What's moodle version of your bitnami-docker system?
What's the moodle version of your 'pure' (native) instance?
Could you install the h5p_mod-plugin in the 'native' instance?
At one point in time, H5P was an addon ... later, it became part of core. The addon:
https://moodle.org/plugins/mod_hvp
shows compat up to 4.5 of moodle core.
If you edit the old servers mod_hvp resources, can you see links to the videos? Were they uploaded to the moodle?
If they were uploaded to the moodle, you might be able to use a combo of mysql DB query of mdl_files table to find contenthash value and then use the contenthash value in a 'find' command while in moodledata/filedir/ to find the video file, then copy that file out by humanly recognizable name where you could xfer it to the new instance. Possibly relink the video?
