Troubleshooting HEIFS to AVIFS Conversion

!Converting HEIFS to AVIFS gives blurry output → increase the quality setting before conversion
!Colors look different in AVIFS than HEIFS → check color profile mismatch (sRGB vs Adobe RGB)
!File size changed more than expected → AVIFS uses different compression, file size differences of 2-5x are normal
!Transparent areas in HEIFS turned white in AVIFS → AVIFS may not support transparency
