Extremely slow performance on Mac of Camtasia 2021

    My best guess is that your files in Dropbox had local copies on your system.  If you are seeking around in Camtasia and the files are on the web, network issues can disrupt how fast we can read the files.  Since we never keep the full files in memory, but read the data when needed, we do not recommend using Camtasia with files that are on an external drive.  So perhaps after your system upgrade, the files that used to reside locally are no longer there?  I use DropBox as well to share files between different computers (example, work and home). I have dropbox set up on each computer to keep the files locally as well as in the cloud.  I am not running Big Sur though, so I cannot say for certain this is the issue.

    Leif, thanks for your reply.

    It does not make sense to me. I created a brand new file, with all source files located on the local hard drive. (See separate ticket). So I started from scratch. New empty Camtasia 2021 file. Local source files in my Documents folder. NO difference at all. It looks to me as if something is wrong with how the files are kept in memory.

    Here is what I am seeing: when I load the files onto the timeline, the first time I scroll forwards in a clip, it looks fine. Then I need to scroll back and everything slows down to a trickle.

    I realise that this may not even be due to Camtasia, as this started to happen after my emergency upgrade to Mac Big Sur 11.3 that was strongly recommended today. But I would like to know if there is something I can do about this.

    Both 2020 and 2021 show the same slowed down performance. And it happened after the update. I cannot afford to stick with the old OS because it would expose me to a serious threat. I work in IT, I know my business - saying that not to sound arrogant, just to indicate that I know what I am doing.

    Anything you can think of I can do? Clear local files? Caches?

    I restarted 3/4 times after the update (including a cold shut down and re-start).

    Not sure what else I can do. Do you have similar experiences with this latest update of the OS?

    What hardware are you on?  Intel or M1?  I am not running Big Sur or using the new hardware so I cannot say if either of those is the cause.  Your best bet is to submit a ticket to Techsmith tech support and see if they can help you resolve your issue.  As you say, it seems to be due to a change in the OS.  If we can duplicate your issue on similar hardware it will be a lot easier to track down the cause.

    Hi Leif,

    Yeah, I have done that. They had me empty cache and temp files. It was a bit better but not by much.

    I am on a Macbook Pro 14 (2017) with a 2.8 GHz Quad-Core Intel Core i7 processor, 16 GB 2133 MHz LPDDR3 memory, Intel HD Graphics 630 1536 MB.

    Last night when the suggestions did not really help, I closed the lid on it and just now opened it and saw a notification that the laptop had been shut down due to an error. Just restarted. Will give Camtasia another try and keep you posted.

    OK, here is an update. I have done extensive system maintenance, shut down the computer for a good 15 minutes. Then restarted, opening an existing project in Camtasia 2021: same story. Everything works when playing at normal speed. But when I need to edit and scroll through the clips, going forward is still OK but from the moment I scroll back things start stalling.

    I then created a completely fresh Camtasia file. Added local files, short clips.

    I am unable to sort by name until after I sort by the default: media type. Cannot change to name right at the beginning. Then I add the clips in ascending date order.

    Same thing: as long as I go normal speed there is nothing wrong. First time I scroll forward through the clips, everything fine. As soon as I stop and scroll back to find the right spot to ripple delete, trouble starts, images start stalling and halting. Regularly, Camtasia jumps back to an earlier clip, completely unrelated and I have to start scrolling forward again and things slow down again.

    I don't remember this from before: the thumbnails of a clip come up slow, the do not show for the active clip, but they do show for the one before and after.

     

    I don't know. I am going to try and roll back to Big Sur 11.2 which is not that easy. And then see what happens, if I manage to do it. This seems to me related to the video rendering and I have no idea if this Camtasia specific of OS specific. One I do know is that this sucks. I was supposed to deliver 5 days worth of footage (resulting usually in videos of 15-20 minutes) and after 2 days I have 2 painstakingly created videos that are not even finished and cut to the right clip sizes.

     

    Anyone who can help is most welcome to comment. See you (hopefully) at the other end of the downgrade.

    Arnolda,

    I am experiencing something very similar. 

    I upgraded from 2019 to 2021. Now everything in both 2019 and 2021 is nearly impossible to edit.

    I'm on Mac 11.2.3 on an Intel

    Beyond frustrated.

    That sucks for you, Julian, but I am happy that I am not the only one with this issue.

    I used 2019 for a short while on my older MacPro big machine, which runs on High Sierra. Which is 10.13. I had used much older Camtasia's before but they kept crashing. 2019 was running fine, in terms of editing, but my old machine just does not have enough power for my current projects. So I then decided to use my faster 2017 MacBook laptop. Initially I wanted to use my 2019 but I ran out of licences. So I bought a new one for 2020 (and 2021). I thought it was worth the money and it still. might be once this performance issue is solved. Naturally, when I received word about version 2021 I upgraded Camtasia. Still fairly fine. Until I upgraded to Big Sur 11.3. I was on the same version as you, before that. The security update to get to Big Sur 11.3 when installed last week was really crucial for my other work. I'd suggest you keep a good eye on your machine, because when it is hacked with this new threat you will be paralysed. If you already have issues now, maybe doing the OS upgrade is the lesser of the two evils.

     

    But I do believe there is more to this. There must be something going on in the two last Camtasia releases with memory management. It was always such a wonderful program and I would love to keep working with it. 

     

    Good luck with your projects!

    This has to be maddening.  So you both are running to BigSur 11.2.3 or later.  You both are running on intel hardware.  I wonder what else is involved.

