Reduction Level for DVD-5

[mtobc]

How is this number obtained/calculated?

Reason I ask, I was needing to determine the size of an unmodified dvd(just the video part), that I no longer have. What I do have is the rebuilder.log and the output files from dvd-rebuilder. The only way I could imagine this possible is if I could somehow find the connection between the reduction level number that is reported and the actual size of the video produced. Any thoughts appreciated, I know it's kinda weird.

Uhhhh....

Are you serious?

Find actual size, fine percentage reduction used (is it in the log? have a look!!!!!!!)...

With those 2 bits of info you can work it out yourself.

SOURCE_VIDEO_SIZE=

Yep.

If you're trying to tell me I can use the reported percentage and the size of the output to find the original size... then you would be incorrect. It never works out.

If you have the INF file, it is listed:

SOURCE_VIDEO_SIZE=

I have a 'rebuilder.inf' in the working path, however there is no mention of the string above. I do have an 'Original_Size', although it probably doesn't matter since I have done other jobs already.

It would have been named after the job and would have been in the directory selected as "Working Path" in BD-RB. Something like "APOCALYPSE_NOW.INF"

I'm actually using DVD-RB, not the blue-ray version. Hope I'm in the correct forum. What exactly does the reduction level refer to? The video only(w/o audio)? Video w/ audio? The entire file structure? A perceived level of quality?

The entire file structure? A perceived level of quality? Video reduction required. The audio/subs in DVD-RB is always kept intact.
