I'm using Camtasia Studio 8.0.4 for Windows. I've completed several voice over videos prior to this, and using the exact same process, and just now running into an issue with audio stutters (a la Max Headroom) upon playback from the CamProj. I've recreated the camproj from scratch and still am getting digital stutters across the playback and not always in the same spots.
I tried applying audio properties which did not change the outcome, it just stutters without a hiss now.
I've shut down all processes on the PC that I can to allow Camtasia maximum processor power but still no luck.
Please throw me some suggestions as I'm quite frustrated at this point. Thank you!

We did make changes in version 8.2.0 and 8.2.1 to address some stuttering issues during editing. Please make sure you have the latest version (8.2.1, as of today) and if you continue to have problems, please let us know. Thanks.
Dave I have terrible stuttering in 8.4, not in production but makes for painful editing. Thank you!
I am also having stuttering problems during preview. The final published results are fine, but it makes it definitely disrupts the editing workflow.
I also find the stuttering on preview playback extremely annoying, it's impossible to accurately preview with this happening. The produced end result does not stutter at all, but the problem is I have no way of accurately previewing the end result due to the preview stutter. I have to produce the end result, hoping the edits/transitions were ok, then go back and do it again every time I find out the edits needed tweaking.
I'm using Camtasia 8.4.3. I'm making HD content, so 1920x1080 pixels. Fair enough that means a lot of data for Camtasia to handle, but it ought to do it better than this. My pc is decently specified, i7 2670 processor, 8GB ram.

Did anyone find a solution to this problem? I have a brand new computer - i7-4702HQ processor, 500 GB solid state hybrid drive with 8 gb flash, 8 gb ddr3L memory, NVIDIA Quardo K 110M 2/2gb gddr5.
I also had the same issue and have a state of the art pc. Why is this happening?
It's very frustrating and I'm looking into other options for creating content for SCORM because of this. If you have any suggestions, that would be great. I'm currently looking at Captivate.
I've been experiencing something similar with 8.1.2.1327 and with 8.4.3.1972.
It only happens every now and then and never when I am testing, only when the recording booth is being used by our company's staff.
Going to update to 8.4.4.1859 and see if it happens again.
I am experiencing this today. I make a sample clip to test the audio, it sounds fine. Then I do a 20 minute recording and there is stuttering all over the project editing.
Happening in 8.5.1, while editing - very annoying, but produced vid is fine. Challenge is I can't edit due to the frequency of the stuttering.
Would love to get some feedback on why this happens. I've built a high spec'd machine to record with and still get this issue from time to time however much less frequently than with the Dell Optiplex 790 (i5-2500 @ 3.3GHz with 8GB).
Would love to know if the recording stream or the file playback in the editor are being interupted by other processes that are running on the computer or if there is an issue with the metadata for the file and the way it plays back in the editor etc etc

There is no cure for Camtasia studders. I cannot get Camtasia to play through edits in my latest project. It will export, but the studdering makes editing impossible.

I have the opposite problem. I have no studders in the project but get 2 or 3 per 10 mins of finsihed product.

a best practice with heavily edited projects is to break them into sections, use the Library, and work on just 1 segment at a time
use this portal to access appropriate tutorials ...

Thanks for the advice.
I'm now getting this issue again after setting up on a new kick-ass computer and having not seen it for almost a year. Haven't updated software and it is using different hardware.
The only variable which I haven't ruled out (I am 99% sure) is the software and maybe our business computer image.

kayakman, Champion
not sure what you mean by "business computer image"?
are you using CS 8.6.0. which is latest version?

Not using the latest version. It is 8.4.
Business image is the standard computer image which is put on every computer which the organization (a large university) purchases.
I've seen this issue now with every version of the software that I've tried. I've stuck with 8.4 up until now as it was the first version where I didn't have the issue at all.
I might test with the current version and see how that goes.

I don't think you said what type of source clips you're using?
any chance that some might have variable bit-rate audio?

