Hi hi hi ... I'm not too sure if I should be posting here or the newbie forum, but since I don't consider myself a "newbie" newbie, I'll post it here :)
OK, I've had lots of experience with Flask, and I must say GKnot/Nandub gives superior quality for the same filesize. I encode a lot of Japanimation episodes, which are normally circa-21 minutes long. Now, I want to have a consistent filesize for all episodes within a series, but I'm having problems using GKnot to achieve this. I have variations in filesize of up to 40% from the targeted filesize.
What I normally do (as in doom9's guide), is to run a compressibility check on the file, adjust the resolution accordingly so that the Load is about 80-90% of the Compressibility test's average bits/pixel/frame. I assume the variation in filesize is because of big differences in motion in the videos themselves.
A few questions:
(1) Does the % Load correspond the % of the total filesize specified in the "Bitrate" tab?
(2) Is it okay to have a % Load of > 100%, so that I don't have different episodes with different resolutions, etc?
(3) Why does the final filesize differ in size so much from projected filesize? With 2-pass DivX 3.11, shouldn't the info from first pass be automatically used to calculate actual encoding bitrate to achieve target filesize?
(4) What steps can I take/Where can I get information to ensure that I can get more consistent filesizes? Or would it be more logical to say "I want consistent quality, and to hell with the filesize?"
Thanks for the help, guys!
