Set of patches to add 30s/2m/3m/5m loop intervals:
loop time patches.zip

How to use: Unpack 'update' subfolder from folder named according to required interval time to your card and start normal fw update process (charge, unplug, press right+power buttons to start). Power on and reset setting to defaults.

Use '1m' to revert back to 60 sec loop time.

Any watermark remove hack? THX

[nutsey]

Yep. I've managed to remove the logo. But for some reason the timestamp goes away as well. More tests are needed here.

Hey. Widzę dla mnie bardzo zrozumiały język. Jeśli nadal jesteś aktywny w kwestii 70mai Pro proszę o podpowiedź. Jestem od kilku dni szczęśliwym posiadaczem kamery jak wyżej. Uaktualniłem fabryczny firmware do v. 1.0.9 i przestał pracować moduł GPS. Może podpowiesz jak "wyleczyć" tą przypadłość? Jak konkretnie uruchamiać update z karty. Nie do końca władam angielskim jak należy i nie chcę popełnić błędu - jest OLD MAN... . Jaka paczkę wgrać bez kombinowania by być zadowolonym z urządzenia. Pozdrawiam z Gdańska.

Hi there - amazing work!

I'm struggling with a dash cam that has amazing video quality at low light - but saves audio as PCM which makes the files huge. I capture the audio with another device because the mic of all those action camera and dash cam have horrific microphones, and just use the audio for sync purposes.

Do you know how do you switch from PCM to AAC? And if we are on the topic, do you know how and where to change bitrate and frequency?

Thank you
E

Thank you for all your hard work!

Can you please check what's the file size difference between 1m and 5m ? I presume the bitrate doesn't matter if it's percentages we're talking in.
Is there an option to toggle logo on/off or it is off once you apply this hack/fix?
Where do we choose the bitrate and loop interval values, in camera menu only?
What happens if I connect the camera to the phone, does it rewrite the settings(bitrate-loop time)?

Thanks!

Thx for multipatch and my question is how I know status of internal battery?

[g0nzal3s Junior Member Find all posts View Profile Close g0nzal3s]

Thanks for your work, nutsey. Waiting for Multipatch v2 release!

[SiMo1552 Junior Member Find all posts View Profile Close SiMo1552]

Everything is perfect no more logo and i love the size of time and date. only one small issue with GPS coordinates and speed disappears after 2 minutes of the video.

[nutsey]

Thanks for your feedback!

Nice.

Any ETA for new utility release?

[nutsey]

It's going to happen very soon

[ymangitu]

Hi there, I see in second window screenshot you posted has the option to turn off the stamp. Can we do that? I dont want both the logo and the stamp. Thanks!

Tried to install mod on dashcam, but it says "Update Failed" and then restarts.
Copied "update" folder to sd card, right button+start button, the camera goes into install mod, but after one second shuts down and doesn't install anything. Other times it just says "Update Failed" and shuts down.

Can you please post a step by step guide?
Thanks!

[muniek62]

sprawdź nagranie z kamerki też tak miałem a okazuje się że nagrywa 5min bo w menu nic sie nie zmienia daj znać czy jest OK

[nutsey]

You are doing it right. The patch needs just a couple of seconds to be installed. "Update Failed" appears after you trying to flash it after booting with "update" folder on card (it is deleted during normal startup).

[Surf_Dude]

Thanks, I managed to make it work. Turns out I wasn't resetting the camera to default.
Some values, for info: A 3 minute video, at 2560x1440 res. has ~540-550MB. Bitrate was 24-26Mbps.

[nutsey]

Was it a static scene?

[Surf_Dude]

Yes, it was static.
Now recorded in car, all continuous motion: biggest file size: ~760MB, bitrate: ~35Mbps. All this for 3m video, at 1440p resolution.

Is this camera capable of 60fps? At, let's say 1080p, to keep file size decent enough.
Would there be a way to control EV or toggle WDR on/off?

And there's one other problem: In PAL mode, to achieve 30fps, every 6th(or 7th frame, can't remember) is doubled. It results in a little jerky playback. Can this be somehow fixed? Choosing NTSC results in light flickering during night time.

[nutsey]

Working on these at the moment. Seems like 60fps is not implemented in sensor driver. Probably one of 25fps (PAL) modes can be transformed into 60.

[Surf_Dude]

Great, thanks!

After checking, it seems that the doubled frame in PAL mode is fixed.
I'm pretty sure this was a problem before installing your mod. Can you confirm one or the other?


L.E.:
Back with some feedback, if you don't mind. Tried the mod in night time. The footage looks noisier than before, even in well lit areas. Have you modified any ISO values or stuff like that? But I think despite of more noise, the license plates are actually readable when in the correct angle.
Some info for 3m-1440p biggest file size I had: ~620MB at ~28Mbps.

[kalee]

i cant install mine .
what did you do to make it work?
