Slide Show Effects for Photos – Motion Timing

Summary – Modern slide shows typically contain multiple image layers. These layers are programmed to move in order to provide the illusion of motion. Timing the moves is “the trick”.

.

Figure 1 shows the 4 layers used in this short show

Higher layers in a stack hide whatever is below them

Unless the layer is a mask with transparent areas

The top three images are masks

Masks hide anything behind their opaque areas

Here, the car hides/reveals the city as it rolls along

Figure 2 show the timing steps for the show

The time steps occur at the same time for all four layers, but needn’t

#1 & #4 are the times for the start and end of the show

#2 & #3 are times I added to

Momentarily stop & restart the motion

Figure 3 is a more informative view of the timing & motion

If you scan down the center column

You’ll see where each layer is located as time progresses

The motion between time-steps is smooth & continuous

The car starts far left, ends far right, stops briefly en route

Look at the skyline

I moved if from right to left as the car moves

That’s what happens in real-life

Here is the resulting video

NOTE – it is shown twice

1st – the developer’s view, per Figure 3

To test & confirm the motion is as planned

2nd – the audience’s view, i.e. the final video

Making an abstract? Learning to isolate is important.
