I thought I would let you do the math… 😉
Assuming 23.976fps at the highest quality rate the camera offers (24 Mb/s), then it is a matter of ratios:
Going to an Avid native LongGop of 50 Mb/s would take up twice the storage.
Going to an Avid NDxHD 115 would be 4.7 times the storage.
I don’t know if I would go from one LongGop to another, and would most likely go to DNxHD 115.
