The Formatt 82mm HD/DV Soft Effect Clear 1 Schott-Desag B270 Crown Optical Glass Filter is designed with the HD (High Definition) shooter in mind. Today's HD lenses are ultrasharp and often generate an image that is not as flattering to a subject as one might desire. This incredible technological breakthrough gives HD shooters the touch of softness they want but with no resulting loss of contrast or detail.

Using a sophisticated series of tiny "lenslets", the filter allows a certain amount of light to pass through unaffected. The rest is bounced around inside creating spherical aberration, avoiding the risk of secondary focus at short focal lengths, as may happen with other so called "soft" filters. These lenslets eliminate the moire patterns often generated by the highly sensitive surfaces in today's HD lenses and digital sensors.

Formatt, a company with three generations of professional filter-making experience produces every filter to the highest technical standards. The finest materials, together with state of-the-art production technology have resulted in a standard of optical excellence unmatched anywhere else.

The filter uses a series of small Plano-convex lenses mounted within a specially developed matrix which in turn is sandwiched between highly polished sheets of Schott B270 Super White optical lens glass.

Each filter is manufactured from Schott-Desag B270 Crown Optical Glass

It has absolute consistency in color and density to Kodak Wratten standards.

Its precision grinding and polishing result in unbeatable optical flatness that allows use on even ultra-long focal length lenses.

Filter edges are protected with a unique frame for maximum protection and easy handling.

Q: 6. I know it's not for this, but has anyone tried putting a quad 4k signal into this?

A: If you feed it a 4K UHD quad-link SDI signal (square division), it will display the 4 images as 1. However, since it's not designed for that there may be tearing in the video.

Q: 7. how the audio works?

A: MultiView 4 HD can be used with Blackmagic's Videohub Control Software that allows for audio input source selection with sources that have embedded audio; the multiview will display the audios metering.

Q: 8. Do all of the inputs need to be the same video format? I see it supports 1080p60 but will it accept a mix of 1080p60 and 1080p30 on the inputs?

A: No, each input is independent. We have several different resolutions coming into ours. From Blackmagic's website: "You get full frame re‑synchronization on all SDI inputs, which means that they can be any video standard and frame rate, and each input is completely independent of the others."

Q: 9. The USB C port is to connect to the interface. Can I customize the labels?

A: Yes, when connecting the USB-C port of the Blackmagic Design MultiView 4 HD to a computer, you can run the Multiview Setup Utility to customize labels. The software can be found here: https://bhpho.to/3qHsEvT.
