How it 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 HD+.
The application communicates with AV.io HD+ and negotiates a
frame rate
(frequency at which frames in
a video sequence are displayed) and
frame resolution
(size of a single video frame in pixels). A higher
frame rate means smoother video capture while the frame resolution determines the aspect ratio of the
video output as well as its dimensions and degree of definition.
With the help of AV.io HD+, 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 HD+ automatically scales the video for you. For consistent
and widely compatible output, audio is automatically resampled to 16-bit 48 kHz stereo audio.
No configuration required!
