Capturing still frames in-camera Vs in software

Why would you take screenshots? Do you have a video player that can save frames? IIRC there were a few, ad supported if free, even on Android. I use my laptop for this and mpv video player that can easily advance frame by frame and save frames via keyboard. I also like to take shots on the camera as it's often simply faster than transferring a few gigabytes.

They aren't screenshots per se, there is an option on my tablet within Samsung media player to grab a frame and it's the full 4k version. I used to use my PC for editing but now use an android tablet, and there are no apps that do this particularly well. I'd be happy to do it in camera but due to the size and resolution of the screen it's hard for me to pick the best frame.

Funnily enough on my old Note 4 there was the option within the stock media player to grab a frame and advance forwards and back one frame at a time, and this worked really well. For some reason only known to Samsung they removed the ability to grab frames, and then later on reintroduced it but without being able to advance forwards and back one frame at a time.

I can't see any difference (apart from a lack of exif info) between frame captures I make in-camera compared to those I do on my tablet. I don't know if technically speaking there is a difference. Interestingly those captures I make with the tablet are larger in file size compared to the ones in-camera.
