Is the first Cinema Camera from Blackmagic Design the touted “Gamechanger” 2013 - 105 Seiten Mittweida, Hochschule Mittweida (FH), University of Applied Sciences, Fakultät Medien, Bachelorarbeit, 2013 Abstract Die vorliegende Bachelor-Thesis beschäftigt sich mit der ersten digitalen Filmkamera der Firma Blackmagic Design. Sie ist insofern von besonderer Relevanz, da sie bei ei- nem vergleichsweise geringem Preis von ca. 3000 € eine Dynamikleistung von 13 Blenden bietet, ein eigenwilliges Design besitzt und zudem RAW Daten generiert. Au- ßerdem ist im Kamerapacket-Preis zusätzlich DaVinciResolve zur Farbkorrektur und UltraScope, eine Software zur Bildkontrolle enthalten. Damit bietet die australische Fir- ma derzeit den einzigen, für semiprofessionelle Produktionen erschwinglichen, RA- W-Workflow am Markt an. Blackmagic Design hat bei der Entwicklung der Kamera vie- le Wünsche der Independent-Filmcommunity aufgegriffen. Ob die Kamera eine Alterna- tive zur bis dahin im Independent-Filmbereich oft verwendeten Canon EOS 5D Mark II darstellt, soll diese Thesis erarbeiten.

  • (A/V Codecs) REDCODE RAW (.R3D) ARRIRAW
    What is a Codec? Codec is a portmanteau of either "Compressor-Decompressor" or "Coder-Decoder," which describes a device or program capable of performing transformations on a data stream or signal. Codecs encode a stream or signal for transmission, storage or encryption and decode it for viewing or editing. Codecs are often used in videoconferencing and streaming media solutions. A video codec converts analog video signals from a video camera into digital signals for transmission. It then converts the digital signals back to analog for display. An audio codec converts analog audio signals from a microphone into digital signals for transmission. It then converts the digital signals back to analog for playing. The raw encoded form of audio and video data is often called essence, to distinguish it from the metadata information that together make up the information content of the stream and any "wrapper" data that is then added to aid access to or improve the robustness of the stream. Most codecs are lossy, in order to get a reasonably small file size. There are lossless codecs as well, but for most purposes the almost imperceptible increase in quality is not worth the considerable increase in data size. The main exception is if the data will undergo more processing in the future, in which case the repeated lossy encoding would damage the eventual quality too much. Many multimedia data streams need to contain both audio and video data, and often some form of metadata that permits synchronization of the audio and video. Each of these three streams may be handled by different programs, processes, or hardware; but for the multimedia data stream to be useful in stored or transmitted form, they must be encapsulated together in a container format.

  • The Rise Ofra W Chtiis Flook
    The Rise ofRA W An Honors Thesis (HONR 499) by Daniel O. Johnson Thesis Adviser ChTiis Flook Signed Ball State University Muncie, Indiana May 2015 Expected Date of Graduation May 2015 1 Abstract Over the past decade or so, digital video has seen an enormous increase in popularity as technology improves and both amateurs and professionals alike make the switch from film to digital. Along with an increase in camera hardware, compression software has been improved drastically, allowing users a variety of options for every potential situation. Perhaps one ofthe fastest growing codec categories is the group of camera RAW codecs. By removing the in­ camera processing associated with other codecs, RAW files allow the user more control over their images/footage at the cost of larger file sizes. I look at the technical and visual differences between some of the most standard codecs and CinemaDNG, perhaps the most popular RAW file type. I also outline a potential CinemaDNG workflow and look at the history of RAW file types and what lead to their increase in popularity over the past few years. Acknowledgements I would like to thank Chris Flook for advising me not only on this project, but on projects over the past year. His total commitment to his work, students, and community is a continuing source of inspiration. I would like to thank Aaron Webster, for providing the opportunity that fostered my love for filmmaking. I fear without it I would never have pursued film to this extent. He has been a constant resource in the fields of gaffing, lighting, and post-production.
