I don't know if this is the most proper place to ask my request because it deals with my video camera and not with a digital camera, anyway please mods move this in the case
I've got a video camera and it can record videos at 2 resolutions: 1280x720 and 1920x1080 and I'd like to know what's the size (MB/GB) of 1h of video recorded at each one of these resolutions. My goal is to buy a proper sized micro SD, I mean I want to get the smallest one which can contain 1h video file(s), in other words I don't want to waste my money buying the largest SD my device can fit in (32GB) to be sure of that.
I've recorded several "small" videos -I mean just a couple of minutes- due to the fact I've got only one small SD and I guessed I could calculate the size of 1h video on a proportional base but my main doubt/problem is the bitrates differs a bit though the resolution is the same therefore I've got final results (1h size) between a too wide range.
Here're some metadata taken both from file properties and from "g-spot" sw about 720p videos (note: sorry for my bad english translation):
file #1
files #2, #3 (only what differs from the above data)
As said and you can see bitrates differs therefore I've got different theoretical sizes about 1h video, I ask if it's possible a more precise result and how.
If you need more data please tell me what and how to get them.
Thanks in advance.
