Hello All,
I'm considering buying professional video software to evaluate and
analyze FFmpeg trims and splices and for troubleshooting. My objective
is to improve my edits, and to improve FFmpeg. I'm retired, I have
plenty of time, I have plenty of money.
From here:

"I-frames are also known as key frames because their content is
independent of any other frames and they can be used as a reference
for other frames."
If "key frame" is simply another name for an I-frame, why are there
two names? pdr0 & Balling at trac.ffmpeg.org hint that key frames are
specific I-frames with specific methods but they don't elaborate and I
don't want to burden them.
I'd appreciate an explanation of 'key frame', or a link to an existing
explanation of course. All I can find is keyframe animation, which of
course is a technique, not an MPEG method.
Thank you,
Mark.
Thanks, Gloster. Now I'm going to eliminate everything that has nothing to do
with key frame.

Oh, look at that. There's nothing left. Hahaha.... I just love ffmpeg-user.
There's a laugh a minute.
