Your file is downloaded as mp4 and is truncated.
Here is nothing to convert.

The atom that describes all the properties of the video is usually at the end of an MP4 file. Without that the video cannot be accessed. If the file you uploaded is all you have you are probably SOL. If you have the entire file you can try using ffmpeg to remux or convert. ProWo's GUI front end for ffmpeg may help you.

There are lots of other GUIs too.

Are these files from a LucasArts game? It's quite common for game companies to use standard containers but with a slight modification so only their software will know how to play it. So it's possible the files aren't corrupt or truncated, just non-standard. So you might be able to find a program that converts or remuxes them. The files definitely start out with an MP4 header (you can see it in any hex editor). You can also see an x264 metadata field.

By changing one byte in the mp4 header I was able to make the file readable by MediaInfo:

Are those the properties you expected to see? The file still isn't playable. I suspect the video and audio data are encrypted. 27 MB is rather small for a video of those dimensions and length.
