Unexplained Luminance Spikes on Keyframes (not where camera values change)

Offline
#1 Jacksoni
I've been using LRTimelapse for a while and thank you for the great software. This is the first issue I'm really having trouble with and can't resolve myself...

Having gone through the whole Holy Grail process as described in the instructions, there are large spikes in the purple 'Visual Lum' column. These are on each keyframe and DO NOT correspond to camera settings changes (holy grail in/out points).

Please see screenshot, it should explain clearly.

I have also tried resetting the whites, black, clarity, and dehaze but to no avail.

As I scrub through the shots one by one, when I pass a keyframe it looks noticeably brighter. However the Exposure numbers are correct.. just the luminance values are off.

Any suggestions?

Many thanks

It seems to be on the keyframes only. Please try again, start with Metadata/Initialize, remove the sequence from Lightroom. Start over the whole workflow.
Mostly this happens, when you remove or add gradients or use unsupported tools in LR. Don't do that. Use only the provided graduated filters. check out this thread: http://forum.lrtimelapse.com/Thread-what...htroom-acr

Thanks for your reply. I've just tried what you suggested and the problem still persists. I applied less changes this time but there are still huge spikes on the keyframes. Do you have any other suggestions?

I'm having the same issue, at key frames. Was there a solution?

It is very frustrating as it takes so long to visual preview to see your efforts go to waste. Is there a proxy way? 

Thanks,

I think I got it, it's from copying and pasting in Lightroom as opposed to not using scripts to paste setting through key frames. Either that, or deleting one of the radial or gradient filter options you give us.
Thanks

Thanks for the update Red sock. I'll give that a try. If that doesn't work I'll send files over to gwegner
