Camtasia 2020 Slow Render Speed

Jason with TechSmith Support suggested I post this feedback here to share with developers and the community. He is also passing on my feedback to the powers that be. I have noticed some major rendering speed issues with large projects. Yes, even after drivers have been updated. Below is my last feedback to him.

By the way, I have always said and continue to say, TechSmith Support service is some of the best around!

==========================
Hi Jason:

That is interesting. I have always had my GeForce set to automatically download drivers and notify me when they are ready to install. I must have accidentally skipped this one. However, some improvement, but not much. The GPU definitely doubled. However, the rendering time still was close to the same amount of time as previously. I tested on the “NAME OF CLIENT'S VIDEO” project.

Apologies, I didn’t think to time from the very start of the rendering, from 0.0% to when it hit 100%. I would guestimate that took approximately 10 minutes from 0% - 100%. Then I did look at the time when it hit 100%.

[When] it hit 100% was at 9:43 and did not complete the render until 10:02, nearly 20 minutes later. So, the 46:17 minute video took approximately 30 minutes to fully render. Is that appropriate? (Maybe, is it time for me to go from 16GB RAM to 32GB RAM?)

My feedback/concern for TechSmith is when a user sees this image at 100%, most users would think it is finished rendering. They would not expect it to take another 20 minutes to fully render. 9:43 – 10:02. It gives an impression something is wrong with the system. Maybe something to consider for future versions.

Of course, I’m not a techie, so maybe there is something I am not understanding as far as the nuts and bolts of hardware vs software. :-)

With all my best,
Naomi
==========================

While rendering from 0% - 100%.

Once it hits 100%, hangs out here for 20 minutes.

Naomi, something that might be helpful is for you to share the specifications of your machine. 

You mentioned 16 GB of Ram and a GeForce GPU -- what kind of GeForce, specifically? 

What about processor? Are you using a hard disk or solid state drive? GPU?

Like you, I'm not a SME with the technical details, but these details generally help identify bottlenecks. 

20 minutes to go from 100% to done is *extreme*.

I provided to TechSmith support with a full DxDiag. The only suggestion was to update my driver, which apparently had not been updated. Something I normally keep on top of. However, that did not change things.

I think Joe recently discovered that Camtasia never appears to use more than 3.2 GB - just like a 32-bit memory limitation. There's something going on here and I think it's only curable at Tech Smith's end. 
It's as if they compiled a 64-bit program (which should be able to address many pita bytes and yet none of us can get it to address more the 3.2 GB or RAM.  I'd volunteer to fix it for them - but they'd probably nix providing the source code. 

Could you do me (us) a big favor and re-render that project again?
In prep for the second run, turn off Windows disk caching to any/all SSDs. [Device Man, drill down on Disk Drives, and rt-click on each SSD and in the "Policies tab" - uncheck write caching.]
In run#2, in addition to Task Man, also open Resource Man and monitor all disk activity.

If you turn off disk write caching, I think your first 10 minutes may take 11, but the final 20 may diminish to near zero, just a guess.

FYI, I didn't say Camtasia never exceeded 3.2 GB or RAM usage.
I have 32GB so I don't have any reason to monitor it.

I did mention it hadn't exceed 3.2 in a test I had run. I was surprised by that and still am.

Out of curiosity, I opened task manager on a project I'm currently working on. I hit 4.5 GB of RAM usage.



In my mind, thats seems low and inefficient. A waste of my systems resources.

Hi Ed, I have rerendered projects so many times, I'm kind of done with it. I need to move on to my work. As far as your suggestions for turning off disc write caching, especially with the warning of losing data, that makes me extremely nervous to do and not sure that is the route I would want to take.

This is not something TechSmith Support suggested doing, so again, that makes me nervous.

Hi Naomi - just to set the record straight as the warning below states you are at greater risk by using a write cache. Do you see that now?
You won't lose even one "bit" if you try it for a week - all write cache off. If you have NVMe SSDs, you'll notice a little performance increase, SATA SSDs a little decrease.

Okay, not sure what type of SSDs I have. I'll research this further next week, after I complete two other projects I have in the works. Thanks for clarifying.

Ed, FYI, finally tested this. Made absolutely no difference. I'll just upgrade RAM from 16GB to 32GB when it's safer to go outside. Take it to the shop and have them do their magic. :-)

I've also noticed a big increase in ram use. I had 16gb of ram the other, I just upgraded last night so this isn't an issue any longer, though I have wondered if they changed something.

