When we get a nice video on the internet, we would be likely to download it to our computer or tablet for selection or sharing with others. But the most frustrating thing is to be told “Sorry, this video format is not supported.” or “Please download the special player to play this video”. And if the video is contained in MTS format, a new HD format with a 1440*1080 or 1920*1080 resolution, it would be harder for us to play it with the general player or devices that only support MP4 format. Because MTS video can be only played or processed with special devices and tools, and MP4 is supported by the most players and devices in the current market. For this reason, we have to convert MTS to MP4 online or to convert MTS to MP4 by some MTS to MP4 converters. Previously, we have talked about how to convert MTS to WMV.
