Easy to use

FFmpegArg ffmpegArg = new FFmpegArg().OverWriteOutput();

var green_video = ffmpegArg.AddVideoInput(new VideoFileInput(@"chromakey.mp4")
    .SsPosition(TimeSpan.FromSeconds(0.5)));
var background_video = ffmpegArg.AddVideoInput(new VideoFileInput(@"background.mp4")
    .SsPosition(TimeSpan.FromSeconds(1))
    .ToPosition(TimeSpan.FromSeconds(10)));

var color_keys = green_video.ImageMaps.First()
    .ColorKeyFilter().Color(Color.FromArgb(101, 220, 8)).Similarity(0.25f)//ColorKey
        .Enable("between(t,0,10)").MapOut//ITimelineSupport
    .ScaleFilter().W("iw/3").H("ih/3").MapOut
    .SplitFilter(2).MapsOut;//Scale

var overlay = color_keys.First()
    //overlay color_key on-center background_video
    .OverlayFilterOn(background_video.ImageMaps.First()).X("(W-w)/2").Y("(H-h)/2").MapOut;

ffmpegArg.AddOutput(new VideoFileOutput(@"out.mp4", overlay, background_video.AudioMaps.First()).Fps(24));
ffmpegArg.AddOutput(new VideoFileOutput(@"out2.mp4", color_keys.Last(), background_video.AudioMaps.First()).Fps(30));

var renderResult = ffmpegArg
    .Render(c => c
        .WithFFmpegBinaryPath("path to ffmpeg.exe")
        .WithWorkingDirectory(Directory.GetCurrentDirectory()))
    .Execute();
