We had some decent overnight rain, but despite that it was smoky again today. Clouds still make their appearances above the smoke and through the haze, and put on quite a show in the mid-afternoon. 
The weatherunderground site, which I use as a source for pulling in the temperature and wind data to the OBS scene, kept going offline today - apparently they are having a few issues. Hopefully they'll get it straightened out tomorrow, if not I will try to use the Ambient Weather dashboard to source the data.

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.
