Slow Motion Videos You Have to See!

Slow Motion camera releases are slow at this time of year but that doesn’t mean we have to be deprived of cool stuff to see. We have gathered a few slow motion videos that warrant your time and attention and surely push the art of capturing snapshots of time forward.

Even when these high speed cameras that in most cases are worth a lot more than the typical luxury midsize car, many creators are getting their hands on them and being creative in ways that could not be imagined in an earlier timeframe. From natural phenomena to technological feats, the footage has that mesmerizing quality that only this type of footage can instill on the viewer.  → Continue Reading Full Post ←

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:
