Samsung ISOCELL GN2 does 480fps!

The hegemony of phone sensors has been the purview of Sony with their Exmor sensors for many years but now Samsung has started making inroads in the space with their ISOCELL chips. The latest is currently mass-produced and shipping in handsets already which is not a paper launch, but a real thing. The chip is capable of massive low light improvement compared to other sensors because it is essentially a near 1″ sensor with 1/1.12-inch measurements. This is close to what Sony RX cameras use as a main sensor, and a first for a phone.

As to how they are able to fit this sensor on phones, it is a dance between a protruding camera bump that is a little larger than usual and also a lens system that creates a full imaging circle from a minute distance. The GN2 is capable of recording 480fps in HD 720p, 4k 120fps, 30fps in 12.5MP windowed size and 10fps in 100MP mode which uses a clever algorithm and three RGB exposures to derive a 100MP image from the 50MP source. → Continue Reading Full Post ←

Sony a7s III Slow Motion Samples!

Sony a7s III Slow Motion Samples

Now that the excellent a7s Mark III video recording mirrorless camera has been out for over six months, it is time to revisit the slow motion component and see what quality we can expect from the Sony a7s III Slow Motion Samples. Many have praised the 4k 120fps mode which is heavily detailed, low noise and suffers from only a very small crop factor that is hardly a problem.

We looked at the Full HD 1080p 240fps mode on the camera and it was clear it did not match the 120fps 4k mode as it was not only less detailed but full of aliasing and moire if you looked for it. It was clear the camera was not up to professional standards when in this mode which is to be expected from a full-frame sensor cropping to 1080p. That said, this camera is a powerhouse that easily takes the mantle as Sony’s best mirrorless compact video camera.

Sony a7s III Slow Motion Samples:

Be aware that 120fps in 4k is not only highly detailed and full of dynamic range but it is the best high frame rate this camera has to offer. You can easily use this mode for professional broadcast or film work is shot in good conditions.  The a7s Mark III is the best Sony Alpha line camera for low light performance and it is evident by the samples this translates directly into higher frame rates.

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:

Video Modes: AVC-Intra/AVC-LongG/H.264 Long GOP/H.265/MOV 4:2:2 10-Bit:
4096 x 2160p at 23.98/24/25/29.97/50/59.94 fps (100 to 400 Mb/s)
3840 x 2160p at 23.98/24/25/29.97/50/59.94 fps (100 to 200 Mb/s)

1920 x 1080p at 23.98/24/25/29.97/50/59.94 fps (100 Mb/s)
AVC-Intra/AVC-LongG/H.264 Long GOP/H.265/MP4 4:2:2 10-Bit:
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.

Blackmagic URSA Mini Pro 12k Camera Setup 7 new Frame Rates!

Blackmagic URSA Mini Pro 12k Camera Setup 7

Blackmagic Design has released Camera Setup 7.0 which upgrades the URSA Mini Pro 12k camera in several areas including improved frame rates at different resolutions.  At 12k the maximum frame rate has increased to 75fps from 60fps and at 4k we now have up to 240fps in BRAW format from 220fps on a Super 16mm crop of the sensor. We also get 8k at up to 160fps from a maximum before of 110fps which is improved by leveraging the fast pipeline in the camera and delivering usable frame rates with good multiples.

While the camera is not cheap at $9,995, it is certainly a bargain considering the resolution and frame rates you have access to in BRAW RAW-Like format.  It may be essentially the most powerful camera you can buy today for this price range and available with an F, EF, or PL mount the flexibility is there if needed.  Blackmagic Design are also the owners of DaVinci Resolve and usually bundled it with their cameras. It makes for a hard to beat all in one system for shooting, editing, and postproduction. Dig in for more details…

Blackmagic URSA Mini Pro 12k – Full High Speed Frame Rates After Update:

12K 17:9 full sensor up to 60 fps
12K 2.4:1 up to 75 fps
8K DCI full sensor up to 120 fps
4K DCI full sensor up to 120 fps
8K 2.4:1 and 4K 2.4:1 up to 160 fps

6K Super 16 up to 120 fps

Galaxy S20 Slow Motion Samples Revisited!

Galaxy S20 Slow Motion Samples

Due to reader demand, we are posting new slow motion samples for the Galaxy S20 line.  We see just slight improvements over the Galaxy S10 in terms of detail and color but since the phones are the new flagship for the defacto Android international brand, there is a lot of weight in what it can do when it comes to the video mode.  There is no secret that Samsung has stagnated in slow motion since the Galaxy S8 and the S20 is an evolutionary step with better reproduction and more intelligent capture but not really groundbreaking.

