This side by side 28 Mb/s Bitrate comparison between A129 1080P vs A119 Pro 1440P demonstrates improved image detail from both cameras using what should be the standard 1440P resolution Bitrate. My A119 Pro underwent Lens surgery changing the original F1.8 Lens with F1.6 from A129.

Need someone to confirm Parking Mode at 5fps works normally with MOD-8Tm loaded.
The parking mode 5fps is not stable at all. Files of different lengths - from 15 seconds to 1.5 minutes, which can be seen from the file size, as well as the pause time between files.
I did not check on other parking modes.
Video in normal mode records without problems!
Loop Record cycle set to 1 minute

Mediainfo (аn example of one of the files in the parking mode):
File : 44 s. 667 ms. (recorded 268 seconds of real time)
Bitrate: 28,7 Mbps
: 2560 pix
: 1440 pix
: 16:9
: 30,000 fps

Thanks for the detailed Parking Mode testing at 28 Mb/s.
Based on A119S Parking Mode functionality the limit for stable 5fps Time Lapse is 26 - 27 Mb/s bitrate. Was hoping the Pro allowed 28. We seem to have hit the limit.
Parking Mode worked fine at previous 26 Mb/s correct? Can you test 27 to confirm is stable?

Parking Mode 5fps Time Lapse only records clips when visual motion is detected, so if nothing moves zero clips if more activity will keep recording at 5fps until motion activity stops.
5fps Time Lapse does not record continuously so clips will vary in size which is normal.

Yes, I will check the parking mode at 27 Mbps.
While I’ll continue the test for MOD-8Tm for a while, but by some chance the recording resolution today I got 1080p instead of 1440p (apparently, when setting the date, I could switch this mode)
Well, nothing can be done, but today I managed to shoot a video of the storm, which lasted about 30 minutes

Video using Mod 1Tm, but saved to 4K to Youtube to try and stop their spoiling the view. Just 2 minutes long, but pause it at 28 seconds if you can....

Very interesting old school Firebird hood scoop supercharger stack, the colour is shocking but the 1440p resolution 32 Mb/s Bitrate video is perfect and the baseline for all future Dashcams, thanks for sharing this modified firmware footage.
Did you notice an improvement in detail using MOD-1Tm ?

Yes - the improvement is there, and England's temperature might allow me to leave it on in summer with a bit of luck...

Currently testing A119 Pro using 29 Mb/s Bitrate hoping it can produce very similar detail as 32 Mb/s.
Interesting you mention temperature, just about to update my suggested levels and increase the range limits by 5C. I've detected no voltage or internal temperature change using 29 Mb/s.

YouTube's play back Quality Setting for 1440p or 2160p appears depending on Operating System and Browser.
YouTube's higher upload Bit Rates use VP9 video codec, verify codec with right-click on video, select "Stats for nerds".

Google Chrome: VP9 video codec is enabled on all OS.
Linux: VP9 is enabled in Firefox,
Mac: VP9 is disabled in Firefox, thus only H.264 with 1080p will get played.
Windows: VP9 with 2K or 4K depends on the machine

enable VP9 in FIREFOX by setting media.mediasource.webm.enabled to true in about:config

After weeks of testing A119 Pro at 29-32 Mb/s with no noticeable internal temperature change and the recently revealed new Viofo A119 V3 stock hidden 4K video bitrate of 32.2 Mb/s . . . decided to remove all my suggested temperature use limits. As expected the soon to be tested 4K - 3840x2160p resolution A129 Pro WiFi Dashcam increases Bitrate for the much higher 4K resolution to maintain fine details, 32 Mb/s is the perfect level for 2K maximum detail.

I suggest everyone start tracking the price of 128 & 256 GB micro SD memory cards rated U3 for 4K video 90 MB/s write speeds.

MOD-9Tm Some day and night footage. My polariser has gone missing, so I will have to purchase a new one. The footage looks good. Night footage was wet and damp, still a good level of detail. Thanks for the continuing development of this firmware.

Excellent A119 Pro 29Mb/s test footage, daytime video quality is near perfect, I was sure that Bus was going to hit you. The rainy night footage is very good, thanks for sharing.
Hope you can help try the slightly sharper MOD version.

Thanks for the feedback. I did not notice the bus, my wife does the driving :) I will give the sharper MOD a try at the weekend.
