I have several video frames in 4K 29.9 corrupted on GH4. Was using high end fast Kingston card. This is the first issues I seen with this camera. This makes me unsure of the camera. Anyone had similar issues?
Not a big fan of Kingston cards - I always use genuine SanDisk. Just shot over 220 GB of footage in very hot and humid environments and not a single frame is bad. So unless something is wrong with your camera, I would suspect the card.
