How to Compress MP4 Files effectively

Step 1. Add your MP4 files to the program

Step 2. Reduce the size of MP4 file

Next you need to drag the video from User's Album to the Timeline Panel and then click Create to activate the output interface. Now you are ready to slim down video size in the following two ways:

1) By changing output format

Formats like FLV, WMV, MOV have high compression rate. Video with these formats are relatively small in size. If you don't care to change the output format, then you can convert MP4 to any of those formats. To do this, you can hit the Format tab and select a new format from the drop-down list.

2) By adjusting the parameters of video

If you'd like to keep the original video format, you can adjust the related video parameters to get a smaller file. Click the arrow beside Advanced Settings to bring out the drop-down choices and put in your needed presets. Downgrade resolution and bit rate will make the video size smaller. But you'd better preview the clip to make sure the result is acceptable.

Note: Generally speaking, compressing a MP4 video will cause quality loss. But Video Editor won't let you see obvious reduction in picture quality.
