video problem
Not really chemistry related but...
I got a request from somebody on youtube to post a video of a tour in my homelab. So I did:
http://www.youtube.com/watch?v=NM5CjTwyNRo
However the video is dark. When filming the cupboard on the right, the dessicator, glasware and acids can hardly be seen, while watching the file
saved on my computer, I do see all these things.
How come this happens?

This depends on the video decoder software, used during the playback. I also see differences in videos on my website. With the VLC media player (which
I have made the default player) some videos show excessive flickering and intense variations in brightness, while the video itself was made in
constant daylight (overcast day, constant fairly bright daylight). With the Microsoft media player, there is no such flicker. Apparently different
software versions use different codecs.
I'm not sure how Youtube works and whether you can select the codec for playback. But I have the strong impression that this is the direction in which
you have to search the solution for your problem.

I have nearly always found that downloading and installing the latest K-Lite mega-codec pack fixes any problem with playing video.

And Virtualdub is my software of choice for video editing.
