In the version 22.08.0 (linux appimage)
"Alpha MOV" works properly
"Alpha VP8" crashes as before ("[libvpx @ 0x7fe824002180] Transparency encoding
with auto_alt_ref does not work")
adding auto-alt-ref=0 in the options -> works fine.
"Alpha VP9" works properly
"Ut Video" works properly
my formerly working custom settings "prores/alpha" (f=mov acodec=pcm_s16le
vcodec=prores_ks vprofile=4444 vendor=ap10 pix_fmt=yuva444p10le
mlt_image_format=rgb24a qscale=%quality) does NOT (black pixels instead of
transparent), even not by changing pix_fmt to yuva420p and mlt_image_format to
rgba.
The last nightly build "kdenlive-master-325-linux-64-gcc" /
Kdenlive_Nightly_appimage-centos7 #325 (Version 22.11.70 (rev. 5cbc6403d))
behaves identically.
So maybe it's only the preset for "Alpha V8" that had to be changed. (If the
issue is reproducible in other systems).
I would be thankful to any hint that could explain why my custom preset still
not works.
