Someone commented earlier about a problem with the BlackMagic Video Assist Recorder/Monitor stuck capturing only 1080/60p. This is actually a problem I ran into a while ago even on the Atomos Shogun, so the problem is not with the BMVD, it's with the Sony A7RII and Sony A7sII.
Even if you set your HDMI output to 1080/24, it will only output 60p 'if' you have your camera recording set to 4K/24. In order to fix (more like workaround) this issue, you have to change your camera recording to 1080/24, and then your HDMI will output properly.
It's annoying, but not a big deal if you know how to work around the issue. So I just wanted to clarify that the issue is not with the BlackMagic Video Assist Monitor.
The monitor has been great over the last few days, and i'm excited to use it more but my SDXC cards aren't fast enough. I'm getting dropped frames when recording 60p footage. Anyone have suggestions on what you're using for 60p footage?
