I always wondered what is the best way to have most decent still image quality with Mavic. So I did some comparative tests.
I shotted 1 photo automatically saved in both dng and jpg. Then I took a 4k video (3840 × 2160 pixels) from the same position (and direction). On a Mac, I extracted a frame from the movie with QuickTime and I saved this frame with Apercu both in png and in jpg format. All these at same exposure with Auto Exposure locked. I assembled the details in the image following.
On this comparison basis I can observe that the far best image quality is the DNG image. After comes the jpg encoded image not so good in term of crispness and ev exp. range and the jpg artefacts are too pronounced . The stills have a resolution of 3000 x 4000 pixels.
The extracted movie frame has only the resolution of the movie used (3840 × 2160) and the jpg artefacts are not too pronounced. Saving that in png or jpg changes nothing. the result is honest.
Sometimes I have read that the images taken with the camera are actually extracted from the movie. Although that could be done with the Mavic, the quality is far less than the photos processed in DNG.
My regret is then that while filming you have to interrupt the operation to take photos and restart the filming process. Having a poor old brain I forget time to time to push the trigger…
As I am on the way to express some wishes may I add that I’d like that taking photos and filming should be non dependent and that we had the possibility of automatically take photos at intervals. (Some cheap action camera do this)
Don’t be fooled, the Mavic as it, is for me a real source of pleasure and wonder.
Thank you for your comments and corrections.
