I am having a recording error when recording to MP4

When I record to mp4 and then try to preview the file in quicktime, i can only make it about 6 minutes or so into the video before the video stops playing, almost as if the video is corrupt.

When I import the file to Final Cut Pro X to edit, the video acts the same way, it plays only about 6 minutes of the 50 minute or so file. The file is only about 450mb so its not that large. However, when I import the file into Adobe Premiere, the video is able to be fully viewed. However, during playback of the raw video in Premiere, it does some messed up playback after about 1 second of the video playing. Once the video pauses, the correct frame is rendered but during playback something weird with keyframes or something happens. This has been consistent with files since recording for the last month or 2. We did have a brief period of time when we started recording MP4s in the beta version that this was not an issue. I am attaching a link to a video that has this problem.

This video stops at 6:00 of about 27:00

Another video for instance stops at 3:30 of 32:00

There does not seem to be a pattern. Please advise.

Interesting. I tried playing it on the computer it was recorded on and it played fine. It seems to be when I play it on my Mac Pro. Quicktime will not let it go past the 6 min mark and I can't edit it in Final Cut. I will try to play it back within VLC on my mac and see what happens.
