The Grass Valley™Kayenne™Video Production

Center ClipStore provides the means to

rapidly load and play clips that are integral to

live production, whether they’re packages for

replay, or animations used in transitions.

THE KAYENNE CLIPSTORE

www.grassvalley.com

The Grass Valley Kayenne ClipStore

incorporates K2 media server

technology by embedding either a

4-channel K2 Summit™or a 2-chan-

nel K2 Solo™. Each of these server

channels records and plays a video

and key pair. The ClipStore video and

key are kept in one single ﬁle (not

two ﬁles) so that video, key, and

audio are always synchronized with-

out the need to gang channels.

The ClipStore records and plays

back using AVC-Intra 100 com-

pression format. Clips imported

in DVCPRO HD, DVCPRO 25/50,

DV, and MPEG-2 will play natively.

The ClipStore supports record and

playback of embedded audio. The

server’s AES I/O is not used in this

application.

Control and use of the ClipStore

is completely integrated into the

Kayenne’s control panel and menu.

There is no need to ever use the

server’s native AppCenter Elite user

interface. Indeed, using this inter-

face could cause conﬂicts with the

switcher if used at the same time.

Of course the ClipStore provides

the means to ingest material.

Additionally, it provides the means

to edit and trim clips, and to

assemble a video/key/audio clip

from separate ﬁles. This is described

later in this document. However,

what is most important is the way

the ClipStore is integrated into the

switcher’s control system, so that

in addition to the manual loading

of clips using the switcher’s menu,

clips can be loaded, cued, and

played using E-MEM, macros, and

Q-MEM. It is this integration, which

makes the ClipStore so valuable and

versatile.

Unlike other K2 media servers and

media players in a facility’s network,

the ClipStore is intentionally isolated

from that network, and embedded

in the switcher’s control system.

The ClipStore is provided for direct

control by the technical director/

vision mixer, and is considered to be

local storage completely under the

user’s control. Let’s ﬁrst look at how

clips can be manually loaded and

played. Then we shall see how this

is done under E-MEM control and

Macro control.

Introduction

Fusion adds value to Grass Valley solutions by providing tighter

integration, unique functionality, and increased ﬂexibility when our

products are connected together—leading to more efﬁcient and faster

production. With Fusion, a ClipStore is part of the Grass Valley Kayenne

Video Production Center.

ClipStore playout is found in the Kayenne menu system

under Image Store/Record and Replay. This selection

has three tabs: Stills, Clips, and Clip Record and Edit.

When selecting the ‘Clips’ tab, the clips in the currently

selected folder are displayed as thumbnails or in a list

view. To load a clip, select a channel by touching its

output icon, and then touch the clip. As soon as the clip

is loaded and ready to play, the thumbnail is displayed in

the channel’s icon. There is a full range of motion control

for the clip, playing at unity or variable speed, forward

or reverse, and of course fast forward and rewind. The

menu also has a jog knob to precisely move the clip

as well as setting precise mark-in and mark-out points.

Also, most useful for animated backgrounds, is the abil-

ity to loop a clip continuously.

Loading and Playing

To build a show, it is important to include the load and

play of clips into E-MEM effects. This is done easily in

the same menu by using keyframe triggers. When the

‘KF Triggers’ button is pressed, the keyframable options

become jeweled in the menu, so they can be turned

on or off. A keyframe can optionally load a clip (mak-

ing it current), cue the current clip to mark-in, play the

current clip, and loop it. It is generally best to go to the

Master E-MEM section of the control panel and learn

the ‘Load Trigger’ into a new register. This keyframe

remembers the output, the clip name, and the directory

location. Then, insert after the current keyframe, a new

keyframe containing a ‘Play Trigger’. So the ﬁrst key-

frame loads the clip and the second plays the clip. The

ClipStore channels CS-1 to CS-4 default to MISC levels

1 to 4 of Master E-MEM. However these channels can

be assigned to any level. Most usefully, the channels

can be made deﬁnable and placed as sub-levels within

an M/E. In this case the M/E and the clip can be driven

from a local E-MEM panel rather than the master.

To create a macro for the ClipStore, ﬁrst ensure that

‘KF Triggers’ are turned off. Now ClipStore functions

accessed through the menu can be recorded into a

macro, including Load, Cue, Play, Stop, Rewind, and

Audio Mute. Initiation of the macro record can be per-

formed on the control panel or the macro menu. In both

cases it is the same, select a macro and press ‘Record.’

Then go to the ClipStore Menu, select the output chan-

nel, and then select the clip. Before recording the play-

ing of the clip it is necessary to insert a delay of at least

three frames before the play command is recorded; use

the ‘Insert Delay’ button to insert this delay. Not only

does the macro record the name of the clip, but also

the directory in which it is located—which is necessary

where different shows have the same clip name such as

‘Opening.’

Let’s now look at the process of ingesting material into

the ClipStore. This can be done in two ways: either by

recording video, key, and embedded audio directly, or by

importing ﬁles.

For recording there are two elements: video and key.

