3What Should You Know before Video Compression?

Before you start shrinking your videos, you'd better to know what are the key factors to affect your video size.

Video format

One video with different formats will have different sizes. Regularly, the smallest video file formsts are WMV, FLV, SWF, MPEG-4 and RealVideo, and MPEG-4 is the most popular as it still delivers good quality videos. MKV and AVI with high quality video always occupy large space. So if you want to keep the original resolution of the video, you can choose convert video between formats to downsize it.

Length of the video

The second factor is the length of the video. When anything changes on the video timeline you’re creating, the longer your file is, the larger your video size is. So you can trim the unwanted part of your video to change the video size.

Frame rate

Frame rate is how frequent are your key frames. Most of the videos are about 30 frames per second (fps). If you cut the number of frames in half, the video size will be cut in half either.

Bitrate

The size of the video file can be decreased by lowering its bitrate. Bitrate size is directly proportional to file size and thus reducing one will reduce the other as well. But here it needs to be understood that too much lowering of the bitrate will reduce the quality as well. Thus reducing bitrate by 20-30% of the original size is a good choice.

Resolution

The video resolution determines its size as well as quality. A high-resolution video will have good quality and a larger file size. Thus if you are aiming to reduce file size, reducing the resolution will do the trick. If you have HD videos with a high resolution of 1920 * 1080P, you can reduce it to 1280 X 720P, 640 X 480, 640 X 360 and other resolutions so as to decrease video size. The most commonly and recommended resolution is 640 X 480 as it is compatible with the majority of the mobile devices ( Android, iPhone, and iPad) and various popular sites including Facebook, Vimeo, and YouTube.
