Here is one free video editor that practitioners should check out; not just for themselves but for their learners to use before submitting evidence for portfolios.

vReveal is software that offers basic one-click editing for videos allowing users to...

• stabilize,
  
• sharpen and
• clear up blurry videos easily (I know because I've tried it out with a video clip taken by Colin)

Once vReveal has been installed, start by...

• importing videos into the gallery;
• select the video to edit and preview...
