Thanks, it working now but for convertion from any format to avif nconvert still needs AVIFlib.dll, but since we have newer aom.dll can you plz make it work without AVIFlib.dll?
And I have now weird problem with converting files to jpeg-xl format on non unicode version (for unicode nconvert all fine) when it generating instead correct names something like "㼿㼿氿佄南卜卙䕔㍍尲䍖啒呎䵉ㅅ〴搮汬".

Code: Select all

nconvert.exe -32bits -out jpegxl -o rachel_.jxl -q 70 selfie5_4x.png

Thanks, now all works fine.
Btw why there are 2 versions maintained unicode and not? Since unicode should be better why keep updating ansi version and make it as main, does unicode have any flaws/cons comparing to non unicode one?

[xnview]

in the future there will be only unicode version

Code: Select all

nconvert.exe -v -32bits -out avif -o "rachel.avif" -avif_speed 8 -avif_quant_color 0 25 30 -avif_quant_alpha 0 25 30 "selfie5_4x.png"

Bad argument -'avif_quant_color'
New day, new problem so far. Is nconvert avif quality commands from

Code: Select all

nconvert -help

not actual anymore? So to set avif quality now I need to use something like "-q 60"?

yes, now nconvert uses libheif an no more aviflib

Problem with convertion to avif arise in latest version (probably due broken avif plugins integration), with older version (7.230) there are no such problems:

Code: Select all

G:\NConvert-win64>nconvert.exe -32bits -v -out avif -o output.avif -q 65 -avif_speed 7 input.webp

Good, thx. Also wanna mention (maybe already did it before) issue that doesn't exist with other formats except avif, other tools like IM, libvips can handle such files without problems. If I try to convert fake webp for example which in real is in avif format nconvert is not able to read such file. But at same time nconvert without problem handles renamed webp to .png and .jpg for example but with if input format = avif it fails to read such renamed (to .webp) files:

Code: Select all

nconvert.exe -32bits -v -out webp -o output.webp -q 80 input.webp
