Frequently Asked Questions

Q

What interval should I use for time-lapse?

Clouds: 3-5 seconds. Sunset: 2-5 seconds. Stars: 20-30 seconds. Traffic: 1-3 seconds. Flowers blooming: 1-5 minutes. Construction: 5-30 minutes. Match interval to speed of movement.

  • Fast clouds: 1-3 seconds
  • Normal clouds: 3-5 seconds
  • Sunset/sunrise: 2-5 seconds
  • Star trails: 20-30 seconds
  • Traffic/people: 1-3 seconds
  • Plants/flowers: 1-5 minutes

Flowers2 min8 hours10s (240 frames)
Q

How many frames do I need for a smooth time-lapse?

Minimum 150-200 frames for a watchable 5-7 second clip at 30fps. A 10-second clip needs 300 frames. For a 1-minute sequence: 1800 frames. More frames = smoother and more flexibility in post.

  • 5 seconds: 150 frames (24fps) to 300 (60fps)
  • 10 seconds: 240-600 frames
  • 30 seconds: 720-1800 frames
  • 1 minute: 1440-3600 frames
  • Shoot extra — you can always trim in editing
Q

How much storage do I need?

RAW file sizes: 25-50 MB each (full frame), 15-25 MB (APS-C). JPEG: 5-15 MB. For 500 RAW frames at 40 MB: 20 GB. Always bring double the calculated storage for safety.

  • RAW (full frame): 25-50 MB/frame
  • RAW (APS-C): 15-25 MB/frame
  • JPEG high quality: 5-15 MB/frame
  • 500 RAW frames ≈ 20 GB
  • Bring 2× calculated storage
Q

How long does my camera battery last for time-lapse?

Most mirrorless cameras get 300-500 shots per battery. DSLRs get 800-1200. Cold weather reduces by 30-50%. Use a battery grip or external power for long shoots (1000+ frames).

  • Mirrorless: 300-500 shots/battery
  • DSLR: 800-1200 shots/battery
  • Cold weather: -30 to -50% battery life
  • USB-C power: unlimited (check compatibility)
  • Battery grip: double capacity
