I took videos of the Swedish Glee Club Spring Concert. In total, I processed 14 videos of the singing.
It took 88 GB of data on our computer. I used iMovie to convert the data to m4v videos and then uploaded them to YouTube (actually at the moment I still need to upload the last 5 to UTube).
So if you are interested, all of the Swedish Glee Club videos are at (or will be at later today) SwedgleeClub channel.
In many respects, iy is easier to sing the songs, then process them & upload them!
