GH4 and "Blackmagic Video Assist 4K".
Has anyone tried out this combination yet? I need a new monitor and one with an added 10 bit 4K recorder might fit the bill.
However I remember that Panasonic had to bring out a firmware update to deal with the Atomos series of 4K recorders, and so something similar may be necessary here. Ron |

Re: GH4 and "Blackmagic Video Assist 4K".
Do you know which firmware version the GH4 needs for the Atomos products? I just got the Ninja Flame and output 10 bit 4K with no problem on firmware v2.3. Smooth as butter.

Re: GH4 and "Blackmagic Video Assist 4K".
Just tried it on mine. Records wonderfully. Just remember to turn off the info display, otherwise... The BlackMagic Video Assist 4K is a nice bit of kit! I'm going to test it out for a greenscreen shot to see the difference between the camera's recording and the BMVA4K's ProRes recording. I'll do both 4:2;2 8-bit and 10-bit output... though 10-bit won't record internally on the GH4.
I'll try to keep y'all posted... |

Re: GH4 and "Blackmagic Video Assist 4K".
I did a quick and dirty test using the Blackmagic Video Assist 4K recording from the GH4 in 4:2:2 8-bit and 10-bit mode. I recorded internally (in 8-bit only). It was a quick and dirty shot just to see if I could discern any difference.
I shot in front of a poorly lit green screen with me running the camera and running in front of the camera, so... I'm not showing it! But, playing with the image, the 10-bit footage from the 4K looked good to my eyes and played well within Premiere. I screwed up the exposure because I was outside trying to beat the rain. The 8-bit looked just as good. I'll try to post again with images this time, in a few days. Basically, the GH4 plays really well with the Blackmagic Video Assist 4K. BTW, the 7" screen is awesome! |

Re: GH4 and "Blackmagic Video Assist 4K".
Just updated my BMVA 4K to the 2.0.1 firmware. I can receive signal via the 59.96 NTSC frequency but not with the 24.00 freq. Kinda a mess... But I can still record in 59.96Hz @ 60fps

Re: GH4 and "Blackmagic Video Assist 4K".
Can you downscale to 1080p with the video assist? What about applying LUTs?
