Snagit is Painfully Slow on Mojave

  • Updated 3 months ago
I purchased Snagit to be my go-to screen capture tool, but because it is so slow/clunky, I find myself using the built-in tool on Mac or Nimbus.

Just now, I captured my calendar and wanted to blur my meeting details. This required I created 10-15 small blur boxes, which seemed simple, but I had to wait after each one for it to register and display the blur. Also, because it doesn't display the blurred area when dragging, it often is off, leaving me to have to adjust each box, which is slow and unresponsive as well. Do this took over 10 minutes.



A few other examples of where Snagit lags is when I try to adjust the canvas, using the vertical and horizontal slicing tool. 

I wish Snagit would separate out the video features or allow one to disable elements to make it a lighter, quicker tool. 

My iMac has 32 GB of memory and a 4 GHz i7 processor, so it should not have any problems. I don't get this kind of lag with Photoshop or Illustrator (even when they're open together).

If you have photoshop, why are you doing the blurring in Snagit?

Curious as to why you'd go into Photoshop. I guess it depends on your workflow, but I always work in .snagproj files with all the various floating and non-destructive attributes (callouts, arrows, stamps, etc ) then save as PNG for my output file. It means I can go back and edit the original .snagproj file at any time and output a new PNG. I can't imagine how going into Photoshop would do anything other than completely disrupt and break my workflow. Am I missing something?

Might be a miscommunication. I don't use Photoshop for things I can do in Snagit. Another user asked me why I don't use Photoshop if I have it. Sounds like I have the same workflow as you.

Simple, several things. For one, I’ve been using Photoshop for a gazillian years so I know it and I’m fast with it and I can do a lot more than you can with Snagit. I also find editing in Snagit a lot more trouble than its worth but if you know what you are doing, Photoshop is much much faster. For arrows, circles, and things like that, Snagit is fine. Also, if my computer is on, I probably have Photoshop running so there is no break in my workflow.

A gazillion years of experience helps! Personally, I can spend an entire morning just trying to figure out how to change the contrast in PS.

I'm not fantastic with Photoshop, so it seems overkill for basic tasks. I only open Photoshop when editing photos or when something requires better output. I also want to limit the number of programs I have open and a Snagit-like tool is more fitting for my everyday use. I'm looking for something lightweight that is great at it's core features.

I agree, SnagIt 2019 for Mac IS painfully slow on macOS Mojave.  When executing a Cut Out operation, the lag in setting the start line and then highlighting the area to cut out is extremely awful.  I don't remember SnagIt 2018 for Mac being this bad.

I am having the exact same problem. I'm using Snagit 2019.1.1 on Mojave 10.14.3 and the Cut Out tool is so slow, laggy, and jumpy, it's nearly impossible to use.

Hi Darek,

Sorry about this! We're working on improving the performance of cutout.

Hi,

We just released 2019.1.2 which has some really great improvements to cutout performance. It should be much easier to use, and we're working on making it even faster.

I'm on Mojave on two different machines (a 2018 Mac Mini and a 2017 Macbook Pro) and I don't experience any of those lags. I just tried taking a screenshot and drawing a bunch of blur boxes over it and it was totally without lag.

I'm not being contrarian; just pointing out my experience. Maybe there's something else going on, like some other app conflicting with Snagit or whatever. Try turning off things like mobile sharing. Also, turn off scrolling capture. (These are things that probably run with additional side processes that might cause conflicts.) FWIW, I have "scrolling capture" disabled, yet I can still do scrolling captures, so I don't know WTF that's all about.

Interesting. I'll try turning off other programs like you suggested. My image was from the iMac, which I believe is Retna 5K, so that makes it a larger file than if on a regulars 1920 x 1080 monitor, but I'd imagine your MacBook Pro has to be retna, right?

Macbook Pro is retina, plus I have a 32" 2k monitor attached. No problem on either. Mac Mini has a 27" 4K monitor plus a 24" 2K monitor. No problems.

Hi,

I just tried blurring a massive image and ouch, that's no fun. Unfortunately removing video or other features from Snagit wouldn't improve the speed of things like blur. This is a problem we want to solve and we're looking into various approaches to speeding this up.

Appreciate you testing and following up! Hope you're able to find something that will speed it up. Also, when I mentioned removing certain functions, I wasn't saying those would help the blurring situation, rather, just improve the overall "lightness" of the software.
