  • FFMPEG Command to format videos to TikTok's specs ?

    8 juin 2021, par Christopher Sparks

    I'm trying upload a video exported by windows video editor to tiktok. It's a .mp4 file, and while it does upload, it isn't "TikTok'd", meaning, it only takes up the middle of screen. I was wondering what the ffmpeg command would be to output a video to TikToks specs.

    


    Here's how it currently looks.

    


    TikTok bad format

    


    And here's how I want it to look.

  • Use palette when using FFMpeg overlay

    16 avril 2017, par nbrogi

    I’m trying to add an overlay to an animated GIF with FFMpeg.

    It works, but the quality is pretty dismal. Basically, I’m unable to use the palette that I generate, and that leads to a lot of dither. The main GIF (meaning, not the overlay) is also very low resolution.

    I would also like to apply opacity to the watermark (and at one point that worked, too), but that’s a plus.

    This is what I have :

    ffmpeg -v error -i image.gif -vf 'palettegen' palette.png -y;
    
ffmpeg -v error -i image.gif -i watermark.gif -i palette.png -filter_complex '[1:v]scale=80:30, [0:v]overlay=(main_w-overlay_w) - main_h/30:(main_h-overlay_h) - main_h/30, paletteuse' -an image-watermark.gif -y

    At one point I was able to use the palette for the main GIF, so its quality improved. However, the watermark looked pretty bad. It’s pretty obvious that I have to do the overlay, and then the palette, so that the palette include the colors present in the watermark. However, I have no idea how to do that.

    Can someone point me in the right direction ?

  • Next drawtext clears the previous one ffmpeg

    27 août 2021, par Макс Шульдинер
    ffmpeg.exe -i ffmpeg_inputs/zheltiy_chelik.mp4  -vf "[in]drawtext=fonts/Temporarium.otf:text='r':fontcolor=orange:fontsize=100:x=(w-text_w)/2+0:y=0:enable='between(t,0, 11)', drawtext =fonts/Temporarium.otf:text = 'r':fontcolor=orange:fontsize=100:x=(w-text_w)/2+20:y=0:enable='between(t,11, 22)', drawtext =fonts/Temporarium.otf:text = 'r':fontcolor=orange:fontsize=100:x=(w-text_w)/2+40:y=0:enable='between(t,22, 33)'[out]" ffmpeg_outputs/test2.mp4 -y 


    


    There is such a ffmpeg line. Its meaning is to draw a letter 20 pixels to the right of the current position of the word every 11 seconds, and in this way "write the word". But here's the problem - when the second letter starts to render, it overwrites the first, and the third, respectively, overwrites the second. The string seems to have prescribed [in] and [out] but does not help, maybe someone has ideas
