M wrap, used in VHS and the D-1 (Sony) and D-2 (video) digital videotape formats, wraps the tape around the head drum in a pattern or in a tape path reminiscent of the letter M, around the left and right side of the head drum, 250 to 300 degrees around it where 180 to 270 degrees are active or used for recording, with two heads if 180 degrees ...
In the case of VHS, a linear control track at the tape's lower edge holds pulses that mark the beginning of every frame of video; these are used to fine-tune the tape speed during playback and to get the rotating heads exactly on their helical tracks rather than having them end up somewhere between two adjacent tracks. However, the exact ...

Since June 2007, YouTube's videos have been available for viewing on a range of Apple products. This required YouTube's content to be transcoded into Apple's preferred video standard, H.264, a process that took several months. YouTube videos can be viewed on devices including Apple TV, iPod Touch and the iPhone. [108]
Some video cameras and consumer camcorders are able to record in progressive "24 frames/s" or "23.976 frames/s". Such a video has cinema-like motion characteristics and is the major component of the so-called film look. For most 24 frames/s cameras, the virtual 2:3 pulldown process is happening inside the camera.
Whichever container is used, the video itself is not re-encoded and represents a complete digital copy of what has been recorded onto tape. If needed, the video can be recorded back to tape to create a full and lossless copy of the original footage. Some camcorders also feature a USB 2.0 port for computer connection. This port is usually used ...
Video tapes copied from DVDs encoded with APS become garbled and unwatchable. The process works by adding pulses to analog video signals to negatively impact the AGC circuit of a recording device. In digital devices, changes to the analog video signal are created by a chip that converts the digital video to analog within the device.
Double-system recording is a form of sound recording used in motion picture production whereby the sound for a scene is recorded on a tape machine that is separate from the camera or picture-recording apparatus. Double-system recording is the standard procedure on motion pictures that are originally photographed on film.
