Here are the requirements when making videos:

  • Video resolution should be 720p (1280 x 720 pixels) or higher.
  • If using a camera, make sure that the camera is steady; the angle is good; and the lighting is good.
  • Any text should be legible especially hand-written.
  • You need to write out the complete question before recording (do not record writing out the question).
  • Use a good microphone.
  • For most mics:  point the mic upwards and speak across the mic instead of into the mic.  This reduces the "breathy" noise and plosives.
  • If you have a handheld mic, move the mic away from your mouth when you breathe.
  • If you have a stationary mic, you can try to turn your head away when breathing.  You can also add a "pop filter" to reduce plosives.
  • You can edit out the breathing if it seems annoying.
  • If you have a long stretch of writing without speaking, you can speed up that section of the video.
  • When you make a speaking or writing error, pause for a few seconds so it is easier to edit out.

Here is a video on how to edit using Camtasia on Windows.  Here is a PDF, but I recommend watching the video.

If you want to do a really good edit job, expect to spend about 4 to 8 times the length of the video.
