Beautiful! 🥰 Liked 👍🏻 Subscribed ⭐
I'm still working on my timelapses from that day, but I've got a lot of flicker in the shots (still don't know why - I captured northern lights in Norway few times without any problems).
Many greetings from Zürich! ✨🙋🏻‍♂

Shoot in RAW format, aperture fully open and don’t apply afterwards too much nonlinear or content aware enhancements like contrast highlights, shadows, details, dehaze. These work differently on each frame separately and give different results. I just raised exposure, because I did not know how bright they get. Flickering from aperture (diaphragma is not 100% accurate) can be fixed with LRTimelapse. Any further editing for enhancement must be done on final video to get it smooth across all frames.

@@bnies73 Thanks a lot for the great hints! When I exported unedited imagery, with no adjustments, there was no flicker 😀
I shot fully open aperture (F2.8) and previously never had this problem. Deflicker in LRTimelapse was not able to deal with it even when I was setting the custom region for the deflicker area... I really appreciate your help! ✨👍🏻
I will check which of the adjustments created this problem and try to avoid it in the future. I also exported it as 16 bit TIFF files and merged it into Pro-Res video, so I can likely get similar results in color grading in Final Cut Pro.
I will keep you posted - but your advice unblocked me 🥰

@JaroslavBengl It's mostly contrast/highlights/shadows. Use tone curves in Lightroom instead to achieve similar result. th-cam.com/video/xb6UZsUEpSI/w-d-xo.htmlsi=1jnqi3mOKrYC5NVi
