A clear sunny day, sunrise catches the irrigation wheel lines doing their work in the fields on the valley floor.  Horses and cattle move back and forth looking for the best blades of new grass in their pastures, the new neighbor across the road continues his progress on his place.  Visits by some of the pronghorn antelope break up the day.  Not much 'sky action' to add to events at ground level! 

I've edited the timelapse in Windows Live Movie Maker, shortening some of the long sections of bright sun and blue sky, and slowing down the sections with pronghorn antelope crossing the property.

Timelapse created using an inexpensive USB Webcam pointing out at the world from inside our home towards the North/Northeast. Connected to an older laptop running OBS Studio and ffmpeg freeware to record and process the video.  

To get the timelapse effect I researched how to set parameters in OBS Studio to record at 1/6th of a frame per second. This captures a frame of video every 6 seconds. Unless the recording is modified, that frame will also take up 6 seconds of the playback from the raw recording, sort of like a slide show.  

To make this into a usable timelapse, I have to remove that extra length of each frame. So I processed the video using ffmpeg, another open source tool, to shorten those frames and get the video to have the timelapse effect.

I've added some overlays to the OBS Studio recording. One to indicate day and time, and the other to display a portion of my home weather station data.
