UPDATE: The LUMIX S1 also has Open Gate, in the form of (for larger-than-4K), there's "6K" 5952*3968 (3:2) 24p as well as a "5.4K" 5376*3584 (3:2) 30p modes! Both are 4:2:0.

What do you think; are you intrigued to start shooting in Open Gate? With the GH6 firmware 2.0 released on July 5 2022, you can even do 4:3 5.8K RAW with the Ninja V+!
The S1 is amazing value, you can pick one up second hand for around 1k which is amazing value for a FF camera capable of 6k internal.
Will the Ninja V+ work with Canon R5 using this 4:3 and later punch in to use 16x9 or 9x16?
🤦‍♂
Man panasonic is so cool lol
@PhotoJoseph So is the same on the S5? I it seen it has 4:3 anamorphic mode with a apsc crop.
This was awesome and I learned something new...Thank you Joseph.
That’s what I love to hear!
Yeah now that I have open gate with my GH6. I can't not use it.
Hehe awesome
NO 25P...👎
Of course it has 25p. And 50p, and a variety of high speed 25Hz frame rates. You switch the camera between 24Hz, 25Hz and 30Hz modes.
@PhotoJoseph Yes but not in open gate...the only frame rates listed were 30P and 24P
@Anthony James ahh — that’s my fault. I neglected to include the PAL rates in the chart. You can download the GH6 user guide and check every rate at every size but open gate IS supported in PAL.
@PhotoJoseph Fantastic...thanks for confirming 👍 Would have been a silly omission if they didn't include PAL frame rates. I plan to shoot the April 2023 solar eclipse with this mode.
@Anthony James awesome. Yeah amazing how much planning can go into a video then I forget something so basic 🤦🏼
Hi 😊 Thank you for this amazing video. Question: Do open gate files take up more data than 16:9 and if so do you have an estimated percentage of how much larger they might be? Open gate for non-anamorphic lens projects seems like a good option to allow for reframing up and down in post while maintaining 16:9. This could be especially valuable for gimbal shots if the camera unintentionally drifts too high or low for a take and a reframing adjustment is needed in post. Thank you sir. 👍
File size is determined by data rate, not pixel dimensions. 200mbit is 200mbit regardless if it’s 1080p, 4K or 6K. You can convert mbit per second (megabit per second) also written as mbps into megaBYTE per second, then x60 to get a per-minute estimate. Don’t forget to include audio but that’s minimal compared to video.
@PhotoJoseph Thank you for the reply. 😊 I didn’t know if 16:9 saved data by not recording the tops and bottoms of the sensor as opposed to open gate, but you have a good point in using the bit rate to look at file sizes. A person can look at the bit rate for each record setting (if they own a GH6) and make a storage decision from that perspective. For those of us who are considering a GH6 but don’t have one in our hands I suppose I was looking at it more from that perspective. Perhaps I can check the owners manual for the bit rates of 16:9 at 4K 4:2:2 10 bit and compare that bit rate to open gate at the same or closest similar resolution and calculate a percentage in file size difference from there. With a percentage difference in file size I can calculate a storage cost for shooting and storing open gate footage as opposed to 16:9 capture to assess if any difference in cost is a value proposition for my purposes. With the cost of high speed media for the GH6 it would be nice to be able to estimate the cost of data storage ownership before going down the GH6 path or going down the open gate path as opposed to 16:9. I don’t shoot for social media, only my own narrative work so open gate would just be a framing bonus (or safety) for me. Thank you for your insightful video and for your bitrate suggestion as a metric for choosing open gate or 16:9. All the best to you sir. 👍😊
@Coby Marcum downloading the manual is definitely the way to go. All the info is there.
