I am trying to make xfade transitions for a list of input videos.
All transition types are working fine except these five:
- hblur
- wipetl
- wipebl
- wipetr
- wipebr
I'm on:
- ffmpeg version: 4.3.1
- OS: OSX 10.15.6
It looks like the same is happening on Alpine Linux 3.12
Here is the command:
{{{
ffmpeg -y \
-i 1.mp4 \
-i 2.mp4 \
-i 3.mp4 \
-filter_complex
"[0][1]xfade=transition=hblur:duration=0.5:offset=4.066[V1];\
[V1][2]xfade=transition=hblur:duration=0.5:offset=12.142,format=yuv420p[video];\
[0:a][1:a]acrossfade=d=0.5:c1=tri:c2=tri[A1];\
[A1][2:a]acrossfade=d=0.5:c1=tri:c2=tri[audio]" \
-map "[video]" -map "[audio]" video.mp4
}}}
Here is the output:
