We’ll begin this series by discussing one of the most important features in any pro nonlinear editor: color correction. The first thing you need to do before beginning any type of color correction work is to determine what "correct" color looks like. Rarely does your computer screen display colors correctly.
In this installment of Cut Lines, we’ll look at cropping and rotating several images at once and how nesting your composition can make it easier to manipulate your images together.
One issue with AVCHD is that (like HDV) it’s based on a codec that is not really built for editing in the way that DV is. DV is an intraframe codec, which means that each frame of video is compressed using redundancies within the frame itself, and thus can be reconstructed and interpreted by your computer’s processor without having to refer to other frames in the video stream to gather the necessary image information. HDV, being MPEG-2-based, and AVCHD, being H.264-based, use both intraframe and interframe compression, which means most of the frames in your video stream need to be referred to other frames to gather all the image information that constitutes the frame. Because all this cross-referencing is so processor- and memory-intensive, it can really slow down your editing.
Once you have successfully captured your video clips, you will want to edit and arrange them to create you movie. It is very rare to flawlessly capture exactly what you need, with the exact in and out points that you want. You will need to trim unwanted frames and footage from your clips.
The HTML 5 video element has the potential to liberate streaming Internet video from plugin prison, but a debate over which codec to define in the standard is threatening to derail the effort. Ars takes a close look at the HTML 5 codec controversy and examines the relative strengths and weaknesses of H.264 and Ogg Theora.
We are so accustomed to watching television that we easily overlook the limited resolution of the television screen. Compared to TV, even VGA looks good. Although both use a similar display monitor, they differ in both the way the screen is 'painted' and in how much information can be placed on the screen. To design effectively for interactive television, it is essential to understand the technical constraints of the medium.
The availability of powerful yet easy-to-use multimedia tools enables technical writers to consider a powerful new form of embedded user assistance: show-me help. This paper provides an overview of who is currently using show-me help--some current research, some history, and some definitions. It offers some guidance in choosing tools, designing show-me help, and deciding when to include then, concentrating on consideration of your users, potential topics, subsequent releases, and translation. It also suggests how show-me helps can be reused as part of product education and single-sourced into user assistance from the Web.
When you write a script for a video (or when you create a general outline), you can avoid the problem of the eternal video — which I refer to as a sense of rambling — by simply keeping the video short. Don’t try to cover too much ground. You can generally speak about 100 words a minute, so keep that in mind with your script. 200 words is a good length. If you don’t believe me, when you watch videos, look at the video’s time counter and note when you start losing your attention. My patience times out at about three minutes. So I always try to keep my videos at three minutes or less.
Technical communicators can expect to see an expanding role of video in product documentation, training, and marketing presentations. This is largely due to three factors: (1) digital video lowers the technology and cost thresholds to bring video to the desktop, (2) video makes sense for conveying information involving movement, and (3) video is a popular consumer medium. To technical communicators, video is a new medium in which visual communication is key. Narration and text are subordinate. Technical videographers must learn and apply video design principles and good production practices to create effective video that communicates the information.
Digital does not experience signal loss or degradation...what goes in, comes out.
In this highly interactive workshop, Amy Jo Kidd will present participants with a fun exercise on task-based, structured writing that illustrates in an immediate and clear way how to use Darwin Information Typing Architecture (DITA) to manage a company's inventory of content. The workshop is a must for students, the curious, the fearful, and the eager who have heard the buzzwords—content management, structured writing, single sourcing—but could not get beyond the mind-fuzz that buzz creates.
Rich or multimedia content is, of course, expensive and time-consuming to produce. So publishers that go to the trouble want plenty of their users to see it. Alas, this isn't always the case -- because links to such packages are often tucked away or presented in ways that Web users don't easily see.
Remember that when you speak to a reporter, you're potentially speaking to an audience of hundreds or thousands of people. Try not to appear negative or confrontational. A hostile attitude will make it difficult for viewers to take your point seriously.
Designers of DVDs have failed to profit from the lessons of previous media: Computer Software, Internet web pages, and even WAP phones. As a result, the DVD menu structure is getting more and more baroque, less and less usable, less pleasurable, less effective. It is time to take DVD design as seriously as we do web design. The field needs some discipline some attention to the User Experience, concern about accessibility for those with less than perfect sight and hearing, and some standardization of control and display formats.
Although electronic whiteboards come in several sizes and shapes, their main function is the same – to capture written annotations, notes and drawings and store them for future reference. This is accomplished with infrared sensors, radio-signal-emitting pens, plasma overlays and other technologies. The end product is a file of digitally stored notes that can be e-mailed, posted online, or printed and handed out to an audience immediately after a presentation or training session. Beyond these basic features, some electronic whiteboards are interactive – letting you connect a computer and projector to the whiteboard to combine its features with common software programs. A Microsoft Excel spreadsheet, for example, can be projected onto an interactive whiteboard where it can be marked up with colored pens to highlight important numbers or trends. Or, using an interactive whiteboard's touchscreen feature, a presenter can navigate the Web using a finger to move the cursor and double-clicking with taps on the screen. Even videoconferencing functions have been integrated into electronic whiteboards in the past year.
e-Video is divided into four major sections: Opportunity, Production, Compression, and Delivery. Although these can (and must) get a bit technical to be useful, I found Alesso's style understandable.
Current developments in high-definition technological systems for home viewing link definitively with early Home Cinema, as practised from the late 1890s, as an alternative to public spectatorship. The traditions of Home Cinema, in encompassing degrees of informality, interaction and control within domestic exhibition, served to lay foundations for a televisual experience which, today, having come full-circle, is defining itself once more as `Home Cinema'.
They say a picture is worth a thousand words. In this day and age of digital media, video on your web site can be priceless. Whether you have a corporate, social networking, or video streaming site, video instantly captures your visitor’s attention and describes your product and services quickly and effectively. Due to its large install base, Flash video is now the de-facto standard in internet video delivery. With recent updates to Flash 9, Flash Player adds the capability of playing H264 encoded video in full screen mode, making the delivery of Flash videos on the internet not only practical, but efficient as well. In this article, I will examine a few different techniques for delivering Flash videos over the internet and compare the advantages and disadvantages of each.
