I usually use the simple fade transition from one piece of video or picture to another. But I have found that if I leave a small gap between the picture/video elements, I can get an old fashioned slide projector effect of changing slides.
This is a lot of wok when you have dozens of pics to edit.
Why not create a built-in "slide show" transition style.
A slideshow transition sounds good to me. I cast my vote of approval.
However, if it is incorporated as a feature. It could be a long time coming.
I'm thinking by your description This is pretty much what you're looking for.
There is a workaround that could save you a lot of time. It’s a bit clumsy but effective.
What you would do is take a black rectangular callout and center it over the top of two images.Resize the callout until it covers the entire canvas. The duration of the effect/transition would be up to you.
In my image below. The duration of the fades are five
There are four frames of Solid Black/Zero Opacity in between the Fades. So the entire animation is only 14 frames in duration. You can tailor the duration of the fade transitions and black frames to taste.
Once you’re satisfied with the effect. Save it to the library. Then drag it over the top of your images whenever you want to use it.
You will want to zoom into the timeline to apply them. It may not be a piece of cake to center it over the top of the media.
Positioning any solid black frame above the split in the media below. Will allow the transition to work. So placement can be somewhat imprecise and still create the desired effect.
Doing slide transitions in PowerPoint is easy. That's because it is slide based. Duh!!!
That's not to say they can't be accomplished in Camtasia though.
More transitions to chose from would make a big difference and less work of the process.
A common slide transition is the old 35mm slide projector carousel transition.
Here is a example I did in Powerpoint. With the Powerpoint Camtasia add-on it could be recorded and
then more editing done in the Camtasia editor if needed.
The gif's examples are a little fast but that can be easily adjusted to what ever speed you want.
Had to link to the gif. Couldn't upload it to the post. Getting that stupid Bad Gateway error this morning.
Here is a similar example done in Camtasia.
The layout I did was to put a annotation Square Shape in front of each clip. Duration was about 0.12 Once you make one you can just copy and paste to add the rest of them.
Then I dragged and applied the Slide Left Transition to the shape and the start of each clip.
Duration of the transition was about 00.04
I as said, more transitions in Camtasia would be nice to have.
Here is a cool page I found where you can see a preview of different slideshow transitions.
Good to get some ideas for your videos.
Sadly doing them in Camtasia is another story.
The layout makes it so there is nothing to "line up" or having to apply multiple in/out fades.
Put a annotation shape in front of the clip (color of choice) and adjust the duration to taste.
Copy and paste it in front of any other clips.
Then drag and drop the transition onto the shape and the start of the clip.
** You can select all of the annotation shapes or all of the transitions and adjust the duration all at once to find the effect you desire.
As a video it plays back smooth. The gif is a low frame rate to meet the upload size limit on the forum.
It's a pretty straight forward layout.
