If a phone can have the shutter speed set to 1/4000 of a second, why can’t it record video at higher than 240fps?
In: Technology
A phone can take a still image with that shutter speed, but to do it more than 240 times per second also means you have more images to store on the phone. Moving those images from the sensor, to the the phone memory, can be a bottleneck to performance. Even high end dedicated DLSR or mirrorless sports cameras like the 20 frame per second Sony A9 have limitations because they have a bottleneck moving the photos onto the memory cards. Very high frame rate video cameras exist but of course the faster they are, the more money they cost. There are other complications also. For example, capturing an image at 1/4000th of a second shutter speed usually requires a lot of light. If you watch the slo motion channels on youtube, you may notice the super slo motion clips are darker, because they are using such fast shutter speeds. I hope this helps.
