Last week the site The Information posted a piece stating the possibility of GoPro being bought out by Chinese electronics company Xiaomi which are the makers of the main competitor to GoPro in the same form factor with the Yi camera line. We liked the Yi 4k+ last year as it delivered pretty acceptable quality in 4k 60p in a GoPro like the body+enclosure design. We were not thrilled by the bit rates or the slow-motion quality but it was in the running for the best alternative action camera with a lower price.
If the rumors are true Xiaomi will be consolidating the Action camera market and improving the Yi camera line overnight by rebranding it to GoPro as the name might be just as valuable as the technology being acquired. Most of the current Yi camera products share the components with pre Hero 6 Black cameras like the Hero 5 Black as they were based on the Ambarella chips that GoPro used for a decade.→ Continue Reading Full Post ←
There is an aura over the Panasonic GH5s that has not been seen in a m43 camera possibly ever. It is mainly due to the outstanding low light quality in 4k 24, 30p and 60p that beats full frame cameras like the Canon 5D Mark IV and competes head to head until ISO 25,600 with the king of low light the Sony a7s Mark II. But as always, our focus is on the high frame rates which the camera also does quite good on.
The 4k 60fps quality is very close to the 30p quality which means excellent and you can shoot at 60p at night without worrying about noise. The 240fps mode which is a first for a Lumix camera in full HD means that the camera aims to compete with Sony RX series cameras that have stacked sensors. We believe the quality to be acceptable but not good enough to be broadcast quality as stair stepping jaggies are all over the frame with the occasional moire pattern on fine detail that can break a shot.→ Continue Reading Full Post ←
The Z Cam E1 which delivered excellent quality 4k footage from a tiny package and was able to do 720p 240fps frame rates “at less than ideal quality”, however, a new Rumor from 4/3 Rumors here shows a Twitter message that hints at a new Z E2 m4/3 camera that is able to do 120fps at full 4k resolution. If this turns out to be true it could yield further performance improvements in 1080p and 720p along with higher quality that could be usable.
As far as linear specs go a 120p 4k pipeline could in theory yield 480fps 1080p and 960/1000fps 720p without going out of spec. As we have come to know over the years, however, it is usually wrong to extrapolate these specs to the maximum possible metric as the sensor or memory could be bottlenecks that limit the performance. So this rumor could have some legs to it and NAB 2018 could be the show that makes 4k 120p a regular feature for cameras.→ Continue Reading Full Post ←
Sony made a headline splash with the Xperia XZ2 last week but samples of the slow motion or HDR were not widely available to really see what the phone could do. Even today they are few and far between but we were able to find some to make a pretty good assessment of the quality offered in video mode.
We were quite impressed to find a resolution gain that it is quantifiable in 1080p 960fps Full HD mode slow motion that is greater than previously thought. It is still not true 1080p quality but it is slightly higher from 720p which in turn makes this XZ2 Phone the best 960fps phone out there for quality. The Galaxy S9 is close behind but with a severe aliasing increase by reducing the data captured.→ Continue Reading Full Post ←
The new Sony Xperia XZ2 from Sony is their flagship phone for early 2018. It has a lot going for it like 4k HDR movie mode which is a first for a phone and from what we can see it really makes a difference in dynamic range and color on the footage. It also has the latest Snapdragon 845 SoC for increased performance with the battery savings to boot.
What we are interested however is the slow motion high frame rate capabilities which after the Galaxy S9 with 960fps HD 720p announcement, Sony needed to respond accordingly. Well, Sony has done so and they now claim 1080p 960fps slow-motion video on their XZ2 phone which is a one up on the Galaxy with more resolution. However, it is not all that rosy as companies seem to equate a frame size with video quality which in many cases is not even close to spec.→ Continue Reading Full Post ←
