Flickering problem - Jose Mario - 2014-07-28
Hi, I shoot thinking that the holy grail manual adjusment need to be done every time the camera light meter changes to compensate the absence of light. Now I have very strange exposure curves with a lot of flickering (like the one of the picture i attach). I already try to use the deflekering process but I still see the flikering. Also I try to use the holly grail sequence in LR Timelapse and then Deflicker the sequence but with bad resultus. Any idea of what I have to do, I have a lot of timelapses with the same exposure curve.

I would use the holy grail workflow, without deflickering. Before doing that go to the settings/expert settings and set the threshold value to "0".
Then initialize, create keyframes and apply the HG-wizard. How does the curve look like then?

¡Thanks! it improve a lot. But I also notice differente exosures in some 2 an 3 stars photos. What process I can use with Adobe Bridge?
RE: Flickering problem - Gunther - 2014-07-29
Either you try to refine the matching by manually adjusting the exposure or you use deflicker on a second step on your intermediary sequence. It's all explained in my EBook, see signature.

Thank you very much Gunter!
I did get to to have like a 98% of flickering. In a 420 sequence I only not get to match 4 frames. But I use the worflow of the page 100 of your book and it works excellent for me. Those frames that I can't match looks different from and exposure match. What I want to say is that I Can't find a match (manually) for those frames. Do you have any suggestion?
Thank you very much again and sorry for the bad english.

Hi Jose, if you can't match them manually the algorithm probably won't as well.
Most of the times one of the 2 frames is then over exposed (clipped channel). There is not that much you can do, check out this thread for some suggestions.

One last question Gunter.
I have a sequence where I have 2 and 3 star photos in the same row (you can see it in the attachment). What's the best thing to do here? I do the process that you mention in your book to start with from left to right in the 2 and 3 stars sequences. I still get to have a little jump in the file 136 and 137 that are different.

Why don't you use the Keyframes Wizard? It should be able to handle adjacent 2* keyframes well.
