Video format explained and compared

This article explains main video formats and later compares with photos the quality. Audio Video Interleave (.avi) Developed by Microsoft and released with Windows 3.1 way back when false teeth were still made out of wood, AVI files have been a work horse of digital video. Although its popularity has been waning, lots of legacy video in AVI can be found all over the web. More recently, AVI has been abandoned for Microsoft's WMV (Windows Media Video). One of the most maddening things about AVI today is that the format doesn't allow for specifying an aspect ratio, so a 16:9 AVI video may start displaying at 4:3 - this is less of a problem if your player allows you to manually select aspect ratios.

MPEG 2 vs H264 vs H265

As time moves away, compression techniques are created. As a beginning we all have seen an AVI movie about 2 hours and equal to 30-40 GB. After that nee techniques were invented with a main reason : Same quality, less storage. MPEG group created some compression standarts like MPEG1,2 and 4 but MPEG 2 became really important and is being used in many devices. What about H264 and H265? Well, the quality is the same but they use less memory in your disk, H265 < H264 < MPEG 2. But, is H265 worth? Well the simpliest answer is you but rembere : the higher the compression the higher the export time is. So if you have a powerfull computer use it. But H265 is new and it is not tested in some devices. The good news is that google supports H265. This format is the greatest solution for youtube videos.
