I have the LRTimelapse 4.7.1 professional license and I'm no longer able to render a video for longer than 15 seconds.
There are 873 shots in the folder, but when I render the video it gets cut to 15 seconds maximum. Not sure how to fix this.

Hi Mike, please check if this faq post helps you to fix your problem:

If not, please send me the log file after the render aborts (info-menu/show log)

Got it! Thanks! Yeah that was the problem, two cameras with slightly different megapixel counts were used and I batched them together.  I just used the tiff files to throw in AE which always works out well.  My bad, can delete this if you want. Appreciate it!
