  • FFMPEG : burn SRT files to a transparent video file ?

    19 septembre 2017, par Taapo

    I need to create several versions of srt/ssa subtitles for another editor. To minimize the problems that can rise (encoding, etc) I want to provide a separate AVI file that can be overlayed onto another file.

    So I would like to use FFMPEG to burn an "empty" (transparent) video file which has the length of the subtitle file, and with the subtitles burnt in. How would this be done in FFMPEG ?

    Before someone says this is a bad idea (which someone already did), there are use cases where this technique would be helpful. I’m fully aware that this would create big files, but most real-life editors don’t care about size - but about solutions. Judging from other posts (on other forums) there seem to be a need for others as well. And since a professional subtitler like Lemony Subtitler is offering the option, I suppose this is not really a bad idea.

  • FFMPEG copying Windows Media Audio 9.2

    19 avril 2016, par David GC

    I want to top and tail a wma file with a codec Windows Media Audio 9.2. I know Windows Media Audio 9 Professional encoding is not supported. But I just need to top and tail this audio file.

    I only get an audio file output with codec Windows Media Audio 8.

    ffmpeg -i .\1_encoding.wmv -acodec copy -preset ultrafast .\prueba1.wma

    Is it possible to get an output with Windows Media Audio 9.2 ?

  • command line settings for audio equalizer ffmpeg sox

    9 novembre 2016, par user1320370

    I need to add an equalizer effect on some flac files :

    f=4043, 1.65q, g=9.5; f=7024, 1.09q, g=3.7; f=9254, 0.94q, g=-2.5

    I have tried ffmpeg :

    ffmpeg -i solovoce_compress.flac -af equalizer=f=4043:width_type=q:w=1.65:g=9.5, equalizer=f=7024:width_type=q:w=1.09:g=3.7,equalizer=f=9254:width_type=q:w=0.94:g=-2.5 solovoce_equalizzato.flac

    but the result different to what I expect. These values were calculated by izotope ozone (professional audio editor software) and tested.

    I used the equivalent with sox and the result is the same.

    At this point I would like to try ffmpeg ’anequalizer’ filter that shows the graph so I can ’see’ the difference, but the documentation to show the graph is not clear and I have not found anything about it on the web.

    Can someone can please give me an example of how to use ’anequalizer’ with the plot enabled ?
