The real differences between the Mavic 3 Pro and Mavic 4 Pro are more in the cameras, which have increased the dynamic range and low light capability. If neither of those improvements are necessary for your current type of recordings, you are unlikely to need or see any difference. I fly at dusk where the wider apertures are very helpful, especially when returning in the dark. I can fly later longer without significant loss of quality. Most of the rest are ergonomic improvements with the RC Pro 2 and 30 second deployment, where the RC and drone both turn on upon unfolding, Free Panos, and true Dynamic Home Point without repeated manual resetting.yep....I have a 4K Samsung TV and the videos I've finalized from the MP3 look awesome in 4K. Every once in a while there is a minor artifact, but generally, it just great viewing. So, when the video looks awesome in 4K, it's hard to believe that it could be noticeably more awesome from the MP4
