Camtasia:Mac performance with tablet and stylus

  • Updated 6 years ago
I'm using Camtasia:Mac with a Wacom tablet to record inking on the screen. When Camtasia is not recording, the performance is great! But once I start recording, the inking skips and frequently can't keep up with the stylus.

The Quicktime Player screen recording feature (found in Snow Leopard and Lion) doesn't have any lag problem. It can capture at a high frame rate with no skips at all. But QT doesn't have the ability to set the capture area to a precise area (e.g., 1280x720).

Is there something I can do to improve capture performance?

First, make sure you are on the latest version of Camtasia for Mac (2.0 as of this writing, but check the website), which should provide the best performance.
Second, I'd make sure to turn off any type of recording you aren't using, such as system audio, if you're not using it.
Any other programs you are running could be closed to free up resources as well.

We do not normally find that our recording performance gets in the way, but perhaps there is something odd we should look into further that is specific to the Wacom tablet, and has nothing to do with system resources at all...

I suppose, as a work around for now, if none of that works... you could record with the QuickTime Player since you say that works fine, and then use Camtasia to edit it and crop it down, do your splits/annotations/etc. Just set adjust your canvas to be the size you want and move/size the video to be what you desire.

I'm having the same problem with my Wacom Bamboo Create tablet and Sketchbook Pro when writing text on the screen. When Camtasia is not recording, the performance is great! But once I start recording, the inking can't keep up with the stylus.

I tried unplugging the tablet and going to mouse. Again, works well--minimal lag. But writing text with a mouse is simply not an option.

I am running Lion 10.7.3 (latest version), latest version Wacom drivers, and latest version Camtasia (2). I have 8GB RAM, and a dual core Macbook Pro. So its not drivers and not the machine.

But it is annoying as hell--at this point, I'm ready to toss both the Wacom and Camtasia. But I need both for khan-style videos.

Any suggestions would be greatly appreciated.

I ended up using either QuickTime Player or a competitor's product (S**** P** made by A*********). The QuickTime Player sends the computer's fans into overdrive. The other product works quite well -- no lag, no fans.

As Paul said, I can then bring it into Camtasia for editing before uploading to YouTube.

You can skip the ***'s; we do not mind honesty here, though I appreciate what your'e going for there. If there are times when our performance is not up to snuff, or there are conflicts we do not know of with other software, it is better for us to know of it.

Perhaps SnapZ Pro is not using any compression at all when recording, which is generally terrible for long recordings of your screen, but if your Wacom (or Sketchbook) is using up all the CPU (??) there might not be any left over for Camtasia to use to compress the video during recording. This is just a guess, but since QuickTime gets the fans going too it's a reasonable bet. I'll see if we can get ahold of one of these and test out your scenario at some point on a similar machine. Sometimes it's hard to find figure out where the bottleneck is (CPU, GPU, RAM, fairy dust).

If I need an editor, I can use FCPX--which is what I use for my other video work. So I don't need Camtasia for editing. I did try a competitor's screen capture software--iS***U HD, but I had the same problem with lag. So I assumed it was a generic problem. I'll see if I can figure out which product you are referring to with S*** P** (did you put in the **** or the site moderator?).

In any case, thanks for the update. I will try to do the same if I can work this out--or if Camtasia does (which I would find optimal).

I checked your profile. It lead me to Twitter. Ug. Tried following you so that I could send you a DM. OK, so Twitter is not my strong suit. MAybe you do better with it. Search for RebMeilech.

BTW, I did figure out which program you were referring to. Installed it. Now I'm trying to figure out how to capture a movie with it. Might have to read the manual or watch a video.

Hope it works.

Paul,

Fair enough. I downloaded the trial version of SnapProX for Mac and tested it with Sketchbook Pro, Wacom Create--same setup as above. On my laptop monitor I got no lag--on my external monitor (where I have the screen size set to 1280x720) I got a barely discernible (read: acceptable) level of lag.

As far as I can tell, Snapz does its compression after recording--which frankly is not only fine with me, I prefer it. There were a lot more options for compressing. It does not have Camtasia's editing suite. But as I wrote above, I don't need that--I can use FCPX for heavy work, or QTP or iMovie for light work.

In the midst of all this testing, I ran my Activity Monitor. It looks like SKP takes from 35-50% of my CPU (I'm not certain I'm reading this correctly, but that's what it seems).

I've got about 14 days left for both my Camtasia:mac and my Snapz trial. I look forward to hearing your results.

I have the exact same issue with Camtasia for OSX, using a Wacom Bamboo Create tablet and Sketchbook Pro. Writing with the stylus works well when not recording but becomes a little more sluggish and less responsive when recording (this is an iMac with i7 processor and 8Gb of RAM, a good machine). It's still possible to write while recording but I must keep it slow to avoid missing strokes, and this is not ideal for recording video lectures. I'd appreciate a solution as I'm quite happy with how Camtasia is working in all other respects.

My tablet will not move when i start...It's stuck at one pace or moves very slowly and lags a lot...I got a Bamboo pen and touch, don't know if it's only that one that will not work?

I'm having the same issue with a Bamboo Create tablet and Camtasia:Mac 2.5. Oddly enough, it worked fine until recently.
