> As I understand this is some complex relation that is not obvious,
Elecard does not print that any frames depend on those two first B frames,
but clearly they must as shown by mpv. (mpv click . 1 time, that second
frame (4th actual frame) is shown corrupted.)
On the right side? That's not corruption. That's fade-out on a burning
torch. Would you like a longer clip so you can get a better sense of the
material around the splice?
Balling, I'm having difficulty. Would you kindly identify the frame you
call "second frame".

You see? I removed the open Bs and rewrote the I-frame's DTS. I cannot
discern IDR-frames v non-IDR-frames, and apparently neither can FFmpeg or
FFprobe.
