Polygon highlight

  • Problem
  • Updated 2 years ago
While making instructional videos, we are trying to highlight various items on the walls for emphasis. Currently, Camtasia Studio 8 only has a rectangle for highlighting. I would like to be able to trace the object in the video so that the whole object is highlighted and not just a rectangle that does not cover it, making it look very 2D and unprofessional.

Can you show a video of what you're trying to do?

as kurrykid requested, a video would be very helpful

but based on some assumptions I've made re your intentions, perhaps this tutorial might be helpful

it describes a technique for creating free-hand-style spotlight effects ...

FYI, this technique can be applied to any spotlight shape desired [circle, triangle octagon, etc]

Hey Bob, loved the video and the technique. I'm curious, however, about the technique you demonstrated and why you took the path you did.

I note that you first saved the frame from Camtasia. Then you resized it using Snagit so it was substantially smaller.

Can you expound on exactly why you elected to resize it before creating the cutout? Why not leave it at that desired size, make the odd cutout as you did, then add it to Camtasia? Wouldn't that have just made it perfectly fit without having to make it larger after you added it?

Cheers... Rick :)

Rick, if you have time, revisit that post and watch again

I remade the tutorial this AM, addressing the issue you bring up

when I first made the tutorial, it was a "shot-from-the-hip" quickie

after original post, I realized I could accomplish the task with better technique, and with fewer steps

I should have used original frame size mask on an enlarged Snagit canvas; that's now demonstrated in new version of tutorial

Trying to upload an example video but YouTube not cooperating. Basically it revolves around perspective. The videos we are producing are for explaining the scope of work to our trades folks. We are trying to show them what, inside the room, is being removed, replaced, or needs attention. For example, there is a picture on the wall, I want to highlight that picture to tell them it needs to be removed. The picture is not directly in front of the camera, it is on the wall to the left, so, due to perspective, that picture is not a rectangle, its a polygon. If I try to throw a highlight rectangle over it, it leaves triangles at the top and bottom that aren't covered or that are covering more than the picture itself. Will keep trying to upload video but hopefully this helps explain it a little better.

did you try the method described in my tutorial?  it will let you create any style custom polygon spotlight effect

alternatively, you could also just use a circle/ellipse sketch motion

re YouTube, have you tried produce/share to Screencast.com?

I did go through your tutorial but that is a little more work than we have time to do. Also, we are looking to highlight multiple items more so than spotlight. They need to be able to see all the highlighted items in respect to the room as well.
Pretty sure my YouTube issue is the firewall here at the office. We are under pretty strict rules and regs as to what we can and cannot do on the internet here. Thanks though!!!

you could also cover the multiple items [separately] with white or highlight callouts; angle them with visual properties, and set opacity to near 0 to give a crude spotlight/highlight effect?

considering you desire to save labor, here's how I'd do it ...

While the screencast you suggested does provide some insight, it doesn't quite seem to cover all of my issues. I was not able to duplicate what he had done using visual properties and the Z axis however. At the end of the video, you will see that I highlight the phone speaker on the table. That required something close to a pentagonal shape. Most of my shapes are going to be like that.

I would like to expand on this discussion.

Are you trying to highlight objects that are contained in a still image without any movement?

Or is this a dynamic and changing scene in which the objects are not stationary or change in scale? 

If the image is still and unchanging.The easiest way would be to create a mask in a program like Photoshop first. You could create complex shapes that cannot be created by rotating a callout. I appreciate where kayakman is coming from but I believe I understand what you are trying to do and why callouts aren't working out.

It  would only require exporting the frame and manipulating it in Photoshop.
Once the mask is created you can control it's Opacity in Camtasia. You could even fade the mask in and out for a more fluid look.

Regards,Joe

thanks for the video

just curious, but why can't you use the tool used in the video?

Do you have SnagIt? It doesn't support layers but I believe there is a way to trick it into doing what I have in mind.
What program are you using in the video? Maybe I can trick it into doing the same thing instead, maybe not. I don't recognize it at all.

I have some free time today and will give it a whirl if you have SnagIt.

Those highlights become permanent. I cannot have them fade in and out as we move about the room explaining the work.

We do have snagit. My issue is I have to keep this as simple as possible as we would like to roll this method out to the engineers and designers on the floor for general use. The program being used in the video is ReCap. It is a point cloud registration and manipulation tool. We are using that software to walk through the space, using the screen capture tool in Camtasia to record the video and audio. Various objects get highlighted as they go, some may get highlighted more than once for different reasons. These highlights are always faded in and out for though emphasis.

Unfortunately, keeping it simple is not so simple. Camtasia doesn't have built in tools for this and I'm not seeing a way to use SnagIt for this.
Will your company let you install the free photo editing tool GIMP?http://www.gimp.org/

I can show you how to create a mask using GIMP. It would require exporting a frame from Camtasia. Opening that image in GIMP. Adding a transparent layer over the top of the image"It's very Easy to do". Then making selections and filling them with color. Yellow is a good color. Then you would save the transparent layer as a png.
You would bring that into Camtasia and place it over the video and adjust opacity, apply fades if you wanted. You could even change the color somewhat by using the colorize feature in Camtasia if need be.

This process is not that complicated but it does require a number of steps.It can actually be done fairly quickly but there is a learning curve initially.

Any way you slice it you would need a photo editing program that supports working in layers to create an effect matching the one in your video.

I can create a video using GIMP if that would help you.

Paul,
I should have thought of this earlier today but now is better then never is it not?

You could highlight using the Polygonal tool over an exported image in SnagIt and fade the entire image in and out over the video as needed.
You can use any color you want and adjust the opacity of the polygons fill.


 You could even highlight the objects with just a border and no fill if you wanted to.



You could even copy and paste the polygonal objects over a "New Image" with a transparent background.
However, this would require a few more steps and SnagIt doesn't copy and paste to the same location.
Meaning you would need to line them back up manually. So it's less than ideal but it is do-able.

Regards,Joe

Like Joe implied, there is no single-click way to do what you want

I did this quick and dirty example using Camtasia Recorder's built-in ScreenDraw tool; it is a fast, easy way to mark up stuff; over the years, I've used it a lot and it has served me well

might be worth giving it a try?

+1 for adding a polygonal highlight to the program's features!

I've been able to work around it for simple highlights in a different way, by simply creating Shapes, with a brighter color and some transparency, all within Camtasia, which is much easier than the frame grab method described here, depending on exactly how you want it to look.
