  • Applying the same filter many times before output [duplicate]

    19 août 2019, par Fabián

    This question already has an answer here :

    In my video there’s an object that has shades of yellow (more orange-like) and has a solid yellow as background.
    I need to output all frames into a png sequence, using a color key filter to replace the yellow from the background :

    ffmpeg -ss 4 -i original.mp4 -t 2 -filter_complex "[0:v]colorkey=0xfff31b:0.125:0[ckout]" -map "[ckout]" colorkey-%d.png

    This removes all the yellow background. However, it leaves some pints of yellow behind, and some items are yellow-themed, so blending isn’t an option for this scenario.

    In the end I need to get rid of 4 specific yellow-colors from the frames : 0xfff31b, 0xfae56b, 0xfaec46 and 0xeee2a0. My idea is to run the same filter for every color.

    So first I tried this :

    ffmpeg -ss 4 -i original.mp4 -t 2 -filter_complex "[0:v]colorkey=0xfff31b:0.4:0[ckout1];[0:v]colorkey=0xfae56b:0.4:0[ckout2];[0:v]colorkey=0xfaec46:0.4:0[ckout3];[0:v]colorkey=0xeee2a0:0.4:0[ckout4]" -map "[ckout4]" colorkeyrefined-%d.png

    Then this :

    ffmpeg -ss 4 -i original.mp4 -t 2 -filter_complex "[0:v]colorkey=0xfff31b:0.4:0[ckout]" -filter_complex "[0:v]colorkey=0xfae56b:0.4:0[ckout]" -filter_complex "[0:v]colorkey=0xfaec46:0.4:0[ckout]" -filter_complex "[0:v]colorkey=0xeee2a0:0.4:0[ckout]" -map "[ckout]" colorkeyrefined-%d.png

    But both display the same error :

    Filter colorkey has an unconnected output.

    Is there a way to apply the colorkey 4 times (with the mentioned values) in one go ?

  • Fuse video with various audios ; adjust speed and offset [closed]

    16 octobre 2023, par 李志博

    I have a muted video and multiple audio files that need to be merged. Each audio file represents a different time segment of the video. While merging, I need to specify the position of each audio file in the video, as well as their playback speed and corresponding time segment in the video. The final output should be a complete video with merged audio. How can I achieve this ?
