They manage to do it (just sound, not keypresses) with a 60fps DSLR camera at the end by examining the rows of the video - does this mean that for any videos already in existence, sound can be decoded from the images?
- singularity2001 8y agoFor any old 60fps homemovie of your potato chips: maybe.
- aaaaaaaaaab 8y agoNot for handheld videos.
- pbhjpbhj 8y agoWouldn't you be able to filter out the camera motion, as long as the movement due to sound was fixed relative to something in frame?
- aaaaaaaaaab 8y agoI would say the motion blur and the rolling shutter effect would overpower the subtle vibrations due to audio.
- kibibu 8y agoRolling shutter is exactly why this works. Its not a complicated paper, give it a go.
