GoPro has released 3 new cameras including the Hero 7 Black which is now the flagship product for the company. The key feature is HyperSmooth which is a predictive stabilization technology based on scene analysis and sensor telemetry to accurately anticipate motion and correct the image to generate a gimbal-like smooth appearance to the video. When you see the footage it is clear it is a huge improvement compared to even the Hero 6 Black which had a pretty good stabilizer.
The Stabilization, however, is limited to 4k 30/60p and other resolutions below 120p but anything above 120fps will use the previous stabilization feature which is not predictive and have no stabilization support at all at 1080p 240fps which is the highest slow motion mode. No 480fps or other higher fps settings are available as the camera uses both the same Hero 6 Black sensor and the same GP1 system chip for this new camera.→ Continue Reading Full Post ←
Apple has released a preview video showing the video capabilities of the iPhone Xs in 4k 30, 4k 60 and slow motion 1080p 240fps. You can see in the liquid and sound part of the demo the quality delivered by the full HD slow motion but it is hard to judge per pixel sharpness and or artifacts from such a short high shutter video. We will need more real-world samples in order to see if there has been an improvement from the iPhone X of 2017.
We have isolated a part of the footage to see the slow-motion compression and we could detect aliasing in the edges, softness and compression artifacts which are typical of mobile phone high frame rates. The iPhone Xs seems to still have them to some degree. Color and motion on the codec seem to be excellent especially in 4k which looks extremely detailed and with more than acceptable dynamic range.→ Continue Reading Full Post ←
Blackmagic Design may have just solved the problem of RAW video capture for any camera and every type of user. In essence, it gives the benefits of RAW capture while allowing flexibility in file size depending on production needs. It is a compressed format but by using a clever demosaic algorithm that happens in-camera, it shrinks the file size much more than other formats while preserving quality and RAW features like White Balance, ISO, exposure, NR, clarity and color bit depth.
For Slow motion cameras, it may be the codec of the future as it will allow the best quality without the enormous file sizes associated with image sequences like DNG or other RAW formats. Being open source and free of licenses it aims to be adopted by the entire industry faster than other formats and will be free of the platform-specific nature of codecs like Apple’s ProRes which only works on Mac OS X. The Blackmagic RAW beta is already available here!→ Continue Reading Full Post ←
Apple just released 3 new iPhones and a 4th generation watch. These are all about the screen and speed and not really big new capabilities. It is all refinement and flawless execution but video fans will look at these phones as a continuation of last year’s specs with a better codec and possibly better bit rates and image quality but not much else. The iPhone X and 8 still remain relevant which is expected in an “s” upgrade cycle.
Gone are the big leaps of frame rates and Apple is capping at 1080p 240fps while completely ignoring rivals like the Galaxy S9,OnePlus 6 and Sony Xperia XZ series when it comes to super slow motion video. Apple was at the forefront of these technologies with the iPhone 6 but now have really rested on their laurels while the competition leapfrogs in video capabilities when it comes to frame rates. Others will point out that even when the high speed is restricted you will now get better quality footage in all modes which is certainly an upgrade.→ Continue Reading Full Post ←
The RED Hydrogen One phone has a lot to live up to but contrary to many doubters it may be just that good when it comes to video and photo quality. How good? By some accounts, it may be unrivaled by any phone currently and possibly for the foreseeable future thanks to the special software that is running on that last year’s Snapdragon 835 chip which is now outdated but still usable to create what RED touts as an imaging phone for the connoisseur.
We expect 4k quality in better codecs than the competition, with the ability to surpass 4k 60p which is the current phone upper limit for frame rates and resolution. As far as higher frame rates go we simply cannot find a lot of information when it comes to the way video is captured but read along to see something that may get a little closer to unraveling the mystery. New phone final body images have been released here in the forums.→ Continue Reading Full Post ←
Now that a few days have passed we now have the first few samples of what the Galaxy Note 9 is capable of in 960fps slow-motion mode. It shows about the same effective resolution as the Galaxy S9 and S9+ which share the same camera system. The Note 9 is supposed to increase the dynamic range but it is unclear how much benefit it will show in a resolution starved 720p high-speed mode.
The best selling factor for the Note 9 as a slow-motion device is the doubling of recording time to 0.4 seconds from the 0.2sec available on the Galaxy S9. This transforms into a 12.8-second video played back at NTSC 30p which makes it much more enjoyable than the 6.4 sec on the other Samsung phone.→ Continue Reading Full Post ←
