I have been using the MA script , gonna be encoding a black & white film , do i need to make any changes to the script?

Thanks in Advance.

You may want to place GreyScale() after your MPEG2Source/AVISource line to make sure that there is no chroma information.

You can also drop MergeChroma(Blur(1.5)) as it's of no use with B/W films.

Xvid codec has a black and white encoding mode which disregards color.
but i never used, don't know about the results.

tweak filter have the saturation adjust..turn to zero!
that i tested and works!

Steady filter :

maybe one of them can help too!

Using GreyScale() does the same trick, but it's an internal filter so no need to download anything

great Boulder!
i don't knew that.

guess I should've read this thread before I managed to squeeze a 3hr 24min B&W movie onto one KSVCD (352x28. It has an audio lag of about half a second, but since it's Japanese (with subs) then that really doesn't matter all that much.

So, my question - would the Greyscale() filter make much difference? To what? Filesize? CQ? both?

I became curious cos I felt really amazed to squeeze this full movie onto one 80min CDR and thought it maybe had something to do with it being old and B&W. I mean, because there are less colours to encode with each frame, shouldn't it logically follow that it will take less time AND/OR effort to encode compared to a full colour movie of the same length?

As usual, I'm only just thinking as I type....

maybe everything change and not only one parameter my friend.
nothing is bettert than tests (i think)

use trim (xxxx,xxxx) round 3000 frames in each script and encode....
will be faster and you remove all doubts about quality, size...etc!
