I'm glad you got it working correctly.
I checked my statement in my B4K review video about the "Time-lapse" setting and I found it to be incorrect. I added a note to the video's description section to hopefully clarify that setting to viewers of my video.
Note: At 11 mins 41 seconds in the video, I stated the "Time-lapse" firmware setting was to select the number of frames per second in parking mode when the time-lapse parking mode was selected in the "Parking Monitor" setting. That statement is incorrect. The "Time-lapse" setting should only be enabled if you want the B4K normal mode recordings to be time-lapse videos. If you want regular videos for normal mode, make sure the "Time-lapse" setting is set to "Off".
