Just came back from a footage and see that both video files have wrong date: Dec 31, 1979. Checked that the ST10+ settings were correct before and after shooting. It also created (as usual) a couple of corrupted 276byte size files. They were correctly dated, but with wrong timestamp. EDIT; formatted with FAT32 instead of exFAT, problem solved! BTW, two runs where I started/stopped the video capture several times and recording timer showed 14+ mins for one of them alone resulted in one of the the typical 1,89GB files (5 min) and the other 188MB only. Will post that problem in another thread.
