C# screen recorder reduce AVI video file size

I'm currently trying to make a screen recorder in C#, and so far it works but the problem is that something as simple as a 20second video will take about 1GB of space. I have it setup so a timer continuously takes screenshots with this method:



void takeScreenshot()
{
Rectangle bounds = Screen.FromControl(this).Bounds;
using (Bitmap bitmap = new Bitmap(bounds.Width, bounds.Height))
{
using (Graphics g = Graphics.FromImage(bitmap))
{
//Add screen to bitmap:
g.CopyFromScreen(new Point(bounds.Left, bounds.Top), Point.Empty, bounds.Size);
}
//Create and save screenshot:
string name = path + "//screenshot-" + fileCount + ".jpeg";
bitmap.Save(name, ImageFormat.Jpeg);
inputImageSequence.Add(name);
fileCount++;

//Dispose of bitmap:
bitmap.Dispose();
}
}


And then it stores those pictures in a temporary folder in the D:// drive, and then when it's done it takes all the pictures and creates an AVI video out of them like this:



//Set bounds of video to screen size:
Rectangle bounds = Screen.FromControl(this).Bounds;
int width = bounds.Width;
int height = bounds.Height;

var framRate = 5;

using (var vFWriter = new VideoFileWriter())
{
//Create new video file:
vFWriter.Open(outputPath+"//video.avi", width, height, framRate, VideoCodec.Raw);

//Make each screenshot into a video frame:
foreach (var imageLocation in inputImageSequence)
{
Bitmap imageFrame = System.Drawing.Image.FromFile(imageLocation) as Bitmap;
vFWriter.WriteVideoFrame(imageFrame);
imageFrame.Dispose();
}
vFWriter.Close();
}
//Delete the screenshots and temporary folder:
DeletePath(path);


Any help on reducing the inefficiency of this is appreciated, I'm fairly new to this kind of programming.
