I guess the post says it all!
The dash cam video is very grainy even in dawn, when it is bright and sunny.

My 70mai dash cam pro runs 1.1 Firmware , from factory.
Is this because of the fact, i have a transparent sun-film on front windshield?
I have installed a "Felt" dash-board mat as well, to take care of the reflections!
I do NOT have a c.p.l filter.
Will a firmware update help in improving the video quality a tad bit?

Please review the video attached and share ur feedback!

need to see the original file to judge quality, YouTube compresses the video, looks as expected based on the sample you shared though

OT: i am hard pressed to think of a country where a dashcam are a more valid investment. :eek:

@kamkar,

How do i change the video footage to a bigger format? did u mean 4:3?
I dont think there is anything called 3.4 aspect ratio.

What firmware update are u on running? Is there a procedure to change ?

IMX335 is a 4:3 sensor IIRC.

for whatever reason they've decided to do 4:3 aspect ratio (2592 x 1944 resolution), bigger numbers for marketing purposes at the expense of maximum sky and dashboard, maximum waste of encoding on useless material, strange choice but it's a Chinese company, sometimes the thinking is different
