As you may already know, there are two types of loops you can select for your cinemagraph: bounce and repeat. As the names suggest, a bounce loop will bounce the motion in your cinemagraph forward and backward while a repeat loop will repeat the motion from beginning to end.
Repeat loops are best suited for cinemagraphs featuring motion which travels in a single direction. Some examples of moving subjects that would suit a repeat loop are water, transportation, and smoke.
Repeat loops can often be more difficult to perfect than bounce loops because motion doesn't always repeat identically. Continue reading to learn how to apply crossfade for different types of motion.
The first step of creating a perfect repeat loop is to select a trim up to 10 seconds in length. Match the first and last frame of your trim as best as possible to ensure there is a seamless transition between loops. Next, you can adjust the crossfade to define the type of transition between loops.
Increasing the crossfade will produce a gradual transition between loops. A longer crossfade is best suited for motion which does not repeat identically; it will blend the end and beginning of your trim to create a smoother transition between loops. Below are a few examples of motion which does not repeat identically:
- Pouring a liquid into a glass
- Waves rolling in at the beach
- Steam coming from a hot beverage
Decreasing the crossfade will produce a more sudden transition between loops. A shorter crossfade is best suited for motion which repeats identically. Motion which repeats identically is often rotating on an axis or occurs at timed intervals. Below are a few examples of motion which usually repeats identically:
- A windmill rotating on a windy day
- Rotating wheels on a vehicle, bicycle, or skateboard
- Flashing street lights
