  [![enter image description here](https://i.sstatic.net/g970l.jpg)](https://i.sstatic.net/g970l.jpg)I am using the command below to drawtext with rotation. This works but when set `fontcolor=black` It becomes transparent color.
  I am not understanding the reason.
  
  ```
  ffmpeg -i input.mp4 -filter_complex "color=black:100x100[c];[c][0]scale2ref[ct][mv];[ct]setsar=1,drawtext=fontfile='font.ttf':text='Test Text':fontsize=36:line_spacing=3:box=1:boxcolor=red@1:fontcolor=black,split[text][alpha];[text][alpha]alphamerge,rotate=45:ow=rotw(45):oh=roth(45):c=black@0[txta];[mv][txta]overlay=x='min(0,-H*sin(45))+100':y='min(0,W*sin(45))+50':shortest=1" output_video.mp4

  The method in my [old answer](https://stackoverflow.com/q/38306321/) was a workaround due to a limitation in drawtext filter at the time of writing. It's easier now.
  
  You're getting transparent text because the textcolor is used to set both the color as well as its opacity intensity, and since black represents 0, the text disappears.
  
  Anyway, it's simpler after ffmpeg 3.1
  
  `ffmpeg -i input.mp4 -filter_complex "color=black@0:100x100,format=yuva420p[c];[c][0]scale2ref[ct][mv];[ct]setsar=1,drawtext=fontfile='font.ttf':text='Test Text':fontsize=36:line_spacing=3:box=1:boxcolor=red@1:fontcolor=black,rotate=45:ow=rotw(45):oh=roth(45):c=black@0[txta];[mv][txta]overlay=x='min(0,-H*sin(45))+100':y='min(0,W*sin(45))+50':shortest=1" output_video.mp4`
