A frame grabber is an electronic device that captures (i.e., "grabs") individual, digital still frames from an analog video signal or a digital video stream. It is usually employed as a component of a computer vision system, in which video frames are captured in digital form and then displayed, stored, transmitted, analyzed, or combinations of ...
Fraps (derived from Frames per second) is a benchmarking, screen capture and screen recording utility for Windows developed by Beepa. It can capture from software that uses DirectX and OpenGL, such as PC games.
This version of Sound Recorder was included in Windows 7, Windows 8 and Windows 8.1, but did not make it to Windows 10. A second, different Sound Recorder was introduced in Windows 8.1, thus Windows 8.1 has two distinct apps called Sound Recorder. This second app was a Windows Store app and adhered to the design tenets of the Metro design ...
LosslessCut is a free, platform independent video editing software, which supports numerous audio, video and container formats. [4] [5] It is a graphical user interface, with MacOS, [6] Windows [7] and Linux [8] support, using the FFmpeg multimedia framework. The software focuses on the lossless editing of the video files.

Frame rate up-conversion (FRC) is the process of increasing the temporal resolution of a video sequence by synthesizing one or more intermediate frames between two consecutive frames. A low frame rate causes aliasing, yields abrupt motion artifacts, and degrades the video quality. Consequently, the temporal resolution is an important factor ...
Assuming a 60 Hz refresh rate, a benchmark tool may report this as 144 frames per second. However, the user will perceive less due to some frames existing for a tiny fraction of a display's refresh cycle. Micro stuttering is a quality defect that manifests as irregular delays between frames rendered by a graphics processing unit (GPU).
Synchronization of a decoding system with a channel is achieved through the use of the SCR in the program stream and by its analog, the PCR, in the transport stream. The SCR and PCR are time stamps encoding the timing of the bit stream itself, and are derived from the same time base used for the audio and video PTS values from the same program.
Lossy audio compression typically works with a psychoacoustic model—a model of human hearing perception. Lossy audio formats typically involve the use of a time/frequency domain transform, such as a modified discrete cosine transform. With the psychoacoustic model, masking effects such as frequency masking and temporal masking are exploited ...
