  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

  • ffmpeg extract alpha channel from prores

    17 janvier 2019, par vptest

    ffmpeg -i in.mov -hide_banner -f mp4 -vcodec libx264 -vf alphaextract,format=yuv420p out.mp4

    What I get from ffmpeg

  • Rounded corners in subtitle (Advanced Substation Alpha [.ass])

    3 mars, par Leander Mihm

I only found out that the BorderStyle 4 exists, because I was looking at this stackoverflow. Is there any good and complete documentation of the Advanced Substation Alpha format ?

    


    I'm currently using the following configuration :

    


    BorderStyle=4
Outline=10
