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 ←

Oppo Find X3 Pro brings microscopy to phones!

Oppo Find X3 Pro

There is always an outlier when it comes to phone innovation and we have to give it to Oppo in 2021 as it seems to have created a phone that really delivers features that seemed impossible just months ago.  The Oppo Find X3 Pro can deliver the usual 4k 30p and 60p video and up to 720p 480fps slow motion along with the common standard of 240p at 1080p.  Where the phone jumps ahead of the pack is the inclusion of a real microscopy camera module that has a ring light to boot.

The Microscope camera can deliver a mind-altering 60x microscopy range magnification that looks so good that you might think it was taken with a professional clinical microscope.   It will not be enough to show blood cells that usually require over 100x to be appreciated but it delivers detail on small insects, fibers, textures, and electronics that previously required a complicated camera setup attached to a multi-lens instrument. → 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:

Multiply Your Video Frame Rate with Dain-App !

Multiply Your Video Frame Rate

We got over 20 messages with essentially the same video sample in our inbox this week. They all touted the new interpolation from the DAIN experimental App or (Depth Aware Video Interpolation App)  which now analyses footage with a Neural network AI algorithm that crunches motion vectors and even what seemed impossible before “Object Occlusion” to generate higher frame rates from lower fps sources.  The technology is pretty fascinating and should be further improved by more training and samples over the coming years.

For stop motion animators, this is a complete game-changer as now you could animate with as little as 8fps and then interpolate to 30fps or 60fps with very little in the way of tearing and artifacting as long as the footage is well lit and objects clearly defined.  To make matters more interesting, it also analyses footage with shallow depth of field yielding impressive results.

Multiply Your Video Frame Rate with Interpolation or the “I” Word for Slow Motion Enthusiasts:

We visited the Interpolation topic in the past on our Fake Slow Motion article and concluded that then, the quality of interpolation while good was far from usable and you really could not compromise real high fps footage from interpolated versions except in very simple cases.

Now with DAIN technology, we have no choice but to re-visit the cases and analyze what it is capable of.  We looked at a few dozen examples and it is clear the technology has progressed forward so much that now stop motion animation, 2D Cell-based cartoon animation, and even 3D animated sequences rendered at 30p can easily be turned in higher fps increments yielding impressive and in some cases miraculous results.

We would like you to first watch the video below to understand what a depth map is and how the software in DAIN can create frames from nothing that look just like real ones.  A depth map will generate an approximated view of the world in a Lidar-Like vision representation to figure out to the best of the AI estimation where objects are in a scene according to their location close or far to the camera.

Depth-Aware Video Frame Interpolation by Wenbo Bao:

Even at 48fps from  12fps source, it is clear the technology in DAIN can yield impressive results even with heavy organic detail in the background including foliage. The software does an admirable job of estimating the relative position of objects in the video scenes.

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…

Fighter Jets captured in 4K Slow Motion with 600mm Lens!

The great slow motion YouTube channel Warped Perception has created what will probably be the best new high-speed video of the decade.  By marrying what looks to be a Vision Research Phantom Flex 4k with a Canon 600mm F4 L lens for a killer and expensive combination, they have been able to show things rarely seen in regular footage like stress on the fuselage and air dynamics impacting the aircraft as they cross paths.  Congratulations to WP for creating such an awe-inspiring video!
