Grass Valley Vertigo XG - Manual (Page 3)

Supported file formats for playback (Vertigo XG & Intuition XG) Page 3 of 9
Preface
The purpose of this document is to provide a guideline for the playback capabilities of the Vertigo
graphics engine that is used in Vertigo XG and Intuition XG devices. It is important to note that these are
general guidelines only. The only 100% sure way of validating that you are operating the system within
its capabilities is to verify the performance status indicators on the XG device’s output (see section on
Using Statistics ).
Supported Files for Playback
The file formats listed below are natively supported by all Vertigo graphics processors. This means that
all of the listed formats can be played back on either a Vertigo XG or Intuition XG as long as the file
meets the format requirements.
A format that is not listed below may or may not be suitable for playback on a Vertigo XG or Intuition
XG. In general, file formats that are not natively supported will need to be transcoded on ingest. For
example, .MOV files are NOT natively supported by Vertigo XG and Intuition XG devices, therefore they
must be transcoded to MXF on ingest. Transcoding to VAF can only take place if the file has the
following characteristics:
• An animation codec
• Single track multi-channel audio (24 bit, 48Khz)
VAF (Vertigo Animation Format)
VAF is a proprietary optimized format for the playout of animations with alpha on Vertigo XG and
Intuition XG devices. Cell animations and .MOV (with alpha) content is converted to the VAF format on
ingest.
MPEG2
• MPEG (IBP)
• Extension: (.mpg, .mpeg)
• Codec: MPEG2 (IBP)
• Recommended Bit Rate: SD@9Mbps; HD1080i@19-25Mbps
• Max. Bit Rate: 50Mbps
• Audio Codec: MPEG Audio Layer 2/Layer 3/AAC (16 bit, 48Khz)
• Audio Tracks: Single
• Audio Channels: Stereo
• MPEG (I-Frame)
• Extension: (.mpg, .mpeg)

• Audio Tracks: Single
• Audio Channels: Stereo
MXF-wrapped MPEG-2 is also supported, as long as the MPEG-2 clip meets the requirements listed
above. Note that in MXF, only PCM (uncompressed) or AIFF audio is supported.
