  • How do I use ffmpeg to bulk scale videos of different sizes to the same size (some potentially with black bar padding) ?

    9 décembre 2020, par Tumbleweed53

    I have a bunch of videos I want to stitch together. I want to scale them all to the same size, maintaining aspect ratio (thus adding black bar padding if necessary). Some videos will be downscaled, but most upscaled.

    


    Does anyone have a clever ffmpeg scale formula to accomplish this ? My alternative is to iterate through every video and calculate the scale formula based on its size, but I'd prefer not to do that if I don't have to.

    


  • ffmpeg scale 4k video and add subtitles

    29 novembre 2020, par goodkid38

    I am having trouble scaling video from 4k to 1080 while still retaining the video sub titles. These subtitles are PGS based and therefore need to be baked into the output video. In order to scale the video I am using ffmpeg with a filter_complex like so :

    


    '-filter_complex', `[0:v][0:s:randomSubtitleHere]scale=1920:1080[scaled];[scaled][0:s:0]overlay[v]`, 
'-map', '[v]', '-map', 
`0:a:${movieTitle['audioSelect']}`,


    


    This will give me the video at 1080, but it i still am not seeing the subtitles I have selected.

    


  • Where do I add the FPS filter and scale filter to an ffmpeg command ?

    20 octobre 2020, par javinladish

    I am using this command to convert a folder of mp4s to webp using ffmpeg :

    


    for i in *.mp4; do ffmpeg -i "$i" "${i%.*}.webp"; done


    


    I want to add in an FPS filter and scale filter.

    


    -filter:v fps=fps=15

-vf scale=450:-1


    


    When I add in these filters to the command, I get errors. What is the correct way to add the filters to the command above ?
