Sony A7S3 rolling shutter

I’m trying to figure out what type of rolling shutter readout the A7S3 has. Top to bottom or from the middle towards the edges? I’ve been searching all over the Internet, but can’t find a single answer. I use the Gyro data that the camera records to stabilize ProRes raw footage in Gyro flow because catalyst browse only allows you to stabilize internally recorded files and there’s way more flexibility and adjustability with Gyro flow. One benefit of stabilizing footage with gyro data is the ability to remove rolling shutter on fast whip pans. I know that the read out time is 8.7ms in 4K 24-60fps but I can’t figure out how the sensor actually reads those lines. There’s an option to choose top to bottom readout or middle towards edges readout in Gyro Flow and I can’t figure out which one to use for the best results as I haven’t gone out and done tests. Does anybody know the answer to this? Thx.

Might have a little more info on sensor readout. CineD is a good site generally for camera testing using the same methodology etc. Not that they are without error or bias I'm sure.

You aren't 'removing rolling shutter' with Catalyst, you are using software to try to compensate for the distortions caused by multiple sources (the gyro data specifically compensating for the camera movements). Rolling shutter is quite low in the A7S3. You aren't going to find a consumer camera with one much lower (full frame). In S35 you might be getting better RS on the newly released Fuji X-H2S; but then you are giving up Sony's stellar video AF.
