  • Fastest method to add .ass (ssa, aegisub) SubStationAlpha subs to mp4 ?

    23 mai 2015, par user3762355

    So i have video file mp4, and without changing its quality i want to add ass hardsubs.
    i am doin this with ffmpeg :
    on windows :

    ffmpeg -i input.mp4 -c:v libx264 -preset:v medium -profile:v baseline -level 3.0 -movflags +faststart -vf ass=insubs.ass -bufsize 4000k -qp 27 result.mp4

    But it takes long time, or quality is bad.
    It have to be most compatible, so baseline, and good for web.

    How to do it faster ?
    When i change preset to ultrafast quality is very very bad.

    I dont want to use mkvtoolnix and handbrake or avisynth.
    And it has to be on Windows.
    It has to be something, possible to do with one simple bat file, very fast, good quality,small size, just like original mp4 only with subs hardcoded.
    Thanks.

  • FFMpeg converts locally but not on Ubuntu production server

    1er janvier 2016, par LargeTuna

    I am using ffmpeg & this command to convert a .mov to .mp4. It works locally but it will not work on the production server.

     Command: /path/to/ffmpeg inputFile.MOV -vcodec libx264 -pix_fmt yuv420p -profile:v baseline -preset slow -crf 22 -movflags +faststart outputFile.mp4

    I have checked to see that ffmpeg is installed on the Ubuntu 14.04.x prod server...

     /usr/bin/ffmpeg

    I get this error each time :

    Thoughts ?
