That’s really good advice and I’ll tweak my content around that. Thanks to
both of you for your input. I still personally feel like there’s room for
using device-local uncompressed media in a media editing context, but I
suppose that’s a pretty incredibly niche market. :)

Regarding "near lossless," the best option I've seen is using x264 with
"-crf 18 -preset ultrafast", which is basically a very high quality copy of
the video with a high bitrate due to the "ultrafast" preset.  There's
minimal loss of fidelity, but it's also still relatively quick to do the
encode because x264 is exceptionally performant.

I use this extensively in a video processing pipeline I wrote (2
million-ish videos a month, at the moment).  It's a total lifesaver,
because processing video in a lossless way requires such a huge amount of
storage/memory that it's almost not worth consideration for anything but
digital mastering of original content. A better approach in probably ~95%
of situations is a "near lossless" approach.
