Hi pat-h and welcome to the community
Your post seems to indicate you are possibly recording full
screen. Typically, this is not recommended. Is there any way to
reduce the size of your application window prior to recording? If
not, you are pretty well stuck with the option of resizing later.
As you have seen, resizing can make your movie lose clarity and
look blurry.
You can also try choosing a different position for the
playback controls. Either that, or remove them entirely and use
buttons or images of your own to control playback.
Hopefully this helps... Rick
