480p and 480i are the same resolution, only difference is that with "p" the lines of a frame are transmitted in sequence while with "i" all the odd numbered lines are transmitted before all the even numbered lines.
The result is an identical image, unless like with old TV you run your sensor at twice the sample rate and send the odd numbered lines from one sample and the even numbered lines from the next, then the result is that you sort of double the frame rate resulting in smoother motion without increasing the "bitrate", however that only really works if you have no compression, as in old TV, in fact it was a form of compression to double the "sample rate" without losing resolution or needing more bandwidth.
With dashcameras, where we are using the fastest exposure times possible, using "i" would just mess up the freeze frame/frame grabs making number plates unreadable, and also without the slow exposures of old TV/film would fail to actually smooth the motion, it would instead have some unpleasant effects. Also, modern compression algorithms like H265 are not designed to use "i", they have much more sophisticated compression which relies on not using "i".
So the answer to your question is that it should definitely be 480p 16:9, not the same as old NTSC TV. Using "i" would be a terrible mistake!
480 i = interlaced where you have the one frame show followed by other at 1/60th second
480p = progressive frames displayed at same time
Figured we were talking about "P" but you mentioned the standard having been around since 1954. As we wouldn't want a screencap with half a frame! Either way, the cloud video at 480 is pathetic by 2021 standards.
Do all cameras using cloud services (Thinkware, Blackvue, etc) upload at 480p? Is this standard?
