Description

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:

Only git ffmpeg version is supported here.
Also your ffmpeg version is too old.
