I've tested this several times on different folders, but the keyframes in LRTimelapse don't seem to translate to the star ratings in Lightroom. It only marks the first keyframe with one star. The other keyframes simply don't get rated. I know I can still go back into LRTimelapse and manually check the keyframes (by file name) and then rate them as one-stars in LR, but it's a bit tedious and I'm sure that's not how it's supposed to work anyways. Any ideas?

Please follow the workflow exactly. Make sure that when reading the Metadata in Lightroom, you are in Grid Mode (G) and have selected all images.

Ah yes, rookie move on my part. Thank you.
