What is a .WMV file?
WMV is Microsoft’s Windows Media Video format.
- Did you know
- Microsoft launched WMV in 1999 as part of Windows Media.
- A WMV file is wrapped in Microsoft’s Advanced Systems Format (ASF) container, which also carries metadata and optional DRM.
- The WMV 9 codec was standardised by SMPTE as VC-1, turning a Microsoft format into an open industry standard.
- As VC-1 it became one of the three mandatory video codecs for Blu-ray and HD DVD discs.
- WMV is a family of codecs rather than a single one, with versions tuned for everything from low-bitrate streaming to high definition.
- What Analyser shows you
- Read the container, codec, resolution, and frame rate of MP4, MOV, MKV, AVI, and WebM video, step through frames, and extract the audio track. Raw H.264/H.265 elementary streams (.h264/.265) are remuxed to MP4 in-browser so they play too, as are AVCHD camcorder files (.mts/.m2ts) - the video is copied and the audio transcoded to AAC. Sony cameras (Alpha, FX, RX) that embed a gyro / accelerometer "rtmd" timed-metadata track have that inertial data decoded and plotted - the same gyroscope and accelerometer samples Gyroflow and Catalyst Browse use to stabilise footage - alongside the ISO, white balance and capture time.
- Open a .WMV file
- Drag a .WMV file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
