Sony RX10 IV & AX700 Slow Mo Samples Surface!

Sony RX10 IV & AX700 Slow Mo Samples

There is a lot of interest on the new Sony RX10 IV and new Sony FDR-AX700,  HXR-NX80 and PXW-Z90V Palm 4k Cam-Corders.   We have found a couple of new sample videos showing these cameras in action with HFR high frame rate modes. We estimate all four cameras to have comparable image quality in HFR mode but depending on the price a better overall codec with more detail retention.

However the best value out of all of them could be the AX700 which costs about the same as the RX10 IV but in a more professional body with lots of control that the SLR form factor lacks.  Also for a paid job you may be inclined to go with the more professional looking body to avoid judgmental stares.[...] → Continue Reading Full Post ←

Sony Palm 4k Camcorders Have 960fps!

Sony Palm 4k Camcorders

Sony has released three new Palm Sized 4k camcorders on the wake left by the RX10 IV all in one  1″ Sensor camera, these new cameras aim to produce professional results in 4k and with the use of broadcast features like 3G-SDI in the case of the Z90V allow for real time ENG and EFP production.

These cameras have the same  sensor and buffer mode as the RX10 IV camera but in a more traditional non SLR like form factor. The FDR-AX700 at the lower end of the range lacks a Proper microphone mount and XLR inputs with volume controls but they all share the same specs in lens 12x – and internal codecs aside from broadcast features.  This includes the HFR mode which seems to be identical to the RX10 IV offering 120fps continuous and up to 7 seconds of 240fps near full HD and reduced resolution 480fps and 960fps.[...] → Continue Reading Full Post ←

Sony RX10 IV Improves HFR Resolution!

Sony RX10 IV

As expected Sony has released the RX10 IV super zoom camera.  It is a good update to last year’s RX10 III which had a maximum HFR recording rate in quality priority of 2 seconds. This new model is, in essence, the exact same Sensor and HFR spec combination as the excellent Sony RX100 V which was our camera pick for 2016 when it came to price/performance for high-speed recording.

The RX10 IV has, however, a brand new AF system with 315 AF phase points in total with also 25 region contrast AF areas for extra accuracy.   The camera is mostly identical to its predecessor in appearance with improvements and refinements like a better screen and improved weather sealing. However, the imaging system processing is the exact same upgrade we saw in the 2016 RX100 V.[...] → Continue Reading Full Post ←

Sony RX0 Slow Motion Aims at Pro Action Market!

Sony RX0 Slow Motion

As expected by recent rumors, Sony unveiled the RX0 a compact action camera that is more high-end oriented than any action camera before it. A Crash cam for video production that has a large 1″ sensor with high sensitivity and S-Log 2 flat profile.  It also has features like focus assist, full 4k 4:2:2 HDMI output to an external recorder and a 1/32000 shutter like other RX series cameras that gets rid of most of the rolling shutter distortion apparent in other action cameras.

While the GoPro Hero 4 and 5 have access to a Pro Tune Log style video profile; the camera is not really geared for high-end production. The RX0, however, is limited to 1080p 60fps internally with 4k output from HDMI to an external recorder as the only 4k output option. This gives GoPro, Yi 4k+, and Sony’s Action Cam series an edge of internal 4k recording.[...] → Continue Reading Full Post ←

Sony IMX183 ExmorR Could Be In New RX Series!

Sony IMX183 ExmorR

Sony Semiconductor division has announced the new  IMX183CLK-J “Mono” &  IMX183CQJ-J “Color” Sensors in 1″ size. The sensor seems to be a step up compared to the ones used in the last RX100 and RX10 camera series.  While there is no mention in the press release of a stacked combo; the sensor itself should be able to be built on a high speed stacked memory package which should allow extreme frame rates at HD resolutions.

The sensor used in the RX100 V, for example, is a 1″ Exmor RS which allows for HDR capture in both photo and video modes. The new sensors announced are of the R variety “No video HDR” which could mean another variation of the sensor will debut with the RX100 VI.   Considering the cameras are due for a refresh this year we expect Sony to up the ante when it comes to read-out data speeds and use their stacking technology.[...] → Continue Reading Full Post ←

Fake Slow Motion Is It Worth It?

Fake Slow Motion

There has been a lot of work put it developing software that can interpolate frames for video editing and compositing applications. Twixtor in the late 90’s was perhaps the first time the technology could make something worthwhile and really produce acceptable results in a computationally acceptable timeframe.

Today the most used algorithm is Adobe’s Optical Flow in Premiere or Time Warp in After Effects which use vector directional plus acceleration of pixel values to derive in between frame data to generate new frame information from the preceding frame as point A and the next frame as point B.  The results can do some wonders to really slow down things above the frame rate ceiling of the camera.[...] → Continue Reading Full Post ←
