the APS-H is closer to Super35 - which is cinema 35mm. Red is kinda doing the same thing: the 5K 12fps STILLS is the full sensor area, where the 4K video recording part of the sensor is Super35 sized, which is close to the APS-H height. Also, RED does the 5K, 4K, 3K, etc.. difference by using a smaller portion of the full sensor, as opposed to taking the whole sensor and downsizing like the 5D2 does. Make sense now? That's why they have the disclaimer.
