I'll be recording a surfing competition using 4K60. Camera is rated for 25 minutes in 73F weather. But it will be 95F with no clouds at noon. How long do I have before it shuts down? How long to do I need to wait for it to cool down? If I wait 10 minutes to cool down, how long will I be able to shoot again for (it's 10 minutes @73 but it's 95F). Anyone can answer me right now?, in exact minutes?
Then you’ll be using the wrong tool for the job. I feel like you’re being deliberately obtuse. Use one of the other non-limited 4K modes, or rent a video camera designed for the job you have.
