Record a video
The Epiphan Capture Tool can record the images captured from your DVI2USB 3.0 as a video.
On Windows, you can choose to capture audio (see Configure audio) and can also alternatively choose to save
individual image files instead of a video, see Record as a series of images.
To record a video of your captured video source:
Step 1: Set the codec
Take this opportunity to select your encoding codec. Codecs are the software that take the uncompressed
video frames from the DVI2USB 3.0 and combine/compress these into a digital video file that you can view
with a player, share with a colleague or upload to a video sharing site, like YouTube.
By default, your operating system comes with some default codecs installed, no additional codecs come with
the Epiphan CaptureTool. You can choose to install third party codecs such as x264. Picking the best codec
for your use case is beyond the scope of this document, but you can find many resources (and debates) about
this topic on the Internet.
To configure the codec:
1. Connect your video source to the video grabber.
2. Connect the video grabber to a USB port on your capture workstation(use USB 3.0 for best
performance or if you plan to capture embedded audio).
3. Launch the Epiphan CaptureTool using the installed desktop shortcut. See Epiphan Capture Tool (Mac)
or Epiphan Capture Tool (Windows).
4. On Windows:Select theTools »Options menu item; a dialog box opens.
a. Select the Recording tab.
