If we imagine for a moment that it were 24 or 30fps continuous- could that output be used for video as an alternative to the designated video modes? What would make the results different?
- dragonwriter 9y agoThe fact that 24/30 < 60fps, which is the video frame rate (and autofocus rate) in 4K video mode.
- beschizza 9y agoEach frame would be 6000x4000 pixels -- 6K with a 3x2 aspect ratio. 20 fps is almost there (playing at 24fps is a 12% speedup), but how long can you practically record at that speed?
- mikeyouse 9y agoThe image buffer is 241 pictures so it'd be about 12 seconds of recording at 20FPS.
- anigbrowl 9y agoYes, absolutely. The difference would be in the resolution (stills are typically way higher than video), and the fact that you'd need to do your video playback offline. You could use it for video now at 20fps (anything over 18 is adequate if you don't mind it looking a bit stylized) but you're likely to run into data bottlenecks...or maybe not, Sony has historically been pretty good at handling high data rates and the removable media themselves are constantly improving sustainable write speeds.
- Veratyr 9y agoYes. Doing so would put the files in the same class as the CinemaDNG output by Blackmagic Design's cameras or RED's R3D. The difference is similar to the difference between JPEG and RAW in stills. You get a lot more flexibility in post and can usually capture a little more dynamic range. There's a video comparing RAW video to H.264 here: https://www.youtube.com/watch?v=jkSYIzCgdIk https://www.youtube.com/watch?v=jkSYIzCgdIk
