Well, Video Guest, you make a good point here. MKV is a more efficient format that compress your video to a smaller file size based on the same bit rate, frame rate, resolution, etc. The video converter mentioned in this article can also help you further compress your video file by letting you manually adjust the bit rate, frame rate, and resolution parameters in the settings window.
Video Guest
converting an AVI to MKV does not automatically make a smaller file. MKV is a container, like AVI. The codec, such as MPEG, divX, MP4, determines how effeciently the video is compressed.
