Download Parler videos after the takedown, like this:

https://parlervid.herokuapp.com/VIDEOID

Where VIDEOID is the id of the video you want.

Goes great with this map.

I also have some mirror-processing tools in here. I started getting rate-limited at (https://pl.gammaspectra.live)[https://pl.gammaspectra.live/video.parler.com], so I had to download files (the torrent & dupes.txt) and process them locally. It ended up much faster.
