I'm not a translator (yet, so I don't know if it's a new idea), but I had an idea to make the video's easier for people who don't understand english.
If you don't understand english, the video's are hard to follow, even with the translations, because you don't know at what time the right things are said. And the video's are quite long. So my idea is to refer in the translation to the time when it is said (like on youtube).
3.36 - (closeup to the hands) "And now let's have a look at..." (only it's translated of course =) )
Hope you like/understand the idea (or even read it XD...)
