Alice Camera and why the Future is Bright!

Alice Camera

The Alice Camera, launched to great success this month has to be the most hopeful product for the future of cameras that we have seen lately. It marries the Sony IMX294, a 10.7 megapixel 4/3 sensor with a custom chipset including the Edge TPU chip from Google for AI and an FPGA for calculations.  The result is a camera body with the same sensor as the GH5s which is a killer low light camera capable of excellent 4k footage and images with super low noise.

Then the camera back is attached to your Android or Apple smartphone to gain an interface and software to control it. The camera is capable of using the latest research for computational photography including HDR with multiple exposures merging, tracking, night mode, averaging of pixels, and as an open-source architecture, you can add features by other coders or your own to make the camera increase the feature set. → Continue Reading Full Post ←

Slow Motion on DJI Pocket 2 & Fuji X-S10 Offers 240fps!

Slow Motion on DJI Pocket 2 & Fuji X-S10

Two very different new cameras were released this week that are able to shoot in 240fps Full HD 1080p. One is the Fujifilm X-S10 which is an all-rounder mirrorless camera with 6 stop IBIS and cinema video profiles for $999 body only, the other is the sequel to the very well received DJI Osmo Pocket now named DJI Pocket 2 dropping the OSMO part of the name & starting at $349 in its most basic form. Slow Motion on DJI Pocket 2 & Fuji X-S10 is close on both.

Both cameras are able to do 120fps as well but the interest peaks at 240p where the speed makes things moving slower more detailed, especially people as at that speed lifeforms moving relatively slow are excellent subjects. For faster animals like birds or flying insects, you need many more frames per second, usually in the 700+ range to create a good enough effect.

Slow Motion on DJI Pocket 2 & Fuji X-S10 – Two cameras that are very different but can shoot the same fps!

Fuji X-S10 Video Modes:

Video Recording Modes H.264/MOV 4:2:0 8-Bit
DCI 4K (4096 x 2160) at 23.976p/24.00p/25p/29.97p [100 to 200 Mb/s]
UHD 4K (3840 x 2160) at 23.976p/24.00p/25p/29.97p [100 to 200 Mb/s]
DCI 2K (2048 x 1080) at 23.976p/24.00p/25p/29.97p/50p/59.94p [50 to 200 Mb/s]
Full HD (1920 x 1080) at 23.976p/24.00p/25p/29.97p/50p/59.94p/100p/119.88p/200p/239.76p [50 to 200 Mb/s]

So starting with the Fuji X-S10 we cans ee that it has a plethora of video recording modes with the absence of the now much coveted 4k 60p which is not here in any form. We do have a 2k cinema mode with 60p which is an ok consolation prize but in a world of 4k it seems they could have added that 4k 60p just to be competitive.

We get 100fps and 200fps at 1080p in PAL format and 120fps and 240fps in NTSC mode. As far as we know every camera can be switched with a single menu to be able to use either of the two systems.

The great news here is that the slow motion modes at 1080p offer up to 200Mb/s in the codec which is pretty remarkable considering not many cameras pass 50Mb/sec in these modes.

The bad news is that the slow motion seems a bit mushy and pixelated which is an unwelcome sight. We found a short video showing this mode at the video below at 8:16:

Fujifilm X-S10 Hands-on Review by DPReview TV:

While we need more samples for full confirmation it does look more like a 720p up-rez than true 1080p, which is common in cameras that shoot these kinds of frame rates and are not dedicated slow motion cameras.  Even Jordan the reviewer above states that the quality of the footage at 240p is nothing to brag about and it is pretty low quality. Kind of sad considering the maximum bitrate of 200Mbps at 1080p.

The Fuji X-S10 is an interesting camera that can do a lot of things right, it is great that it offers very good frame rates as options and we will re-visit this camera in the future when more samples are available. If you are a Fuji system enthusiast, we actually think the new X-S10 is probably the best bargain for a powerful camera in Fuji Land and you really cannot go wrong if you want to shoot video with its great stabilization and flip out Vari-Angle screen.

DJI Pocket 2 Video Modes:

Slow Motion:

  • 240 fps Recorded at 1920 x 1080p
  • 120 fps Recorded at 1920 x 1080p
Video Rec Formats 3840 x 2160p at 24/25/30/48/50/60 fps (100 Mb/s MP4 via H.264/AVC, MPEG-4)
2720 x 1530p at 24/25/30/48/50/60 fps (100 Mb/s H.264/AVC, MPEG-4)
1920 x 1080p at 24/25/30/48/60 fps (100 Mb/s MP4 via H.264/AVC, MPEG-4)

The DJI Pocket 2 is a very impressive device. On the one hand, it has a larger sensor than its predecessor, one rivaling the old P&S prosumer cameras like the Canon G series back in the last decade.  The sensor is  1/1.7″ 64 Megapixels which allows for 8x true zoom crop on the image if needed.

On the other hand, it has a gimbal that is the main selling point that this camera has going for it. A true stabilized system akin to those on DJI drones but on your pocket/hand.  The performance of stabilization is remarkable and the addition of an optional lavalier mic. option with a clip-on module makes it ideal for Vloggers to shoot on a minute and cheap all in one package.

The slow motion modes at 120fps and 240fps are there and easily accessible which is great news since the original Pocket maxed out at 120fps with a 200fps hack that was not really usable.

We found a couple of great samples of slow motion 120p and 240p in the video review below at 9min 45seconds run time:

Panasonic Lumix DC-G100 120fps Slowmo Full HD and why to avoid it!

