Larry,
Those are very nice and interesting videos!
I've been uploading videos made with both K-5s and most recently K-1 to
Youtube. Here are a few thoughts and hints based on my experience.
I don't know what format K-3 is using. K-5 and K-7 were using video format that
is not well compressed, "Motion JPEG". And the file container was .avi .
To speed up the upload and to conserve my monthly bandwidth allowance, - I was
recoding it to MP4. To give you an example of just one file (~3 min): 882 MB ->
290 MB
K-1 is using a better codec (H.264) to compress the video, so the videos
are smaller to begin with. (And the container is .MOV)
Yet, I sometimes recode it as well.
E.g. 0:54 sec is 148 MB -> 28 MB (This video subject seems to be more
compressible in general, hence a much smaller file per minute.)
(After a quick google search, I see that K-3 is using the same video
format (MPEG-4 AVC/H.264 (MOV).)
To recode, I use a free tool called Avidemux. I am using it on Windows, but I
believe it exists for macOS too.
It also allows cuting videos (and splicing them, - but no fancy effects. For
those, you can try a free tool called VSDC, and Wings
Platinum 5, which has a free version ("Basic", IIRC).
Avidemux also allows replacing (or removing) audio tracks easily.
I use these command line options for Avidemux conversion (to optimize for
Youtube):
avidemux_cli.exe --nogui --load VIDEO.mov --video-codec x264
--audio-codec LavAAC --output-format MP4 --save "VIDEO-upload.mp4" --quit
(I suspect --nogui is no longer needed.)
Sometimes, I recode manually, but sometimes I run a batch file.
Let me know if you want one as an example, and I will send it to you
directly.
HTH,
Igor

Fortunately, the one with the best action was only 39 seconds / 105 MB and only
took about half an hour to upload.
