"I am trying to convert several MPG videos into MP4 format so as to edit them on my Windows computer and make a DVD copy of them. After trying many video programs, I was really disappointed as most programs reduce video quality after conversion. How can I convert MPG to MP4 without quality loss? Can anyone recommend an efficient converter program?"

Part 1. Comparison Between MP4 and MPG

MPG, also called MPEG, stands for the moving picture experts group. It uses MPEG-1 or MPEG-2 compression. It is a format specializing in standardizing motion diagram (MPEG video) and its audio codec (MPEG audio). This format stores video, audio, and metadata interleaved together. MPG files are often used for creating movies that are distributed on the Internet. There are a large number of applications to store MPG files.


MP4, also known as MPEG-4, is a digital multimedia container format widely-used currently. Generally, this format is used to store video and audio. Furthermore, it can also be employed to hold other data such as subtitles and static images. MP4 supports streaming videos over the Internet like most container formats.


MPG, however, does not support lossless compression. That's to say if you expect MPG videos of very high quality, a low compression ratio, and a larger file size will be required. So, to save more storage space and to improve video file reading speed, MP4 format is the better choice. Plus, MPEG videos aren't as flexible as videos in other formats, making it a poor format for editing video.
