The AVI format movie is not HD's

Problem Description: I am a film lover, usually always like to use the computer to see the movie, inadvertently found that there are many formats, I now want to know AVI format movies belong to high-definition movies?

Answer: The resolution to determine whether the film HD, there are two kinds: one is 1920*1080, the other is 1280*720. And now the mainstream DV machine (refers to the non-HD DV) to take the video for 720*576, the DV machine belongs to the SD pixel, DVD 640*480 and VCD used 320*240 these general signals.

Video in AVI format is a lossless encoding compared to other formats, and is relatively clear. But the video resolution of AVI format is different, we commonly used DV format for 720*576, but out of 640*480, 320*240, some camera video is also AVI format, only 177*144, you can say these are high-definition? These are not high-definition, not to the HD Rate resolution requirements!

So we say that distinguishing whether the HD movie is looking at the resolution of the movie. and file format, such as AVI, if the resolution to achieve high-definition standards, then the quality of the loss of other formats will be smaller and better!
