Camtasia 2019 is slow and laggy

  • Updated 2 months ago
I just purchased version 2019 last week. It's been slow and laggy on 2 different computers. I first tried to run it using Parallels and Windows 10 on an iMac that is setup with quad-core i7s and 32gb of ram. It barely limps along. The second computer is a gaming PC that's about a year old that is setup with an AMD Ryzen 5 2400 with a Radeon Vega 3.6 ghz video card and 8gb of ram (I really have no idea what this all means necessarily...just passing along the specs). It runs much better here than parallels...but still slow and laggy when editing even basic things (adding basic fade transition or adding annotations and text).

There exists an "Optimizing Camtasia" Lynda course
https://www.lynda.com/Camtasia-tutorials/Optimizing-Camtasia/706931/740430-4.html

Just my $0.02

That is not an answer.

Same problem. Previous version noticeably faster. 2019 seems to be constantly caching to disc. Moved all files and working directory to SD drive. No improvement. Very frustrating.

Just upgraded from 2018 to 2019 today and noticed a huge increase in performing issue when editing. Still Googling any solutions and yet found any.

Here's what I discovered just the other day, The media bin is a CPU & GPU resource hog:::
When I have my Nvidia graphics card enabled.



Below is a screen shot of my media bin and Task Manager. The card is enabled in preferences. I have 20 items in the media bin.
18 .trec recordings and 2 audio files. I also ran tests using just Audio files. And tests with just .trec recordings.



CPU usage varies between 7% and 10%.
GPU usages varies between 25% and 60%.

So up to 10% of the CPU resources are wasted on the media bin alone. There is no media on the Timeline whatsoever.

The GPU aids in timeline playback in all versions of Camtasia. Up to 60% of its resources are accounted for/wasting away.

That's a lot of improperly allocated  processing power.
I run a strong computer.

 4th Generation Intel Core i7-4770 processor 3.40 GHz (8M Cache, up to 3.9 GHz)

16GB RAM Dual Channel DDR3 1600MHz - 4 DIMMs EA - -

NVIDIA GeForce GTX 660 1.5GB GDDR5 EA - -    Supporting   4 Displays

Samsung 860 EVO V-NAND 1TB SSD SATA 6Gb/s           3 EACH


If you have an even lowered powered computer, the hit your resources take may be worse?

I saved the non-project and switched to "Software Only" mode.



Restarted Camtasia and opened the project.
Now the system resources are all down to "ZERO" where they should be.



I was running some audio file "only" tests when I discovered this the other day. I reported it to tech support as such.Not thinking to see if the same thing happens with other media.
I didn't load any still images in today's tests.

Less than 10 media items can trigger the results I posted. The impact is a bit lower with fewer items.
I'll be adding today's findings to my support ticket.

Regards,Joe

That is not the only issue they Have.  I have a post as well about being terribly slow.
i9 Extreme 16 core 64GB DDR4 4200 and 2X Nvidia RTX 2080ti  and a TB m.2 Pro SSD on Raid also everything on Water.
So resource hogging is not the biggest problem. As I compared to the last windows version of Quicken LOL. I think they Interchange coders.

It seems whatever changes they made in the past has been biting  them hard.

I have been playing around with the configuration file yesterday & adjusting few settings. On the Camtasia 2019 system configuration file, there was a setting that limits the editor to only use 1028mb of RAM. I edited the number from 1028 to 2056, and noticed a increase in performance. Also, if you turn off use system sound setting, that also improves the performance greatly.

I am at work right now, but I post the detail of the configuration file when I get home later today.

Hi all, sorry for the late post, so after changed few settings, my Camtasia 2019 (video editing) is now running way faster than my Camtasia 2018. I made a video to demonstrate the steps and hopefully some of the folks will find useful.

And by the way, the performance issue has nothing to do with the GPU you choose (although it does matter a bit if you are using a low performance PC).

Thanks for sharing your findings.

Its interesting but I'm curious?
What does that setting actually do? And how did you determine it should be changed?

I know you said performance increased right after changing that setting . But I'm wondering why?
Was is the setting change that did it, or did something on your computer just happen to  update as you re-started your computer, or did some other event actually cause it?

 I have Camtasia 8, 9, 2018 and 2019 installed on my computer. Every version has the same setting available. And the value is the same with every version. 1024.

I don't doubt you got a performance boost after changing the setting. {:>)
I hope this helps others as well.

Regards,Joe

I guess one way to describe was trials and errors. I toggled different settings and monitoring my camtasia editor memory usage and came down to those the two settings (turn off record system sound and increase file size threadhold).

Turn off record system sound wasn't a big deal. As for File size threshold, that is for how the will be temporarily stored on disk in terms of byte storage, and after some Googling people suggest it is okay to increase the limit.

For me, did those two things made a huge performance improvement on my editing. Like I said, those were my findings so I can't guarantee it will work for everyone, but it is worth to give a shot I guess as you can always reset to the original settings.

I just downloaded the update and am rendering my first file.  
My computer is PINNED at 99% and the rendering time is SLOW if not the same as the previous version I just replaced less than an hour ago:



What exactly is going on here?
BTW...I've read the previous postings.  I'm disappointed that you have to toggle system parameters in order to accommodate this latest version of Camtasia.  I've never had to do this to optimize performance. 

What exactly did you guys at Techsmith do to this thing that makes it lag like this?

Same thing, but working with TechSmith support and we may have found a solution. Added to this thread: https://feedback.techsmith.com/techsmith/topics/camtasia-2019-freezing-and-slow-editing
