Change image settings at higher resolutions

Exposure, ISO, contrast, sharpness, brightness…I think that's it.

Maybe you could post how you tested it? This is the script I used. It works when I remove the in node for the camera control (lines 35-37) but I just get auto settings.

#!/usr/bin/env python3

import depthai as dai

from fractions import Fraction

# Create pipeline
pipeline = dai.Pipeline()
# VideoEncoder H265/H265 limitation; max 250MP/sec, which is about 20FPS @ 12MP
fps = 20

# Define sources and output
camRgb = pipeline.create(dai.node.ColorCamera)
camRgb.setBoardSocket(dai.CameraBoardSocket.CAM_A)
camRgb.setFps(fps)
camRgb.setResolution(dai.ColorCameraProperties.SensorResolution.THE_12_MP) # (4056, 3040)
imageManip = pipeline.create(dai.node.ImageManip)
# YUV420 -> NV12 (required by VideoEncoder)
imageManip.initialConfig.setFrameType(dai.RawImgFrame.Type.NV12)
imageManip.initialConfig.setResize(4032, 3040)
imageManip.setMaxOutputFrameSize(18495360)  # where does this value come from ???
camRgb.isp.link(imageManip.inputImage)

# Properties
videoEnc = pipeline.create(dai.node.VideoEncoder)
videoEnc.setDefaultProfilePreset(fps, dai.VideoEncoderProperties.Profile.H265_MAIN)
imageManip.out.link(videoEnc.input)

# Linking
xout = pipeline.create(dai.node.XLinkOut)
xout.setStreamName('bitstream')
videoEnc.bitstream.link(xout.input)

    print('Press CTRL+C to stop recording... Use VNC to view video.')

    while True:
        frame: dai.ImgFrame = q.get()  # Blocking call, will wait until a new data has arrived

        if start_ts is None:
            start_ts = frame.getTimestampDevice()

        packet = av.Packet(frame.getData())

        ts = int((frame.getTimestampDevice() - start_ts).total_seconds() * 1e6)  # To microsec
        packet.dts = ts + 1  # +1 to avoid zero dts
        packet.pts = ts + 1
        packet.stream = stream
        file.mux_one(packet)  # Mux the Packet into container

With camera control, this is the log message:
