4K Live Cropping ▶︎ 1080p Pan and Zoom from a Locked Camera Shot

Photo Moment - December 21, 2018

Many LUMIX cameras (GH5, GH5S, G9, and even some point-and-shoots) can perform a live zoom and pan to a 1080p video stream from the 4K sensor while recording a 20 or 40 second clip. Let's see how it works, and talk about where you'd use it!

Nice feature but almost useless for short shots due to limitation of setting up times to 20 or 40sec. I dont get it - why there is no user defined time, or at least more modes supporting 5 and 10 sec? really pitty how this could be very useful function but remained useless.
Thank you, brilliant explanation, I was so confused at first.
Why hasn't someone created a piece of hardware that downscales and crops 4k to 1080p, that allows you to preset positions (like "camera angles"), that has a HDMI 4K input, HDMI 1080p output and a USB for connection to software to save preset positions/ control the positions.

This would be perfect for streaming/recording with the ATEM allowing you to record 4K in the camera, while having a multiple cropped camera angles from maybe only 3 cameras (but it would seem like 6 or 7 cameras) going into the ATEM.

*I could technically accomplish this with OBS using a handful of laptops and Camlink 4Ks, allowing me to use the 4K image, and cropping in on it (or zooming) using OBS and companion software to control it. I could then output a 1080p HDMI signal from the laptop into the ATEM.
@@KLRCAT it’s cheaper and smaller than four cameras
@@photojoseph good point, but I don't see many people using ROI if it stays at that price. Right now it's more of an expensive gimmick.
@@KLRCAT nothing that I know of. Scaling 4K and holding all that in memory is not trivial.
@@photojoseph yeah, I'd be cheaper buying 4 laptops, 4 Camlinks, and doing the same thing using OBS.
Isn't there anything that's less than $1000?
I could technically do ROI inside the ATEM, but it would be down scaling the 1080p signal further.
Look up the datavideo KMU-200. It’s what’s called an “ROI” or “Region of Interest” switcher. It’s what you describe.
this is such a great feature but I could not figure out why Panasonic didn't let you choose the type of autofocus tracking , human or mulitpoint.
I didn't even know about this feature....thanks for the info! Can't wait to try it
Great video thank you for sharing. Can the GH6 do 4K live Crop?
Is 4K live crop available in the GH6?
Unfortunately no, and I don’t know why
do you see this coming to the S1 with a software update?
@@photojoseph Thanks for the information, that makes me feel good about the company knowing they actually listen to their consumers. I ran across your video and all I could think about was product shots and the convince of the Live cropping.
I honestly have no idea. If it’s not there, then I’d suggest contacting Panasonic support to voice your opinion. People don’t believe me but the more folks that call Tech support asking for these features, the more likely it is they’ll be added!
Focus transition mode on LUMIX S5, it was on the GH5, but I can't find it on the S5.
Correct. That feature is only found on the H series cameras, so the GH5 and S1H.
Sometimes when I use this the footage looks great in camera but it looks choppy in Davinci Resolve and I don’t know why :(
Weird! Try my suggestion of re-rendering it out before editing.
@@photojoseph Have a look at the finished thing, this clip starts right before a 4k live crop of the pinata - https://youtu.be/Yn4WnhRr_e8?t=67
Even after export it's not playing right? Very odd. Since it plays fine in VLC, do this — export from VLC to whatever format and frame rate your other footage is in, and see how that looks.
​@@photojoseph The rest of the footage is in 4k, the 4k crop outputs to 1080p so should be fine, I think its a frame rate issue or something - we do a song every week for a quiz my friend hosts, and there's a pinata on the piano that one of the watchers has started saying he really wants to smash it up... so I thought I would use the 4k live and get some close ups, we even put eyes and an annoying smile on it to wind him up! Have a look and you'll see what I mean, I have seen drone footage like this too maybe its 30fps going in a 24fps timeline ? somethings up. IT moves smooth then seems to race ahead a lil then another smooth bit... It is fine for what we are trying to do here for a bit of fun, but Id love to know how to keep it smooth. It plays fine in VLC but once in the edit its funny and after exporting it

