iPhone Xs Slow Motion Official Apple Sample!

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 ←

FUJIFILM X-T2 vs X-H1 Slow Motion Quality Comparison by CVP!

The FUJIFILM X-H1 which offers 120fps 1080p slow motion was a worthwhile effort to offer high frame rates that are usable to their video-centric base. It still was not as good as the Sony or Panasonic slow motion options due to aliasing, moire, and noise but with a little post work, it could be used with success in an edited piece.  FUJI then with a firmware update for their stills flagship the X-T2 allowed the camera to now shoot the same 120fps 1080p slow motion which makes sense considering they use the same sensor on both cameras.

The camera site CVP has done a full comparison review here which pits the X-H1 against the X-T2 to see which camera strengths are ahead on each body and if it makes sense for X-T2 owners who are invested in a FUJI lens system to upgrade.  Their findings are interesting and as far as slow motion it is clear that while they use most of the same imaging pipeline; the X-H1 has the edge with less crop, less aliasing, and better artifact suppression when using the 120fps slow motion mode. → Continue Reading Full Post ←

Sony 1000fps Sensor for Smartphones Developed!

Sony 1000fps Sensor

You have to hand it to Sony for their continued hardware innovation. The sensor technology that brought you the RX Camera series with stacked CMOS Technology; which is DRAM included as a middle layer along with signal processing makes it possible to capture data at tremendous pixel rates in the sensor block which leapfrogs competitors products.

That same 3-Layer stacked design is now unveiled on a cellphone geared sensor with a maximum performance at 1080p 1000fps and 4k 60fps. It is using the same buffer DRAM technology that will let you record for a limited time window and then save and process on your handset.   Considering the speed quoted it is not out of the question to expect the Sony RX series of cameras to reach or exceed this level on upcoming iterations. → Continue Reading Full Post ←
