All stills write slowly. The jpgs are really compressed and I want to be sure I get the dynamic range I want, also with Lightroom there is a lens distortion correction. So I shoot DNG only not DNG and jpg that takes even longer. The lens has a moustache type distortion that will show up when you shoot straight horizons. The time lapse would be fun, but only every 10 seconds now, I wish we could do more. That is 6 per minute and if you get 18 min flights that is only 4.5 seconds of video at 24fps not a lot. I wish it would write faster and then be able to set 2 or 5 seconds between exposures. There is some drift but not a lot. I need to try the timelapse but I wish I could a lot more, I can see a fleet of P3 all sequenced....

P.S. If you have After Effects you can use that for generating the timelapse and work directly from the DNGs. AE has masking etc. if you are not on the CC (credit card) bandwagon.
