even if you can only play 1080p video if you take a snapshot in VLC you get the full 4k native res file, find a point of interest and take a screenshot and you'll be able to zoom in, video looks pretty ordinary at 1080p but looks good at 4kNow we need a video player with good zoom, otherwise I need a 4K monitor and magnifying glass to read the distant plates!
No need to take a screenshot in VLC, it has a pretty good zoom. Even on my 1080 monitor it can show full 4K at greater than native, so I don't even need the magnifying glass.even if you can only play 1080p video if you take a snapshot in VLC you get the full 4k native res file, find a point of interest and take a screenshot and you'll be able to zoom in, video looks pretty ordinary at 1080p but looks good at 4k
When you say "will offer for purchase soon", taking it that it's not this one. Hope not - https://www.gitup.com/mounts/90-3m-adhesive-mount-for-gitup-git1git2git2p-action-camera.html
And since we're on the subject. My concern regarding the linked mount still remains unanswered.
It is not this one, the new one will be available in 2 days.
My guess is that the capacitor is 5V and will blow up the battery model, while the capacitor version can manage with both the 5V capacitor and 3.7V battery but will charge the battery at 5V causing a fire
That would work, but two problems:Not sure I understand what would happen if you put a capacitor from the F1C into an F1. I can see why you maybe wouldn't want to charge a capacitor to 5.4V in the F1C and then put it into the F1 which is only expecting 3.7V from a battery (or maybe it can handle it, I don't know) but surely if you put a discharged capacitor into the F1 then it will only charge it to 3.7V so that would be OK ?
That would work, but two problems:
- At 3.7V charge, the capacitor will not contain enough power to allow the F1 to close the file when shutting down, so you will have to remember to stop recording and turn the camera off before removing power, so you might as well leave the battery compartment empty!
- After doing it a few times you will forget to discharge the capacitor before installing it, and it is quite likely that putting 5 volts into a camera designed for 3.7 with kill the camera.
I imagine that 3.7V is almost empty, the amount of power stored in a capacitor does not increase linearly with voltage, plus the camera probably can't get the last bit below 3.4V, although the F1 will actually charge the capacitor to around 4.2V. Also, I assume that the F1C firmware will shut the camera down due to low voltage a lot faster than the F1 will since it knows the capacitor will not last long.OK, thanks Nigel.
The second problem wouldn't be an issue for me personally as I don't intend to buy an F1C, just the capacitor. However, the first problem is obviously a showstopper for dashcam use. I'd like to believe that the capacitor has been over-specified so that there's still enough juice from just a 3.7V charge, maybe using shorter file segments might help?
The F1C does indeed shut down much faster than the F1, even though both have the 'dashcam' power mode selected, so that is a difference in the firmware. The F1C shuts down almost instantly, whereas the F1 continues to record for a few seconds.I assume that the F1C firmware will shut the camera down due to low voltage a lot faster than the F1 will since it knows the capacitor will not last long.
GitUp F1C 4K - Rear Camera
Whilst I have been busy testing the Viofo A129 Pro 4K, I have also been testing the F1C as a 4K rear-facing camera.
The matchbox size and low profile of the GitUp F1 camera allows it to be mounted at the top of the rear window. In my case, I am fortunate that it can be stuck directly to the window trim and achieve a decent view. Here you can see it installed alongside the A129 Pro rear camera. Note that when viewed through the rear view mirror, the F1C has a smaller profile than the A129 rear camera.
Sample Video : 4K 30fps / Maximum bitrate 72Mbps / Auto WB / GitUp colour profile
Sample 4K single frame
The Auto WB has a blue colour cast to it. Apart from that, the F1C makes a great 4K rear camera with edge-to-edge fine detail and good dynamic range.
GitUp F1C 4K - Comparison to A129 Pro rear camera
I have angled the F1C downwards with a thin wedge so that the bottom edge of the rear window comes into view. I think this gives a better context for the rear video in relation to the car and its surroundings.
This video was recorded this morning in dull, cloudy conditions.
This is the same video, cropped vertically for comparison to the A129 Pro rear camera. The F1C field of view is narrower than the A129 rear camera. The F1C has a clear resolution advantage, however the A129 Pro has significantly less motion blur thanks to its IMX291 Starvis sensor.
