The High Efficiency Video Codec / HEVC / h.265 codec has the same quality as h.264 with only half the file size.  Why doesn't Camtasia use this codec?  Camtasia uses h.264   It would be a huge difference in screencasting  https://en.wikipedia.org/wiki/High_Efficiency_Video_Coding

Since nobody else seems inclined to reply, I will have to reply to my own message.  After quite a bit of testing, I have found that H.265 offers higher resolution than H.264, but it does not LOOK any better than H.264.  H.265 requires far more CPU resources to both encode and play (decode).  H.265 files are not smaller than H.264 files, in fact, Camtasia's results with H.264 at the same resolution of H.265 are actually considerably SMALLER than H.265 (I think the reason is that Camtasia uses a special proprietary version of h.264) 
Almost no software supports H.265 while almost ALL software supports H.264.
It takes 7 times longer to encode to H.265 as H.264.

So, use H.264, especially Camtasia's H.264  which produces much smaller files at the same quality of other H.264 encoders.

Hi, Kip
I came to pretty much the same conclusions as you.

I didn't want to post it because I'm not affiliated with TechSmith and in no position to explain their position on this.

Regards, Joe