Joseph, you looks as mind person, could you clarify me, why panasonic packed extended v-gamut colorspace (v-log) into rec709 colorspace? You can check it in metadata. After that operation, v-log become typical profile as Standart/Natural etc with very specific curve, but rec709 has theoretical 9.97 stops of lights, that mean no matter what you choose: v-log, cined2/Standart (with contrast/saturation -5), you will get this 10 stops maximum. P.S. even sony/canon can choose rec709/bt2020 colorspace for their log profiles.
hey there… I think there’s some confusion here, and I’m not totally sure I understand everything you’re saying, but it’s like this — first of all, Rec709 vs Rec2020 or Rec2100 are just flags. It’s metadata, and means nothing to the actual file. You can flip that flag in the NLE, and since most people are still grading in SDR, that’s probably why the default is Rec709. But depending on your NLE, this is likely going to be flipped automatically as you start working in SDR or HDR color space. I’ve done HDR grading in FCP, Resolve and Premiere, and each handled the files differently but ultimately for the same results. The file itself is 10-bit, and has all the dynamic range. There’s no 10-stop clamping because the source file has a Rec709 tag on it. If other cameras let you switch the flag internally, that’s nice, but ultimately useless. If you want a Rec2100 flag out of the camera, shoot in HLG and you’ll get it. And finally to make the point of why standards are important, the blackmagic HyperDecks at one point inadvertently set the flag of all recordings to Rec2020 which really screwed up SDR workflows, because the NLE didn’t know what to do with the Rec2020 flag in an SDR space. They fixed that almost immediately, but it shows the importance of standardizing on a Rec709 flag for Log footage.
It's really strange I haven't heard about this more. It's a actually a huge thing.
it is! But not many cameras support it. One of the LUMIX advantages ☺️
But what about my 1000 dollar atomos to shoot in 5.8 k apple res raw? How can I still still shoot in raw while in open gate?
But what about my 1000 dollar atomos to shoot in 5.8 k apple res raw? How can I still still shoot in raw while in open gate?
there is an open gate mode in RAW at 4:3 as well. It's not quite as high resolution, but it is there.
16:50 That's so so cool!
☺️
I have found a better workaround. Public executions for anyone using 9:16.
ok, boomer
@PhotoJoseph 😂
😉
Nice video, very informative,, thanks. Question, this concept applies to 4k to hd right? so for those with not too much HDD space, you can shot opengate 4k, then crop vertical 1080 HD. Most social media convert 8k, 6k, 4k to 1080HD anyway. Am i right? Wondering if you can do the same with videos from smartphones.
the advantage of so much resolution is you can crop anything out of it, and yes you're right that all the vertical socials are only HD for now.
@PhotoJoseph i see it from the mobile content creator, shot everything opengate 4k then do the crops for vertical 1080HD. I believe iphone requires an app to shot 4:3 4k
Good explanation. Thanks. I hadn’t thought about it that way but makes perfect sense.
Right on! Opening gates, opening eyes 😂
Thank you for sharing your GH6 Open Gate workflow. It is incredibly informative. Your straight forward presentation is paced well and easy to follow. I plan to use open gate acquisition quite extensively because of the flexibility it allows me in making HD deliverables while maintaining a master that can be repurposed and future proofed to create up to a 5K deliverable to streaming services. Like you I also enjoy shooting with my set of Meike Cine style prime lenses and my set of Surui anamorphic primes. The flexibility the GH6 gives content creators of intellectual properties for meeting the demands of a worldwide dynamic changing marketplace is unmatched at it’s price point.
thank you! Sounds like you definitely “get it”. It’s a powerful way to shoot for flexible delivery, for sure!
I hate the new (cell phone) vertical images!
The GH5, the gift that keeps on giving. Thanks for the download!
Yeah I film in open gate too
Same for the Panasonic LX100 I used to have. Had a dedicated switch on the lens to switch between aspect ratio's on the fly. This also supported 4:3 and worked great! The greatest feature is Aspect Bracketing where you can take a single picture and it takes 4 different pictures with all 4 aspect ratios in the camera (3:2, 16:9, 4:3, 1:1).
Too bad it's in LongGOP. All I would be easier.
And require a more powerful processor. It’s all give and take, balancing processing power and expectations
My sony 5 r has this I keep them around if I need a camera I can risk on film set
the NEX-5R? I did not know it shot full frame (APS-C) at native 3:2 at 30p. Is that what you’re saying it does? Cool!
