So it's time for the semi annual discussion about going completely tapeless at a place I work. I've heard they are considering Sony F-3's. These are reality shows with a ton of 24/7 footage for 3 weeks on 9 plus cameras. I see in the manual that the Sony shooting to cards is 4:2:0 and the Panny DVC ProHD is 4:2:2. With outboard recorders the Sony's can be 4:2:2 or even 4:4:4 over dual link. I see the F-3 data rate is 25mbs or 35 mbs while DVC Pro tape can go up to 100mbs. I've read here that these data rates aren't always a proper comparison based on more sophisticated compression schemes etc... Can anybody give me some workflow comparisons and quality comparisons. It always seems to come down to the savings in production they believe will happen but the back end of post has more hours and costs associated with the tapeless approach. Given we already own the tape decks I always disagree with a jump to completely tapeless, but perhaps I'm just an F'ing idiot about this. Please set me straight.
On our last production the cost to archive to LTO just 3 surveillance cameras shot to file was in th $8,000 range and we own an LTO drive/recorder already. Now that's just 3 feeds so I don't see how if all the cameras were files we'd be saving money in the long run given the need to send the source material to the network when all is said and done. I personally like the built in archive media that XDCam disks provide. Forgive my ignorance but doesn't Sony offer cameras with the sensor/look of the F3 that record to XDCam disks? Any suggestions and insights would be appreciated.
