  • (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.

  • Working with Audio/Video
    Working with Audio/Video Who on campus works with video/audio? • Network and Classroom Services (NCS) provides a comprehensive variety of services supporting the use of information technology in education. Their main service includes support for Technology Classrooms and other centrally scheduled spaces on both North and South campuses. They also provide support for video/audio related services as listed below. (Alternative contact: Beth Fellendorf 645-5526 Email [email protected]) • Digital Lecture Hall Recording Digitally capture and store recorded content for access via the web. This service mainly provides audio recording capabilities, but video recording can also be arranged in certain circumstances. Check Classroom Attributes for a list of classroom descriptions, including Digital Lecture recording capability. • Classroom Capture Services Record lectures, workshops or other classroom based events and makes them available on the web. NCS can provide these services in multiple remote locations as well as several fixed distance learning classrooms. The files created can be made available for on-demand viewing or can be streamed lived as an event takes place. These video files are often used for student review, as primary or supplemental course content and to preserve special lectures for multiple semesters. If you need to capture content quickly and do not require any post-production editing they may be the right service for you. Recordings can be produced in Real Media, Windows Media or Accordant format. Viewers can review a recording via streaming technology on the web and, if you desire, they can be given the ability to download and save the file. Live streaming is provided in either Real Media or Windows Media format.

  • Before You Begin Producing
    Producing with Camtasia Before You Begin Producing Before you begin to produce your video you need to decide how it will be shared; web based, CD, DVD. Once you have decided how you are going to share your video you need to decide which file format would be the best for that particular mode of delivery. The file formats you can save with in Camtasia include: AVI, Macromedia Flash (SWF), Windows Media (WMV), QickTime, Macromedia Flash (FLV), RealMedia (RM), Camtasia for RealPlayer (CAMV), and GIF animation. Click on Show more file formats to view all these options. AVI video file: AVI is recommended for CD delivery requiring the highest video quality. Once you produce your completed AVI files, use Pack and Show to bundle the Camtasia Player and Codec for easy delivery on CD‐ROM. It can also be edited by using Camtasia or other video editing programs. This is the type of format the original video will save as after recording with Camtasia. Macromedia Flash (SWF) movie file: An SWF file format can be used for videos that are 3‐5 minutes. This file format is good for using if you want to put your video on the internet and it is supported by most browsers. You will need the Flash plug‐in to view this video. Windows Media (WMV) streaming media file: A WMV file format creates smaller file sizes and works well for longer videos. It does not have to be downloaded and plays in Microsoft Windows Media Player. It is a streaming video file format. This type of file must be stored on a Windows Media streaming server.
