Does video grain occuors usually even in broad daylight? Is it normal?
I tried to record video even with lossless Ut video via Camlink 4K HDMI to USB3 adapter, but the grain is the same even in broad daylight.
I used Sony Ax700 and Ax53 camcorders
The result is always grainy.

Watch the pattern on the blue Sky.

Watch this short video, especially the blue sky and flat homogenous surfaces produces that: https://sendgb.com/S7HfZKzm1TA
Turn down the gain. Most decent camcorders will go to at least -3. (FWIW I don't find the small amount of noise distracting at all, indeed it makes the image look filmic.)
Yes it is true, this phenomenon is less signifficant is longer slower shutter speeds even on tripod. This is true all of my former camcorders too. But what is the cause of this phenomenon, practically in all of my cameras (let it be Sony Canon JVC, or Panasonic), and it exists even with lossless HDMI recording too.
Did you try this with your camrea in 8bit 4:2:0 recording? Flat surfaces and Sky became a bit grainy in faster shutter speed, even in blinding strong bright sunshine too...
Gain level was zero 0 db, and it always happen in blinding bright sunshine on the skyand flat simple surfaces. All Camcorders what I ever had produced that with zero db gain in bright sunlight over around 1/100 shutterspeed.
Here is an other sample file about it: you can download it from here: https://transferxl.com/08gRrbT1ZCxmt
All image sensors produce noise.
Pay particular attention in this article to gaussian noise and the sensor effects.
If it's any comfort, it appears you are doing the best you can with the gear you have. Focus on the things you can control. Any distracting noise you have is more than overwhelmed by your distracting shaky camera handling.
