Hi Tomasz, >The change of register values itself doesn't give any information about what is changed. Could you explain the following: >- What is the "crop" in this case? The new crop is (0,8), (4255, 3159). >- What value was it set to before and why was it wrong? Old crop was (0, 0), (4255, 3167). With this crop, VTS < 0xC9E was resulting in blank frames sometimes. But we need VTS < 0xC9E to get ~30fps. >- What is the new value and why is it good? With new crop as above, VTS 0xC8E is supported and yields ~30fps. Chiran.

Previously, the sensor was outputting blank every other frame at 4224x3136 video when vblank was in the range [79, 86]. This resulted in video flickering. Omni Vision recommends us to use their settings for crop start/end for 4224x3136.
