Canon New Cinema Camera Will do 240fps in 4k!

Canon it seems is thinking 3 steps ahead of everyone else when it comes to pro 8k video.  After being left behind in the adoption of 4k and playing catch up to the format, they seem intent on making their cameras the new 8k default option with specs that seem out of a dreamer’s wish list.  Be warned that these cameras will probably start at $10k USD and go up from there. The low end should be about 10k to $15k for the C300s at the low end, and the high end a $30k price tag for a C700DR.  

The most impressive of the new rumored cameras is the Canon EOS C700DR (DR Stands for Dynamic Range) which will be capable of recording 4k not just at 120fps but a class-leading 240fps with excellent quality. It also hints at a 180fps mode that will have expanded dynamic range if needed.   It is interesting that 1080p as a slow motion mode is not even considered here but these cameras are geared to a specific market and that is digital cinema which needs much more resolution nowadays than what even 2k can deliver, much less 1080p.  → Continue Reading Full Post ←

Sony A1 Slow Motion has 8x Mode!

Sony A1 Slow Motion

Just in time for the Japanese Olympics if they ever take place, Sony has released the Sony Alpha 1 or A1 for short which is probably the most powerful mirrorless camera ever produced.  Customary for Japanese camera manufacturers in Olimpic years, the likes of Canon and Nikon have released their professional flagship products like the  1DX and D6 which are still SLR mirrored products that have the highest possible Autofocus features for a camera of that type as well as speed and dependability.

Sony has had some inroads in that space with the Sony a9 series but they were missing a higher megapixel count version that could really differentiate it from the pack and the A1 seems to be just that kind of product. By shooting 8k video at 24,25 and 30p it becomes future-proof for the next decade as far as resolution goes and by taking 30 images per second in stills mode at the full 50MP resolution with AF Tracking, it is one blinding fast beast.  The fact that it also shoots 120fps 4k and 240fps Full HD doesn’t hurt it either.

The Sony A1 is probably the fastest mass production professional hybrid camera ever made. The speed required for 50 megapixels at 30fps means that it is processing and saving in RAW format or RAW+JPG to CF Express Cards  at 1.5 Billion Pixels/Second and all of this while using the 120Hz continuous intelligent Auto Focus for people and animals.

We have confirmed that the camera has a 21 Megapixel crop factor in APS-C size for stills and possibly video which probably means that all the higher 1080p frame rates are possibly extracted from the crop area of the sensor and not from the full 50MP area.

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:

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 S5 Slow Motion 180fps is Low Res!

Panasonic S5 Slow Motion

Now that Panasonic has officially announced the Lumix S5 Full frame camera which we saw as a direct replacement for the GH5 line even when now it seems a GH6 may be in the cards for a future release, it is now time to examine the slow motion modes on the camera to see if they stand a chance at becoming a feature which will be a seller for the new device or just one more feature.

When the GH5 was announced about 3 years ago it came with a 180fps 1080p mode that was better than many camera’s 120fps modes and quickly became our favorite Lumix camera for slow motion as we noticed how the quality of the 240fps mode on the GH5s low light geared camera was heavily inferior in resolution. The GH5 really became the best value along with the G9 for 180fps slow-mo modes in Full HD.

Panasonic Lumix S5 Main Features:

  • 24.2MP Full-Frame CMOS Sensor
  • UHD 4K60 Video,10-Bit Internal Recording
  • 120p, 150p and 180p Full HD Modes*
  • Slow Motion AF Tracking up to 150fps in Full HD!
  • V-Log, HDR, and Dual Native ISO
  • 2.36m-Dot 0.74x-Magnification OLED LVF
  • 3.0″ 1.84m-Dot Free-Angle Touchscreen
  • Contrast-Detect 225-Area DFD AF System
  • 5-Axis Sensor-Shift Image Stabilization
  • ISO 100-51200, Up to 7 fps Shooting
  • 96MP High-Res Mode, Dual SD Card Slots
  • MSRP: $1,997.99  Body Only or $2,297.99 with 20-60mm Kit lens!
  • Pre-order includes a Free Sigma 45mm f2.8 Lens Via Mail-In Rebate

First the Good:

The 24MP sensor is excellent in low light, it will perform extremely well compared to Micro 4/3ds or APS-C cameras but it will not beat the low light king of cameras the Sony a7s Mark II or III.

The camera can shoot 10-bit internal up to 60fps but it will have an S35 crop at the 60fps 4k mode.  The sensor stabilization is not the best out there but it is quite got at up to 6.5 stops with sensor+lens correction.

If you pre-order the camera you get a free Sigma 45mm f2.8 Lens via mail-in rebate which seems either overly generous or somewhat suspect of fear of people jumping ship to other systems.  We feel this is a pretty good deal especially if you also get the kit lens as that one is over $300 USD discounted if you order it with the camera.

