Why is Camtasia Studio 8 so slow?

  • Updated 3 years ago
I just tried a demo of camtasia studio 8 (8.0.4) on my brand new Intel i7 processor and was surprised that its about 1/3 the speed of my 3 year old i5 processor running camtasia studio 7.

I tested a 4 min screen video on both computers with two edits in the file cutting the final video down to 3m 10s, the first generation i5 pc converted the camrec to wmv in 39 seconds. The new third generation i7 pc converted the camrec to wmv in 2 min 16 seconds.

Oddly enough the numbers are closer if the video is converted without edits but the older i5 computer is about 10 seconds faster than the new i7 computer at 39 seconds and 55 seconds respectively.

BTW - I decided to load v 7.1.1 on the i7 and found it compresses the video in 1/2 the time (1 min 4 sec) as the same video takes in v 8.0.4 (2 min 11 sec). I used the 5:15 min 7.1.1 getting started sample video for my testing.

computer specs:
hp envy dv7 i7-3630QM, 12 gb ram, 1tb disk, intel 4000 graphics, windows 8
home built, i5-760, 16 gb ram, 2 - 1tb disks, 2 - ati 5770, windows 7 pro

These kinds of tests are tricky. It's normal for the 2nd run of any test to be faster than the first, because you'll get more cache hits.

There are many other differences between version 7.1.1 and version 8.0.4 that could also account for the difference in speed. Here's a few:

1. Camtasia Studio 7 records at 15fps by default. Camtasia Studio 8 records at 30fps by default. So CS8 is processing twice the frames, which gives you a smoother recording, but also may take longer. For an apples to apples comparison, you'd have to use the same source video on the timeline in both CS7 and CS8.

2. Camtasia Studio 7 performs all scaling (at 30fps) in software, using intel optimized instructions. Camtasia Studio 8 performs scaling on the GPU by default, which is usually (but not always) faster. The speed depends on how quickly your system can transport frames from RAM into VRAM and back again, and this can also be affected by your video card settings (quality vs. speed, etc.). Camtasia Studio 8 also has a software renderer, which is similar to what Camtasia Studio 7 used. To force the software renderer to be used, you can uncheck Tools > Options > Use GPU acceleration if available. After toggling this option, you must close and reopen your project to reinitialize the renderer in software mode. For an apples to apples comparison, you'd have to use software rendering in CS8.

3. Dimensions. The dimensions of your source video, the editing dimensions, and the production dimensions can all have a big effect on the speed of the render. This is true in both Camtasia Studio 7 and 8. For an apples to apples comparison, you'd need to hold these contstant across both versions.

4. Production format. You mentioned WMV, and we haven't changed the way WMV files are compressed between Camtasia Studio 7 and 8. For an apples to apples comparison, you'd need to produce using the same format, and same settings in both versions. But it sounds like you're already doing this. For what it's worth, the MP4 output is multi-threaded in both CS7 and CS8, which means the compression would take advantage of multiple cores. I don't know your reason for choosing WMV, but you might see a performance boost from switching from WMV to MP4.

Hope this helps.

Dave, his i7 and i5 are not the same computer.
The i7 i think it's a laptop and the i5 is a desktop.
Obviously there is some problem, the i7 MUST be faster.

Randy, try disabling the GPU acceleration in the i5 and test it again...
If doing this, the i5 gets slower than the i7, the problem is that the i7 doesn't have a dedicated graphics card.

Sorry for my bad English.

Im paralized with my current dual core windows 7 computer when editing a 1 meg file so im upgrading my hp allinone to the sony tap 21. Link at bottom

Im trying to decide between i5 and i7 in my next new comupter.

Im buying a sony tap 21 config with
Intel® CoreTM i5-4200U (1.60GHz / 2.60GHz3 with Turbo Boost
8GB (8GB x1) DDR3L-1600MHz
Intel® HD Graphics 4400

Money is not growing on tees but ..... Would it make a big differnce to up grade
To the i7, 16 gb or the Intel® IrisTM Graphics 5100 card

If you think any of theseup grades make real sense please let me know.

Hi all,


I'm experiencing the same problems. I need to render videos usually about 700 MB and around 30-45 minutes long. It takes several minutes to render one % of a video no matter what format I choose.


