Blackmagic Pocket Cinema Camera 4K

Recommended Posts

Last weekend I shot a concert with my friend, myself on the GH5 and him on the Pocket 4k. After the first rehersal when we were setting up the shot, he came up to me and said "you know what the lights are all over the place so I'm just gonna set the exposure for the darkest moments and shoot BRAW so when the lights hit you'll be able to just bring down the exposure with ISO setting". I didn't know too much about shooting on the Pocket so I agreed and off we went.

 

Well, it turns out when you shoot above 1250, you can't go lower than that since it's when the second ISO gain engages. It's something I had no idea about (since I shoot on the GH5) and he neither (since he never shot above that before). Now I'm stuck with overexposed shots and an understandably mad client. So learn on my lesson and don't do that.. Or you know, read the friking manual like you should.

That´s unfortunate. When I´m recording concerts I´ll expose for the brightest moments or at least for the spotlight on the singer. Those animated light-shows can really be all over the place, but that way I can have as much control as possible. Thanks for sharing that lesson, nevertheless!

Yeah he should've done that but relied too much on the RAW thing and that was the result.. 

On the other hand why is BRAW settings not working on this clip? Can't select anything

Up at the top, click "Sync * A005_12070220_C002.braw"

Then there are no BRAW settings since I'm targeting the timeline clip, not the master one. 

 

I've found it fixes itself after restarting Premiere and reimporting the clip but then for some reason breaks again after a couple of minutes.

Ouch, lesson learned.

This is also a quirk of the dual gain circuits on the Pocket and GH5S. Sometimes, on the GH5S, I get better results (noise wise) by bumping up the ISO to engage the "high" circuit and then adjust exposure down. I loose DR but in a lot of those cases DR doesn't matter that much (low-light or not a high DR scene).

Yeah the high end of the low circuit looks terrible.

FYI the new BRAW plugin for Premiere 1.6.1 work a lot better, no more render issues and the panel doesnt seem to stop working as often as it did on 1.6

Just curious, why not do your color in DaVinci?

Although I'm not the person you asked, I often edit in Premiere and on those projects, I find it much easier to grade in Lumetri rather than round tripping. This way, you can do a rough edit, rough grade, fine tune the edit, adjust the grade, tweak the audio, tweak the grade, add titles, tweak the grade leave it over night, tweak the grade with fresh eyes and then export. 

I'm sure it's different for everyone, and workflows differ, but rarely am I totally happy with my first grade, and even if I think I am happy with it, watching the project again will prove myself wrong. If I had to roundtrip for every pass I'd waste even more time for not very much gain.

For this reason, when I can I also edit in Resolve, but due to client criteria, that's not always possible. I'm also much quicker with Premiere than I am with Resolve and when your workflow wastes as much time as mine, claiming back as many seconds as you can really helps.

All I really do on this project is mess around with the RAW settings, slap the FilmConvert on and call it a day and I don't really want to buy another version just for Resolve. 

Plus I'm so much faster editing multicam shoots in Premiere than I am in Resolve and if I can keep the entire project to one program I will :)

Does anyone know the exact crop in the super 16 mode?

This thing looks useful...

5a7d398f8f34de0001ef4be5_Sensor-chart-8_

So, S16 looks like it's a diagonal of 14.33 and FF is 43.27, which makes the crop factor of 3.02

Thanks, I asked because the OG Pocket was often referred to as having a S16 sized sensor but the actual crop factor was a touch less at 2.88x so I wasn't sure if BM followed the traditional S16 crop in the P4K or the OG Pocket crop of 2.88x.

They're so close to each other I'd suggest confirming somehow, rather than relying on the accuracy of their marketing department!

With the original they were at the mercy of the sensor but with the P4K its a specific crop they created, so one would assume they chose the traditional S16mm size... maybe @CaptainHook knows?

I find this mode very intriguing because it opens up a slew of lens options that could soften the look of the P4K. I don't know if you've seen any footage from the Alexa S16 mode but it's pretty gorgeous.

Oh man, I just sold my OG Pocket, otherwise I could have checked and compared for you. Sorry about that. Hopefully someone else around here can double check it.

I appreciate the sentiment. Weirdly enough, I haven't found one sample from the new S16 mode online... I would have thought it would be a pretty big deal since a lot of members at bmcuser were petitioning for that mode since the camera was announced.

Also, is the S16 crop mode only in BRaw or is it also available for ProRes?

And will regular SDXC cards work in that mode?
