why is slow motion video only 720p?

Why is slow mo video limited to just 720p? Why is it that the iPhone 6 can't capture 240fps in 1080p? Even with 60fps, couldn't they have done a pseudo-slow mo at 1080p?

I'm pretty pleased with the iPhone 6, but I sometimes wish the camera could be even better!

Well you can do a DIY 1080p slo mo by exporting to iMovie and slowing down the whole thing to 2x, that'd give a slo-mo at 30 fps :)

240 fps at 1080p requires one hell of a lot of CPU power. The A8 doesn't cut it for now.

I'm pretty sure the A8 can handle that but the file sizes would fill up your phone rather quick. Nevertheless I think we should've had the option for at least 1080/120p. Even the go pro can do that now.

We should be grateful iPhone has slo-mo mode (even in only 720p) for us to play with. This is not an action cam, if anyone want more specific video modes, go get a more specialised video cam. What's next? We expect iPhone able to wipe our arse after toileting? :rolleyes:

It's not all about cpu power, that takes a lot of bandwidth to move all those pixels from image sensor to the storage. High bitrate needs fast storage.

It probably has to do with light. Filming in slow-mo require a good amount of light to make the shots look good. The A8 probably doesn't have any issues shooting 1080p in 240 fps, but a higher resolution would require even more light to get satisfying results, which I think it's something they're saving for a future improved aperture and optics.

It depend upon the CPU architecture. The one embedded on your iPhone might be capable of only 720p. But in the future they may record at 1080p.
