ass2bdnxml v0.7a
Changes
- Detect false positive of "changed" ASS_Image by comparing the current blended RGBA composition to the last one. This fixes the excessive event generation whenever some ASSDraw were encountered.
- Optimise palette generation for the PGS format. 256 (255 with
--rleopt
) are now usable rather than 255 (254 resp.) - Always allocate the background transparent pixel to the last palette entry (0xFF typically).
- Adaptively reduce the usable number of colors by one when no transparency is found in a blended image.
Notes / Q&A
- "I get line width/encoding errors when I import the BDN in Scenarist." ➜ Use
--rleopt
flag. You could also reduce the max color count in--quantize
. - "I would like to reduce the total filesize." ➜ Use
--liq-quality N
, N below 100. E.g 90 is visually lossless and will significantly reduce the PNG files, and hence, the PGS bitrate. - "I want to generate the BDN for SUPer" ➜ Do NOT use
--quantize
or--split
. - "For SD-BD, the resulting PGS is stretched." ➜ You must set the
--par
or the--width-store
appropriately.
