Chapter 5: Installation 43
IMPORTANT! Due to licensing requirements, Vizrt does not provide the codecs
required for local preview. Users must obtain and install their own codecs.
Note: Codecs are only required when local preview is done, as in the cases above.
Playout of the high resolution versions do not require a codec installation.
The following procedures will guide you through the necessary installation steps:
• To install codecs for local preview
• To set a preferred decoder
To install codecs for local preview
Codecs are available from several suppliers. The example below sets up support
for h.264 playback using the FFDShow MPEG-4 codec package and a Matroska
Splitter from Haali.
Note: You need to have your own license for clip playback as FFDShow does not
come with a decoding license.
1. Make sure you do not have any other codec packages installed on the machine
that interfere with FFDShow or the media splitter.
2. Download the Matroska Splitter from Haali
3. Download the Windows 7 DirectShow Filter Tweaker
4. Download the FFDShow MPEG-4 Video Decoder
• Make sure you have a license to use the codec
• Make sure you download a 32-bit version of the codec
5. Uninstall older 64-bit versions of the MPEG-4 codec
6. Install the Matroska Splitter from Haali
7. Install the Windows 7 DirectShow Filter Tweaker
8. Install the FFDShow MPEG-4 codec
• After installing the FFDShow codec package make sure that no applications
are excluded, especially Viz Engine (there is an inclusion and exclusion list
in FFDShow).
9. Set your MPEG-4 32-bit decoder to FFDShow (see how To set a preferred
decoder)
• You should now be able to preview video clips from Viz One
To set a preferred decoder
1. Run the Windows 7 DirectShow Filter Tweaker
2. In the appearing dialog box click Preferred decoders
