Photoshop animation experiment worked - stick figure and tweening

I've gotten a lot of ideas for simple animations lately, mostly involving cats, no surprise. I heard many times that the video tools in Photoshop also work for single frames and the "tween" feature fills in between the frames to make them appear animated.

I wanted to be sure at least basic animation could be done with the Photoshop I already own, so I created 4 frames with the brush tool then looked at them in the video timeline. At first I couldn't figure out how to animate them, and fill in frames between their poses. After some pasting and fiddling with features I learned in a video editing tutorial recently, a few seconds worth of animation and tweening appeared.

I'm not sure why the ghost effect appears but I'm pretty sure it can be turned off. I have some other projects on the go that need to be finished so this was the result without too much fuss (maybe an hour's worth of trying different arrangements and tools):

As you can see, Photoshop does indeed allow quick and dirty animation to be done. I'll be a lot happier when I grasp the video and animation tools better. My goal is to add animated line art and possibly whole characters to my video projects. This is why I've been practicing watercolour, pastel, and charcoal drawing, and practicing with my new Wacom tablet. I like the idea of splicing or pasting in different hand-made effects into digital modern video recordings (websites too), to create an engaging story.

I enjoy making art, of course, but animation for websites and videos is the real application I want to excel at, for making modern low-budget but invigorating short promotional videos for non-profit agencies or sports teams, and similar.

As soon as my skill evolves, I'll be sure to share the news and examples here and on my YouTube channel.
