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: https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/uc_system/design/guides/videodg/vidguide/basics.html "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.
Not sure whether this is any help, but it was suggested when I asked for suggestions in another place for you.
