Alpa Platon Project: A rigged Hasselblad H6D 100c allowing to shoot extraordinary motion picture materials.

My Alpa Platon Experience

by Florian Friedrich, February 27th, 2019 The Alpa Platon project is dedicated to adding everything a filmmaker can dream of to a Hasselblad H6D-100c camera. But let’s start from the beginning… Have you heard about large sensor digital filmmaking yet? The usual sensor size in digital filmmaking is Super 35 (S35 ~25mmx13mm, depending on the camera and aspect ratio) and some cameras like Sony Venice (36mm x 24mm) started to use full frame or bigger sensors recently. A larger sensor in general means that you can capture more pixels of the same size or increase the size of pixels on the sensor. While both approaches have their specific advantages (resolution or noise level), the downside is that you need bigger lenses to fulfill the needs of a larger sensor. So, of course, the cost for appropriate lenses considering all the high-quality glass and optics can be tremendous and must be […]

NASA 8K HDR video for free

by Florian Friedrich, last update: April 29th, 2019 When I saw that NASA shared some 8K footage ready to download on its website, I immediately thought I want to see this on a 8K TV!Seeing the ISS and earth in that kind of resolution seemed fascinating to me. Mission1: Download the file from NASA I do have access to a 75″ Q900 TV from Samsung which has the desired 8K resolution, so I downloaded the MP4-Video which was encoded to 709 SDR, MPEG level MAIN 6.2 with about 140 MBit/s. So there’s no HDR or Wide Color Gamut for 8K space material, really? I had put the file onto a USB Stick and plugged it into the TV which rejected to play it. Oh wow, the first 8K Video from NASA and the first 8K TV on the market don’t know each other? I immediately wanted to act as a […]

8k spatial resolution versus contrast pattern

The perception of spatial resolution is influenced by its contrast. So in order to see the resolution, there’s also a minimum contrast requirement. With increasing contrast, the information in the image may benefit from higher spatial frequencies. A good example are stars in the sky. They are much smaller to the eye than pixels of 8K-TVs and still we’re able to see them!   Further information about this 8K pattern will follow.

HDRmaster 8K: Software zur HDR-Analyse und für HDR 10+

München, den 10. Dezember 2018– Das neue HDRmaster 8K für Windows 10 ist eine innovative Videoanwendung für essentielle Aufgaben im Bereich der Qualitätskontrolle und der Erstellung von Metadaten bei HDR-Videoproduktionen. Die Anwendung unterstützt Bildauflösungen bis zu 8K (7630 x 4320 Pixel). HDRmaster 8K ist Nachfolger von HDRmaster v2, einer Profi-Software die von Firmen in den Bereichen Ultra HD Blu-ray Authoring, Broadcast, Postproduktion, sowie Filmstudios und Lehreinrichtungen weltweit eingesetzt wird. Die vollständige Pressemeldung als PDF auf Deutsch finden Sie hier.   Anwendungsbereich der HDR-Tools Um den Zuschauern die höchstmögliche Bildqualität auf HDR-Geräten und -Displays zu liefern, müssen Produktionshäuser die Signalpegel und HDR-Metadaten ihrer auszuliefernden Videos perfekt im Griff haben. Fehlende Optimierung von Signalpegeln und Metadaten führt nicht nur zu Kompromissen in der Darstellung auf dem Fernseher beim Zuschauer, sondern verschlechtert auch die Effizienz der Kompression durch eine unnötig erhöhte Datenmenge sowie zusätzliche Kompressionsartefakte.   „Es ist leider keine Seltenheit, dass gemasterte und an […]
