Winter is coming : 1212 hours timelapse (50 days)

Year ago I recorded 50 hour timelapse - now it's time for 50 day timelapse (1212 hours). Starting from green leaves to snow. Shooting on Xiaomi Yi, 1 frame per 30 seconds, and then - 16x faster in ffmpeg via frame averaging. Total video speed is 28'800х realtime. Original video was ~80 minutes, 28.7Gb (50Mbit/sec bitrate).