From the samples, we have seen the quality in stills and video is as good as the S1 and S1H with very impressive color characteristics that are as close to the Canon color range as we have seen.  Panasonic has done an excellent job with their color science since the GH5 and it shows how good it has become here.

The Bad:

We get the DfD Autofocus system with no Phase detection pixels which in our view are the only way to go for reliable video AF.  In the early tests, it seems to do quite well compared to previous Panasonic Efforts and most of the pulsing is gone in people tracking scenes.  However, the really depressing thing is that the reliability is not a 100% some would call it 80% or even less which means you simply cannot rely on it for mission-critical footage.

If your camera can only have in focus 8 out of 10 shots then you cannot rely on the video tracking AF for paid work.  Most footage is recorded with the expectation that focus can be controlled, if it fails then you lose time in production and worse yet if you find yourself in the edit suite a month later looking at out-of-focus OOF shots on your edit bay, then you have a huge problem on your hands.

Panasonic needs to stop clinging to DfD as their single do-it-all AF solution and change to a hybrid Phase+Contrast AF system like Sony or Canon are using.  This continues to be the Achilles heel of the system and they need to own up to their mistake not double down on it with every camera release.

For many users, the AF on the camera is good enough and many Vloggers will shoot with it just fine but professional videographers will need to go to Canon or Sony for reliable AF as even the flagship Panasonic S1H suffers from even worse DfD AF performance.

What about the Slow Motion?

Now on to our website focus, that of slow motion video. The Panasonic Lumix S5 is capable of 60fps 4k video at 10 bit with an s35 crop in the sensor at that mode and also a cropped 150 and 180fps mode in 1080p Full HD recording.

The good news is that now we have AF tracking up to 150fps in full HD. The bad news is, it is contrast-detect DfD which means the same problems as the regular mode. But in practice, higher frame rates offer better AF performance as the camera samples more times/sec so it can lock into subjects better!

Slow-Mo Modes & Bit Rates:

  • 4k 60fps 10-Bit Internal
  • 1080p 120fps, 150fps slight crop and resolution loss.
  • 1080p 180fps – More severe crop and resolution loss.
  • H.264/MP4 4:2:0 8-Bit
    UHD 4K (3840 x 2160): 23.976p/25p/29.97p [100 Mb/s]
    Full HD (1920 x 1080):
  • 23.976p/25p/29.97p/50p/59.94p/100p/119.88p/180p [20 to 28 Mb/s]

So we now have what could be the let down of this camera and that is the low bit rate quality in 1080p slow motion of [20 to 28 Mb/s].  That is the exact same bit-rate as that on the 3-year-old GH5 camera which is not ideal. It is also more of a 720p image up-scaled to 1080p which looks aliased and soft.

We rather have a 100Mbps mode like that possible on regular up to 30p and 60p full HD recording modes.  Slow motion is crippled by using one-third of the bit-rate allocation in what we believe would be related to camera memory due to the faster frame rates. However, the S5 has a massive memory buffer that should easily be capable of recording 100Mbps 1080p at 120, 150 and 180fps options.

The excellent video preview by DPreview below at 11 minutes 7 seconds shows the slow motion mode samples in action with a heavy resolution loss at 1080p 180fps.

Panasonic S5 First Impressions Review by DPReview:

Another sample below shows many more slow motion clips which seem to be at 150fps which offer Continuous AF in Slow Motion up to that point. 180fps will not use AF. Forward to 7Min for the samples.

Lumix S5 Will be a Full Frame GH5 equivalent for $1998

Lumix S5 Slow Motion

The Lumix GH5 is still one of the best video powerhouse cameras ever produced. It doesn’t overheat, it shoots incredible 4k oversampled video at up to 60fps 4k or 180fps 1080p with near Full HD quality but it’s Achilles heel, the Micro 4/3ds sensor which is small and quite inferior in low light compared to Full Frame or even APS-C rivals.  The GH5s is the low light lower megapixel version with dual Gain senor which is actually very clean in low light and can go toe to toe with the best out there but has no IBIS which is a big loss.

Now Panasonic is set to announce the Lumix S5 Full frame mirrorless camera which essentially migrates most GH5 features into a full-frame body with nearly the same introductory price of $1998 USD but improves 4k 60p with 4:2:2 color at 10-bit instead of 4:2:0 8 bit on the GH5. You get IBIS, and also the 180fps Full HD of other S L-mount cameras by Panasonic.  It is still too early to tell what kind of quality the 1080p 180fps mode will be capable of but it does hold promise as the S1H and S1 do a pretty good job on these modes.

Lumix S5 Announcement Very Soon:

The camera will be unveiled Wednesday, September 2, 2020, at 14:00 UTC at the official Lumix site here: https://www.panasonic.com/global/consumer/lumix/s/s5.html

We also expect to see new low-cost L mount lenses for the system that will make the camera more appealing.  We just have to wait a few more days!

But what about the AF?

