What Is MPG
MPG is a video format that uses MPEG-1 or MPEG-2 compression. Therefore, it can reduce the video file size while maintaining a suitable viewing quality. MPG is supported on a wide range of software and hardware on Mac and Windows systems.
Now, the MPG format is still in use. Although the MPEG-1 compression used by MPG is not as efficient as some modern formats, it can still be used in some older systems, such as DVD players.
Why Compress MPG Files
Nowadays, many online platforms have video size limits, which can be a problem for users. Don’t worry, you can compress your MPG file to meet their restrictions. In addition, compressed MPG files upload to the platform faster than the original.
If you want to share a large MPG file via email, you can also compress it first. Compressed MPG videos send faster. What’s more, compressing your MPG video file can also help you save a lot of storage space.
How to Compress MPG Video File
There are several methods for compressing the MPG video. For example, you can reduce the bitrate, resolution, or frame rate of it. You can also trim the MPG video to reduce the file size.
