Hi Kwag!

I noticed that your KDVD Half 1 Template uses B-Spoilage 20.

What actually IS B-Spoilage and P-Spoilage, and will higher numbers increase file-size and quality?

I just did some test encodes of frame 800 to 2300(1 minute) of my DVD Starship Troopers and the KVCD 352x576 PAL template with different B and P Spoilage settings. Encoding was directly from the .d2v

Kbytes P B

11408 0 0 (default)
10632 0 40
10568 40 0
9888 40 40
12432 -40 0
11572 0 -40
12756 -40 -40
10624 40 -40
11732 -40 40


Apart from the obvious conclusion that positive values reduces the filesize Im not quite sure what to make out of this. I dont have time right now to measure the visual quality of the clips. It might be an method to alternate the allocation of bitrate between B and P frames.

Thanks Rookie...

I'll run some test with B and P Spoilage 40 / 40 ... I don't think it influences the quality that much, compared to the decrease in filesize...

Thanks Rookie !!
