Oy. So I'm the one who has the KWTX video of Jarrell. It was acquired second hand from a chase DVD compiled by a small group of chasers in the early 2000s, and was supplied by Lon Curtis. He says the video is still under their copyright, hence why uploads are scarce. My guess is it's a combination of them knowing they have the best video of the tornado and wanting to milk it dry, and because of copyrights with Nat Geo and Discovery Channel as well. Obviously I can't upload the video, even though I want to (home videos and chase videos are one thing, pro video from a television station is another), but what I can do is supply an image sequence taken at that critical transition period (as far as I'm aware, those are the only few seconds of video not available online). It's only 56 images (the segment is 56 seconds), but maybe it could be of use.
