Though the video format MP4 is well known all around, still there are some unfamiliar infomations we know less. Like MP4 can do what kind of things? How common is it used? And what it is the relationship between mp4 and other video files? With these questions, I will introduce this useful video file format deeper.
Okay, what can mp4 do? Into another speaking, where we always use mp4? So far, the most portable devices I known all use this video format as iPod, PSP, Wii, Zune and so on. MP4 is developed to use for these. MP4 is not exact MPEG-4, mp4 is a part of MPEG-4. In our daily life, almost use mp4 everywhere, example your iPod touch videos, your PSP videos, you convert DVD to mp4 or convert DVD to m4v which is alike mp4, to put them into your devices than take them everywhere. So this is very common used file? Yes. I talked about M4V just now, and what’s the relationship between them? MP4 is one part of MPEG-4 and M4V is another part of MPEG-2. There are brothers! And M4V is common used for videos for iPods and PSP more than mp4. And audio file of m4v is m4a, just like the relationship between mp3 and mp4!
Of course you can choose other video file to enjoy DVDs, like convert DVD to mkv, or convert DVD to rmvb, they all very high-distinct and run fast.