Panasonic Lumix DC-G100 120fps Slowmo

The new trend this year is the selfie mirrorless camera being bundled so that Youtube and other social media Vloggers get a camera that can easily capture what they need with little fuzz. It is no secret that camera sales are in free fall and companies will try to market anything and everything to get some sales. Such is the case with the Panasonic Lumix G100. It has a very nice microphone, a diminutive body, a terrific bright day screen, and a very portable and good enough image from a micro 4/3 sensor.

So why all this negativity? Well for a camera that wants to compete with the smaller 1″ sensor but better overall featured Sony ZV-1 with excellent dual pixel tracking AF; the G100 is limited in a variety of ways. The 5x stabilization will only work in 1080p and be only electronic in 4k.  4k itself only lasts 10 minutes which is very constrained for 2020, maybe for 2016 as a spec but not 4 years later. Dig in for more info!

Panasonic Lumix DC-G100 Main specs:

  • 20.3MP Digital Live MOS Sensor  m4/3
  • 5184 x 3888 maximum resolution
  • UHD 4K30p Video, Pre-Installed V-Log L (10min limit)
  • 5-Axis Hybrid Image Stabilization (1080p Only)
  • OZO Audio with Subject Tracking
  • ISO 200 to 25600 (Extended: 100 to 25600)
  • Video Modes: MP4 4:2:0 8-Bit
  • UHD 4K (3840 x 2160) at 23.976p/29.97p (10min)
  • Full HD (1920 x 1080) at 29.97p/59.94p
  • Slow Motion 120fps Full HD Mode-
  • 12 to 32mm Lens kit included
  • MSRP: $747.99 with lens and tripod included

For a camera and lens combo under $750 USD it may seem like a pretty good package but when you dig in the details it becomes apparent that you are getting a subpar kit that could have been so much better.

What about Slow Motion?

The video below by Gordon Laing shows a sample of the slow motion on the camera that is very good and will give you a good indication of the per-pixel quality. It is also a very complete review with AF tests and the audio modes.

Panasonic Lumix G100 review vs ZV1 M50 G90 G95 by Gordon Laing:

The full HD 120fps looks to be on par with other Lumix cameras which is not bad but it is also way below others in their line of cameras like 180fps and 240fps which is not even a choice here.

As a slow motion camera, it is competitive with other 120fps cameras in full HD but not much else. We cannot recommend it over other options like the Sony RX series that can do 240fps in near full HD (See Here) with pretty good results.

Other things:

The stabilization which is essential for blogging is limited in the 5 axis mode to 1080p which is ridiculous, you get electronic image shift stabilization for 4k and a 10-minute recording limit on that mode which is very much a non-starter for vloggers.

Ozo audio in the video above is really the most interesting feature of this camera and something we hope to see in the Lumix line from now on. The omnidirectional microphones allow the camera to estimate the location of the person speaking and link the face detection autofocus algorithm so it stays sharp during recording even when you move out of the frame and back in.

The AF technology used is DFD or Depth from Defocus which is used in the Lumix line of cameras and while excellent for still images it still can’t compete directly with dual pixel AF from other brands that use contrast and Phase detection along with object and animal/people tracking to be very consistent in the video modes. DFD has a hit and miss that is hated by many and a clear let down by today’s AF standards, especially for Vlogging.

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…

DJI Mavic Air 2 has a 240fps 1080p mode that you won’t use!

DJI Mavic Air 2

DJI has unveiled the Mavic Air 2 consumer drone with incredible specs and a fit and finish that rivals their more expensive lineup. We have been waiting for a successor to the original Mavic Air to see where the platform was taking high frame rates but while we now have a 240fps 1080p mode, it hardly what we would call usable for production.  There is a softness and compression that while they look ok for amateur and some Youtube videos it fails for professionals that need that quality output.

There is a lot to like here like the 48MP sensor with 8k hyperlapse and stills mode with RAW along with a better than most other drones 4k UHD mode at 60fps with 120Mbps codec.  It is really a steal if you were waiting for a drone that can do it all and not break your budget.  You get many high-end features on a minute package that while a little big compared to mini drones, it is really small compared to the full-sized Mavic line.

DJI Mavic Air 2 Main Specs:

Sensor 1/2″ CMOS
Effective Pixels 48 MP
Focal Length 24mm (35mm Equivalent)
Lens Field of View 84°
Aperture f/2.8
Minimum Focusing Distance 3.3′ / 1.0 m
Photo ISO Range 100 to 3200 (Auto)
100 to 6400 (Manual)
Video ISO Range 100 to 6400
Photo Resolution 4:3: 8000 x 6000
Photo Format JPEG, DNG
Video Formats 3840 x 2160p at 24/25/30/48/50/60 fps (MP4/MOV via H.264/AVC, H.265/HEVC, MPEG-4)
2688 x 1512p at 24/25/30/48/50/60 fps (MP4/MOV via H.264/AVC, H.265/HEVC, MPEG-4)

DJI Mavic Air 2 REVIEW & First Look – 4K 60p, 1080p 240fps by cinema5D:

If you look at the excellent video above by Cinema 5D and Nino Leitner, it tells you all you need to know about the features of this new Mavic drone for a first look.  He even goes in and shoots a sample of 1080p at 240fps which in our view is a godsend to see because many manufacturers avoid sharing footage from these high frame rate modes.

We can clearly see the video quality in the 1080p 240fps mode is soft and compression obliterates fine detail like that of the grass and girl’s hair.  There is really no point in getting this drone for its slow motion capabilities in Full HD.

That said, this new drone is probably the most exciting release for portability and 4k 60p users that lends itself well for less jittery pan motion and for slowing down overhead views.  It really is hard to justify a larger more capable drone for most video enthusiasts considering how much of their more expensive counterparts is here.

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 Ultra Slow Motion by MKP Captain:

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.
