I did find all 50 but it was not easy! In each round, I paused the video until I had located all 5, taking well longer than the allotted time. I do enjoy the People magazine "Second Look", which is similar. In your puzzles, it is straightforward to determine whether to count something as one difference or two differences. In People, quite often an item is moved and that counts as one difference instead of two. If I count it as two, I stop looking before I have them all.
