    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • Word-by-word display of subtitles in FFMPEG ?

    10 mars 2020, par ThaDon

    I am trying to burn subtitles into a video such that they appear in a word-by-word fashion instead of all at once.

    What I mean by this is, a word will appear, then another word will appear next to it, and so on. Eventually the line will clear, then repeat.

    Example :

    enter image description here

    I thought I could create an Advanced Substation Alpha file where subtitles share the same end-time but differing start times, however FFMPEG doesn’t seem to cope very well when rendering the file :

Dialogue: 0,0:00:01.50,0:00:03.46,Default,,0,0,0,,subtitle

    The idea being that I'm would appear, then 1 second later a would show up next to it followed by subtitle a half second later

  • Why does ffmpeg output frames starting with 0001 instead of 0000 ? [closed]

    3 février 2020, par AMTQ

    I’m using ffmpeg to extract frames from a video. It all works well but something seems strange : The numbering of the output always starts with 0001 instead of 0000. Below a minimum working example, the output from the console and a picture of the generated frames. I’m using windows shell on Win10.

    ffmpeg -i P1390752.MP4 -vframes 4 frame%%04d.png

    Console output :

    C:\Users\xxxx>ffmpeg -i P1390752.MP4 -vframes 4 frame%04d.png

    What I tried so far :
    1) I restricted the output to 4 frames because otherwise it would take ages. But the problem remains the same when I remove the number of frames and extract the whole video. The problem persists when using a starting point with -ss and a duration.
    2) When I use jpg as output I get some warnings about depreceated pixel format, but the numbering issue remains.

    I can not get rid of the first two warnings concerning the keyframe, maybe this is related ?

  • ffmpeg - Replace one word audio in video at different specific timeline [duplicate]

    17 décembre 2019, par Siddharth

    This question is an exact duplicate of :

    How can i replace one word (newyork to be replaced by california) throughtout the video where speaker says "Newyork". I want that "Newyork" word to be removed from the audio (while keeping video intact) and insert "california" throughout the video at different places.

    I have an audio file where speaker says "California" which i want to replace with "newyork" word.

    How can i do that using FFMPEG ?
