Veejay (software)
Veejay is a free visual instrument and realtime video sampler for Linux released under the GNU General Public License version 2 or later. Veejay functions as a video tracker and editing tool, as well as a realtime video sequencer and effects generator that allows for live interaction. Additionally, the generated content can be recorded to disk for future use. Development The project was started in June 2002 by Niels Elburg, Matthijs van Henten and Dursun Koca with the objective to provide a tool that would allow the user to play the video like a piano (a visual instrument) and record the resulting video directly to disk (video sampling). Veejay is not a traditional video editing application; The application aims for a high level of interoperability with other Audio/video applications through the use of Shared resources, Loop devices, various messaging protocols such as Midi, OSC and veejay's internal message system VIMS, but also through supporting third party modules su ...

C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer programming language. It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the measuring programming language popularity, most widely used programming languages, with C compilers avail ...

Video Sampling
In filmmaking, found footage is the use of footage as a found object, appropriated for use in collage films, documentary films, mockumentary films and other works. Use in commercial film Historical found footage is often used in documentary films as a source of primary information, giving the viewer a more comprehensive understanding of the subject matter. Director and cinematographer Ken Burns used archival footage in his films. ''Baseball'' (1994), his documentary television series for PBS, incorporates historical footage accompanied by original music or actors reading relevant written documents. Often fictional films imitate this style in order to increase their authenticity, especially the mockumentary genre. In the dramatized and embellished pseudo-documentary film ''F For Fake'' (1973), director Orson Welles borrows all shots of main subject Elmyr de Hory from a BBC documentary, rather than fabricating the footage himself. Stuart Cooper's '' Overlord'' uses stock footag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Video Editing Software
Video editing software, or a video editor is software used performing the post-production video editing of digital video sequences on a non-linear editing system. It has replaced traditional flatbed celluloid film editing tools and analog video tape-to-tape online editing machines. Video editing software serves a lot of purposes, such as filmmaking, audio commentary, and general editing of video content. In NLE software, the user manipulates sections of video, images, and audio on a sequence. These clips can be trimmed, cut, and manipulated in many different ways. When editing is finished, the user exports the sequence as a video file. Components Timeline NLE software is typically based on a timeline interface where sections moving image video recordings, known as clips, are laid out in sequence and played back. The NLE offers a range of tools for trimming, splicing, cutting and arranging clips across the timeline. Another kind of clip is a text clip, used to add text to a v ...

Audio Time Stretching And Pitch Scaling
Time stretching is the process of changing the speed or duration of an audio signal without affecting its pitch. Pitch scaling is the opposite: the process of changing the pitch without affecting the speed. Pitch shift is pitch scaling implemented in an effects unit and intended for live performance. Pitch control is a simpler process which affects pitch and speed simultaneously by slowing down or speeding up a recording. These processes are often used to match the pitches and tempos of two pre-recorded clips for mixing when the clips cannot be reperformed or resampled. Time stretching is often used to adjust radio commercials and the audio of television advertisements to fit exactly into the 30 or 60 seconds available. It can be used to conform longer material to a designated time slot, such as a 1-hour broadcast. Resampling The simplest way to change the duration or pitch of an audio recording is to change the playback speed. For a digital audio recording, this can be accomp ...

JACK Audio Connection Kit
JACK Audio Connection Kit (or JACK; a recursive acronym) is a professional sound server Application programming interface, API and pair of daemon (computing), daemon implementations to provide real-time, low-latency connections for both audio and MIDI data between applications. JACK was developed by a community of open-source developers led by Paul Davis (programmer), Paul Davis (who won an Open Source Award in 2004 for this work) and has been a key piece of infrastructure and the de facto standard for professional audio software on Linux since its inception in 2002. The server is free software, licensed under GNU General Public License, GPL-2.0-or-later, while the library is licensed under GNU Lesser General Public License, LGPL-2.1-or-later. Implementations The JACK API is standardized by consensus, and two compatible implementations exist: jack1, which is implemented in plain C and has been in maintenance mode for a while, and jack2 (originally jackdmp), a re-implementation i ...

Frame Rate
Frame rate (expressed in or FPS) is the frequency (rate) at which consecutive images (frames) are captured or displayed. The term applies equally to film and video cameras, computer graphics, and motion capture systems. Frame rate may also be called the , and be expressed in hertz. Frame rate in electronic camera specifications may refer to the maximal possible rate, where, in practice, other settings (such as exposure time) may reduce the frequency to a lower number. Human vision The temporal sensitivity and resolution of human vision varies depending on the type and characteristics of visual stimulus, and it differs between individuals. The human visual system can process 10 to 12 images per second and perceive them individually, while higher rates are perceived as motion. Modulated light (such as a computer display) is perceived as stable by the majority of participants in studies when the rate is higher than 50 Hz. This perception of modulated light as steady is known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interpolation
In the mathematical field of numerical analysis, interpolation is a type of estimation, a method of constructing (finding) new data points based on the range of a discrete set of known data points. In engineering and science, one often has a number of data points, obtained by sampling or experimentation, which represent the values of a function for a limited number of values of the independent variable. It is often required to interpolate; that is, estimate the value of that function for an intermediate value of the independent variable. A closely related problem is the approximation of a complicated function by a simple function. Suppose the formula for some given function is known, but too complicated to evaluate efficiently. A few data points from the original function can be interpolated to produce a simpler function which is still fairly close to the original. The resulting gain in simplicity may outweigh the loss from interpolation error and give better performance in ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
