Thanks for posting that video. It appears to be the one you got from the SD card, since an internal timestamp matches the clock in the video itself.
The content isn't the "raw" data—that is, the data coming off the sensors. (And even that has some built-in limitations to reduce the amount of data being sent to the camera's computer.) The video stream has been compressed using the High Efficiency Video Coding standard (commonly known as HVEC, also known as H.265 or MPEG-H part 2.) It's an incredibly hairy and complex specification, which much smarter people than I have implemented in the camera's computer.
So what we're all looking at has already been processed and compressed. How much information was lost during that processing is anyone's guess; the standard probably aims at losing as little information as possible while still presenting a picture that's good enough for the human eyes and brain to interpret. As was noted before, the sound is mono. The video runs at 10 frames per second at HD1080 size (1920 pixels wide by 1080 high.)
cjdelphi, I'm curious to know what tools you used to analyze the video frame by frame, and which video you used for your analysis.
For me, I played the video using VLC and used Pause/Next frame to get the frames. I compromised by using a screen capture to save a copy of the frames I was interested in, using JPEG format, which means I may have lost a little bit more information during that conversion. If I really wanted to, I could use ffmpeg to dump the frames of interest as TIFF files. They'd be pretty large, but I'd know I'd be getting the best the MP4 file has to offer.
In any event, it's very interesting comparing the last frame (number 10 of 10) of 03:57:14 with the first two frames of 03:57:15. There is very clearly a light source somewhere behind the big tree in the centre of the frame that very briefly illuminates the windscreen, hood (bonnet) and trunk (boot) lid of the parked car, reflects off a panel of some sort in the house in the background, backlights the leaves in the tree in the centre of the frame, shines on the top of the bush at the end of the walk on the right hand side, and the walk itself. The light source appears to be high (the upper leaves in the tree were backlit, but not the lower ones) and to left.
The source could be a light on a utility pole. I see some evidence of such a pole in the background: there are three vehicles in the midground, which I'll number going from right (the most visible one) to left. It looks like there's a pole behind the roofline of #2. Am I right? And if it is a pole, is there a light on it to illuminate the parking lot?
