2. Set the Camera to Stream HDMI signals while recording.
For Sony A7R4 or A7R4A there is a limitation that recording video from the sensor will turn off the signal from the HDMI port. However, the Sony A7R5 has overcome those limitations.
Set parameters to transmit images from HDMI port with 1080p resolution. Then, select a mode that allows video recording while transmitting HDMI Output.
From [HDMI Output Settings] → [Rec. Media during HDMI Output] → [On].
Note: To see more information about the Camera parameters on the Remote screen, you can go to the following section. From [External output] → [HDMI Info. Display] → [On].
In addition, convert the image format of the video record to NTSC so that the HDMI port of the Pixy-SM can read the framerate of the HDMI port from the Camera. When you turn on the camera, a notification about the video recording format will appear.
