Movies in avi format are not HD
Description: I am a movie lover. I always like to watch movies with my computer. I casually found that there are many formats in movies. I want to know AVI format now. Is the movie a high-definition movie?
Question Answer: Judging whether the movie is HD by resolution, there are currently two types: one is 1920*1080, and the other is 1280*720. Now the video of the mainstream DV machine (referred to as non-HD DV) is 720*576. This DV machine belongs to standard definition pixels, 640*480 for DVD and 320*240 for VCD.
Video in AVI format is a lossless encoding method compared to video in other formats, which is relatively clear. But the video resolution of AVI format is different. Our commonly used DV format is 720*576, but there are 640*480, 320*240, and some cameras take video in AVI format, only 177*144, you can Said these are high-definition? These are not high-definition, can not meet the requirements of high-definition resolution!
So we say, distinguish whether high-definition movies, see the resolution of the film. The format of the file, such as AVI, if the resolution reaches the HD standard, the image quality loss will be smaller and better than other formats!
