Hi,

I'm running into trouble with a timelapse I recorded with automatic exposure time and manual changes in aperture from time to time. I'm following the workflow shown in the tutorial but still have a lot of flicker, especially in the sky. When I run visual deflicker (selected the sky before) deflicker values are calculated, however the pink curve is still far from beeing smooth

I tried to increase the value of visual deflicker, that smoothened the pink curve overall, but the small kinks remained unchanged.

Any ideas what I'm doing wrong?

cheers

Do you have the latest DNG Converter installed?
Please check this and install the latest version. Make sure that the Thick Green curve is not too far away from the pink curve, it should only smoothen the flicker out. Make sure too to not use too strong edits for the keyframes, see: http://lrtimelapse.com/news/use-the-new-...me-lapses/

I've DNG convert 9.1 installed and did only little changes in exposure, shadows and a constant clarity of 20. Any other ideas?

Try removing the clarity from the sequence. You can do so by unticking "hide unchanged properties" in LRTimelapse, then on the clarity column head, right click and "initialize". Then set a reference area to the sky (click and drag into the preview).
Now save and let the visual previews build. When done apply visual deflicker, save and wait for the VP to be rebuild. If they are still not smoot, click on "visual deflicker" again and refine the deflicker. You can do so until the curve is rather smooth.

I followed the steps you described, however with virtually no improvement. The red curve gets more and higher peaks, however the pink curve looks almost the same and I have still a lot of flicker in the video.

Funny thing is, when I used 400 samples with the free trial of LRTimelapse in the middle of the timelapse it worked out quite good, may be not perfect. But it was my first try.

Any ideas? My last idea is to delete all xmp's and start from the beginning...

Yes, try doing that. Delete the hidden ".lrt" folder inside the timelapse sequence too to discard the current previews.
BTW: Make sure to always have the latest Adobe DNG converter installed!

Deleting the xmp files, the .lrt folder and start ffrom scratch seems to be the solution. The timelapse preview is now half way through and the pink curve looks pretty nice as does the preview. Are some known things in that workflow that should not be repeated otherwise the xmp files are screwed up? E.g. after having the timelapse deflickered a first time can I go back to the keyframes, change them in lightroom, safe metadata of the keyframes, load again in LRTimlapse and so on?

Thanks for you quick support!
