I'm using the Lightroom CC on Mac (El Capitan) and the presets downloaded from LRB Timelapse Presets/Templates - lrbplugins.com to create a time-lapse from 180 photo's. All seems to work ok except that the last 5-10 photo's are missing from the video. If I just do an export of those missing photos it works fine. It also includes them when I work back by including others, chunk by chunk, but only to a certain point. Very frustrating!
I've reset my preferences as was suggested in another thread on there, but still the same issues...any other ideas?
Please refer the below discussion and try out the suggestions.
Also, you may create a new catalog and add the images to it and try it.
