Step 3. Click video setting and adjust the video parameter including bitrate, frame rate, resolution or more to reduce its size. If you find the size is still not satisfying, cutting the extra parts of the movie or cropping the image are also accessible.

Bonus Tip

Can I change the parameters as I want causally?

No. Some people try to reduce the bitrate to shrink the movie file. However, in common situations, you just don’t allowed to change the bit rate directly. When you understand that the bit rate is decided by frame size (resolution) and frame rate (fps), you will know why. So you can customize the resolution and frame rate to reduce movie size. Here it has to be noted that the resolution is better not to be lowered by a large scale, because it will make the movie unwatchable after compression. In addition, for adjustment made on frame rate may harm the smoothness of the movie playback, we recommend you not to change it a lot.
