc. Another feature of the audio, get it into Dolby AC3 rather than the default .aiff.