Yes, the dreaded DfD Depth from Defocus algorithm based on contrast detection is also present on this camera which means it will probably be inferior to systems that use dual pixel AF based on Phase and Contrast hybrid modes which are especially good for video. That means Sony and Canon will still have the upper hand here. Panasonic should keep DfD as an option but make cameras with Phase-detection AF pixels to be able to fully compete in this market. They are doing incredible hybrid still and video cameras with one feature missing, if they fixed the AF they would probably be the first choice of video professionals considering how good the cameras perform. Sadly Sony seems to be eating their lunch with the newly announced a7s Mark III with an AF system that rivals the best out there, in fact, it is so good that you can forget about focus pulling for most shots. The same cannot be said of the Lumix DfD AF contrast system.

We expect the 180fps Full HD Quality to be as good as the one in the S1H camera of the Lumix System. See this video to see the expected quality:

Sony a7s III Slow Motion is Hiding a Secret!

Sony a7s III Slow Motion

It’s here, yes it is finally here you are not seeing things. In what may be the most anticipated camera release in years, Sony has finally unveiled the a7s III video-centric mirrorless camera.  It has all the new performance benefits of processing and AF seen on other Sony bodies but now applied to a 12 Megapixel back-illuminated full-frame sensor geared to shoot pristine 4k and be able to shoot stills as a secondary function.  The original 5D from Canon shot 12.8 MP in 2005 when it was introduced and it is still being used out there by many professionals as it was and still is a wedding workhorse. However 15 years later which in the camera world seems like a century, we get a brand new Sony camera with 12MP and that is actually a great thing!

The slow motion on this camera has a lot of good but also some hidden secrets that you should know about before plunking your hard-earned cash. We get what may be the best 120fps 4k footage we have seen in any camera under 10k USD at full 4:2:2 10 bit quality which after looking at the samples left us with nothing but praise to see such a well-executed mode with the added benefit of being able to shoot nearly 1hr worth of it before the camera temperature spoils the party. Excellent performance!

The video specs from the a7s III above don’t tell the whole picture but do paint a very flexible camera with a variety of quality modes so you can choose anywhere from HD at 50Mbps on the low end to 600Mbps at 4k on the highest setting which is pretty ludicrous and will need specific CFexpress Type A cards that can be used alongside two SDXC UHS-II cards for a total of four cards which is pretty remarkable.

But what about full HD slow motion?

There is also a Slow and Quick motion mode which activates frame rate selection in FUll HD modes that can reach 120fps and 240fps in NTSC and 100fps, 200fps in PAL mode…

PAL mode: 1 fps, 2 fps, 3 fps, 6 fps, 12 fps, 25 fps, 50 fps, 100 fps, 200 fps

However, not all is good in the state of Sony Slow Mo…

The number of effective pixels in S&Q mode: 1408 x 804 at 240 or 200 fps. 240 or 200 fps not available when using [XAVC HS 4K], [XAVC S 4K], or [XAVC S-I 4K] file formats.

Yes, we get a reduced quality 1408 x 804 at 240 or 200 fps readout when you get the highest frame rates along with skipped lines, aliasing, and moire.  After looking at the samples we simply cannot recommend this camera for its Full HD slow motion capabilities. The image is mushy and low detailed in those modes and clearly it seems restricted by hardware limitations on the sensor which do not allow for a 1:1 frame extraction at those speeds.

But the 4k 120 and 100fps Slow Motion is great right?

Yes, this mode is not only great but it is superb in quality with up to 15 stops of dynamic range with S-Log 3, the best high ISO quality in a camera of this price range, 4:2:2 10-bit, full-time Autofocus in 100 and 120fps 4k with full eye and face detection with tracking. The camera is dependable, can record for nearly an hour in 4k 120p without overheating and can start to record again after a few minutes cool down thanks to its very capable internal heatsink which is a cut above what Canon was able to achieve on the R5 and R6 cameras which overheat after less than 30 minutes in pretty much every video mode.

One little nitpick on the 100fps and 120fps 4k mode you need to know:

The only real problem in this mode is a 1.1x crop from full frame when recording 100fps and 120fps 4k video. You get a 10% reduction in the field of view which seems to be tied to grabbing a 4k 1:1 pixel frame without full sensor readout inside the 12MP sensor. 4k needs only 8.3MP which kind of tells us that Sony cropped the sensor windowing mode to just read that portion in order to achieve the higher frame rate. That is not a really bad thing but something you need to know before shooting if you intend to use the same shot setup with different frame rates.  It can mess up your frame composition enough to require you to use markers on set to know which portion of the frame will be cropped and or the possibility to move back a bit to get the same field of view as regular 4k.

That said the 4k 100fps and 120fps mode shoots a beautifully detailed, noise-free, and artifact-free image that is the envy of many other cameras. You can use this mode on production as it shares the same quality as the 24, 30, and 60fps modes in the 4k shooting parameters.  It is that good, see the sample section below.
