2. Resizing video by changing video resolution or format

The most effective and easy way to resize a video is to change the video resolution. This can easily be achieved by Video Editor. After importing your files to the program, directly hit the "Export" button on the right side of the toolbar and go to the "Format" tab. You can click the Format list and choose a suitable format. Or change the settings of resolution, frame rate, bit rate, encoder, sample rate, etc. For example, by changing the resolution to 320x240 resolution, and reduce the video frame rate 15 fps, a FLV video of about 3 minutes will be exported to an 18MB FLV file. Not enough? Lower the bit rate and/or frame rate to get a smaller output file if your source video is long.
