RAW 4K Capture Feature Coming for Frame Grabs? [CR1]

[scyrene]

This has its place. It's not going to replace high fps sports/wildlife shooting at the top end for a while yet. There are issues - like wading through the vast amounts of data that could be generated (hopefully software could be developed to help). But still, it has potential, and should be cautiously welcomed I reckon.

If these are video files being created such as .MOVs, then it is easy to import the video into a video editor. Each frame in a video editor can be saved as a .JPG. So, if I want to use a given frame capture for some purpose, then I simply watch the video or jump to the place I have in mind (after all I did shoot it, so I know where to go). I have used many such frame capture JPGs for all kinds of things. For example, after I save a frame as a .JPG I can use a paint program to create a poster using the JPG as a starting point.

As I said earlier, I welcome this and think it has potential. But I have also taken videos for extracting frames, and my experience is it's far less good (for the subjects I was shooting). I can only offer my experience and opinion - like everyone else.

I pull stills from my 4k video all the time. I use Corel VideoStudio (yes, I don't have a $1000000 software, this is good enough for me)


pause video and pull frame

(it gets automatically moved to a folder and saved as a JPEG, you can save as uncompressed bitmap too, I personally don't care, I use JPEG)

8 megapixel JPEG image:

I have also tested if the quality is the same as taking a picture.

If I take a still in JPEG and change it to 8 megapixel, is it the same quality as pulling a frame from my cameras 4k video.

It is, there is no loss of quality. I don't pixel peep my pictures, but I don't notice any difference in quality.

Of course, you are limited to 8mp, but in turn you get..video, it's like shooting 8mp pictures at 30fps with an unlimited buffer.

Thanks for sharing - it's good to have different perspectives on a subject. *But* I must say, a video frame will not have the same quality as a full raw still processed to taste. Until/unless raw video is enabled, even at the same dimensions, a video frame will have more compression, for instance. Depends entirely on what you want the shot for - a lower quality shot of the key moment in a sporting event for a website or newspaper is a far cry from a high end wildlife shot. Some users will find this less exciting than others, but it'll be good to have the option.
