Screen Region Monitoring

Occasionally, I try to capture screen regions when changes occur. For example, during a PowerPoint presentation, a slide might have some builds, and I want to capture each build, as well as each slide change as a picture or a frame.

Similarly, if I want to capture navigation on a web page or application, It would be nice to set a region, monitor for change (e.g. xx%) and capture an image of the region when the threshold is reached. This would be better than actually capturing a complete video. In SnagIt, I could use the individual images, annotate etc for documentation. In Camtasia, I could extend the image (frame) to match any narration I want to add.

It would also be nice to have a feature to capture just mouse movement on top of a Camtasia portion of a video to add a smooth cursor effect matching the narration on top of the static frames.

First, I noticed you're new to these forums. Its best if you separate Snagit and Camtasia questions. Experts want to focus strictly on their area of expertise and are easily confused when you ask questions on multiply applications. I'm not an expert in either, so I'm allowed to comment on both with reckless abandon. Also, include which version(s) of Snagit or Camtasia you're using.

Snagit can capture multiple screens, a whole screen or a user define region. Play a Youtube video and try to capture a region of the video. What happens? As soon as you click the mouse once, the video freezes and waits for you to define a region with a second click and it delivers a single snapshot.
It does not have an ability to capture and compare frames, nor should it. That said, if you google "photo analysis software", there are quite a few even free software tools that you may find interesting. 

Not sure exactly what your Camtasia question is, but if you record a blank screen, say for 10 seconds, and move the cursor hither and yon, then edit the video using as many cursor effects you care to. Try all of them, and if you can't find what you want to do, at least you'll be aware of what Camtasia can do.

Both products are latest version and actually used together to finally create a video in Camtasia.

Solution for SnagIt capture of regions could be to create a capture region and assign a hotkey which I would press whenever I need a new capture.

As far as I can find, you cannot add a cursor to a captured image stretched on a timeline, nor can you replace a cursor from a captured video. The issue is that one might capture a process which may have lots of wait time, and may have to change cursor position after the capture. If I remove the wait times (ripple delete), then cursor keeps jumping around unless I was very careful to avoid movement. I would rather ignore the cursor that was captured, and record a new cursor position as I playback my video. That is not an option which is available. I do not want to highlight any existing cursor movement. Voice narration is added after the video capture, therefore ripple delete is used in many location of the captured video to reduce length and time the cursor movement or clicks with the new voice.

Thanks for your suggestions

regarding cursor disconnects ...

this is one way to solve that issue; this tutorial was made with Camtasia 8 but the general approach can be used in Camtasia 2018

Thanks - interesting, but lots of work when there are lots of pauses in a video. Plus, the fact that the cursor was in a lower position in the example, might have been an incorrect position, and sending the cursor down to bring it back up is not ideal. The idea again, would be to remove the captured cursors, and record a new cursor only as I play back the new modified video.

have you considered removing the original cursor [opacity = 0%], modifying the video; produce; then play the modified video while you capture [again] using Recorder, moving the mouse as appropriate?

Again, a very interesting idea, but that would prevent making any modifications to the original video. Would have to be redone each time. Cursors may not be required throughout the video, only when actual screen captures are necessary.

Perhaps using a combination of the suggestions, I could capture a cursor image with transparent background, and then add that with movement on a different track. But this would not look like natural movement (speed, straight line...)
