The converter options are designed in a way to easily convert incoming messages with specified serialization format into another outgoing serialization format. This is to allow rosbag to record data in a middleware agnostic serialization format. DDS has e.g. a serialization format called CDR, but other middleware such as iceoryx et al might use a different one. The converter plugins in rosbag2 allow you to convert from one into the other with these options.

If they are set equally and correspond to the locally used RMW implementation, no conversion is being done.
