    13 avril 2011, par

  • Chroma Key replace green color part with another image using FFMPEG

    15 septembre 2021, par Welborn Machado

    Chroma Key Image

    



    I want to replace green color of the above chromekey image with another image. The image should only replace with the green color not overlay entire image.

    



    I am using following sample command below but it overlay the entire image not only the green color.

    



    -y -i /storage/emulated/0/dummyResized.jpg -i /storage/emulated/0/circularImage.png -filter_complex [1:v]colorkey=green:0.3:0.2[ckout] ;[0:v][ckout]overlay[out] -map [out] /storage/emulated/0/outputBlackCircular.jpg

    


  • How to split one overlay script to multiple part scripts ?

    4 mai 2024, par mikezang

    I can slide 30 images from left to center and countdown 10 seconds, then keep slide to left..., but run this script more than hours...

    


    script.txt

    I think that I can split script to create 30 parts video then merge them to shorten time :

    v01.mp4 is no any problems.

    -filter_complex_script script-02.txt -t 10 -y v02.mp4


    


    but this v02.mp4 is the same as v01.mp4 without slide next image, I also tried -loop 1 "v01.mp4", that will be error, what can I do to create v02.mp4 as the same affect with full script ?

    


    ====================================================

    


    I got what I wonder, script-02 should be as below :

    


    script-02.txt
[0:v]scale=864:504:force_original_aspect_ratio=decrease,pad=864:504 :-1 :-1,setsar=1[s0] ;

    [s0][s1]overlay=x='if(between(t,0,10),max(W-w*t,0),max(0-w*(t-10),0-W))',
drawtext=fontfile='/WINDOWS/Fonts/Arial.ttf':text='%{eif\:10-t\:d}':
box=1:boxborderw=10|10:fontsize=24:x=w-tw-10:y=10:boxcolor=orange@0.4:fontcolor=red:enable='between(t,0,10)';

    I got error when trying to run a python script. Iam trying to make a project based on pyimagesearch tutorial.

    



    Code :
In first script :

    



    filename = tempVideo.path[tempVideo.path.rfind("/") + 1:]
    s3.upload_file(tempVideo.path, self.conf["s3_bucket"],
        filename, ExtraArgs={"ACL": "public-read",
        "ContentType": "video/mp4"})


    



    In main script :

    



    tempVideo = TempFile(ext=".mp4")
    writer = cv2.VideoWriter(tempVideo.path, 0x21, 30, (W, H),
        True)


    



    Error I recieved :
