Your compliments really build me up! Actually, I've already thought about some things, the question is, however, if it works out the way I planned... I hope to have the second video finished by the end of the month (beware, I'm known for breaking deadlines...). I'll try my best...

That was quite easy, I just asked Rebecka to do a reshoot of that scene
... No, seriously, I used a software called "Adobe After Effects" (I love that program). It has a built-in tracking function, which helps you to track the movement of significant spots in a Video, like the four corners of the picture on the locker. The data of the tracked four corners can then be used to distort a new image, in order to match the new image's corners with the tracked corners. The result is a replacement of an object in the original video - in this case, the replacement of the locker picture with elin's picture. Unfortunately, automatic analysing of tracking data is never that clean, depending on the source material. That means you have to do a lot of manual tweaking to make the replacement look convincing. In fact, it took me a couple of hours to change these few seconds of footage. If you look close enough, you can still see some wobbling in the picture, which is due to messy tracking points. But this little error usually goes unnoticed, as you can only see it for a few moments. Here you can see a longer version of the replaced footage:

There is a part with extreme unnatural wobbling, which - of course - isn't included in the final video. I hope my explanation makes some sense...
