  • Double subtitles when hardcoding from .mkv container

    4 novembre 2022, par Goran Hinic

    I'm trying to hardcode subtitles into a file that's in .mkv container, using one of the subtitle strams from the container. I want subtitles to have a black background on them. I'm also trying to keep 10bit encoding and preserve high quiality. Result is ok, except that all subtitles are doubled. So there is a layer of good subtitles in white on black background, and also, half of the font size down, same subtitles in black. Can someone point out the issue with my command ?
Thank you.

    


    Ran this command :

    


    


    ffmpeg -i movie.mkv -vf "subtitles=movie.mkv:si=0:force_style='OutlineColour=&000000000,BorderStyle=3,Outline=3,Shadow=0,MarginV=20'" -c:v libx265 -crf 23 -preset slow -x265-params profile=main10 -c:a copy movie_subs.mkv

    


    


    Expected : White subtitles on black background
Actual : White subtitles on black background with black subtitles half font size down

    


  • FFMPEG, how to create custom waveform

    9 juin 2017, par Bodie Leonard

    I have done research trying to create a waveform with FFMPEG and am currently able to create a white png with the wave being transparent. The goal is to generate the wave like the smooth wave below and have the grey be transparent.
    ffmpeg wavform

    Here is my current FFMPEG waveform generator and output.

    ffmpeg -i ./_test.mp3 -filter_complex \
    
"[0:a]aformat=channel_layouts=mono,compand=gain=-6, \
    
showwavespic=s=450x46:colors=white,negate[a]; \
    
color=white:450x46[c]; \
    
[c][a]alphamerge"  -vframes 1 _test.png

    ffmpeg wavform
