What faults are likely to occur when filming while using an SD card whose write speed is not fast enough?  I am filming in ProRes 422HQ 2160 P 50 with a Sony Tough card 256GB write speed 150MB/s and the results look good with no dropped frames, but are there any subtle errors which I don't notice?

Correct answer Averdahl

Corrupted files that sometimes wont import, corrupted files that cant be rescued, corrupted frames, audio dropouts, video/audio sync problems.

 

Check the camera manual for specifications for what cards to use. Cheaping out on memory cards will sooner or later bite back.

Doesn't the manual tell you which cards to use?
