I have optimized my workflow for HDR timelapses and this is the best result I got so far. Since the weather was only "medium", please don't expect a spectacular HDR effect: https://www.youtube.com/watch?v=wp-Vm6UzxVg

These are the timestamps for the photo timelapses:
0:23 - 0:34
0:41 - 0:46
2:44 - 2:53
3:03 - 3:07
3:13 - 3:17
3:51 - 3:55
4:06 - 4:15
4:44 - 4:48

I will explain my workflow soon in a separate thread.

Nice, looking forward to hear about your workflow!
