Dark scenes in the last chapter detected as credits

[tannisroot]

I have an issue with some of the episodes of TV Shows where the first scene of the last chapter in an episode is relatively dark, leading to the whole chapter being labeled as credits.
For example, this happens with S03E14 and S03E19 of Stargate Atlantis with intros that are around 250 seconds long, as well as S10E04 of Stargate SG-1, where the credits are 555 seconds long.
To try to mitigate this, I've tried setting "Maximum credits duration (in seconds) " to 120, unchecking "Ignore duration limits for chapters" and then pressing "Erase all credits timestampts" and and running analyze task again.
However, this had no effect (perhaps I'm missing something?).
What could I do to fix this aside from disabling credits detection altogether?

You can try setting the credits analyzer for the series to Chromaprint in Edit Timestamps. This analyzes the audio fingerprint instead of relying on visual cues, which might help in cases where dark scenes are mistakenly detected as credits.

Is there a way to do it globally? There are many episodes in different series in various seasons that have the same issue with really long wrongfully detected credits that for some reason are longer than the maximum limit, and those are just the ones that I've seen, I would hate to go manually through each season of each series in my library to select Chromaprint detection.

You could try using the preview release and enabling Prefer Chromaprint. Alternatively, you could add "Anime" as a tag or genre to the shows, which will also prioritize Chromaprint for credits detection.

Seems to work!

Does it fallback to other methods, like black frame, if chromaprint fails? There is a series called "Steven Universe Future", it has animated, short (14 seconds) credits, even after changing min credits duration down to 10 it wouldn't detect it.
I realize that I can manually set credits detection to black frame just for that series, but it would be nice for there to be a fallback by default if there isn't one.
