dvd compression
We have a 4 disc dvd 9 replication project that will press on dvd9.
All discs are under 4 hours of content except for the last disc which has
5 hours. Can we get away with compressing this last dvd at acceptable quality?Thanks in advance.

There are two unkowns here.
1>What is “acceptable”? This depends on the use and audience of the disc.
2>What type of content? If it is a talking head, the same compression settings will result in a smaller file size than if the content is fast action.
For instance, on my Vegas and DVDA instructional videos, about 75% of them are screen shots which have very little change from frame to frame. For that material, I have no problem getting over two and a half hours onto one, single layer, DVD.

thanks gary..good points
I suppose we are most concerned about loss that would place quality somewhere close to VHS..if it were a scale of 1-10 1=vhs 10= dvd we’d like stay in the 7-9 range for the one disc.
Motion varies, but for the most part, medium – slow would best describe the pace, panning, zooming etc.
WOuld a 85% compression be around the target were after?

You’ll just have to compress so that the files barely fit on the disc and see if the quality is acceptable to you.
