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.→ Continue Reading Full Post ←
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.→ Continue Reading Full Post ←
Sony has been relatively quiet about phones since the Xperia 1 II roll out. However, rumors have been heating up on the Xperia 5 II, which is a lower-cost alternative to the flagship phone but very nearly as capable without the best screen or construction but not skimming on features. The latest rumor mentions a spec sheet that makes it a 4k 120fps recording phone which may show that handsets still are seen as innovators when it comes to cameras since very few consumer devices in the camera world can record at that frame rate.
We were not very happy that Sony basically killed the super slow motion mode on the Xperia 1 II phone which kind of showed that Sony was putting stills and regular video at the forefront without making compromises in sensors that needed to shoot at higher frame rates. Sony chose to do cleaner regular frame rate video and stills that were better than any Sony phone before at the cost of not having a do it all sensor. Slow motion from Sony was all but killed but the Xperia 5 II now makes us second guess that fate…→ Continue Reading Full Post ←
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.→ Continue Reading Full Post ←
Schlieren Imaging has always been a very narrow and specialized field of imaging. It can visualize air perturbations in a fluid-like way that can show the reach in this case of someone’s breath and heat dissipation to see if a mask makes a large enough difference in transmission of infected airborne particles compared to no covering.
Samsung will start shipping to stores the Galaxy Note 20 and Galaxy Note 20 Ultra on August 21, 2020. This new phone is the latest and greatest on their line of ultra-performance devices that offer little compromise at a premium price. It has a 108MP sensor on an f1.8 lens on the Note 20 Ultra 5G version that can do crazy zoom and pixel averaging in low light. The more pixels you record even if they are small let you do more computational photography processing to average noise and artifacts out to end with a crisper lower resolution image that is pleasing and punches above it’s weight.
However, not all is good news since the video mode in Samsung devices when it comes to slow motion has been stalling in the last iterations to a max 960fps mode in HD 720p which is now on this phone an interpolated 480fps mode that is slowed 2x to 960p. This makes the Note 20 line an inferior slow-mo device to even the Galaxy S10 which offers real 960fps. The good thing here is a full second of recording at 480fps on the Note 20 line which translates to 16 seconds playback at 30fps and 32seconds with interpolation.→ Continue Reading Full Post ←
