Here is my edited script I changed it so the audio and video use fifo's to get rid of
tmp files. I also changed
-V to 230
-b to 2430 found a bit calc and chose a higher bitrate for the size I use
added -B 122 which is my audio bitrate *96 + 1% of a+v
-I to 0 since I added deinterlacing since I set that
-q to 10 man says it is a good one for svcd even I still don't understand what it does
I was checking the man page and came across this and would like a bit of info and
suggestions on use
"-Q|--quantisation-reduction 0.0..4.0
This flag sets the amount quantisation is reduced for blocks containing
unusually large amounts of sharp image detail. Setting this value 0.0 produces the
most efficient use of bits but may cause visible/artefacting around detailed
sections. A larger value may help suppress artefacts, however, on noisy source
material this may cause a "swimming" effect on textured backgrounds as the noise cause
blocks to be boosted at random. The default is 0.0 (off)."
My source material has a little noise but I also hate artifacts/blocks so is there a
good setting
