On Youtube you can speed up video keeping the voice sounding 'nice'.
In Camtasia you allow merely increasing the clip speed:
you implement it so that you can speed up video without making audio sound weird by 1.25,1,5,1.75 or by set amount by us before rendering the video?
Now we need to export audio (by going to Share>export audio only) then
edit audio in a third party audio editing tool.
It takes time to do it by exporting audio. This feature would be great because most people who talk slowly sounds better with increased by 1.25 speed.
I'd be glad to pay for a feature like that.
