4K video
Your servers are working with full frames, while competitors work with four quarters. Why do you do this?
The architecture of our servers allows us to work with full frame resolution. The architecture of competitors does not give them such an opportunity. It is worthwhile to understand that instead of recording 4K full frame they are working with four separate 3G quarters. This approach may have some problems. The main problem arises from the use of adaptive codecs which adjust their properties depending of the incoming image. It can turn out that one part of the image is very different from the other parts and in fact that will lead to different distortions in different quarters. Therefore, the image processed through quarters, will look a little different.
We use the IFRAME DCT based codec, which works with a full 4K frame and avoids such problems.
Another advantage of working with 4K full frame is that the image can be displayed to the user in any scale.
Why do you use ProRes 422 codec in your files for 4K non-linear editing?
The ProRes 422 codec which was not tied to 1920 × 1080 resolution was originally used by Apple Final Cut and other editors on Macintosh for movie applications. In contrast, for example, to the AVID DNxHD Pro HD or any other broadcast codec, its high resolution is native for 4K.
When we created our 4K servers, ProRes was the only accepted and normally working 4K codec that could be applied. We believe that the quality provided by this codec significantly exceeds the quality of files created by other editors.
How many channels are available for UHD / 4K? Can the available channels be configured in different numbers as input / output or are they fixed?
When working with 4K, up to 12 channels are available. Each of them can be assigned as an input or output, and can also be endowed with specific functionality in the Slomo.tv Launcher program.
What are the supported codecs for UHD / 4K?
Beside the dedicated DCT Based I frame codec, we use ProRes 422 for export.
What is the connection standard for UHD / 4K? (Single link 12G / Quad Link?)
We use 12G-SDI.
Is there a need to change the hardware in order for the device to work in UHD / 4K or is it provided by software / license?
This depends on your system configuration. If the configuration supports UHD/4K operation, you will only need a software license. Otherwise, a physical system upgrade will be required.
