A video camera with built-in microphones or line-in may not delay sound and video paths by the same amount. Solid-state video cameras (e.g. charge-coupled device (CCD) and CMOS image sensors) can delay the video signal by one or more frames. Audio and video signal processing circuitry exists with significant (and potentially non-constant ...
3-D audio (processing) is the spatial domain convolution of sound waves using head-related transfer functions. It is the phenomenon of transforming sound waves (using head-related transfer function or HRTF filters and cross talk cancellation techniques) to mimic natural sounds waves, which emanate from a point in a 3-D space.
The method was then repeated for playback, but with the projectionist hand cranking the film projector. "Single-system" sound recorded sound optically to part of the original camera film, or magnetically to a stripe of magnetic coating along the film edge. [citation needed] "Double-system" sound used independent cameras and sound recorders. The ...
Sound-on-film is a class of sound film processes where the sound accompanying a picture is recorded on photographic film, usually, but not always, the same strip of film carrying the picture. Sound-on-film processes can either record an analog sound track or digital sound track, and may record the signal either optically or magnetically .
The USB video device class (also USB video class or UVC) is a USB device class that describes devices capable of streaming video like webcams, digital camcorders, transcoders, analog video converters and still-image cameras.
FFmpeg is a free and open-source software project consisting of a suite of libraries and programs for handling video, audio, and other multimedia files and streams. At its core is the command-line ffmpeg tool itself, designed for processing video and audio files.
The shutter behavior of the camera influences aliasing, as the overall shape of the exposure over time determines the band-limiting of the system before sampling, an important factor in aliasing. A temporal anti-aliasing filter can be applied to a camera to achieve better band-limiting and reduce the wagon-wheel effect.
Some omnidirectional cameras contain wide-angle lenses on the front and rear to facilitate the recording of 360-degree video. 360-degree video is typically recorded using either a special rig of multiple cameras, or using a dedicated camera that contains multiple camera lenses embedded into the device, and recording overlapping angles simultaneously.
