Jeff Geerling ☛ Highly-condensed time-lapse footage with Frigate
Once I've exported the file, it's available to download from the server where Frigate's running (or a network storage location if you have Frigate configured to record to a network share). I download the file, then run the following ffmpeg command to re-compress it and speed it up a bit more (4x faster) than Frigate's own export functionality does:
ffmpeg -i exported-timelapse.mp4 -vf "scale=1920:1080,setpts=0.25*PTS" scaled.mp4
This also downsamples the footage to 1080p (from the original 4K source).

The New Leaf Journal ☛ Organizing RSS and ATOM Feed Sources
I use The New Leaf Journal to advocate for using feed readers to follow [Internet] writing and media using RSS, ATOM, and JSON feeds (see our feeds). While the big tech social media platforms such as Facebook (feeds are a good alternative to getting news from Facebook) and X (and X) have an incentive to keep readers on their platforms, feeds provide a way for individuals to follow what they are interested in without a middle-algo. I shifted to using feeds in conjunction with a read-it-later set-up for my own reading after a hiatus following the Google News era. One challenge I had concerned how to organize my feed collection in my feed reader.
