Lumix GH6 will do 120fps 4k & maybe more!

Lumix GH6 Panasonic

Panasonic unveiled in May the GH5 Mark II which is a slight refresh of the venerable m4/3rds GH5 with live streaming, better dynamic range in video, better AF algorithms, and slightly better IS on a very similar body with just a few cosmetic red buttons and rings for refresh purposes.  The slow motion remains at 180fps VFR at 1080p and 60p at 4k on the GH5 II since it is using the same sensor and imaging engine. It is a better overall camera than the original but a mild refresh nonetheless. 

That brings us to the pre-announced GH6 which is an in-development camera that aims to refresh the entire Micro 4/3ds line in Panasonic and aimed at professional video users.  It sports a new sensor, new imaging engine, new body and new technologies yet to be disclosed.  According to rumors, this camera should be able to keep micro 4/3rds alive for another five years delivering an array of video and photo features that will set it apart much like the original GH5 carved a place in camera history. We have also received rumored specs that may or may not pan out regarding frame rates which we find somewhat credible.  → Continue Reading Full Post ←

Panasonic Lumix BGH1 Slow Motion at 240fps is good!

Panasonic Lumix BGH1 Slow Motion

The Panasonic Lumix BGH1 is a strange camera if you are used to DSLR or Mirrorless camera body styles. It is tiny and full of connections with no screen unless you provide one via a computer that is tethered or an HDMI field monitor.  It uses the same dual ISO sensor found on the Panasonic Lumix GH5s which is a very good low light camera in a Micro 4/3ds package.  The BGH1 has a better internal recording set of options than the GH5s but it is more intended as a tethered studio solution with the addition of Genlock synch and SDI out.

The camera also has VFR or a Variable frame rate mode which is identical to the Lumix GH5s as it records from 1fps to 240fps in Full HD 1080p and delivers pretty good performance up to 200fps then lowers the quality along with providing a small added crop to the image at 225fps and 240fps. It is still not as sharp as regular 1080p video and the codec is saved at a lower bit rate but having 240fps as an option is great.

Panasonic LUMIX BGH1 Video Specs:

3840 x 2160p at 23.98/25/29.97/50/59.94 fps (72 to 100 Mb/s)
AVC-Intra/AVC-LongG/H.264/H.264 Long GOP/H.265/MP4 4:2:0 8-Bit:
3840 x 2160p at 23.98/25/29.97 fps (100 Mb/s)
1920 x 1080p at 23.98/25/29.97/50/59.94 fps (24 to 28 Mb/s)VFR Mode 1-240fps Full HD 1080p (24 to 28 Mb/s) 

As you can see, the camera is capable of recording up to 60fps in 10 bit 4:2:2 internally which is better than other m4/3 lumix cameras that top out at 4:2:0 color space in this mode.

Of note is that the VFR Panasonic Lumix BGH1 Slow Motion mode is limited in bit rate from 24Mbits/sec to 28Mbits/sec which is passable but hardly ideal since the image is more compressed.  The quality of the VFR should be identical to the GH5s and the sample below by the great youtube reviewer Richard Wong you can see the softness associated with 240p in VFR.  We are told that up to 200fps the image looks a bit better and there is no crop associated with it.

Pretty In-Depth Panasonic Lumix BGH1 by Richard Wong: 

As you can see in the excellent in-depth review above, the camera has Auto Focus that is pretty similar to the other cameras in the Lumix line and suffers from the same pulsating qualities of the DfD Depth from Defocus algorithm used by Panasonic. We are no fans of it for video even when it has improved a lot. For AF to work reliably you need to have dual Pixels in the sensor with Phase and contrast-detection like those on systems from Canon or Sony.

The camera is very small and it is ideal for drones that can carry the 545g of the body plus a lens.  At $1,997.99 at Adorama Camera it is about the same price as a Panasonic S5 which is a full-frame camera that delivers even better performance in low light and has a photo mode and screen.  The S5 in our view is a better overall camera for the majority of people but the BGH1 is geared to a different market altogether.

You could build a studio with them as they have Genlock timecode sync and SDI out which is what you want for tethering many of these cameras together. The uses for a camera like this are plenty considering its great low light performance and beautiful image with 13 stops of Dynamic Range when Shooting V-Log L.

Panasonic EVA1 Firmware Update 2.02 Frame Rate Improvements!

Panasonic EVA1 Firmware 2.02

The new v2.02 firmware update for the Panasonic EVA1 includes improved bit rates at a variety of frame rates like:    2k- 422-Intra Frame Recording 200M/100M Max 120fps (equivalent to 400Mbps) Which may improve slow-motion quality considerably by allowing more data to be saved instead of scrapped.

For digital recorder owners, there is a lot to be excited about as the camera will now output RAW data at: 5.7K/30p Full sensor, 4K/60p Crop ,  2K/240p Sensor Crop.   Since the 240fps mode saved internally exhibited very severe aliasing, moire and line skipping; the fact that RAW is now a possibility should bring the camera’s capabilities up a notch and deliver excellent slow-motion quality. We hope to have some samples of the RAW recording on the EVA1 in a  future update.

GH5s Slow Motion Quality is Inferior to GH5!

