Image Store Audio Requirements
The K-FRM-LIC-RAMREC license option is required for all K-Frame systems including the
S-series to support Image Store audio. Standard and Compact K-Frame, and the
GV K-Frame X systems also require the K-FRM-IMG Image Store board.
Importing Movies with Audio to Image Store
K-Frame systems with Image Store, can import .AVI and .MOV files with audio. The Image
Store imports up to four channels of audio per stream (even if the .AVI or MOV file contains
more than four channels of audio). The Import Facility will find and select the first two
stereo pairs of audio, starting with the first audio stream. The Import Facility then searches
in order, audio streams 2, 3, and 4 in the import file, and will only select the first four audio
channels it locates for import. Empty audio channels are silent if the import file does not
contain at least four audio channels.
Import Formatting for Image Store Audio
Grass Valley uses Version 8.10.2015 of the open source FF MPEG utility with the 7.13.2013
library to convert imported movies and audio to the EIF/EAF format used by Image Store.
Information is widely available on the Internet for the .AVI and .MOV file formats supported
for import and conversion.
Image Store Supports Audio for SD
Image Store now supports audio for Standard Definition formats of 525 and 625 at both 4x3
and 16:9 aspect ratios.
Image Store Audio Levels in Loop Mode
When playing a movie with audio in loop mode, the Image Store will play the audio from
the first frame of video immediately after the audio from the last frame of the movie. If the
audio waveform at the end of the movie does not match the audio waveform at the
beginning of the movie, there will be a discontinuity in the waveform at the loop point that
can cause disturbances in the audio output. This can be avoided by careful matching of the
audio waveform at the beginning and end of the movie; one method of doing this is to is to
ramp from silence to the desired level at the beginning of the movie and fade from the
desired level to silence at the end of the movie.
Configure Image Store Audio Outputs
Any of the four Image Store Output Audio Groups (four audio channels in two stereo pairs,
per group) can be configured as the output group for any licensed Image Store channel.
The All button allows you to assign the same Output Audio Group to all Image Store
channels.
1 Select User Setups , Suite Prefs , Image Store in the menu.
Note: Image Store will not import corrupted Audio channels but will
instead replace them with silence.
