How to get smooth time lapse: Use track from Dynamic Perception.

To record time-lapse scenes of a recent Aurora, Terje Sorgjerd traveled to and around Kirkenes and Pas National Park in Norway - bordering Russia [70 degree north and 30 degrees east.]



Temperatures were around -25 Celsius.


His mission is to record moving time-lapse sequences with still images captured on a full frame DSLR and  3 lenses: - two wide zooms, and one 24mm f1.4 prime.




The Aurora from Terje Sorgjerd on Vimeo.


Here's his camera & Lens kit for his shoot:


  • Canon 5D Mark II
  • Canon 24mm/1.4
  • Canon 16-35mm/2.8
  • Sigma 12-24mm


His all-in-one motion control dolly is from Dynamic Perception


There's a 814ms delay between the shots, with exposure times that range  from 1 second to 2 seconds.


For power in the cold temperature, he chose a 12v 9800mAh CCTV battery that he gets 50+ hours of juice for the track's motor. His coffee thermos runs out before the battery does.

Converted the raw files to 16-bit TIFF in lightroom. 
Rendered the TIFF files in AE to 4k resolution 95% Jpeg.
Edited the 4K video in Final Cut
Exported to 1080P h.264 using Compressor. 
Uploaded to Vimeo.

The 4K version looks better. :-)























  • He was out in the cold shooting sunset to sunrise - all night,  warmed by hot coffee, and moving around to increase body temp.

    Very nice! Thanks for sharing. But what did you use for battery power in such low temperatures? How long was your longest sequence?
  • Terje Sorgjerd plus 1 day ago
    12v 9800mAh CCTV battery will power my two motors and camera for 50+ hours. Problem is my coffee thermos running out. ;-)

Thank you!

Most of the days I started shooting before sunset, and did not finish until after sunrise. I do not mind -25C, but I mind the wind. A lot of hot coffees, and constantly moving around help keep the warmth.

To set the look of each sequence, the images were graded in Lightroom, then batch processed, followed by export.

I use Lightroom for grading.

    So you grade every frame separately?!
  • Nino Leitner plus 1 day ago
    No - batch processing. Grade one and copy the grade to the other frames, then export.






He exported at 30 frames per second.

    stunning work - the motion appeared very fluid , what FPS did you compile / export at ??

    great stuff
  • Terje Sorgjerd plus 3 days ago
    Hey Sebastian,

    This is at 30 frames per seconds.
