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 ←

High Speed Video & Incorporating Sound!

High Speed Video Sound

Nick Moore the creator of the Youtube channel of the same name has done a primer video on the recording of audio along with high-speed video.  He goes into some detail about the usability aspects and limitations of recording audiothat is usable. Interestingly it can also mean you are better off faking the audio in post production for a better effect especially if you want it for a movie or tv show that demands quality audio.

The frequencies needed and data capture rate matter a lot in slow motion audio recording.  In the end, it is a balancing act of what can be heard by the human ear and what you can exploit on reasonable time frames. It is much easier for example to record audio up to 240fps but it becomes increasingly less usable the higher the frame rate goes. At 1000fps you probably will not have anything worth keeping. → Continue Reading Full Post ←

URSA Mini Pro Offers Pro Features and 120fps!

URSA Mini Pro

Blackmagic Design has announced a new camera today.  The URSA Mini Pro is a marriage of their higher end URSA camera with the still in the product line URSA Mini.  It offers built in ND Filters, 15 stops of dynamic range “which is huge for filmmakers”, tons of ports, in body buttons and controls and easy interchangeable lens mounts.

For our slow motion fans there is not a whole lot offered by the camera but there are some built in features.  60fps in 4k DCI and also at 4.6k full sensor resolution is very useful and keeps the trend with the 4k over-crank frame rates debuted in 2016 on several cameras. The other is 120fps at 2k windowed resolution which is passable but not ideal. However the slow motion on these cameras is high quality and seldom does it have artifacts. → Continue Reading Full Post ←
