How do you make a video file smaller size?

How do I convert a 1080p mkv video to a 720/480/360p video to a video with a smaller file size since..?

• Whenever I convert my 1080p videos into videos with smaller frames, the video size still gets larger, and I really need to get it down. How do I? All of the video converters I have used always make the file size larger even with smaller frames. Any idea on how to solve this?

• Answer:

  i know three exact ways for you to make videos smaller. 1. convert videos-- convert your video to lower quality video like from hd video to general video. or convert your video to Flv video. You can try this total video converter: http://goo.gl/xjJlb 2. set video biterates.-- video biterate has a lot to do with the video quality and video size. frankly speaking, you can make the video smaller by change the number of biterates smaller. 3. trim video---this way can help you change the video into several parts and evry parts seems smaller, but if you wanna save all, it is the same.
