Out of curiosity, I downloaded the DJI FLY app, which is made specifically for Mavic Mini. I was surprised that it is working on DJI Spark.
Manual Settings while on VIDEO MODE is working while my Spark is connected. That means, the Manual Settings for Video is already in the app, DJI only needs to do is to ROLL OUT an UPDATE to MAVIC MINI to be able to use the MANUAL SETTINGS on VIDEO MODE!
Thank you for sharing your insights and this informative video. To ensure the stability of your DJI Spark in flight, just a friendly reminder please use the recommended application ( DJI GO 4).
