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 ←

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 ←
