All in all, the fix was easy and took me about 15 minutes. I might have been able to do it a bit faster if the camera has not been in way at a time. So far the problem has not repeated itself. I didn't mention it on the video, but I also added a dash of glue to the belt end. I do hope it'll help it to keep well put.
I have also renamed posts which have video files embedded. I hope it'll make finding the clips easier.
