It was for the Mavic, it was done by a member on the mavic group on facebook, I take no credit for it, written by Roman Hug
There have been quite some discussions about the best possible resolution/framerate to record video with the Mavic. So i did a test within the same conditions for all res/fps combinations, pointing the cam of the Mavic to a test picture and did not move the Mavic and did not chance anything except the res/fps settings.
There has been the rumor you should shoot in 2.7k because it uses the same 60.000 kBit/s for storage than 4k. Thats not true.
The most importand first: Do NOT shoot video in 1080p 60fps! Even with the high kBit/s. 1080p 60fps does use a algorithm to work together with the upcomming DJI googles and push the frames of the picture as fast as possible to the video transmitting system and to the screen in the googles. Therefore the algorithm for 1080p 60fps is optimized for pure speed and looks awfull if you want to use it for video recording.
4k will record with about 60.000 kBit/s, 2.7k with 45.000 kBit/s and 1080p with 40.000 kBit/s or lower.
The " kBit / frame " shows how many kBit data you have availible for every single frame to storage information about the picture in. Higher is better.
Update:
I did not include the slow motion fps like 1080p 96 because they are not for "normal" video usage and have a signifcant lower quality in bitrate. But i did test them. For example, the 1080p 96 fps does record with around 15.000 kBit/s because it streteches the video.
If you record 10s Video on the Mavic in 1080p 96fps it will use the 60.000 kBit/s and strech them x4 so you will have a 42s Video with 1080p 24spf and 15.000 kBit/s on your hard drive.
Maybe someone finds this usefull.
