I just completed a DR970X Plus video with daytime/nighttime video samples from a BlackVue DR970X Plus, DR970X, Thinkware U3000 and VIOFO A229 Pro. Both DR970X Plus pre-production front cameras I have are out of focus. I've been asking Pittasoft to send me a pre-production or production unit that is in focus. Rather than waiting for several more weeks (or longer), I created this video showing what kind of video the initial "production" firmware v1.000 will create. Even though the new DR970X Plus front camera has a f/1.7 aperture lens which allows more light to reach the image sensor, the nighttime video is very dark. It's darker than the video created by the previous generation DR970X front camera with a f/2.8 aperture lens.
I used the default H.265/HEVC codec setting for the DR970X Plus to allow it to create 60 Mbps front camera video files. When configured to use the H.264/AVC codec, the front camera video bitrate drops to 40 Mbps. The VIOFO A229 Pro dash camera that I used for this video was run as a 2-channel configuration with a rear camera. That allowed the A229 Pro to create 58 Mbps H.264/AVC video files for the front camera.
