Pho­tos from video

Mac Format - - APPLE TALK -

I am think­ing of up­grad­ing from an iPhone 5 to a 6s. I was in­trigued about the abil­ity of the new phone to record 4K video. Will I be able to grab a frame from the video? I have a Pana­sonic stills cam­era that al­lows me to record 4K video and then se­lect a frame which is saved as an 8MP JPEG. Does the new iPhone have the abil­ity to do this, or do you need a sep­a­rate iOS app to do it? John Var­coe You can tap the white cir­cle in the bot­tom-right cor­ner of the screen to take a still pic­ture while you are record­ing, just like you can on your iPhone 5. On the 6 and 6 Plus, this will only give 4MP pic­tures, even though the cam­era nor­mally takes 8MP pho­tos. How­ever, the 6s and 6s Plus will both cap­ture 8MP stills (3840x2160 pix­els), even while film­ing 4K video.

That only works while you are record­ing video. You can’t go back over ex­ist­ing footage and ex­tract a sin­gle frame. The video footage is highly com­pressed, with im­age in­for­ma­tion spread over sev­eral frames. To re­build this data into a sin­gle, full-res­o­lu­tion im­age you’ll need some ad­di­tional soft­ware. Shutta (free, https://app­ looks like it will do the trick.

The new­est iPhones can take high-res­o­lu­tion stills at the same time as shoot­ing 4K video.
