Time-lapse and star trails video

Turn the same photos into a smooth time-lapse, or a video of the trails growing across the sky.

Step 1/4
Start from your selected photos
Pick your night sequence with "Stack Images" as in the previous guide.
On the screen with "What would you like to create?", scroll to the video options.
Step 2/4
Time-Lapse Video
Tap "Time-Lapse Video". Each photo becomes one frame, so you see clouds drift and the sky turn.
30 FPS is smooth; 60 FPS is extra smooth. 720p is free; 1080p and 90 FPS unlock with a short ad.
"Reverse" plays the night backwards, which is great for loops.
At 30 FPS, 300 photos make a 10 second video. Fewer photos make a shorter video.
Step 3/4
Star Trails Video
Tap "Star Trails Video" for the trails drawing themselves across the sky, frame by frame.
Comet Mode lets older trails fade as new ones appear, so the sky seems to flow.
This one takes longer to make, because every frame is its own star trails image. The progress shows each stage.
Step 4/4
Find and share your video
Videos save to the Trailium album like images. The floating progress pill takes you to the result when it is ready, even if you left the app.
