How to reduce the file size of video without losing quality? A widespread asked question. This remind me a question: Is it possible to convert video without losing quality?(Search on youtube: video room 1000 complete mix.) Don't get me wrong: it's "Keep the quality" not "Without losing quality".

Some common problems: The Video Pixel is too large that it can’t be full-screen played on your Player. The video file takes up too much space. The video file size is too large that you can’t watch it on your Mobile/Digital Device, or it can’t be uploaded onto video sharing web sites…some more. To deal with those problems, i think the easiest way is to reduce the video file size. Here we mainly talk about several simple ways to reduce the file size of video: Edit video, Convert the video, Set the video parameters. They are very easy to operate.

Just need a 3rd party software that has some simple functions: Crop video black edges, Convert video, Adjust video parameters. Here we use Video Audio Converter – Video Sharer – an all in one video downloader editor, video/audio converter player. How to reduce the video file size and keep the quality? Let’s take a look:

Crop video black edges – edit video
No matter the video from streaming video sharing web sites, or from DVD ripped. Almost all the source video has the black edges. Whatever, your tiny screen player won’t like that, not to mention it takes up the file space. So just cut it off.

Convert video to video formats
I think this is the most direct and the easiest way to decrease video file size. Some asked, "What is the best format for video files with high quality and low file size?" This is also the keypoint. Make an example: Similar to select a best audio format for music player(case wma&mp3), the HD video with general video, H.264 and WMV, Flash, SWF. We just need to convert the HD format to general formats reduce the video size.
Then to Adjust some video parameters, we can realized: lower the video file size and keep the quality. Select the Video Size: 220×176, 640×480, 1280×1024…etc(Screenshot). Video Quality: highest to higher to high…, these are use to adjust the screen size, keep the video quality. Also Audio Quality can affects the file size, adjust it if needed.

Besides, you can also convert the video to the same format. E.g. convert HD AVI to General AVI format. I used the "Auto" setting to convert a 2G HD AVI format video tutorial to General AVI format, then upload to YouTube, the file size is less than 20M, and the video is also very clearly. You can have a try!

Above tips will help you lower the video file size. You can upload lower size video to YouTube, put full-screen video to your Mobile Phone, iPod, iPhone, LG, Nokia etc. or some other uses. Just some more clicks, they are easy for anyone of you.
