Newer cameras may record as an MPEG transport stream with extensions such as .TS, .MTS, .M2T or .M2TS. Ultimately, all these videos are MPEG videos. If you change your file's extension to .MPEG or .MPG, you should be able to upload your recording successfully.

Windows sometimes conceals the extensions to your video files. In order to see all your file extensions, following these steps:
