Videooptagere

Videooptagere is a term used to describe devices and software that capture and store video from various sources. In common usage the term covers both hardware recorders and software-based solutions that create digital video files for later playback.

Hardware videooptagere include standalone DVRs for security cameras, VCRs and digital video recorders used in broadcasting, and field recorders that capture video from cameras via HDMI or SDI.

Software videooptagere, often called screen recorders or capture programs, run on computers or mobile devices and digitize live input.

Inputs and formats: Typical inputs include HDMI, SDI, USB, and composite connections; outputs are saved files on hard drives or SSDs, memory cards, or cloud storage. Common codecs include H.264/AVC, H.265/HEVC, ProRes, and DNxHD, with containers such as MP4, MOV, and AVI.

Features: Many videooptagere offer scheduling, loop or continuous recording, timecode support, metadata tagging, multi-channel capture, and integrated audio capture.

Applications: They are used in home video archiving, professional production, live event broadcasting, surveillance, and game capture.

History and context: The concept evolved from analog video recorders to digital formats, with DVRs and capture devices expanding capacity and interoperability. Today, software-based capture on PCs and mobile devices is common, often paired with streaming workflows. Privacy and copyright considerations shape their use in public and commercial settings.
