Maybe I haven't noticed before, but when I pull still images from a 4K video, it looks absolutely horrible when zoomed in to 100%. I was hoping this is just an effect of pulling from video as my DNG files are crisp and clear.

What I'm not sure about it whether the video is just as crappy, but I can't see it because I don't have a 4K monitor, and should I even be worried about it.

Here is an example of what I am talking about. This was pulled directly from the unedited video, and it looks like garbage.

I have the same issue with images grabbed from 4k. I am thinking it is just the way the camera is. If you don't zoom it will be ok. Pulling stills from videos is alternative because taking a picture is even worse.

The Mavic camera needs strong light to really shine -- check these examples:

You're not going to get decent pixel-peeping out of a video frame grab, and remember, this is essentially a cellphone camera.

typically if you want a still shot take a still the frame grab will never be as good as a picture. However, that being said taking a still frame from a video works great for things like thumbnails for your video I do that all the time. I'd recommend always just taking a picture if thats what you want

In general, a photo will be of higher quality, but in practice, a frame grab can often be "good enough" if you are working with good light.

The lower the light the more compression and/or noise reduction artifacts become apparent.

When I want a picture, I definitely take a photo as a DNG and process it like other photos from my DSLR. These come out great. I was just worried that the 4K footage would be viewed like that on a 4K screen and look terrible. I do not have a 4K screen to test it on, but played back on a regular monitor or television, it looks great.

Thanks for the comments guys!
