I’d like to see more people rating different cards for 4K with the GH4. I watched Blunty’s review on the GH4 and he says several cards failed, only the SanDisk cards delivered what they promise.
I have the Transcend 128GB card. It works just fine in the GH4 for everything including 4K video recording.
Would these cards also be good for BMPCC’s raw? 60Mb/s should be enough, right?
I assume you’ve already gotten your answer, but for anyone who hasn’t yet… I just bought the 128GB version for my BMPCC and even though it is the fastest 128GB card I’ve tested using BlackMagic’s Disk SpeedTest (64MB/s write), it does not work with the BMPCC. It would start (for a millisecond) and then stop immediately. It would create a folder for RAW content, but record no content at all. I’m assuming the connectors between the ADATA and the BMPCC don’t work with one another. It’s possible I got a faulty one, but since the ADATA works to record video on my Panasonic GX7, I would assume it’s just the BMPCC being finicky.
