Since the Mini 2 reportedly can shoot RAW wheres as the Mini '1' can not I was just wondering if....................

Thanks. So it is feasible for the Mini '1' then?

RAW files are  essentially the raw data output from the image sensor. They are created by all digital sensors after every shot.   It actually takes more processor overhead to compress the RAW data into the JPEG format then to capture a RAW file.  The Mini 2 is just adding Metadata to the RAW output and writing it to the card.  DJI could have easily implemented this to the Mini 1 but choose not to.

You are right. But nowadays Jpeg compression is provided by dedicated hardware codec while raw requires central cpu usage for data flush. I assume developers afraid overheating because of it and Mini 2 will be equipped with more advanced micro controller for both jpeg and dng support.

overheating while raw saving? why? ? raw saving can be slow, it's not video.

Thanks.....so whilst theoretically possible it may be inadvisable?

Poor (clean) raw data will be not compatible with CameraRaw and other software. I saw this only in Chinese action cameras (GitUp and Sjcam) and those raw files required special soft to convert them into usable dng's. So, raw data have to be placed into DNG structure for better compatibility with various photo software (Cameraraw etc.). If no hardware codec on board then only cpu can do it. I guess it looks this way.

This only my guess and circumstances. I feel my Mini is warm after long flight. So, what the critical temperature could be reached with additional tasks? I don't know. But Dji is prefer to minimize any risks for sure.

DNG generating on CPU is not a problem. It's not real-time video compression into H.264 or HEVC, dng can be produced on CPU, it may be slow.

I love it when technically un-qualified people feel free to make comments like this. Saving RAW images is definitely a slow process, because you have to write full frames of data for every frame of video that exists. Therefore it can be a very difficult thing to do within the speed constraints of the SD card and the associated processing. And into the bargain, you still have to maintain a highly compressed MPEG stream to feed back to the RC control unit for preview purposes.

You just proved your own point.  RAW image files have nothing to do with  "every frame of video".

Yes, you are quite correct, I was thinking of RAW Video....
