Opening an IMG_2712 Mov. file on Macbook Air?

Question

I was sent a few Quicktime videos with the tag IMG_2712 Mov. and then couldn't open them on a Macbook Air that has been updated so it has the quicktime software that comes with Maverick 10.9.5 Version (1.3 GH Intel Core 15). This tag is not listed in the Quicktime tags listed on the Apple site. Is there another application that will open them? I tried to put them in to iMovie without success.

The filename suggests the video was recorded on a digital camera or a device like an iPhone. For instance, an iPhone video would use the generic MOV file container to hold H.264 video with AAC audio which should normally be compatible with your QT X player. Unfortunately, depending on how the videos were handled, the data could be corrupted, the file containers could be corrupted, or the files may be being trapped by player for security reasons.
My recommendation would be to try playing the file in an app like VLC which might play files using codecs which are incompatible with or unconvertible by QT X. If the file plays in VLC, then you should be able to determine what codecs where used to create the file and whether or not the content should be QT X compatible. If file plays and is not QT X compatible, then the videos should be convertible to QT X formats. If the files play and are already in QT X compatible formats, then the files may a have a security problem which may be gotten around by simply copying the compressed data to a new file container. On the other hand, if the file will not open and play in an app like VLC, then it is most likely that the videos were corrupted before or during transmission to you and you would need to request the files be resent in a more diligent manner to avoid such problems.
