Web conferencing

Web conferencing may be used as an umbrella term for various types of online collaborative services including web seminars ("webinars"), webcasts, and peer-level web meetings. It may also be used in a more narrow sense to refer only to the peer-level web meeting context, in an attempt to disambiguate it from the other types of collaborative sessions. Terminology related to these technologies is inexact, and no generally agreed upon source or standards organization exists to provide an established usage reference.

In general, web conferencing is made possible by Internet technologies, particularly on TCP/IP connections. Services may allow real-time point-to-point communications as well as multicast communications from one sender to many receivers. It offers data streams of text-based messages, voice and video chat to be shared simultaneously, across geographically dispersed locations. Applications for web conferencing include meetings, training events, lectures, or presentations from a web-connected computer to other web-connected computers.

Adobe After Effects

Adobe After Effects is a digital visual effects, motion graphics, and compositing application developed by Adobe Systems and used in the post-production process of filmmaking and television production. Among other things, After Effects can be used for keying, tracking, rotoscoping, compositing and animation. It also functions as a very basic non-linear editor, audio editor and media transcoder.

Description

Adobe After Effects is software primarily used for creating motion graphics and visual effects. It allows users to animate, edit, and compose media in 2D or 3D space with many different built-in tools and third party plug-ins which can be downloaded from the Internet depending on what type of plug in the user is looking for. It also provides individual attention to variables like parallax and also user adjustable angles of observation.

Adobe After Effects is a layer-oriented program. Each individual media object like video clips, still images, audio clips, etc. runs on its own. In contrast, other Non-Linear Editing Systems use a system where individual media objects can occupy the same track as long as they do not overlap at the same time. This track-oriented system is more suitable for editing and can keep project files more simple. The layer oriented system that Adobe After Effects has is suitable for extensive video effects work and also key framing. Other compositing packages, especially the ones that employ tree or node workflows, such as Nuke and Fusion, are better suited to managing complex interconnected data flow within a composite. Adobe After Effects is capable of countering the problem somewhat by selectively hiding layers or by grouping them into pre-compositions.
