Reverse Engineering / Re: UHS-I / SD cards investigation

FYI : 700D/1.1.5 using Danne's Sept11 build with SDoverclock slipstreamed and SD_UHS hack

For reference, I purchased a ProGrade 64GB SDXC V90 UHS-3 Card - looking to exceed the 50-60 MBps Write numbers ive seen posted recently.

Numbers are shown here in the Image. Very impressive results. I'll perform video shooting this weekend and report back my results





Update here;

My goal was to find a way to shoot 720P RAW with the 700D/T5i, what I discovered with the single sample unit I had access to from Prograde was, the camera would shoot 5-10 seconds of footage, and then stop. It would intermittently drop the memory controller after being pushed to the 50 MBps + threshold. I tried this in 2 of my 4 T5i's and it happened on both cameras. Ultimately proving to be unstable even with this top-end SD Memory card.

Having said that, with the SD Hack, this is the fastest SD Card access I have been able to achieve with this Camera.

What usually happens is the recording will just quite, and the camera will prompt you with a message, "recording has stopped" something like that... At least on the T5i that's what happens..

Great to see another 700D/T5i RAW shooter here!

To echo dyfid, that is correct. What your seeing in terms of the red dots is typical of these cameras operating under these circumstances. Its not exclusive to just your camera, so dont feel too disappointed!

The card write speeds are ultimately limited by not just to the SD memory card, but more so the SD memory card controller in the 700D/T5i camera itself. The controller is capped out @ approx 41.5 MByte/sec write speed. So far from what we've seen, this max. speed can only be achieved by use of Photo mode benchmarks, and im not 100% sure if those numbers really achievable in real-world use.

Having said that, the "Video" mode benchmarks, which are again, synthetic, are only able to really achieve 37-38 MBytes/sec.

Take a look at the Memory cards I have tested personally here:

http://www.magiclantern.fm/forum/index.php?topic=12630.0

Ive been able to reach the max. write speeds that have been reported with the 700D/T5i with the Kingston SDA Series cards. They are approx 30% less expensive then the higher-end Sandisk cards, FYI.

Regarding your mention of "playing with the settings" understand that the RAW footage your viewing is exactly that. RAW.

Your best served utilizing professional editing/color grading suites such as Adobe Premier Pro CC, After Effects CC, and  SpeedGrade CC to get the most out of your RAW video files.

Hope this helps
