What causes moire effect?
This effect is called moiré and is caused when a fine pattern in the subject (such as the weave in a fabric or very close, parallel lines in architecture) matches the pattern of the imaging chip. In order to reduce (or eliminate) moiré, a special anti-aliasing filter is mounted in the camera.

moiré pattern, in physics, the geometrical design that results when a set of straight or curved lines is superposed onto another set; the name derives from a French word for “watered.” The effect may be seen by looking through the folds of a nylon curtain of small mesh, or two sheets of graph paper twisted 20 or 30 …

What are the specs of the Sony a7r IV for video?
There have been no improvements in the specs when shooting video in the a7R IV over the a7R III. The camera can shoot in XAVC S HD, XAVC 4K and AVCHD. The top resolution is 4K 30fps with a bit-rate up to 100 Mbps. The bit depth is 8-bit regardless if you capture internally or externally.
What is the bit depth of the a7r IV?
The bit depth is 8-bit regardless if you capture internally or externally. When capturing internally, you get 4:2:0 color space, but it steps up to 4:2:2 when sending video out the micro HDMI to an external recording device. New to the a7R IV is the ability to capture both internally and externally at the same time.
Is the Sony a7r IV a hybrid shooter’s dream camera?
Plus, it has no record time limit. While the codec, frame-rate and resolution options for video haven’t changed since the previous model, the added benefits to still shooters elevate the a7R IV to the level of hybrid shooter’s dream camera. We’ll explain why in this review.
How many photos per charge does the Sony Alpha 7R take?
The Alpha 7R is rated for 340 photos per charge using the EVF, and you’ll get less if you utilize the LCD and Wi-Fi extensively. A second battery is a must for this camera, and Sony should have included a charger so that you could recharge that battery while shooting with the other.
