Split Screen

A small inset video window plays over the main picture and can be moved or resized.

This is for a motion graphics video. Add a "Picture-in-Picture" (also called PiP or TV in TV) to [scene]: a small inset window plays a second video over the main picture.
Both pictures should keep playing at the same time, and the main one still fills the whole frame behind the window — if the frame is divided into panels that sit side by side, that is a split screen.
Over [duration], bring the window in at a corner, then move or resize it so it stays clear of what matters in the main picture.

Movement advances in visible jerky steps at a low frame rate (e.g. 8-12 per second), imitating frame-by-frame photographed animation.

This is for a motion graphics video. Give [scene] a "Stop Motion Look" (also called stepped animation or the posterize time look).
The movement should advance in visible, jerky steps at a low frame rate, each pose held for a moment as if it were photographed one frame at a time — the picture stays on throughout, unlike a strobe.
Run it over [duration] at its normal pace, keeping the same choppy rhythm from start to finish.

The picture appears as rapid on/off flashes so motion looks frozen into discrete jerky poses (or wheels seem to stand still or spin backwards).

This is for a motion graphics video. Add a "Strobe Effect" (also called a stroboscopic effect) to [scene]: the moving subject shows only in rapid on/off flashes.
Each flash should catch the motion frozen in a separate pose, with nothing of it visible in between — a stop motion look keeps the picture on and only lowers the frame rate.
Run it over [duration], and keep the flashing gentle and confined to the subject so it never turns into a harsh full-screen flicker.

Slow real-world processes (clouds, growth, crowds) appear to run at high speed because frames were captured at long intervals, giving a stepped, flowing look.

This is for a motion graphics video. Show [scene] as a "Time-Lapse" (also called time-lapse photography): the camera stays locked off while slow changes race by.
Light, shadows, clouds or growth should flow quickly with a slightly stepped feel, as if the frames were taken far apart — sped-up continuous action is fast motion, and a camera that travels between frames makes it a hyperlapse.
Compress the whole change into [duration].
