The images were taken on a Pixel 4 XL. The time-lapses were taken at 5x speed while I was walking. The Web Stories editor doesn’t yet have video transcoding integrated, so I scaled down the videos and compressed them further via
ffmpeg -i input.mp4 -vf scale=-1:1280 -vcodec libx264 -crf 24 output.mp4
This reduced a 5-second video from 15MB down to 2MB (with scaling down from at 1080×1920 to 720 × 1280).
I’m planning to publish another story soon that documents the wildfire smoke in Portland from the horrific 2020 Oregon wildfires. Happily, as can be seen in my story, the smoke has cleared out and beautiful blue skies and clean air have returned.
