I'm working on a very straight forward time lapse sequence with 751 images in DNG format loaded via Lightroom. The initial preview had minor variations in Lum values until about 75% through the sequence. Then there was a brief peak followed by a dip and then back to about the same level as the first half. The peak and valley aren't wild swings though.
Using the wizard I created 5 key frames. There were a few, perhaps 10-15, ISO changes I made during recording. So I used the Holy Grail wizard to smooth that and then saved the meta data. I used very minor slider adjustments with the Holy Grail sliders.
In Lightroom I adjusted the key frames and used the script to copy forward the changes progressively. I did use both of the radial filters and one of the gradient filters. I did not make any changes in crop. Visually in Lightroom, the exposures were relatively close. Certainly no wild shifts.
When I used Reload in LRTimeLapse, there was a gap of about 10-12 frames where the Lum values were actually lower than the initial Preview Lum values. Although all my adjustments in Lightroom were to brighten all five key frames to various degrees. When first loaded, the initial preview frames were all brighter than what you would see in Lightroom with zero adjustments, I assume this is an "auto" JPEG conversion thing. For the frames which make up the gap, it appears as if they reflect the exposure level of the raw file with no "auto" JPEG adjustment. Much darker than before the Reload.
The gap occurred a dozen more more frames past the first key frame, and well before the second key frame. I've tried several different things to "fill the gap", but each time the gap simply moves - appearing earlier or later in the sequence. The number of frames in the gap also varies as different attempts were made. I tried:
- simply re-execute the Reload
- resetting the meta data
- clearing the meta data
- reloading the exif data
- removing the .lrt folder and all the xmp files
Any thoughts on this? I saw in another post someone had some what similar issues with Visual Previews and it seemed the deflicker step either corrected or mitigated the issue. Although I've not tried moving on to that step.
Thanks!
