It’s aliasing. You don’t see it on stuff filmed with most consumer cameras because they have an anti aliasing filter over the sensor. If you want maximum resolution, you remove that filter. They could have removed it in post but again it would reduce the effective resolution.
- Darthy 8y agoThat's incorrect. You're thinking of a low pass filter, for which the Red supports a variety of filters that you can switch. What the parent most likely is seeing is bad nearest-neighbor downscaling (e.g bad selection of downscaling algorithm).
- abakker 8y agoMaybe photo vs film terminology? On my canon 5DSr, it is definitely the physical antialiasing filter that is removed to allow improved sharpness per pixel at the expense of greater risk of moire.