Either of these may contain embedded audio, although

it is usually associated with the video. A clip can contain

one to three tracks; the tracks being video, key, and

audio. These tracks can all be recorded at the same

time to form a clip, or recorded separately into clips

with only one (or two) tracks, and then assembled into a

single clip using the editing tools in the ClipStore editing

menu. Recording a clip can be open-ended or for a ﬁxed

duration.

Alternatively, channels can be controlled using

Kayenne’s Device Control Module (DCM) and learned

into Q-MEM (cue memory). To start, channels can be

loaded onto one of the letter buttons A through F by

rotating the top knob until a channel is displayed and

then holding down learn and pressing the letter button.

This assignment of the channel to a letter button (or say

all four channels to A through D) can be learned into

a Q-MEM on its own, so that the DCM can be rapidly

delegated to controlling the ClipStore. Once a channel is

selected, rotating the second knob scrolls through avail-

able clips, and pressing the load button loads the clip

onto the channel. The power of Q-MEM is fully utilized

when named clips, in and out points, and auto-play are

learned into one of the 100 Q-MEM registers together

with learning the delegation(s) to letter buttons.

Q-MEM registers can be recalled directly from the

panel. If auto-play was not learned into the cue, then

the TD can watch the clip being loaded on the moni-

tor wall, and then press the ‘Play’ button as needed.

Alternatively, the Q-MEM register number can be

learned into an E-MEM and recalled when the E-MEM

is recalled. By default Q-MEMs are stored in MISC

level 16. The Q-MEM sub-level can be made deﬁnable

and assigned to an M/E level. The advantage of using

Q-MEM registers in E-MEM effects is that the same

Q-MEM register can be used in multiple effects without

having to re-learn the cue. So, for example, the cue for

the animation “breaking news” could be recalled from

any M/E, or used in different effects such as full-screen

or in an over-the-shoulder shot. Of course, macros can

be used to recall Q-MEM registers too.

This process of assembly is very important where video

and key material is provided sequentially on a single

tape. This can be recorded as a whole, and then sub-

clips created, which are assembled so that video and

key are synchronous.

More and more, the industry is ﬁnding it easier to trans-

fer material as ﬁles. The ClipStore provides tools for both

import and export of ﬁles. The ClipStore supports import

of ﬁles in GXF, MXF, AVI, and MOV formats, however

it is only the GXF format that can have video and key

combined in the same ﬁle, so it is only GXF format that

is supported on export.

Ingesting Material (cont.)

The ClipStore menu editing tools allow you to trim clips,

create sub-clips from a longer clip, join clips together

(concatenate), and most importantly, combine tracks

from separate clips into a single clip. In the illustration

below, we see three different clips, one with video, the

second with audio, and the third with key. For precise

and accurate alignment, the individual tracks can be

offset (jogged) relative to the video. When the ‘Make

Clip’ button is pressed, a new clip is created containing

all three tracks.

Files can be imported directly by plugging a USB

memory stick into the Kayenne Menu Panel, or over

the network from any NAS. All directories mounted as

D:, E:, F:, etc. by the underlying Windows operating

system are shown in the Kayenne Library menu for the

ClipStore. Using this menu, ﬁles can be copied into and

out of the ClipStore. The left hand side of the menu is

always the source and the right hand side the target.

Files can be copied and deleted using this menu. Once a

ﬁle is imported into the ClipStore, it can immediately be

loaded and played. In a workﬂow that is centered around

the ClipStore, clips will be in the high-quality AVC-Intra

100 compression standard. In workﬂows that integrate

with other third-party equipment, ﬁles in native DV50,

DV100, or similar, can be imported and played.

The ClipStore itself is entirely conﬁgured using the

Kayenne menu. Additionally, to set up the ClipStore you

need to cable and conﬁgure its inputs used for recording

(sends from the Kayenne switcher) and its outputs used

for playout (returns to the switcher). Once this is done,

the ClipStore is ready for use.

Conﬁguring the ClipStore Using the Kayenne

Connection to the ClipStore is made by conﬁguring its IP

address in the Eng Setup / Node Settings / Frame Suites

Nodes & ID menu and pressing the ‘Enable’ button.

Setup and Conﬁguration

THE KAYENNE CLIPSTORE

www.grassvalley.com

The green LED indicator shows that the ClipStore

is operating and connected. Once the ClipStore’s IP

address is conﬁgured, each ClipStore channel automati-

cally appears in the Enables/Devices menu. The fol-

lowing illustration show how a four-channel ClipStore

appears in that menu. The ClipStore is not treated as

an external device and should not be conﬁgured in that

menu—doing so would cause conﬂicts due to a dupli-

cate conﬁguration.

Setup and Conﬁguration (cont.)

THE KAYENNE CLIPSTORE

www.grassvalley.com

The ClipStore itself is conﬁgured using the ClipStore

Conﬁg/Eng Setup menu. It is recommended that the

conﬁguration is ﬁrst retrieved from the ClipStore, using

the ‘Read from ClipStore’ button, the desired changes

are made to the conﬁguration, and then the ClipStore is

conﬁgured by pressing the ‘Send to ClipStore’ button.

Using this menu, various settings can be made, such

as conﬁguring the aspect ratio conversion or the freeze

mode.
