F55: 4K record times

Can any F55 owners give me an idea of roughly how many minutes of footage a 64 gig SxS card will record at 4K XAVC @24?

Devilishly hard thing to track down for some reason and I don't trust my math with the numbers I've seen...Thanks
 
Even some of Sony's own published numbers seem "off".

This is straight from my camera:

33 minutes @ 4k 23.98fps
82 minutes @ 2k 23.98fps
 
No problem. Not really sure why 2k would only yield 2.5 times 4k in minutes though.

Are you renting one for an upcoming project? Or planning to buy one? :)
 
Dabbling with the idea of shooting 4K for my next documentary, which is an 11 hour, three year project.
That's a lot of data at 4K. I figure that would be about 1.6-2 TB per trip. We usually shoot for two weeks or so at a time.

Not sure if I'd buy or rent at this point.
 
That amount of data is not a big deal for me. I can get a case of drives cheap at Costco.
But my editor might not feel the same way. He'll need something a little more robust and speedy.
 
11 hours over a three year span of shooting? That's all? Way to contribute to America's short attention span... ;}
 
I know it is pain in arse, but regarding editing my advise would be to work with decent sized H.264 HD proxies and suddenly 500GB comes down to 80GB. Save working with the originals once it's time to actually worry about a final out.

just my 2 cents
 
Just curious...my I know my editor works on FCPX. What would be the best way to do proxies? With a Sony utility, third party software or would he do them on ingest thru FCPX somehow?
Is there some sort of "automated" process for a large number of files?
Not my area of expertise.
 
I have written guides on how to create proxies using Davinci (http://cinetiny.com/zX06CIz6) and how to create proxies using FCP X (http://cinetiny.com/B5XbjUrH).

Both will process large number of files/clips.

Davinci runs on both PC and MAC but if you need ProRes then you'd have to use Davinci on a mac. PC will give you H.264 files which can be edited in practically anything.

You have lots of options.
 
You can shoot both MPEG50 codec and 4K XAVC at same time.

Takes up more space overall, but simplifies the edit disk space issue, provided you can figure out a way to split the MPEG from the 4K XAVC early on.
 
Didn't know you could do that without the raw recorder. I'll have to do a little research on that if we go that way.
Thanks for the heads up.
 
Yes no AXS-R5 required. Just Sony Pro Plus cards to guarantee that you will actually be able to record simultaneous mpeg proxy and 4k XAVC.

If you are on the cheap and constrained by budget I would not try the simultaneous recording unless you are using 100% guaranteed Sony media cards (ie. Pro Plus).

It will however save you from having to transcode hours of footage later.

You'll have to decide what matches your budget and workflow.
