S-VHS tapes can give better audio (and video) quality, because the tapes are designed to have almost twice the bandwidth of VHS at the same speed. Sound cannot be recorded on a VHS tape without recording a video signal because the video signal is used to generate the control track pulses which effectively regulate the tape speed on playback.
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.
An audiobook (or a talking book) is a recording of a book or other work being read out loud. A reading of the complete text is described as "unabridged", while readings of shorter versions are abridgements. Spoken audio has been available in schools and public libraries and to a lesser extent in music shops since the 1930s.
Producing video CDs involves stripping out high- and low-frequency sounds from the video, resulting in lower audio quality than VHS. [23] While both formats need fast-forwarding to find certain scenes, rewinding to the beginning upon reaching the end is not required in VCD. The resolution is just half below that of common VHS resolution.
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 ...
Home video is recorded media sold or rented for home viewing. [1] The term originates from the VHS and Betamax era, when the predominant medium was videotapes, but has carried over to optical disc formats such as DVD and Blu-ray. In a different usage, "home video" refers to amateur video recordings, also known as home movies. [2]
Internet video streaming service YouTube offers captioning services in videos. The author of the video can upload a SubViewer (*.SUB), SubRip (*.SRT) or *.SBV file. [ 46 ] As a beta feature, the site also added the ability to automatically transcribe and generate captioning on videos, with varying degrees of success based upon the content of ...
As a final effort for VHS, the D-VHS system had significant advantages as a highly versatile domestic recorder (the other tape-based formats are DV and Digital8, which never gained any traction except as camcorder media), but given the wholesale move to DVD and then hard disk drive (HDD) recording, the format failed to make any headway into the video market.
