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+!
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.
Great video, as always! One correction: GH5 II shot anamorphic 6k, not 5k.
Thank you for such videos. My question is regarding the highest quality you can squeeze out of the GH6.
Without worrying about space and file size, what do you think is the best way to benefit and get the highest quality out of the sensor? My end goal would be 16:9 aspect ratio.

1st option I have is
Prores 5.7k in 30fps

2nd opinion is
Prores C4K 60 which gives you about 800mbps

3rd option is shooting in open gate 5.7K 30fps like you are encouraging and then squeeze it into 16:9 ration. Only thing with this is you can only shoot open gate in Mov or mp3, no options for open gate in prores internally. Also, knowing I only get 4.2.0 HQ in open gate vs 4.2.2 HQ without open gate.

Which brings me to my question. Without worrying about codec, formats and file size, which one of the 3 different options do you think will give me the best video quality and best color?
I shoot in Vlog and, I do not intend to do slow motions really. I am just looking for the best video color. What's your recommendation? Just want the best gh6 can give you recording internally.

Thank you so much
@Trail Ambience ProRes
@PhotoJoseph they are actually both in Prores. On is just 4k with more frames 60fps. And the other is 5.7k but with less frames 30fps. But both are in prores.

With 4k 60fps I have more frames every second which might mean better Images maybe?

Or record 5.7K 30fps and compress it to 4k in post with hope it will get me a better image maybe?

Sorry I'm asking alot 🙂
@Trail Ambience ah, right. Look at it this way. Think about the words. XX mbps means megabit PER SECOND. 60 fps vs 30 fps is the same mbps. What does that tell you?
@PhotoJoseph that means if mbps is the same, then 5.7k 30fps is going to be better than C4K 60fps, right?
@Trail Ambience yes — although to be 100% honest I may be misleading you. Ok work with me here… 30p vs 60p is half the frame count so double the data per frame. However I’m realizing that the 5.7k image is 17.3 million pixels while the C4K image is 8.8M. That’s over 2x the pixels so it becomes really close. Personally I’d shoot 5.7 over C4K if you don’t need the 60p, because I’d rather have the room to punch in. I don’t have the camera in front of me, but do some tests and check the actual data rate in the captured files. (Make sure you test the same image; ProRes is a variable codec and will change depending on the content). So shoot something like a waterfall or waving trees where you have lots of motion. At the end of the day though I think it’d be virtually impossible to tell the difference, so again, the 5.7K image gives you the option to punch in which is invaluable to me!
I just shoot and watch 4:3... Even my DVDs are Fullscreen 🤣🤣🤣
Haha it’s a way!
Everybody eat Rendang ❤
Well, thanks. I have s5 so i shoot at 3:2 6k photo mode that shoots at a resolution that is 5k x 3k ish. I adjust shutter speed to 100 or less to get a video blurr.
But i render in the same aspect ratio as i am bored of 16x9 , plus the fact thst i have to loose so much area.
It works for me.
This is the guy John wick would go to if he was a photographer.
Haha I love it
Kind of funny how 4:3 is a “feature” these days but 16:9 was a “feature” 20 years ago.
Haha totally. Slightly higher resolution now though 😉
Excellent video. Is this available on the G9?
That's just clean! Got the gh6 in April (super dope camera). Never considered the reason to shoot open gate. This is a game changer brother!
Awesome, thanks! Yeah it’s definitely a cool feature
Amazing feature and a very informative and excellently made video (my only regret is that I didn't see your video sooner). I have both GH6 and GH5II. I see you use a Desview R6 monitor, but you only touched that briefly. I can't find from their products if any of their models will show the 4:3 aspect ratio, or just the 16:9 crop. I'm looking for a monitor that will show the full frame of the open gate 4:3. Any thoughts/brands/experiences?
Any monitor should work. The camera is outputting video to match the capabilities of the monitor (HD or UHD) and will pillarbox the output so you’re getting a 4:3 image.
@PhotoJoseph Thanks. This was most helpful as this open a world of possibilities. Learning new things for my Panasonics everyday. Just got a Tilta Float arm, and your other SmallRig review was also very helpful. Monitor next. Thanks one more.
@Arnfinn Nilsen awesome! You’re gonna love my next video 😉
There's no reason Sony can't release a firmware update that would provide open gate for the Sony A7S3.... No reason. Hardware can absolutely handle the processing. Even if they limited it to HDMI raw output only... With no internal write. It's annoying as hell they don't do this.
Although I still don't understand what this does on my gh5, but all I want is good low light performance. U seem like u know alot with all those lenses and cameras so could u tell me like the best low light lens?
If I’m not mistaken, doesn’t the G9 shoot open gate in 6k photo mode? You can choose 4:3 or 3:4, but it’s at 5.1k higher than the GH5.

Am I missing something here?

Great video BTW☺️
Hey there thanks for this video it is really insightful, appreciate it! I have a question as a GH5m2 owner. If I shoot open gate in 4k and crop in post am I losing quality as opposed to just shooting in 4k with the regular 16:9 aspect ratio? Does Panasonic do any enhancing when cropping in 16:9 that is missed when going open gate? Or am I just doing in post what the GH5m2 does for me when selecting a 16:9 aspect ratio. Thanks!
And the BGH1
Nice set up ill bet costs more than my daily driver lol ill be happy with a old small aps-c 18m prickles camera sony or me recording in 4k+ for all but large nature shots is unnecessary just a head ache .so 1080p would be my go to
Sounds like you have a solution!
@PhotoJoseph i do like the way you went into all that about camera stuff its like way on the upper end but just like in audio, electronics or circuity it`s needed to under stand better the basics.may be i am just a bit of a crazy nerd .but.good show God bless
Hehe it’s fun to be a crazy nerd ☺️
Can't you talk any faster?
I could, but then even more people would leave snarky comments
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.
