How do you take a great still photo with your video-enabled DSLR camera? That's easy, shoot in photo mode. You'll get the best quality and even the option of using a raw format. But what happens if you've got the perfect shot, except you're in the middle of recording a video clip? The good news is that you can export stills directly from a piece of video. There's just a few limitations.
Resolution limitations of video
You might be thinking to yourself “Isn't video really low resolution?” Yes, when compared to the native size of photos taken with your DSLR, video pales in comparison. But for many uses, such as web or newspaper, you can get enough pixels out.
Currently the highest resolution you’ll get exporting a still from a piece of video that originated on a DSLR is 1920 x 1080 or approx 2.1 megapixels. While you aren’t going to make any panoramic prints of those frames you can still find a lot of great uses for them. If printing at 300 ppi, you can extract a frame that is about 6.5 X3.5 inches – in fact a lot of the figures that you’ve see in this book are from video clips.
