    contact the manufacturer of your camera for instructions on how to finalize an unfinalized clip
    maybe the user manual has instructions?

    BE SURE NOT TO FORMAT THE CARD until you finalized the clip in the camera

      Hey Anton, no Canon have NO information on this. appaerntly a lot of Canon users have had this issue and not had a resolution.
      There's a program you can buy for $130 that will repair broken DAT files, but I found a guy named Richard online who repairs them for $20 USD so I just paid him to fix it

          GH5's have the problem when using the battery grip and changing the grip battery without stopping and powering off the camera. If one waits for the camera to switch to the internal battery for a while it is fine. So it is possible to power and record for ever swapping batteries and cards but one has to follow the process. Wait for the battery to switch itself and card to switch. User error can mess the whole process up !! Having done this once I now switch off camera , take out card before changing battery. In most instances I do not need to do this for over 1 1/2 hours so usually get to do this in a break. So it is not just Canon.

              I have seen that many have had this happening but it seams to be easily recovered data that can be repaired by using recovery software, it sees in the data that this file is a video file it builds the video file from it.