@PhotoJoseph it's a good useful little camera and it has easily upscalable footage using topaz labs it's not full frame but you can use the 3:2 it has an anamorphic mode the video quality is not the highest bit rate but using a modestly good lens gives Sharp yet not over sharpened footage and you can also use the hack to get a hundred megabits a second 1080p but thats still not great but it's better than it's native 24 megabits and it has an option for either 60 FPS or 24 FPS still not the best but with topaz Labs upscaling the footage to 4K it looks great and fits in mostly with all my other cameras and for the $50 you can pick it up for it's basically a throwaway camera
@PhotoJoseph there is a scammer in the chat
I’ve seen and blocked. Hopefully I got them all but if you see more please report them. Thank you.
@PhotoJoseph okay I will thank you
This is a fantastic video. Really well built and informative. Good Job man c:
Thank you!
My GH5 opengate is awesome. The only drawback if you can call it is the IS is not quite as effective.
+Marc Hill right, that makes sense as you’re using more of the sensor for capture; not as much wiggle room for IS.
I'm just now seeing this. Fantastic video. You obviously put a lot of time into this one and it shows. Thank you.
Just finished the video. That smart reframe is amazing. I still prefer horizontal video but between resolve and the open gate sensor that would take a lot of the pain points out of shooting for different aspect ratios. Do you ever find yourself having a tendency to shoot tighter than you need to just out of habit? You probably have better instincts for shooting/cropping with your photography background.
Hey buddy! Thanks for watching! The open gate and smart reframe certainly does make things easier. You still want to shoot with the final aspect ratios in mind for sure. As to your question; I do my final framing in camera. It’s really rare that I tighten up a shot in post, and even more rare that I wish I’d shot wider. But yeah, I’ve been looking through a lens for 40 years, so that probably has something to do with it!
This actually makes so much sense. I've always wanted my Sony cameras to record videos with the full 3:2 sensor size.
Time to upgrade to LUMIX!
So this is what GoPro has done since the beginning- actually they have more modes where they use the rest of the sensor creatively- a shame that other companies don‘t use more of these options
It is a lot harder on bigger sensors, which is why you see it on small sensors more readily.
This is a such epic feature! I should tell my grandma immdiately, and she doesnt bother to rotate her camera anymore😊
Amazing video and great job! 👏
Thank you!
The gate's clean.
@PhotoJoseph No hair in the gate? It's a wrap.
No hairgate here!
@PhotoJoseph In Ye Olde days before digital at the end of each scene the film loader would take the lens off the camera and check for any thin slices of film or "Hairs" that would occasionally be sliced off the edge of the film as it ran through the film guide or "Gate"
On the last scene of each day the most tense moment was waiting those brief seconds to hear "Gate's Clean" or we'd have to shoot the scene again..
Sounds anxious!!
@PhotoJoseph If only
Just put an overlay on your monitor to frame a bit wider
Thanks a lot for these super useful info!
🙏🏻
imagine if sensors were round (like a lens) or 1:1 square. then you could decide your own ratio in post.
Think about the widest/tallest dimensions of a square/rectangle can be in a circle, and you’ll see why sensors aren’t square. Not to say it can’t be done, but that’s why it isn’t done.
My lumix zs100 has this for photo modes
Does your nucleus nano motor make a rumbling noise with your Meike lenses? Mine does and I find it concerning. I have the same lens set.
If it’s not really tight, yes. I find you really need to ensure it’s pressed hard into the lens, and mounted really tightly on the cage/rod.
I dont get it. Its still MFT. Why wouldn't you just get a camera with a larger sensor?
You say “it’s still MFT like that’s a bad thing”. And a bigger sensor doesn't change anything here. In fact, a bigger sensor means 3:2 instead of 4:3 so offers a “less square” aspect ratio. I’m curious, what do you think of the video quality of all the footage in this video, including the main shots of me on the “white gear wall” set?
@PhotoJoseph The video quality is great but it isn’t square. As far as I understood your point, it is about cropping the video, right? But regardless of the aspect ratio, you are limited by 13mm sensor height, whereas e.g. APS-C offers 15.7mm. I like MFT, actually I got a MFT camera myself but I like it for the smaller overall system size not for cropping potential.