Ah yes. All recorded using the PPT add-in - 30fps - no other audio or video setting available so you'll know what this should record at - no computer audio -
kayakman, Champion
I don't use the PPT add-in, so I'm just guessing here ...
are the recorded files trec type?
if so, have you tried extracting their contents [right click option from within the clip bin]?
any chance you had Recorder set to not capture audio? I've made that mistake before?

I'm working with a small 15 min audio clip. Before I import, no stutters, after i import several. VERY frustrating.
Worked for several hours today editing with no problems and suddenly it was back again. Audio stuttering so badly that I could not possibly do any reasonable editing. Rebooted the machine, disabled other programs and processes and yet it continued. Downloaded and installed the newest 8.6 version and still the same results.
Running W7 on a macbook pro i7 with 8 Gb ram. Very odd that I had no issues working on similar projects for hours before this started again but now it is so bad I can't do my work. This is certainly not the first time as I've seen it with the past few versions of the program. Any suggestions are appreciated!

Just wanted to add that I am having the same problem and I am on v8.5.2 (build 1999). I have run into stuttering problems in audio while editing for years in Camtasia (although the final production is fine). Usually, it happens when I've done quite a few edits, and the more edits I do the worse it gets. Sometimes Camtasia crashes unexpectedly if I'm doing a lot of edits, which is why I save after every single edit. But in 8.5.2 the problem is REALLY bad. It's taking me a long time to edit because I'm doing a lot of audio edits and it's difficult to actually hear an accurate rendition of the audio when I check my cuts. VERY VERY FRUSTRATING.
kayakman, Champion
what you are experiencing is not unusual; lots of audio edits [timeline cuts] will cause the camproj file to become increasingly more complex, eventually straining the editor
suggestion ...
starting with the original clip [a Camtasia Studio recording?], immediately accomplish any cursor property edits you will want, they will get burned into the AVI in the next step
make some audio edits
when stuttering gets too much, custom produce the project at that point to AVI [capture, editing, and production dimensions should be the same]
start a new project with the new AVI and continue your audio editing
repeat interim AVI productions as needed
when all audio edits are finished. with a final AVI production project, start editing with objects such as callouts, markers, captions, etc
making the interim AVIs will keep editor performance crisp and fast
also, suggest you upgrade to latest CS8 version [8.6.0?]

where did the MP4s come from? what are the clip dimensions; clip durations? do the clips stutter when initially put on timeline, before any edits, or after edits like adding splits or making cuts?
MP4s are from a Panasonic FZ300 recorded in 1920x1080 5 minutes long. Stutters when put into timeline then playing in timeline before or after edits. Processing the video gives a fine video after, but its ridiculous to work with the stuttering deal. It is like Camtasia software does not know how to effectively work with the memory or something. There is plenty of ram to buffer the file I would imagine, but Camtasia can't deal with it.
kayakman, Champion
I don't know what a Panasonic FZ300 is, but it is possible that something about those specific MP4s have a conflict with Camtasia [variable frame rate ??? or something]
maybe try using something like [free] Handbreak to convert those MP4 to a regular MP4?
otherwise, might be best to contact tech support ...

It's a camera, but those are standard mp4 files. Camtasia does the same with videos I take on a Galaxy with Android system.
kayakman, Champion
I understand; but I cannot reproduce the issue with MP4s that have been produced by CS; and I don't have any 3rd party clips
The trouble was still happening, but it appears this step fixed it. Select your audio track. From the menu, select Share, then Export Audio Only. Delete the stuttering track and replace with the exported track. Yeah!!!
I've also just found another solution that worked for me. Right click the track number where your audio is and choose 'Remove track', then click undo to restore the track. The stutter was gone when I did this. It might be an idea to Export the audio though as Roberta says above before you do this in case something happens and you can't 'undo' the remove track option!
kayakman, Champion
this is a very interesting workaround
if you can reliably reproduce the outcome, perhaps contact free tech support and report it formally