There is no increase in frame rates above 960fps at 720p and the resolution is not even true 720p as it is jagged and stair-stepped in detailed shots. We kind of see it as a 480p mode upsized to 720p.  We do gain a 1 full second record time instead of 0.4sec on the S10 which is a big improvement even when the resolution is still kind of identical.  It would have been great if Samsung could have done a solid and created a true 960fps 1080p Full HD Mode.  We will have to wait for another crack at it on a future phone.

Galaxy S20 Slow Motion Samples Revisited!

Before you start looking at the samples it is important to revisit the S20 line slow motion specs. Below is the breakdown:
Super Slow-mo only supports HD resolution. On Galaxy S20 and S20+ 5G, users can record approximately 1 second of video captured at up to 960 fps with approximately 32 seconds of playback. On Galaxy S20 Ultra 5G, users can record approximately 1 second of video captured at 480 fps and digitally enhance the video to 960 fps with approximately 32 seconds of playback. Playback time can be edited in Super Slow-mo player.

So to break it down:

  • Galaxy S20 5G – 960fps 720p with 1 second recording time.
  • Galaxy S20+ 5G – 960fps 720p with 1 second recording time.
  • Galaxy S20 Ultra 5G – 480fps 720p with 1 second recording time then it can be interpolated to 960fps 720p for 2x the frame rate.

The good news is we gain recording time from the earlier generation of 0.4 seconds to 1 full second or close to it “We will have to see when the phone ships”. That is a lot to like.  There is however no mention of the quality of the video and if it is improved with less pixelation and aliasing.

So if you want better slow motion the Galaxy S20 Ultra 5G top of the line is not for you as the true real highest frame rate is 480fps. The other cheaper models make more sense here. Time for the samples now…

Galaxy S20 Slow Motion will improve 960fps !

Galaxy S20 Slow Motion

The recently announced Galaxy S20 phone line has been making some waves with impressive specs especially related to the camera modules.  As always we are only interested here in the high speed video specs here at HSC “not even the new 8k video spec” and the new phones are an improvement over the S10 and Note 10 lines.  However, it is important to note that not all S20s will share the same slow motion specs and that is what this post is about.

You may think that the S20 Ultra 5G will be the easy choice here but it is hardly as straight forward as that.  The amount of technology packed in the Ultra phone along with four camera modules and one of them at over 100MP means they prioritized photo resolution over video shooting in their sensor selection. The Ultra will not natively support the 960fps spec but default to only 480fps.

Galaxy S20 Slow Motion Specs:

We go directly to Samsung’s take from this information provided in the official website:
Super Slow-mo only supports HD resolution. On Galaxy S20 and S20+ 5G, users can record approximately 1 second of video captured at up to 960 fps with approximately 32 seconds of playback. On Galaxy S20 Ultra 5G, users can record approximately 1 second of video captured at 480 fps and digitally enhance the video to 960 fps with approximately 32 seconds of playback. Playback time can be edited in Super Slow-mo player.

So to break it down:

  • Galaxy S20 5G – 960fps 720p with 1 second recording time.
  • Galaxy S20+ 5G – 960fps 720p with 1 second recording time.
  • Galaxy S20 Ultra 5G 480fps 720p with 1 second recording time then it can be interpolated to 960fps 720p for 2x the frame rate.

The good news is we gain recording time from the earlier generation of 0.4 seconds to 1 full second or close to it “We will have to see when the phone ships”. That is a lot to like.  There is however no mention of the quality of the video and if it is improved with less pixelation and aliasing.

S20 Ultra 5G Samples?

The following samples by MKP Captain are not authenticated by HSC but seem to be real, in any case, do not bank on the quality shown here until more samples are available.

Samsung Galaxy S20 Slow Motion 2 by MKP Captain:

If the videos above are real then we have seen a mild improvement in slow motion quality but remember that this is the Ultra phone on the top which is shooting at 720p 480fps and not at 960fps even when there is interpolation happening, the frames are half made by the processing unit and not captured live.   At HSC we are no fans of interpolation so we can safely avoid the S20 Ultra 5G as a slow motion contender unless you are fine with 480p.

The second video is of the regular S20 which shows no interpolation artifacts but the quality still leaves a lot to be desired. Samsung seems to have added time recording but hardly improved the quality from earlier phones that offered 960p.