    Do either of you use encryption on the disk where the video media lives? 

    Have you installed any other software on the machine recently? (Many years ago, I remember one piece of source control software that hooked into all running software including Camtasia and made Camtasia very unstable - we found that be looking at the crash reports and looking at the libraries loaded into the process at the time of the crash and finding something common and not part of the OS in the crash dumps).

    Camtasia 2019 and Camtasia 2021 do not share or interplay with each other in any way (other than when Camtasia 2021 is first installed, it will copy the settings and custom data that Camtasia 2019 used so you don't loose work between upgrades).

    I would like to be able to find a machine set up the same and see if we can reproduce the problem and determine the root cause.

    Maddening it is, Leif.

    I had no other software installed at the same time as the security update to 11.3.

    Camtasia has our system reports and I have not heard anything being obviously wrong in there. In order to do a full replication you'd have to have both the hardware and the software setup. This will not be easy to do. I am an IT worker myself, albeit not in the video business, but I know that other programs can influence performance of other apps. In this case I really don't know where to look.

    I have followed all directions and both upgraded local projects to 2021 and started with a fresh document. The behaviour is predictable. As long as you scroll forward in the timeline or run things in real time, there are no issues. Of course, we all understand that the reason for needing apps like Camtasia is not just watching the footage, but editing it. And it seems a basic function to have a need for being able to quickly scroll back and forth to determine where a clip must be cut.

    I saw no difference between local files saved as stand alone and local files not saved as stand alone.

    What I can say with certainty is that I started my current project with the source files located in a synced Dropbox folder on my mac. Never any issues with the older Camtasia I used. When I upgraded to 2019 I got notifications that the Camtasia project file must run on the local disk. I was however still able to use clips in a synced local Dropbox file.

    When I upgraded to 2020 on High Sierra and Mojave there were no issues. Then moving to my newer laptop on Big Sur 11.2 I started to have issues. So I upgraded to 2021, thinking: newer is better. The rest is history. Alas.

    I hope we will be handed a solution soon. I am fairly certain that it must be in memory / cache management. Cannot imagine what else it would be. I have 3 machines for editing and the most apparent issues happen on the newer one.

    Are you willing to turn off DropBox for a bit and then open the project in Camtasia and see what happens?  There was a time, with a version of DropBox and Mac OS (not 11, but I think 10) where DropBox syncing dramatically slowed my computer, even when working with programs that were not using files in DropBox.  Dropbox was doing something in the background that made my disk very unaccessible. At some point either a dropbox update or an os update fixed the issue and I was again able to leave DropBox running all the time in the background.

    I often work with files in Dropbox and as long as they are synced and available locally, there is no issue. The issues in Camtasia occur when editing files that are not stored locally since network speed can then interfere with getting data at an acceptable rate.

    Something you could try is to proxy your files (right-click on the source in the media bin and choose proxy for the media.  The file will be read and a proxy file written out.  The proxy is a lower resolution version of the file with no temporal compression.  It makes ending much faster at the expense of some disk space to store the proxied media.  When exporting, we never use the proxy so you get full resolution even when using proxies while editing. 

    If it turns out the Dropbox, or some other service is making reading data off of the drive slow, then proxies won't help substantially (a little perhaps because less data to read).

    I understand. However, I use Dropbox's SmartSync so that only a few folders are kept in sync.

    It won't make a difference for this issue, I dare to state, because there is currently nothing to sync and also I work with the files locally. Not to be confused with local Dropbox files. I have copied the files into a local folder and then worked with Camtasia.

    Also, the computer I had no issues on was my old MacPro with just 150 gb of disk space. The new laptop is exclusively dedicated to video work and has 4 times that space.

    Thanks for brainstorming, though. Who knows, we might find the cause. Hopefully fast. It seems to me that the behaviour is easy to test: just open a project, scroll forward until you need to scroll backwards and you will see it. I filmed it on my phone and sent it in to Joe at Camtasia. Did it that way to make sure that screencapture itself was not interfering. It is very clear. As of version 2020 there is some 'jumping' and halting when editing. As of version 2021 it takes ages, with the dreaded beachball appearing, to reload the video and getting to the part where a cut needs to be made is more a gamble than precision.

    And as a by the way, here is another maddening thing:

    in 2021 when I right click a clip to do something like ripple delete, just when I want to select an option the right click menu disappears. I have to repeat the right click like ten times to be able to do the selection. Same with the 'File>Save as' menu. I don't understand what is happening.... :(

    To be clear, 2020 is running OK on the same machine (so same hardware and OS) but 2021 is not? 

    I missed that part when reading previously.  So something is slower in 2021 than 2020?  That is unexpected and surprising but another clue.  I don't see the issue, but I'm also running on OS X 10.15.7.

    Same issue in both version since updating to 11.3.

    And to be clear, when the issue existed, DropBox really made my machine entire machine sluggish.  At the time I tried a number of things to troubleshoot the issue.  Turning of DropBox running in the background was the only way to get my system back running well.  I have only ever had one specific folder synced with DropBox. (Note I'm not faulting DropBox, I love it and can't image not having it. There was a serious issue with it in one release though - or at least with one OS version and Dropbox version combination.)

    It says 'employee' in your profile. So, maybe touch base with Joe who has my cell phone video of the behaviour I am seeing. By now, with Camtasia on 3 machines with different OS's I am losing count of where I see what. But the combination of 11.3 with Camtasia 2020 or 2021 is not a good one. Almost unworkable unless you know how to be reaaaaaaalllly patient.