Opps I forgot to add I upgraded to 32. I used to have 16gb.

Your screen shot shows Camtasia is only consuming  5.8GB of RAM.

Yet your system is consuming 98% of installed RAM.

I don't see how Camtasia was an issue to begin with?

Do you have any screen shots of Camtasia itself consuming 12GB's or RAM or more?

Oh no I acknowledge I have other processes eating up ram like chrome as you can see. I've just never noticed Camtasia using almost 6gb of ram. I needed to upgrade anyway, but seemed like this was something new with Camtasia I thought. I'm not really sure what's considered a normal range of memory for camtasia.

Heres my point..........

when systems RAM is reading 98%.
You can bet the farm Windows is caching memory to disk.As that process kicks in, the original Apple computer could probably outperform yours.

The crashes you've been experiencing are probably nothing more than RAM crashes. I've experienced RAM crashes in Premier Pro with 16GB. I upgraded to 32 for that reason.

64GB's is overkill for most.
If you were seeking to record yourself using a 3-D application like SolidWorks at 4K resolution.
SolidWorks may very well tap into all that RAM. Still ,theres few justifications from where I sit to purchase 64GB.   

Now that you've installed those 32GB's.
If system memory is still becoming saturated.
You've got a major memory leak somewhere. The source needs to be tracked down and addressed.
Or you've got a RAM hungry application open at the same time. One thats bringing the computer to its knees.
Either way, with 32GB.
RAM should be the least of your worries. Under most circumstances, you should have about 25GB or so to spare.

If you have a hidden file in the root called "Pagefile.sys", you can see if Windows is using it for RAM. If you have 16 -GB Ram, it should be about 16-GB, however if it isn't being actively used it's size on disk is 32K or less.  I canned my PageFile.sys  years ago, but I have an indexed image file, RAMDisk.img that . . . see here:

This is my Ramdisk's image file - currently has 2.13 GB in use but can grow to 16.3 GB. I should also add that once Windows no longer needs to swap, it's size will return to near zero.

Well  everyone,

Camtasia 2020 just utilized over 12GB of RAM on my computer.
So for now, I'm sticking with 32GB as my recommendation and the sweet spot.

Hi Joe!

I'll be honest ... I've never actually seen this before and am in awe of the usage! I personally tend to see it sticking right around that 3-4GB of usage on most of my systems (my personal computer is a little different and RAM usage is actually rarely above 3GB). I'm mostly curious what Camtasia was doing at the time of it using 12GB, did you have a big / intricate project loaded?

It was this project posted to forum the other day  Camtasia 2020 rack Mattes

It was complex, I selected and un-grouped the entire project one time. Then dragged some groups closer together so they would come into view. Deleting empty tracks. Several other groups remain intact.

What you won't see in this screen shot are the multiple track mattes that are no longer applied. Removed automatically by Camtasia through ungrouping.

There are still several groups remaining on the timeline.


It was during the  rendering process that I hit the highest usage. I thought I was going to hit 13 having hit 12.9 more than once.

I ran a fresh render of the same project, no edits applied, no nothing. Just open Camtasia, the project and hit Render. I peeked  6.9 tops.

Hi Naomi!

I just wanted to pop in to let you know that I'll be updating your ticket with a couple things to see if I can help mitigate some of the issues; I looked over the ticket and would like to add a bit more to it.
Thanks for posting this here!

Robert -  

". . . I'm mostly curious what Camtasia was doing at the time of it using 12GB . . ", me too.

The best way to get "The BIG Picture" would be to track activity via Mark Russinovich's "Process Explorer" - he catches everything and in this case, the parent-child relationships among threads. A great tool.

He has many YouTube videos on how to use it, search  "Mark Russinovich Process Explorer"

I don't care what you were doing, I'd like to know what Camtasia is doing. Were you able to watch all the child processes that Camtasia creates?

Well no Ed, I generally don't dig that deep into the processes. If my computer is running well and isn't crashing, I don't sweat the details all that much.

I don't save my project often.I let autosave do what its designed to do.
At times,that may put a tax on RAM usage with complex projects.

I've had RAM creep up in Premiere Pro over long complex sessions as well. I attribute it to the nature of the beast.

I had been editing for quite some time in this instance, and nothing more.
That video is a compilation of more animations running simultaneously than one usually runs. Coupled with masking/track mattes.
I hit just shy of 7GB with a fresh re-start of the project.
