Some time ago I exported these videos using adobe premier (sorry, but I'm not sure what version) and for some reason there is an unusual effect which results in footage sometimes being completely fine, but for the most part distorted and I'm not sure why.
Please take a look at following link for examples of the footage

If for whatever reason, you see the videos perfectly or know what could be the cause, please let me know. It would be greatly appriciated.