It’s not about mm height of the sensor. It’s about aspect ratio (closer to square is better for dual cropping) and resolution (enough resolution vertically and horizontally to crop 16:9 and 9:16 with room to reframe and no upscaling). Have you watched the complete video? I feel like you’re missing the point of discussion here.
How about the G9?
are there other cameras that can do that : o
Very few
Well, you can crop any format out of any format right?
of course; if you have the resolution. Not quite sure what you’re stating here.
@PhotoJoseph While it might be interesting to have some framing abilities in post production. I personally go for most reliable setup. Typically thinks like 6k stress camera, battery and cards and I do live stuff so when it is gone it is gone, no second chance. And recording 6k or even 8k in 4:3 or 1:1 results in >1/3 of file size, card bandwidth and render time directly for the trash bin. Also cropping can result in strange effect due to distortion, lack of corner sharpness and vignetting, For what I do I see no advantage. I do cropping with my lenses not my computer. I even stopped recording 4k, because on my many distribution channels youtube and blueray the higher resolution or bandwidth cannot be noticed by the average audience. Especially if using natural or ambient light...
Understood, however I'd say that if the camera and cards couldn't handle recording at the stated size and bandwidth, then they wouldn't be able to. Panasonic is very conservative in its published capabilities. As long as you have a workflow that works for you, that's all that matters!
for my usage, 4:2:0 and LongGOP makes it a bit useless ...
Thank you for including “for my usage”. Although I’ll point out someone here in the comments uses it for green screen keying, saying the excess resolution
makes up for the loss in color fidelity. Also you can do RAW with the ninja V+ for 4:3 5.8K. I believe it crops slightly but I’m not 100% sure and I don’t have a V+ to test with.
@PhotoJoseph: it`s always about the use case. when using other codec-options that have at least 4:2:2 with 10 Bit and All-I, one will not get back to 4:2:0 ...
@Philipp Peyer I shoot almost exclusively ProRes 422 but there are times where what I want is only in 420. Somehow, I make it work 😉
@PhotoJoseph: me too, prores 422 is really nice, but since BMD introduced BRAW i like that as well.
A lot of codec bandwidth is wasted here.
??
@PhotoJoseph Well 200Mbits is used for the whole open gate 4:3, when you cut out 16:9 frame you cut out 35% of the total bandwidth so are left with only 130Mbit for your 16:9 end product.
Thanks
I wonder what camera used in this vlog? It's focus hunting.
In what scene?
Also: anamorphic lenses work best on open gate mode
That’s what the mode was originally intended for. This is a “byproduct” of that format.
Could you possibly do a quick video of Proxy Files. Could you show the workflow from beginning to end, I'm new to that aspect, thank you, great stuff.
I actually am planning a workflow video on this, centered around the Blackmagic Cloud Store Mini, but that won’t be until September at the earliest.
Whoa, that smart reframe is out of this world, so cool!
So SO cool!!
How did you use a 1 TB CFexpress card when the GH6 can only support a 512 gb CFexpress card?
The spec does say 512 max, but that just means that’s what it’s been tested to. My 1TB works perfectly!
Hi Joseph, Is it me or it seems like you have been quiet for a while. Really great video about Open Gate/Anamorphic mode.
Thanks brother! Busy days, with projects outside of YouTube. And this one took a while! Previous video was probably a month prior, on PTZ.
@PhotoJoseph Hi Brother, sounds great, I finally finish off my feature film in less than 4 weeks!
@Shark WOW. I can’t even imagine the undertaking.
😋
Do Sony Alpha cameras have this feature?
Nope
iPhone will probably adopt this feature in the future, makes more sense since direct upload to tiktok aspect ratio
Do you have to have an anamorphic lenses to make this work?
Not at all! I didnt use a single anamorphic lens in this video. The open gate feature was designed for anamorphic lenses, where you would stretch the width back to a widescreen format. But with regular lenses you don’t distort because the image is true at its native 4:3 ratio, and you gain the benefits explained here!
@PhotoJoseph Awesome to hear that, and thank you for the response.
