What is the VVF file format?
.vvf is a video file format supported by many CCTV surveillance systems, particularly those manufactured by Speco Technologies and Pinetron. Unlike standard media containers, .vvf uses a proprietary binary wrapper specific to the DVR manufacturer. Opening a .vvf file often requires the dedicated player software bundled with the recording unit, as codec support depends on which compression format the given system uses to capture and store footage. .vvf containers can hold both video and audio tracks.
The video stream inside is typically H.264 or MPEG-4 compressed, wrapped in a manufacturer-specific header carrying channel number, timestamp, and recording metadata. Audio, when enabled, is encoded as G.711 mu-law at 8 kHz. Common recording resolutions are 704×480 (D1/NTSC) and 704×576 (D1/PAL), with some newer units reaching up to 1080p.
The .vvf extension is associated with Speco and Pinetron DVR product lines from roughly 2005-2008. Modern DVR and NVR systems from the same manufacturers now export standard MP4 files directly, making .vvf effectively a legacy format. Existing recordings can be converted to AVI using video converter tools that remux the internal compressed stream.