My setup is this:

i7-4702HQ 2.20 GHz

16 GB RAM

512 SSD

...and QHD resolution (3200*1800).

Camtasia 8.3


HOW make it quicker?


Thanks a lot for any advice!

Update: Updated to Camtasia 8.4 and no change...

Make sure the files you add to your timeline exist on the local drive, where you can get fast I/O.  If the files you add to your timeline are stored on a network drive, you'll be doing reads across the network during timeline playback and production, and this can slow things down significantly.

There are many factors that affects the performance of the timeline.  The most common cause we see is the use of a network drive, thumb drive, or other drive with slow I/O.  Next is the use of very large dimensions.  The smaller the dimensions, the faster the export will be.

Hope this helps.

I talked it through with the tech support and yes, high resolution is the cause.
I need to record on my laptop, which has res 3200*1800 so I can't really make it faster. I cannot change the resolution to anything lower as it makes everything blurry...

camtasia developers should add intel quick sync video to render videos faster. I don't know why camtasia developers don't support intel quick sync either they don't want to support or they never heard of intel quick sync. it take for a long time to merge audio and video in 480p in cs 8. I don't like other software cyberlink ect because it lack some features,and  I don't like output settings but the advantage of cyberlink is that it support intel quick sync and can render videos faster. I like the output setting of cs 8 but I don't like rendering so slow even 4th gen i7 - 4510U, geforce 840m, 8gb ram. hope cs deveopers will support intel quick sync in cs 9. thanks

I very wisely kept my Windows 7 laptop, where I am still using Camtasia 7. I'm using Windows 8.1 and Windows 10 on my other devices... one of which I purchased *specifically* for video production using Camtasia 8+. I have found that I can render the same video in 20% of the time on my Windows 7 using Camtasia 7. Yes, you read that right: I'm not talking "seconds" difference... Camtasia 8 takes 5x longer to render the exact same video. That's the different between 5-10 minutes and 30-60 minutes PER VIDEO.


I have also had problems using Camtasia 7 on Windows 8.1. It will not capture the whole screen (it *appears to*, until I am in the Camtasia studio, where I discover about 20% of the right/bottom is missing.)


I have tried numerous different things to get Camtasia 8 to work on my much-newer computers, to no avail. So I will keep using Camtasia 7 on my Windows 7 laptop... until it dies. Then I will probably migrate to a different video editor.

I recently purchased a new laptop to speed up rendering Camtasia projects. Initially it sped things up by a factor of about 6 times. But the last two versions of Camtasia have caused it to become unacceptable slow. My current laptop has an i7 with 8 cores, and watching these there is only 16% utilisation of the CPU's. All are active so the threading  is working. What is causing the  problem here? The laptop has 16GB Ram so there's enough to buffer the entire project.  The problem is the same whether GPU is switched on or off.  I've seen so many reports here of a similar experience, and guess it's time for some serious rethink on the rendering process.

Hey folks. With the new release, version 9, Camtasia is 64-bit and has had some significant performance increases. Would love some feedback on if it is faster than v8 on your projects. Thanks!

Thanks for the info. Just downloaded Camtasia 9 and attempted to test the speed. Unfortunately, all of my Camtasia projects (more than 100 of them) are in Camtasia 7 and 9 cannot open them. I hope there will be a way to upgrade a version 7 project directly to version 9 as I would not look forward to having to double-upgrade every project.

at present, you have to upgrade 7 to 8, then 8 to 9

Hi Mrbobmac,

Maybe you could help me understand EXACTLY what you are needing. I know you said you want 100+ projects to open in V9.

Are these 100+ projects that you are actively using, editing, updating, etc? For example, you work with each of these projects on a regular basis?

Are there components in those projects you don't want to lose - like beginning title slides, callouts, groups, etc. Or, you just want the project, including edits on the timeline, in its entirety?

Is there an expectation that V9 will give you some improved/automatic way to work with those projects? For example, if you have a lot of callouts in your projects, and you want to automatically update all the callouts to a new V9 callout style, color, etc.

Or, is there another reason why you want those projects to open in V9?

If V7 is working for you, what draws you to the idea of moving to V9? And, what would you expect your V7 project to look like if opened in V9? The same as V7? Or actually different somehow?

Any insight into this matter will be of a great help.
