The Red can capture footage in a variety of ways, 4K 16:9, 2K 16:9 etc, and they all crop the sensor in different ways. To find out what sensor size you should use, just multiply the pixels of your image by 0.0054 (the size of the pixels on the sensor in mm).
For example, if the camera captured footage in 4K 16:9 (4096x2304) you could calculate the sensor size like this: 4096*0.0054 = 22.11mm 2304*0.0054 = 12.44 mm /Simon 2011/10/10 Misho Ristov <[email protected]> > Red One 0.96 in > Red Epic 1.0885 in > > - > Misho > > > > On 2011.10.10 8:27 PM, Ron Ganbar wrote: > > Hi all, > needing to cam track some Red footage.
