You can use a Blackmagic Video Assist with the Lumix S5II/S5IIx to record BRAW. From what I read here, there's no processing load on the S5IIx's body.

“...If you like BRAW, the S5iix can shoot Blackmagic RAW using a Blackmagic video assist, has incredible IBIS, great battery life and solid autofocus. Braw on it is equivalent to what you get on BMPCC cameras. My Nikon AIS primes look absolutely incredible on that full frame sensor.
Note that Panasonic cameras do have HDMI delay/lag issues but I've been able to work around it and it hasn't been an issue for slower moving content.
…I've used both the BMPCC 6K and currently own the s5iix as my main cam with the video assist so I'm familiar with the BRAW bitrates. Been using BRAW on the S5IIX exclusively for 2ish months.
You get the exact bitrates BRAW would give you at that specific resolution, all the way up to Q0 or 3:1 compression. The video assist has a USB C port for SSD's, basically is a pocket cinema camera without the body, same OS in a monitor.
Affordable, unfortunately the monitor is really pricey Round 600+ USD but it's great as monitor and recorder, 2500 nit brightness monitors aren't cheap regardless.
…The S5iiX does have a fan, it's mounted in the EVF area and I've never had the camera overheat, even on days with 33C 90% humidity.
And I've stress tested the S5IIX in both internal 6K for 3 hours and external raw for 3+ hours. The internal 6K got much hotter as the camera processor was working hard to encode the file. The RAW output had the camera barely heating up, in fact I don't even think the built in fan in the S5IIX was running. Since the camera simply has to dump RAW sensor data over HDMI, there's no processing load on the body. Never once did I get any heat issues, heat threshold set to high. I ran out of my power bank and NPF battery before anything came up and I'm confident it would do well with a full V-mount power system.
What did get hot was my Blackmagic Video Assist, the fan on it was running pretty fast but that's because I had the screen maxed out brightness wise, it's eye searing. And my SSD was extremely hot, hot enough that it felt it could burn me. I was recording 6K Braw 5:1 to a Samsung T7 Shield 2TB. The video assist was giving me a temperature warning but never once shut off, once I reduced screen brightness to 65% it went away.
…(The fan on the) BMPCC4K doesn't get loud, but the 6K's I've worked with do have noticeable fan noise. Thankfully it's not that bad on the video assist.”
r/bmpcc Is micro jitters and vintage lenses a bug issue on BMPCC 6k?https://www.reddit.com/r/bmpcc/comments ... bug_issue/AliTheAce wrote:
“...I use the S5iiX exclusively, and 90% of the time with a BMVA 12G. I have used the S5iiX for sit down interview work and also for run and gun handheld work and the AF hasn't failed me once. My XT3 did a lot worse. You have to set it up right but once you do it's pretty solid. Proper AF modes, human/face detect if you need it and the speed and @@@ responsiveness settings as required.
This time, the Panasonic implementation of BRAW is equivalent to that of the BMPCC cameras. You have highlight recovery, you have all the gamma and gamut options that BMPCC cameras have, with the only exception of ISO, but you can adjust the exposure directly through the metadata in camera raw. The previous S1/H/5 cameras did not. I used BRAW one the old S cameras and it looked pretty zprocessed and had sharpening baked in. They did not output a pure RAW RGB sensor data stream, now the second gen S5's do. I can upload some footage to play with if you're interested. This is after splitting apart the color0channels to inspect under the hood to see if there's anything nasty going on. There isn't. I've worked often with the BMPCC6K and am quite familiar with the files and how they handle. The S5IIX, in my stress testing can handle over/underexposure extremely well, including highlight recovery for channels that are clipped, to a certain point. Yes you shouldn't rely on highlight recovery but in emergency situations in a run and gun scenario it's handy. I still expose to the right before clipping and it's not failed me.
Rolling shutter wise, that's the main Achilles heel I'll agree with but it's not a big deal. If you need fast rolling shutter, drop to 4K S35. For the kind of work most people shoot, which is corporate/narrative style, it's not an issue and is better than competing hybrid cameras. 6K 16:9 BRAW works well for most situations.
Is it perfect? No. But in my experience handling BMPCC cameras for outdoors/run and gun scenarios, they get pretty damn cumbersome.
r/bmpcc Can someone show me the difference between the 4k and 6khttps://www.reddit.com/r/bmpcc/comments ... en_the_4k/AliTheAce wrote:
BRAW on the S5ii/X is finally proper BRAW. You get everything it has to offer, unlike the previous implementation of it on the Gen 1 S series that was processed and had compression applied to it.
Behaves like it does on the Pocket cams without any extra sharpening or processing applied.
It matches what the BMPCC cameras can do and has the exact same controls, with the only exception of ISO in Resolve but that doesn't really matter as you have other controls that do the exact same thing.
Having shot with the pocket 6K, the S5IIX is a good bit ahead. Cleaner shadows, more highlight headroom, autofocus and battery life are pretty damn good and IBIS is very handy.
You basically get a full frame mini Pocket camera with autofocus, IBIS and solid battery. Well worth it if you can stomach the cost of the video assist.
You have to get any of the 12G models to be able to do BRAW. That leaves you with the 5" 12G HDR or 7" 12G HDR.
…ISO is simply a mathematical gain operation, the exposure slider works the same way and you have that in camera RAW.”
r/bmpcc Im thinking about getting the black magic video assist for braw for my s5II how does braw from the video assist compare to a actual black magic camera image wise?https://www.reddit.com/r/bmpcc/comments ... gic_video/
