Why and How to Compress MPEG Files?

Why compress MPEG files?

MPEG, a Windows Media file format, is a set of codecs (a set of instructions) used for encoding and compressing audio/visual files, like movies and music. Although the compression techniques used in making MPEG files make the MPEGs smaller than other types of audio/video formats. However, you still still find that it is very difficult and time consuming for you to attache the MPEG file to an email, fit on a DVD disc or portable devices. The most simple way to fix this file size issue is to compress the MPEG files. The following article will share you some simple ways to compress MPEG files with either minimum quality loss or no quality loss.

How to compress MPEG files?

1. Convert MPEG to other more compressed file format

Here, you can choose to convert MPEG to other more compressed video format such as MP4, WMV, FLV, which are all good delivery file format for used on the Internet.

2. Lower MPEG file size, bit rate and frame rate

If you do not care too much about video quality but are looking for an efficient way to downsize MPEG files, just have a reference at the following 3 solutions:

– Lower file resolution: For HD MPEG files with file resolution of 1920×1080, it would be much ideal for you to reduce the file size to 1280×720, 640×480, 640×360 or other smaller resolutions
– Lower video bitrate: Lowering the bit rate will bring about the decrease of the video file size. But please keep in mind the image quality will be bad in case you make the bit rate too low.
– Lower video frame rate: Encode your video in the same frame rate that you recorded it in. If you recorded above 30 frames per second, encode in half that (for example, a 60 FPS video would be encoded at 30 FPS)

Tips: For SD video, use a bit rate between 2,000-5,000 kbps. 720p video should have a bit rate between 5,000-10,000 kbps. 1080p video should have a bit rate of 10,000-20,000 kbps.
