VHS rip
VHS rip refers to the conversion of a VHS film into a digital format. This process is commonly known as ripping . The output analog video and audio signal is "intercepted" and converted to digital. This process is often associated with a loss of quality.
The reasons for this can initially be found in the source material:
- VHS only stores fields in a helical track
- Synchronization of the 2 video heads to display a full picture from two fields
- PAL / NTSC format
- Wear and tear and "temporal deterioration" of the videotape
- a maximum of one high fidelity sound is possible
- Copy protection mechanisms in commercial films
In addition, there are errors that arise from the technology used.
Overall, this leads to the following problems in the converted version:
- low horizontal resolution
- stripes in the picture
- rare dropouts of picture and sound
- poor sound quality
Legal basis
Commercial films, regardless of the carrier format, fall under the copyright law and may not be copied.
