Similar to the DR750X Plus, the new DR770X-2CH uses the camera lens and 2MP Sony STARVIS image sensor for both front and rear in a 139-degree field of view. However, we notice a distinction between the DR770X and the DR750X Plus, particularly improvements in white balance, dynamic range, and contrast in the daytime video.
Like its predecessors DR750X Plus and DR750X, the DR770X’s front camera records at Full HD at 60FPS. With twice the frame rate, the DR770X captures smoother videos even at high speeds, significantly reducing motion blur in your footage.
And as far as bitrate choices go, there are four:
-
Highest/Extreme
-
Highest
-
High
-
Normal
Previous X Plus series restricts you to the Extreme mode and does not allow you to change it. Further examination of the raw video footage shows that the DR770X in extreme mode has a recording bitrate of 25.24 Mb/s, which is very similar to the 24.66 Mb/s from the DR750X Plus in the same extreme mode.
Even with headlights shining on them, the DR770X appears to do a better job of capturing details on the road at night. Aside from its capacity to record at Full HD at 60 frames per second, you can easily tell that the DR770X has less motion blur and better highlight detail than the DR750X Plus - even in high-speed situations.
Moving to the rear, the DR770X-2CH uses the same rear camera as the DR750X and DR750X Plus. However, the DR770X rear camera footage looks clearer and sharper - and this is where the new upgrade comes on the BlackVue DR770X: A new SigmaStar CPU and Image Software Processing or ISP tuning.
If you want to enhance the video quality, the BlackVue DR770X also has the option for a CPL filter which can help in reducing glares and reflections on the front dash cam, which works best when paired with the BlackboxMyCar Aqua Shield - highly recommended for keeping your dash cam guarded from rain, dust, and other harsh environmental elements.
Moreover, like the DR750X-2CH Plus, the DR770X-2CH only supports the H.264 codec. While we appreciated the additional compression provided by H.265, we recognize the compatibility issues that it raises.
For instance, you will need Android™ 5.0+ and iOS™ 11 on your phone, or Windows® 10 and MacOS® High Sierra on your computers to properly play an H.265-encoded file - not as convenient, and otherwise, the footage is not as fluid when streamed.
