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
Hit send one sentence too soon. I also meant to point out that in web apps,
the user could be working with local media files rather than something over
the web — especially if they’re doing A/V production work.

Yeah, I know that lossless is huge, but was curious if there were any
options since it will be a question that gets asked, and therefore I want
to be prepared. My experiements suggest that even where there are codecs
that have a lossless or near-lossless feature in the spec, they tend not to

Lossless video coding isn't really a thing on the internet. There are
lossless modes in some encoders (x264 has one that I'm aware of), but they
tend to inflate inputs rather than compress them. There are systems used
in video production that maintain all the source bits, but they use insane
I’m working on my video codec documentation and have come across the point
where I need to offer suggestions to developers who need to work with
lossless video in a web app, for things like archival and video production
work?
As far as I can see, there aren’t at this time any dedicated lossless
