The usage of drone is to capture view or scenery from the top & high angle (depends on job requirement).
We use gimbal all the time during shooting to make sure video footages recorded is stable and not shaking. Sometimes we use monopod or tripod depends on the project requirement.
We connecting our zoom audio recorder to the organizer PA System to capture and record clear audio or music or speech during an event in a hall or seminar room or any places that have PA System.
Besides that for interview, presentation or testimony project we will use wired or wireless microphone.
We will setup our studio led light during indoor shooting if source of light is not enough (depends on job requirement).
