Epiphan VGADVI Recorder - Manual (Page 201)

Auto Settings
Automatic selection frame size using signal resolution
To assist with stream setup, stream frame size is now configured by default with the input signal's resolution and will
follow the signal's changes of resolution.
If the input signal changes, streaming and recording is stopped and restarted. Deslect Use current signal resolution
as frame size if your input resolution will change often and you don't want streaming or recording to stop and restart
with each change.
Automatic video bitrate selection
Based on the video encoder type, source resolution and stream frame size, the device now automatically calculates a
suggested bitrate that provides the best performance and quality trade off.
Examples for H.264:
l
640×480, 15 fps, - 1.4 Mbps
l
1280×720, 20 fps - 2.6Mbps
l
1920×1080, 30 fps - 6.5 Mbps
Preservation of source aspect ratio
A new feature, enabled by default, makes sure that the aspect ratio of input signals is preserved when encoded and
streamed. If an input video signal doesn't match the encoding ratio, a matte is applied and bars are visible at the sides
or top and bottom of the encoded stream. The color of the matte is customizable.
Universal Plug and Play (UPnP)
Device as a media controller
Enjoy the new live stream resume feature to ensure a digital media player automatically gets the stream when it
becomes available after the VGADVI Recorder restarts. Simply choose a stream and the UPnP-enabled media player to
control.
