Write speed of the Pro Duo?

[Paul's Dashcam]

Is the combined write speed of the 4k Pro Duo around 30mbps?

Are you referring to the bitrate? If so, on high, I believe just the front camera is around 60Mbps. Rear I think is around 16, just like the regular DUO.

I'm going to try a a well priced memory card that says will write at 50mb/s so I think all will be good.
