从屏幕捕获视频，文件很大吗？

Question

I'm using ScreenCaptureJob to try to capture video of my screen. While it works fine, the issue is that the files sizes are HUGE. A 2-3 minute recording will have a whopping 600 MB file size.

I've tried reducing the framerate but it doesn't do much, and even reducing the Quality to 10% only brought me down to 100 MB and it looks awful. That's about the filesize you'd expect for 3 minutes of a 1080p HD movie, not a terrible quality, 30 FPS screen recording.

Is there something here I am missing, or any way to fix this, or does ScreenCaptureJob just record massive file sizes? Perhaps there is a way to shrink these files, or a different method I should be using?

Thanks a ton for any help:

    private void CaptureMoni(string x)
    {

            try
            {

                Rectangle _screenRectangle = Screen.PrimaryScreen.Bounds;
                ScreenCaptureJob scJob = new ScreenCaptureJob();
                scJob.CaptureRectangle = _screenRectangle;
                scJob.ShowFlashingBoundary = true;
                scJob.ScreenCaptureVideoProfile.FrameRate = 30;
                scJob.ScreenCaptureVideoProfile.Quality = 10;
                scJob.CaptureMouseCursor = true;

                scJob.OutputScreenCaptureFileName = string.Format(@"C:\cSharp\10quality" + x +".wmv");
                if (File.Exists(scJob.OutputScreenCaptureFileName))
                {
                    File.Delete(scJob.OutputScreenCaptureFileName);
                }

scJob.Start();
[[ code to set recording time ]]
                scJob.Stop();
}
catch (Exception e) { }
}

Use ffmpeg to compile your files. for that u need to create sequence of images

@" -r 5 -i " + RawFolderPath + "img_1%04d.png -pattern_type sequence -start_number 0001 -pix_fmt yuv420p " + path + filename
