Here’s a Step-by-Step Guide:
Step 1: Open Adobe After Effects. Go to the composition and create a new composition. Rename it to Twinkling Stars or whatever name you give it. Set the resolution to 1920×1080 Pixels. Set the frame rate to 30 frames per second, and the duration to 20 seconds.
Step 2: Go to the Layers Menu > New > Select a solid layer, then rename it to the background.
Step 3: Go to Effects and Presets. Search the effect gradient ramp. Then drag and drop the gradient ramp effect to the Solid layer. Change the second color to dark blue. Leave the First color to black and the Second color dark blue (#26007C).
Step 4: Create a new solid layer then rename it to Stars or whatever name you like. Go to the Effects and presets. Search the effect of CC Particle world. Drag and drop to the screen.
Here are the CC Particle World Settings:
Birth rate to 3. Set Longevity to 5.
Physics: Set gravity to 0.
