In high definition you can actually see some of the issues Nintendo had with these pre-rendered cutscenes. For example, Kamek's robe is clipping into his face, objects in the distance suddenly unload, the spikes on Bowser's tail are missing... you can probably spot many more. It sorta feels like Nintendo rushed these cutscenes near the end of development.

The black flash at 08:48 is actually part of EpilogueA. Its not seen ingame because the video gets overlayed by a white layout near the end.

Fun fact: The game's code also refers to a video file named EpilogueB, which doesn't exist in the final release.
