How AV.io SDI works
Once you’re ready to start capturing, you’ll need either a built-in or third-party application to capture video
and audio content with AV.io SDI.
The application communicates with AV.io SDI and negotiates a frame rate (frequency at which frames in a
video sequence are displayed) and frame size (size of a single video frame in pixels). Higher frame rate means
smoother video capture while frame size determines the aspect ratio of the video output as well as its size and
degree of crispness.
With the help of AV.io SDI, the content from your video source is automatically configured and captured on
your computer through your selected application. If the application requests a frame size that is smaller or
larger than your video source, AV.io SDI automatically scales the video for you. For consistent output, audio is
automatically resampled to 16-bit 48 kHz stereo audio.
No configuration required!
