Last week I was sifting through some sample footage from the DR970X, DR900X Plus, and A139 Pro. Here's a few screenshots to get an idea of what I've been seeing so far. Still early on and I have a lot more samples to sift through, but just wanted to share some initial impressions.
The DR970X footage is surprisingly grainy. I suspect it's due to limited bitrate and thus heavier compression while moving. I'm noticing the Blackvues are struggling to capture plates whereas the new A139 Pro (with more than 2x the bitrate) can grab them.
Much better results from the Viofo, particularly on the front license plate and even the bushes on the left side of the screen. It's set to max bitrate and HDR on while I compare to the Blackvues. You can enlarge the image to get a better sense of details.
I'm also noticing times when I get better results from the 900X Plus than the 970X. Notice the differences in the front plate detail on the left and the green street sign on the right.
Looking through some nighttime comparisons, the dynamic range of the 970 is definitely better.
The 970 does a much better job of capturing plates when headlights are shining on them.
A tiny bit of movement though and it’s a different story. GPS is showing 10mph as I pull up behind the vehicle at the red light, though it’s even slower given the GPS lag.
If you match vehicle speeds with other moving vehicles, it works better.
So the 970 is looking like an improvement in the dynamic range department, but it really seems to want ideal conditions. I wanna focus first on DR900X Plus vs. DR970X and I'd like to look at DR970X vs A139 Pro as well separately.
Still a loooot of video to sift through in different conditions, but here's a quick preview.
