Keyframe Issue - Keyframes too bright/dark after bringing them to LRTimelapse

Offline
#1 adsrabs
Hi all,

I'm fairly new to LR Timelapse and I'm still getting used to the workflow etc. There's one thing I'm trying to get my head wrapped around but nothing seems to be making any sense. I'm trying to process a sunset timelapse and I'm using the holy grail workflow. The issue is, my 6 keyframes in LRT are far too overexposed compared to how I have edited them in Lightroom and I'm trying to figure out why this is.

It was my initial understanding that the keyframes you edit in LR should look exactly as you processed them, and the images around the keyframes are adjusted to suit, but it looks like this is not the case. To try to fix the issue, I tried to lower my offset in the holy grail which made the first half of the sequence darker but oddly enough the second half even brighter than what it was. 

Please see relating images below. Any tips or fixes appreciated. 

Cheers,
Adam

You have most likely not used the sync script to bring the settings from one keyframe to the next, see faq: http://forum.lrtimelapse.com/Thread-how-...ync-script

Hi Gwegner, thanks for your prompt reply.
I have tried your solution and re-done the visual preview but this has not fixed the issue unfortunately.

You have to redo the sequence, otherwise you won't be able to fix it. Start with "Metadata/Initialize" in LRTimelapse. Then redo the workflow.

I have redone the work flow as suggested but unfortunately the sequence is still really over exposed. Keyframes 1 and 6 now seem to be as per the edited photos when compared to the lightroom versions, but keyrames 2 - 5 are far too bright and don't look anything close to the edited lightroom files. All keyframe files have had their metadata saved to file as well as sync script.

Did you add any Gradients or remove the predefined gradients? Or did you use any tools that are not supported by LRTimelapse?
See: http://forum.lrtimelapse.com/Thread-what...htroom-acr
Do you have the latest Adobe DNG Converter installed? Please make sure!

Those could be the only other things I can imagine causing that effect.

Hi Gunther,

I am having problems with this same problem of only the files with the keyframes looking good. the rest are over exposed.

Trying my first Holy Grail time lapse through LRtimelapse. 

I have 1,600 frame sequence. Going from sunset to night to sunrise into day. At first when I was not happy with results of using 20 keyframes I went back and added another 28, total of 48. Is there a limit to the number of keyframes you can or should use?

I did add gradiant filters, using the ones LR Time lapse provided, not ones from light room. When I was finished with the grads, I clicked done. But when need to use the further down the sequence I could not bring them back up.

Thanks,

Tom

Something seems to have been messed up then. I'd suggest to start over from scratch (use metadata/initialize in LRTimelapse) and do the editing again.
Make sure to
A) have installed the latest Dng converter (see install page)
B) be using the sync script in Lightroom
C) not adding or removing gradients

I'd not recommend to use so many keyframes. There is no technical limit, cut normally 5-8 are enough. There might be exceptions however.

Ok, I will give it another try without the grads, but will miss them. 

I do have the latest DNG converter. I have been using the "Sync Script"

I down loaded your E book "Timelapse". That helped me to get a starting point on how to change exposer in camera to help the process latter in LRTimelapse. Normally I use ND filters to keep both my shutter time down low and a f/stop no higher then an 8. Without a filter, where do you set your shutter in full light? 

Thanks again,

Tom

I didn't das to not use gradient filters in Lightroom. I said that you should only use the ones provided by LRTimelapse (4 linear ones and two radial).
And I certainly did not say not to use an nd filter when shooting
