Adding episode start timestamps to multi episode files

[PaulDaPigeon]

I have some TV shows that have 2 episodes in one file. Googling only brought up information about file naming conventions like S01E01-02 and how to display the title of both episodes.

I'd like to manually add metadata that so jellyfin displays the episodes separately in the library and starts each episode at the right time stamp.
E.g.: E01 0:00, E02 15:42

Does such a feature exist?

Negative. Your options are to use the E01-E02 syntax or use some app to split the files. Handbrake has the capability to split at chapter markers, but that requires re-encoding. I'd have check if MKVToolnix can split episodes, which would NOT require re-encoding.

Highly recommend Mkvtoolnix. Syntax is super easy and can be done by timestamps or by chapters if your media has it. Even has replacement logic for episode numbers which I tend to wrap in a reversed for loop (start at the end of your file set) since you'll always get a counter starting at 1 for episode numbers (e.g., "%02d" would yield zero-padded episode numbers starting at 1). For loop can rename and avoid overwrites if started in reverse order.