Ill try and upload it for you to see
Maybe your system can’t handle the playback?
neat, thank you for the info
You bet!
1. you loose bitrate if you do it in post.
2. It is unfortunatate that this feature doesnt support 10bit 422...
This is sucj a brilliant, simple, explanation of how to use this really complicated piece of equipment which I feel like I have no idea of what I'm doing everytime I pick it up!
Thanks man - excellent video
thanks for explaining. I find this to be a good feature in a pinch but no way replaces the look of a real manual hand held or gimbaled pan/zoom/push etc.
Thank you for making this!
my pleasure!
I really like this feature . Does any Sony , Canon or Fuji Mirroless or DSLR support his feature ? ( i need the final out put at least in 1080p)
Please let me know the models if you know . Thanks in advance !
PhotoJoseph damn love this feature specially for super macro footage as it’s nearly impossible to pan in that close range. Too bad most lumix cameras have a ridiculous crop factor forcing me to move to Sony or Canon
I know the LUMIX cameras support this, that’s all
Surely it's better to do it in post, as you will be filming the whole scene? By cropping in, you might miss something that you could have saved by doing in post?
My pleasure!
@@photojoseph Yeah, really good point. Thanks
Sure, for ultimate flexibility, I totally agree. But a lot of people use it to get the shot straight out of camera. Then they don't have to deal with 4K files, no additional editing, etc. I know some folks who use it for social media stuff, too. Do it all in-camera, transfer to your phone, and post without editing.
best explanation on Panasonic 4k live cropping
Glad I could help!
Very helpful. It doesn't seem like the newest version of the firmware gives you any control over the format. Once you press 4K, it doesn't matter what format rec or quality you're in, and the same with output, it seems to output MP4, AVCHD, 28 Mbps,1920 x 1080. The manual seems to suggest you have a choice of output formats. What's your understanding? Does it auto set the default video to only one flavor of MP4?
Just want to be sure I'm not missing something here.
Thank you.
Which camera? Features are never taken away in firmware updates but not all models have the same options.
I've only just worked out how to find and use this feature (Lumix TZ80) but, can anyone tell me what it's best used for? (Newbie here)
Thanks
Pushing into the shot in camera so you don't have to shoot 4K and do it in post
Wanting a small pocket larger sensor to compliment my fuji x100, I've searched long and hard, the lumix lx100 has the manual control I love, but although a m4/3 sensor an g1.7 at its fastest is lower resolution and doesn't use all the sensor anyway, although bigger than a 1inch, the actual zoom isn't quite enough, I've searched long and hard.
I'll probably get this one over the tz200 simply because in 4k video 37-300 ish is enough, plus its slightly faster at the wide end.
And of course the price, sony rx100 is way to expensive if you want a viewfinder mk111 and above and limited zoom, fractionally wider 24mm but you cant have everything.
I've got DSLR and the lumix fz1000 but they wont fit in a pocket or small bag.
So I'm pretty much sold on the tz100,
Joseph, would you suggest to Panasonic that it would be awesome to add a loop function this would be great for interviews. Setup one camera locked and then live cropping panning back and forth. Wondering anyone has thought off this?
Great idea
I like it!
wish it was possible to change the crop orientation for IG stories
Ahh, I see. Yes, that would be cool. Guess you’ll have to do it in post then. Have you tried LumaFusion? Fantastic iOS video editor if you’re trying to stay mobile.
@@photojoseph
The Idea is to use the in camera 4K live cropping to create a super smooth horizontal pan of the vertical 1080 * 1920 crop.
And if you rotate the camera to do it you loose horizontal pixel width to pan through.
Compared to 3840 in 16:9 you get 2880 tops in 1:1 ratio with the rotated camera.
So while it is possible to rotate your camera, you loose 25% of the possible pan, which is a lot, considering the 4K mode already introduces a huge crop factor.
Rotate. Camera. Here, watch this: https://youtu.be/jjpx1eNfwQk
Well it is amazing
this is an awesome feature.. thank you.. my imagination is stirring with thoughts on how to creatively use this feature... Thank you.
Awesome! I love to hear that.
This is a great in-camera technique. I only wish Sony cameras had this feature. It's like having a slider without an actual slider.
Cool old school, post with 20 pixels raw might be nice too. It can all change anytime with a hard drive direct to the sensor. 20 mp raw direct to raid drives. We love the wait !
Reminds me of director macro media, shockwave beta team here ! I used to sell software to macro media when there was 10 people in the company ! Old San Fran, software days !
Another obvious benefit is that you do not want to deal with 4K files at the time. This allows you to record 10:80 and do some amazing stuff. Also, if I tried to do this kind of push or pan by hand using the zoom sleeve on the lens, there is no way I would get it that smooth. It's like having a digital quick'n'dirty motor driven slider as well. This is so very cool. I am definitely gonna start using it on my G9. Great work man. Excellent demo.
Thanks!
Yes, that was very helpfull. I didn't realise that I could assign the button dial for video functions. So my new setup is: bottom=ex tel conv, top=video record, left=digital zoom, right=is lock. As far as i know the digital zoom also punches in up to the sensor size and then thereafter it interpolates. so i can use the 12mm 1.4 prime as as 24mm 1.4 prime for video. How did you assign the other 3 buttons on the dial? Thanks (update: comment refers to your episode on using 1080p for vlogging)
I’d recommend avoiding using digital zoom. As you mention it scales so that’s not good. The other buttons for me are for stills work on the G9; I think. The truth is I change them a LOT. Just depends on what I’m doing at the time!
Another great feature well explained.
Thanks!
What mode do you use for continuous auto focus in video? "AFC" or "AFS/AFF"?
AFC
Awesome!! ... I love my G9!
I fucking love my G9 too.

Most underrated camera of 2018.
