Firstly it depends on what program you are using to record the video screen capture for youtube. If you use the free camstudio one it comes out OK but not as good as camtasia of course. To see the writing clearly you need to make the space you are recording smaller. For example in camsudio I record my video at 320 by 240. This can be changed under the region menu. If you record in full screen and then it is shrunk to fit on youtube it becomes distorted. I am actually experimenting with camtasia but it has so many features that it becomes confusing. But you cannot beat the quality of camtasia...the writing turns out crystal clear if you zoom in correctly.
