Camtasia is locked on my CPU and using at 30 out of 34%. RAM is at 40%.
As you can see, it even happens with absolutely nothing imported into the clip bin or onto the timeline.
On a side note, another issue with camtasia studio is it slows down or even freezes if too many files (audio files in my case) are put on the timeline. I make 12 hour long "Nature Sounds" videos, and the more audio files on my timeline, the slower camtasia gets, and at a certain point it just freezes and shuts down. I know there are limits, but sony vegas pro 12 can handle the same workload, and then some, without crashing, it still slows down a bit, but not nearly to the degree that camtasia does (at its worst, I had to wait for about 10 minutes or so for the project just to load, and then when I tried playing it back, it would crash). For example, if I use a 20 second audio clip and loop it to fill the entire 12 hour duration, then this is where camtasia starts slowing down and/or crashing. If, for example, I take that same 20 second clip and loop it to the length of about 15 or 20 minutes, render it, and then reinsert it into my project and THEN loop that 15 to 20 minute clip to fill the 12 hour time slot, then the bogginess and freezing go away. Just wanted to mention this issue/bug just in case tech support wasn't familiar with it yet.
I wish computers and software could diagnose themselves, it would make using them so much easier.
After I update to 8.4.0 it now keep popping up the tutorial video and it crashes it popped up a messaging saying file is inaccessible or corrupted. I tried everything from here and uninstalling reinstalling. nothing is working.
If i open a camtasia of my recording it doesn't crash BUT when I drag it to Timeline to edit it crashes right away. if i open Camtasia regularly it crashes on playing the tutorial. something it plays the whole thing then crashes.

I've been told in the past by support that various projects crash because they're too big. They suggest doing all the audio editing in an external program because the XML file keeping track of edits get too big. I do that and then it's the video edits that start causing the crashing. If I'm going to edit both the video and audio before bringing them into Camtasia, it seems like the tool may be a little redundant. Great screen capture though!
During the time I've written this response, Camtasia has crashed 3 times while trying to export a 15-minute movie.
I know ranting doesn't change anything. Techsmith is convinced that it's always user error, not memory leaks or bad code. I'm starting to migrate to Screenflow on the Mac. I don't like the interface as much but certainly don't have all these crashes. However, it's like losing an old friend if I have to give up totally on the program.
PS: Upgraded to 8.4.1, opened the program, opened the file I was working on. Crash.
also, breaking large, complex projects down into a series of 5 minute sections, and using the Library, can also help
these tutorials may help if you are unfamiliar with exploiting the Library ...
I have found that the undo stack can also play a role in crashes [just my opinion here]; so, after doing a bunch of edits, I'll save, exit, re-launch, and re-load; that way, I start fresh with a minimal memory footprint [I monitor the CS process memory with Task Manager] when memory in use approaches 2 GB, I'll execute a save-exit-relaunch-reload
I often push Camtasia well past its design envelop, and the above techniques have continued to let me accomplish many large, demanding projects
NO regular crashing is acceptable for an expensive professional program like this! I am guessing a bit, as I am not a programmer, but I think the coders need to use something like:
it's free for open source, but Techsmith have plenty of our money to pay for it ;)
"LibreOffice joined the Coverity Scan service in October of 2012. Since then, they have leveraged the free development testing service to scan more than 9 million lines of code, and identified more than 4,700 critical defects. To date, they have fixed more than 2,100 high- and medium-impact defects, including null pointer dereferences, resource leaks and memory corruptions, and their defect density has dropped from 1.11 to 0.84."
A very clear cut vulnerability detected: I used an mp4 (Camtasia 8 generated!) in the Camtasia 8 timeline, constant crashing. I then got rid of it and used jpg and wmv only, no crashes at all.
Hope this helps someone! I was ready to strangle something myself...
Thanks for letting us know about your test. .mp4 may be the culprit, and certainly something to try if you use .mp4 in your Camtasia projects. I do not. In my case I suspect long .camrec files cause crashing (and moreso the further you get into the editing, splitting, stitching, callouts, more callouts, effects, audio, etc). I don't always get crashing, but my latest recording was over an hour (1h:25m or so). It started slowing down dramatically before I was about halfway through editing. It began crashing when I was about 2/3 of the way through. The project began loading SLOOOOOOWLY (over 3 minutes to load up the project after a crash). It crashed 3 times before I finally finished that project.
I'm a professional video editor. Normally I edit on Final Cut Pro. But I LOVE Camtasia for what it does and does VERY WELL!!! However, the FREQUENT crashing is silly. I don't have a solution, but to get by, I do have a hack of sorts:
1. Hit SAVE regularly, especially after making significant changes (significant may mean lots of detailed little changes not necessaryially moving Lots of big chunks)
2. QUIT - Yeah, Save and Quit the program before Copying and Pasting large portions of your sequence or before exporting the project.
These "fixes" should really be unnecessary, but if you value the hair left on your head, it makes sense.
Between hangs and crashes, editing has just been a nightmare so far.
Judging from how the software behaves, it is quite obvious there was close to no attention paid to memory management, which really is a shame for a video software.
Just stop adding features and please review your code.
Edit: My bad, I have talked too fast (out of a lot of frustration though). I finally realized that my cuts were dividing groups rather than producing stitched clips, which eventually resulted in memory issues. Ungrouping and stitching did bring the editor back to a more stable state.
Now, I understand the limit inherent to a 32 bits apps, and I hope the x64 version is underway, but I have troubles understanding how the memory footprint suggests that everything is live, whereas there seems to be a lot of HD activity (and corresponding hangs) while editing. If that's from a previous attempt to fix the memory problem, it might be that there's still a memory leak around.
i had the same problem, windows 7, 8gb ram, quad-core, etc...
after record screen i saved in camstasia file... it crashes when i render big files... 1 gb or more...
so i record in mp4 after stop recording, but with my recorded files i have to extract the avi file without the things that camstasia add.... to do this, i select the clip and select "file", extract... something like that... and i just render the avi file.
