Capture recording is the process of capturing data or events from a live source and saving them for later use. It is a broad concept that encompasses audio and video capture, screen recording, sensor data logging, and the capture of network or system activity.

In multimedia production, capture recording records video from cameras and audio from microphones, often with synchronization and accompanying metadata such as timestamps or scene markers. In computing and software, screen capture records the contents of a display for tutorials, demonstrations, or debugging. In surveillance, digital video recorders or network video recorders collect CCTV streams. In research and networking, packet capture records network packets for analysis.

Practices vary by domain. Common components include hardware capture devices or software-based capture tools, and outputs such as video files (for example MP4 or MOV), audio files (WAV or AAC), screen captures (series of images or video), or log formats (such as pcap for network data). Key considerations include timestamps, frame rate, resolution, encoding codecs, and storage requirements. Quality and reliability concerns involve latency, frame drops, and synchronization between streams, as well as data integrity and backup strategies.

Legal and ethical considerations are important when recording environments where people may be present. Privacy laws, consent, and notice requirements can govern when and how capture recording is performed, stored, and exploited. International and sector-specific regulations may further constrain usage, retention, and access to captured data.