GH5s Slow Motion

As expected based on early comments of the slow motion mode on the GH5s, the camera has pronounced aliasing “seen in this video by Max Yuryev” and softness the higher the frame rate goes. Even at 120p it is less detailed than the standard GH5.  It may be a function of supersampling in the higher megapixel  20MP GH5 vs the 10.2MP GH5s which is creating the new artifacts.

While the GH5s can shoot up to 192fps without cropping the sensor, anything above that up to 240fps it has a slight sensor crop which further decreases quality.  While the VFR mode on the camera is better than most cameras in the price range that attempt the feat, it is of note that the quality instead of increasing or remaining the same as the sister model takes a hit which may kill it as an option for slow motion needs.  We still believe the standard GH5 is the best Lumix option even when compared to the G9 in VFR mode.

GH5S Review – Shocking Lowlight for a Micro 43 by Max Yuryev:

In the video above by Max Yuryev you can see at playback position 5:30 the slow motion test between the cameras. Excellent test by Max and the subject matter clearly shows what the camera loses in detail retention.

All is not a loss as the 4k footage coming from the GH5s is as detailed as the GH5 with excellent quality and no aliasing and moire problems. The new camera is a low light beast and it shows it’s prowess in the rest of the test. You are buying this camera for the high ISO performance and not the slow-motion necessarily and gladly to see the new camera performs beautifully compared to most any camera out there.

Panasonic GH5s Boosts High ISO dumps IBIS!

Panasonic GH5s

So the rumors proved to be accurate on the GH5s and now we have a low light version of the GH5 that can shoot cleanly up to ISO 12,800 with up to 100k ISO and by then a much noisier picture. It is claimed by Panasonic that there was a 1.5 stop improvement in noise performance.  Judging by the initial video samples it is clear that the new 10.28MP sensor along with dual native ISO circuitry for each photosite “one at ISO 400” and “one at ISO 2400” make a huge performance leap if low light is desired in a m43 camera.

All is not rosy in Lumix land however as the camera now lacks IBIS or In Built Image Stabilization on the sensor which was a main selling point of both the GH5 and the G9.  Panasonic claims that it was a decision made to cater to filmmakers that need no wobble or vibrations in a shot that can be produced when the stabilizer fails. But why not just add an On-Off switch? 1080p 240fps is also included in the camera but as initial samples show it reduces quality substantially.

Panasonic GH5S Video Hands-On – Highlights of the New Camera by cinema5D:

GH5s VFR Slow Motion performance?

As you can see from the excellent first look video above by Cinema 5D the video quality in low light is very much improved from the GH5 and G9. However, the slow motion at 240fps is full of resolution loss, jaggies, and moire which is to be expected as information is being thrown out to cope with the data rate.  This begs the question so what does it look like up to 190fps which is the limit before the VFR mode starts to crop the image. We estimate that it may actually do better than the GH5 and G9 at 190fps and below in which those two other cameras suffer resolution loss as well.  It will be interesting to see if the 180-190fps GH5s is excellent quality. There might be something to cheer here for high frame rate enthusiasts.

Lumix GH5 vs G9 High Speed VFR Mode Capped!

Lumix GH5 vs G9 High Speed

As suspected in a previous article from HSC the Panasonic G9 bitrate for VFR or high frame rate mode is much lower than on the GH5. The Manual has been released for the G9 showing this lower spec.  It is of note that the codec used on both cameras is very efficient which lends itself to good quality even at 20mbps.  However, for those that want to prioritize fine detail and the utmost sharpness, the GH5 will, in the end, be the better option for slow motion.

There is also the upcoming announcement rumor of the GH5s Lumix camera now with leaked images here with 240fps at full HD using a completely new sensor which may be able to improve of the GH5 slow-motion quality which in our analysis was lacking when using 150fps and 180fps on the regular GH5. Aliasing and moire were evident in footage which is not present in the 120fps mode.  Considering the GH5s might be recycling the same image processing engine but with a new sensor, we may still see some artifacts.

Lumix GH5 vs G9 High Speed VFR From PDF Manuals:

Lumix GH5 Manual Page Showing High Frame Rate Bit Rates up to 100Mbps depending on Codec / Low of 24Mbps:

Lumix G9 Manual Page Showing High Frame Rate Bit Rates Max 20mbps at 1080p:

You can download the Panasonic G9 and GH5 Manuals here for comparison:  http://www.panasonic.eu/downloads/en_GB/popup.html

Is this a big deal?

For the majority of users, the 20mbps on the G9 vs 24 -100mbps on the GH5 for the slow motion VFR mode will be of no consequence. Detail will be lost and color correction/grading will be less forgiving but for anything broadcasted over the web at 1080p, you may see almost no difference.  Still, we think the GH5 is the superior video product as the camera is more geared to the footage acquisition camp since the start.  G9 is a photographers camera that does excellent video as a side effect of Lumix GH pedigree, probably the best stills performance from a Lumix camera yet.

We are eager to see next Monday, January 8th, 2018 the rumored announcement of the Panasonic GH5s which should be important going forward as 240fps continuous shooting might be possible for the first time in a camera of this kind.  -HSC
