1) With FPS override turned off, open the FPS submenu, enable the Advanced mode and write down the two timer values. Repeat for all video modes, and also for photo mode and 5x zoom.
2) Set FPS override to 35 and try all video modes. Write down timer values and make sure the image is normal."
Strange!
One time in M mode in „FPS override“ menu I was seeing „Rolling Shutter“: 214748364.7 us, what is 2147483647 (2**31-1) with point.
One time I was seeing „Shutter range“ 1/-214748... .. 1/-214748...
One time it was impossible to go into ML menu from „live view", without switching off camera.
When I was trying to do video (1280x720 – 25) with FPS override to 35 it was every time video withoud sound.
With second video mode (1280x720 – 30) with FPS override to 35 video was with sound.
I wrote everything what is changed during test exactly, f.ex. '-', '+' and 'x'.
