batch-extract ignores (some) parameters

[Goreg12345]

I changed a couple of parameters in config.yaml such as num_frames or frame_trim.

This works with the extract CLI command.

However, when I change it to use batch-extract, these parameters are getting completely ignored and the whole video is processed.

I haven't tried it for other parameters, so it could be the case that other parameters are getting ignored as well which will lead to inconsistent behavior, e.g. when one tries to optimize parameters for his/her experiment and then assumes that he can process the other sessions with batch-extract.
