How good is the iPhone 6s at Slowmo?

6sPlusLineupSlowMotion2

Now that a couple of weeks have passed it is clear that the camera in the new iPhone 6s is better than the previous model in every single way.  It has 12MP instead of 8MP, it has UHD 4k recording in video and has 120fps 1080p slowmo which is up from 720p.   The dynamic range is on par with the previous model but with the added feature of less noise and artifacts due to new in sensor technology and software processing.  While most users will not notice much in the way of improvements; they are there and especially if you look at the video mode the new iPhone is a fantastic upgrade from the regular 6 model.

The 120fps 1080p mode is very good and the detail is retained as long as there is not a lot of minute detail and extreme numbers of objects/changes in the scene. It is not as good as regular 1080p but it is close as there is not a lot of detail loss especially when using Macro mode.  If you want it to shoot a single water drop it should do great but if you are recording assorted splashes the codec will break apart and macro-blocks will start to invade your scene. It works very well for people and large scene objects and a lot of detail is preserved.  The 240fps mode is also improved in the artifacts and noise which means the processing is improved as you can see much less aliasing and moire.  It is still not true 720p but it is very close.  As of now we think the iPhone 6s has better slow motion quality than the GoPro Hero 4 Black and the Sony Action Cam Sony FDR-X1000V .   It is the best slowmo phone available in quantity as of today.  The New Nexus 6P has 720p 240fps to compete with the iPhone but no realistic samples besides the Hummingbird Video which is still unconfirmed exist.   This will change in the near future when users get their hands on it. → Continue Reading Full Post ←

iPhone 6s Slow Motion Samples Released!

6sPlusOne

It has now been a few days since people first got their hands on the new iPhone 6s and 6s Plus. One of the new features is it’s ability to shoot higher res slow motion at 1080p 120fps and a somewhat improved version of the 240fps at 720p with less artifacts.  We have found a few samples that may show you the quality of the slow motion modes in action.  It is clear from an initial perspective that 720p 240fps is higher resolution with less noise and aliasing artifacts and also that the 1080p 120fps mode while higher resolution it is not exactly the same quality as the 1080p video of the phone. There seems to be an apparent softness or slight resolution loss with heavier compression in this mode.    This however doesn’t detract much from the fact that both the 120fps and 240fps modes have been improved and that is a good thing.

GoPro Hero 5 Rumored Specs!

Hero5Negative

The GoPro Hero 4 series has been quite successful for the company and many are thinking what can they offer next when it comes to camera specs.  The Hero 4 Session showed that miniaturization and form factor change is possible at GoPro and we will not be surprised to see a change in shape and size on the Hero 5 to reduce it’s footprint.   The GoPro mount has also been holding back the platform miniaturization as to remain compatible with accessories and grips of all kinds.  What could happen is to remain compatible but introduce a stronger and smaller mount with some sort of adapter for backward compatibility. This transition will open the way for more portable and stealthy cameras.

Our biggest hint of where the platform is going is what the new Ambarella H1 chip provides.  It is an evolutionary chip-set with a few features geared to UHD recording which suggest that 4k will be the focus going forward. → Continue Reading Full Post ←

ARM Cortex A72 Capable of 120fps at 4k!

arm-a72-590x330

The specs for the newest and greatest ARM phone chip the A72, show that it is close to 3.5 times more powerful than ARM’s previously released Cortex-A15. It is also powerful enough to record and process 4K video at a rate of 120 frames per second.  

While the specs of this 32 and 64bit capable chip look mighty impressive it is a predictor of things to come. These reference design chips are used for example by Apple in their A architecture because the company has  an architectural license agreement with ARM; that has proved to be an amazing performer because Apple tweaks the design to perform incredibly fast in their devices sometimes above 50% from the reference design in some specific applications. → Continue Reading Full Post ←
