How much ram is "too much"

Hello Everybody,

I see in the documentation on this Camtasia 20 system requirements page... https://www.techsmith.com/camtasia-system-requirements.html

....that for windows the "Recommended Ram" is "16GB of RAM or more"   

My question is how much more?   For example, if I have 32GB of Ram or even 64GB of ram, can Camtasia take advantage of that much ram -- for a complicated camtasia video with many short edits, for example.

Is 32GB useable.
Is 64GB useable at all based on Camtasia's memory limits.  
I am running Windows 10 64 bit system.  

Thanks!

In most circles, 32 GB is where you want to be at for 4K editing.
16GB isn't much to hang your hat on these days.
Windows 10 will tap close to 4GB off the top.
I lean towards recommending 32GB's for that reason alone. Its great to have overhead available.
I run some pretty hefty Premiere Pro projects at times. Light duty After Effects with dynamic linking. 32GB has served me well. I've never tapped 16 GB in Camtasia that I'm aware of.

I also edit at 1920 x 1080. I like 4K. Its cost prohibitive overall, it takes to much time to process, upload, share,etc. One day it will be much different.


For the most part. 64 GB is overkill for most people.
You may be able to force your computer to load that much content into RAM. But the average CPU will choke on it. Can't do much with it all at the same time. If you've got 50 gigs running, you've probably got far to many applications open.
Unless you've got some mega beast CPU. 64 GB will never be tapped.
Especially by the average Camtasia user.
Well, 3-D modeling software will gobble up RAM. I'm sure I'm leaving other programs out.But thats not the subject at hand.
I'm sure there will be more opinions coming {:>)

Regards,Joe

There are two trains of thought here:

"I'll never need more than 16 GB", which is a self full filling prophesy (Because they never can).

If I buy a MB than can hold 64 or 128 GB of RAM, I will fully populate it to the MAX, I may not know how I can best use it today, but I'll figure out a way.

But even more important today, is to get all "storage" off SATA-3 and onto the PCI bus (16.6 times faster)!  I have a MB that will host 4 PCIe M.2 NVMe drives and you can't imagine how they rock!
Drive #4 is a enterprise 3TB that collects slow-mo seldom used & BU data. Drives #1 & #3 are C:\ and clone of C:\, drive #2 is D:\  - a 2 drive striped set, which comes close to the DRAM speed which is divide into two parts - RAM and Ramdrive.

Technology is finally getting faster than Moore's law allows, don't just watch.

Joe -

No, no example of Camtasia needing even 4 GB.  I normally use a portion of DRAM for a Ramdisk, now in the 16-32 GB range, leaving 32-48 GB RAM available. 

If Tech Smith used RAM for everything (instead of temp folders and files), we'd all be much happier.  BTW, I can read or write (stream/scream) data arrays between Ramdisk and DRAM at a 7-8 GB/sec clip. 

> "My RAM usage tops out at 3.2GB and hovers around 2.9GB."

That's because Tech Smith compiled a 32-bit program in a 64-bit compile without ever re-declaring variables to 64-bit. A rookie mistake IMO.

WOW,you ain't kidding Ed.

As an experiment. I put identical music videos in Premiere Pro and Camtasia.
I stacked them all on top of each other. 20 tracks of 1 video.

I hit the play button in both applications.

Premiere Pro used almost 10GB of RAM.
Camtasia used less than 2GB.



It would seem 16 GB is more than enough for Camtasia?

Ed,

For those of us with multiple cores/threads, does Camtasia make use of those or not?

It has no trouble tapping mine.
Its only a 4 core.



Despite the low RAM usage I'm seeing, I think timeline playback performance is pretty good for what I'm throwing at it.

Paul, 

There are certain activities that are born to be processed in parallel - Fast Fourier Transforms (FFTs) for example and Tech Smith does use them, a lot. "Handbrake" is the best example of using 99-100% of the threads given it. 

Other activities need job #1 to be completed before job #2 can start, etc, etc, etc. 

Re: Camtasia, I've rendered at 94 - 98% for 8 core, 16 threads.  I've also experienced 50-70% while rendering on my older 4 core, 8 thread system. More threads = much more better !
Even if Camtasia can't use them all, Windows can continue to look for the location of my mouse 300 times a second without interrupting Camtasia.
