ProRes and Raw SD

PostWed Apr 18, 2018 3:24 pm

Hey Everybody, I am shooting with a D-750 and will hopefully be getting the new pocket 4k. Right now i am using the SanDisk Pro 64gb 95mb/s SD cards. I am looking forward to shooting Pro-Res and Raw with the new pocket 4k. I'm just curious if these cards will work for ProRes or Raw and if so, how much footage can I expect to get from them shooting 4k @ 24p?
Thanks!

The SanDisk Extreme Pro 95MB/s card can be used for the following formats:

* RAW Lossless recording up to 1080p30
* ProRes recording up to 1080p60 ProRes HQ

For recording up to 2160p30 ProRes HQ you will need:
* SanDisk Extreme Pro UHS-II 280MB/s SDXC
* Angelbird AV Pro 300MB/s UHS-II
* Sony SF-G128 300MB/s UHS-II
* Toshiba Exercia Pro UHS-II 270MB/s SDXC
* Transcend Ultimate UHS-II 180MB/s SDXC

Storage Rates
4096 x 2160
CinemaDNG RAW - 270 MB/s
CinemaDNG RAW 3:1 - 128 MB/s
CinemaDNG RAW 4:1 - 96 MB/s

3840 x 2160
Apple ProRes 422 HQ - 110 MB/s
Apple ProRes 422 - 73.6 MB/s
Apple ProRes 422 LT - 51 MB/s
Apple ProRes Proxy - 22.4 MB/s


1920 x 1080
Apple ProRes 422 HQ - 27.5 MB/s
Apple ProRes 422 - 18.4 MB/s
Apple ProRes 422 LT - 12.75 MB/s
Apple ProRes Proxy - 5.6 MB/s

Storage rates based on 30 frames per second.

That means for a 64 GB card @ 30 fps:
4096 x 2160 CinemaDNG RAW ... 4.05 min
4096 x 2160 CinemaDNG RAW 3:1 ... 8.5 min
4096 x 2160 CinemaDNG RAW 4:1 ... 11.3 min

3840 x 2160 Apple ProRes 422 HQ ... 9.93 min
1920 x 1080 Apple ProRes 422 HQ ... 39.72 min

For 60 frames per second its half the recording time.
Saying "Thx for help!" is not a crime.
