    Kevin, thanks for all this insight

    why is this in registry only, and not made available to the user?  can you document some of theother registry switches?

    Hi 4evermaat,

    In Camtasia 9, we expose some of the rendering settings in Edit->Preferences->Advanced->Hardware Acceleration. And for settings here and some more advanced and hidden ones we use some defaults which work for most of cases. Since not all our customers are comfortable making registry changes, we tend to expose them only when needed (eg: sometimes Tech Support will use some hidden ones when interacting with customer issues). 

    Thanks!

    I mean, why hide them in the registry instead of putting them in the advanced section or another tab that would allow the user to explore?   Doesn't seem to be that dangerous.

    Sorry 4evermaat, I just saw your message. Yeah, your suggestion makes sense to me. We also need to run all this by our UX folks, they usually have the final say about what we would expose from the UI.

    Thanks!

    HI Kevin I have limited Camtasia 9 Memory/CPU usage on one of my computers in the lsat year
    but it was WAY simplier than you explain above

    I thought I did it right in Task manager??

    Currently im crashing when editing and rendering my movies

    This is a new computer HP Q119; with 12 gigs of ram, Core i5-6400t
    CPU speed: 2.2 GHz (2.8 GHz max turbo boost) CPU Cache: 6 MB TDP: 35 W
    Integrated graphics: Intel HD graphics (GT2)

    My much less powerful Sony Tap21 actually is more stable.. Takes longer but I managed to limit Camtasia CPU/memory usage to 80% and it works perfect.

    Now for the life of me I can not find how I controlled Camtasisa memory and cpu usage.

    Any ideas how to optimize windows 10 to prevent Camtasia from constantly crashing on dinky little 7 minute movies.

    Yes kevin I do see your other tips, THANKS but IM talking about just controlling the Camatasia memory / cpu usage as they max out and crash me.

    :) thanks Bill

    Hi Bill,

    Sorry Camtasia crashes on your computer. I too am curious why it'd crash, would you mind contacting our Tech Support and sharing your crash dump with us? The most recent crash dumps usually can be found in this folder: C:\Users\[your_name]\AppData\Local\TechSmith\Camtasia Studio\CrashDumps

    Thanks!

    Thanks Kevin Liu, this is very helpful information.

    Currently have two Core i7 6800k rigs solely built for Camtasia renderings. Right now both machines only see 75% CPU utilization evenly spread across all 12 threads. Changing the thread priority registry key mentioned above to '2' had no effect on CPU utilization for either machine - even after restarting and triple checking registry values. Is there anything else that may be holding us back???

    Hi Jeff,
    It could be something project-specific. During the production (encoding) process, it also relies on that decoding can give it fast enough frames for it to process. One caveat in decoding TREC streams (yes, TREC is Camtasia recording format), for example, is that it is basically single-threaded so that could be the bottleneck. There’s also a known bug that remix type of callouts are rendered every frame even when their content is unchanged. So if you have these on timeline, it may drag the encoding process down and not fully use the CPU power. If you have MP4 etc other content on timeline, you may see better/more CPU usage.  And 75% may not be that bad actually, compared to CS 8. Another factor could be that if you run production in hardware mode (default is software mode), it may use less CPU, but put some work on GPU.

    Thanks for the feedback!

    Thanks for your quick response. Yes, you're correct that v9 does utilize the processors a little better than 8. In our testing with 8.6, utilization was approx 65-70% as opposed to 75%. Enabling GPU render does reduce CPU usage, but always increases render time by 2-5%. 

    Specifically, we're working with .TREC files. Each file is approx 2 hours in length, recorded at standard XGA resolution. Each 2 hour file receives a fade transition at the beginning and end then is rendered into WMV format, retaining the native resolution - so there isn't much going on. 

    It's moreso a passing curiosity about why the machines seem to be limited to 75%. We've already met our goals for render speed - I'm just curious if we can get full utilization of our purpose-built PCs

    Have you guys been able to replicate the CPU cap issue on faster processors yet? I just updated both of our i7 6800k machines to Win 10 Build 1703 and the 70-75% CPU cap persists. Genuinely curious why we can't get the process to 100% utilization on either machine. 

    Let me know if someone from your team would like to look at our machines remotely and maybe play with registry settings, that is - if you havent been able to replicate the same issue.

    I use a program called ProcessLasso and you can either:
    1. Exempt Camtasia from ProBalance restraint
    2.  classify Camtasia as a 'High Performance Process'
    3. Set the Park Control (I think you can use Park Control as separate program without needing ProcessLasso)

    i need to discuss soe major things,
    i use camtasia for making youtube videos using images and voice over narration like The Richest Channel. But its a complex process which include multiple layers of images (background blurred images + normal images) , voice naration, music clip, animations on images and behaviours+transitions on all stuff. Problem is that , when i produce all this complex stuff to make video, it takes a loooooooot of time for small videos of 3 to 4 minutes. I am using camtasia 9.0.3 on hp core i7 with 6GB of Graphics (4GB Intel Shared + 2 GB Nvidia Geforce). I have set camtasia to use NVIDIA card but still it is very very low. When i render video, it produce it fast but i am using multiple images ( a lot of images) instead of videos, it should process it faster than videos but not. Please do something about it. I am using camtasia for 2 years and has always faced this issue. If your reporting agents are lazy then please hire me so that you make quick fixes as soon as possible.

    Hello anyway I could build a render farm with camtasia 9? do you provide render engine for the farm?

    I made this video with camtasia and I stopped rendering.

    I made all this videos but rendering project still cant use full graphics card it's hi end but camsation burns GPU i do all settings correct
