A major advance in recent times has been the availability of 4K Video and with that the option to extract a still from that video filmed at 30fps to then save as a 8MP photo. The Panasonic G7 camera allows the user to extract the still in camera which is a great feature and great time saver. The combination of the relatively large micro 4/3 sensor and 4K ensures that you can capture a quality action image.ere is an example of a sequence extracted from 4K video and saved as 3, 8MP JPEG files.. The images appear are in reverse order so the first image shown is the last in the sequence.
