Intel Quick Sync QSV- Hardware accelerate h.264 encoding

The price of Camtasia seems a bit high I was tired to searching for a screen cap and editing software and I know this one worked because other admins in my office use it. I was kind of surprised to export my first video and see how long it took to encode and that it was using all of the CPU cores. 
I'm really surprised to find Camtasia does not support Intel Quick Sync. Why not? All of the libraries are free and it's not like you have to re-write your program to take advantage of this. The free and open source trans coder Handbreak has had support for QSV for quite sometime. They even support h.265 QSV.

Why can't you add Quick Sync?

Regarding the video you rendered in Camtasia: What kind of computer do you have? CPU?, RAM?, Drives?, Video Card? How long did it take to render? How long is the video?
One last step: Let's say its a 15 minute video "xxx.mp4" at 720p. How long does handbrake take to transcode it to an identically formatted mkv file?

That's not really the point. The question is why don't you support hardware encoding with Intel QuickSync. If you don't know what this is or why it would be beneficial look it up on Google. Google has all the answers and benchmarks you could ever need to know about it.

I find it hard to believe a maker of video software like this is unaware QVS or other hardware accelerated encoding options from AMD and Nvidia.

You keep saying the TechSmith is unaware. I doubt that.
In Camtasia 2018, TechSmith allows the video card to accelerate graphics and if nVidia uses the Intel APIs, and I assure they do, then Camtasia allows the nVidia engine to do that job.
The software engineers at nVidia may be better suited to answer your questions and I know first hand, they answer their emails. BTW, Intel & nVidia work very closely - each knows what the other is doing, while they're doing it.
You originally stated that Handbrake uses QVS - I verified it does via nVidia! If you visit handbrakes' open source community, you'll notice 7900+ problems handbrake users are having and attributing them to QVS.
Actually Camtasia 2018 users have reported many of the same "freezing" problems which are magically cured when the user turns on "software" vs "hardware" acceleration. 
BTW, looks like I dodged a bullet when I opted to not upgrade my GTX 970 to a 1070 on my 4790K system. And I had always thought it was dumb Irish luck that I never experienced the problems others have.

So.. you're still not answering the question of why Camtasia does not support Intel Quick sync.

I have no idea what you are rambling about Handbreak supporting QVS from nVidia.. err.. or how that relates to any of this.. but ok.. I'm talking about QSV Quick Sync Vidio, an Intel ONLY technology.

I'm talking about QSV.. QSSSSSSV god.. i love people like you.

Please know what you're talking about before you open your mouth.

Yea, my head/mouth said QSV, the hand typed QVS. It's called dislexia.

Your first Intel link listed a couple dozen programs that use QVS - oops QSV and now I ask,  why would Camtasia would want to cut off half  (or more) of their customer base? (see Big Red arrow).
Also note, Nimble software DOES NOT USE QSV in software.  god . . I just love people . .

Where did Nimble Streamer come from in this conversion.

Anyway.. Anyone from Techsmith care to comment? Hardware encoding?
