Can't open Elements Video in video soft (Vegas, Adobe Media Encoder, Premiere CS6 or After Effect CS6)

Can anyone help how to import files like this: to Premiere CS6, Media Encoder CS6 or Vegas 15?

Why many video files on envato elements are saved in unsupported format for popular software? Why it’s not just MP4 or AVI, or simple MOV which can be open with Adobe Premiere CS6? I have the same problem with many video files :frowning:
