I have found something strange, I dont know if this could be a big problem.
I benn shooting with a red one. The camera guy has tranfer all the clips to hard drives, I did a back up copy as well. So I open the folder and see diffents folders, each contains a different. inside the folder theres is the R3d clip in question and then the proxies, so far this is the normal thing. Some of the folders, in instead of containing one clip and the proxies, they contain like 6 or 7 times the same repeated R3d clip, and then the proxies. You see the name of the clip plus 01, 02, 03 etc.
When I check propertes , the weight of all these repeated R3d clips is always 2,15 Gb. I can playback then in red cine and its seems to be OK, they are all the same clip, but the weight can´t be 2, 15 GB. I see half of the material has the same problem and it is the same in the back up copies with the same clips
That's how RED video files work. Because of some limitations with the format of hard drives limiting themselves to single files no bigger than 4 gigs to be compatible with both Windows and Mac, RED has opted, like many camera manufacturers, to span a video over many connected clips. As to why the RED ONE splits them in 2 gigs instead of 4, I have no idea... it may have to do with other engineering issues with the camera; Epic and Scarlet footage spans 4gb files if I'm not mistaken.
Totally normal. It's also why it's highly recommended to copy the whole card structure much like AVCHD/P2 camcorders.
