• Playlist Control

Playlist Control

At the heart of AV-Playback is the playlist unit control. It is with this control all primary functions are performed.

Playlist Control
Things to Consider:


View Style

1. View Style
Use these to select the view style of the actal playlist dat table. You can choose between a standard list style (default):
or the large thumbnail grid style:

Open Button

2. Open Button
Browse and load an existing playlist file. If the control already has playlist open, this action will close that file first before loading the selected one.

New Playlist

3. New Playlist
Use this to create a new blank playlist. It will open browser window enabling you the name the new file and select where it will be saved. As with ‘Open’, if the control already has playlist open, this action will close that file first before loading the new one.

Select Output Screens

4. Select Output Screens
Clicking will bring up the ‘Display Output Selection Tool’.Use it to select the desired display output. Once assigned, that display will be owned by the playlist unit. If the playlist is open no other playlist unit will be able to utilize it. 

Add Base Media Element

5. Add Base Media Element
Clicking this will reveal the Media Selection Tool:
Click on “Browse” to search for the desired media.
Once files are selected, click open. At tis point the browser will disappear now to complete the add be sure to click on “Apply” on the selection tool.
NOTE: If adding base elements to the playlist you are permitted to select multiple files at the same time within the file browser. However, if you are selecting layer elements to a base, only one element can be added at a time.
If instead you wish to add a live capture input, then select an available source from the “Capture Device” list.
NOTE: You cannot add media files and a capture source at the same time. If anything, other than “NONE” is selected that selection will overrule any selected media clips and the capture source will be the only thing added. 

Edit Mode

6. Edit Mode
To edit certain details of a media clip, this must be enabled. When enabled you can double click and on either the clip’s title, fade rate, link delay time and the punch in or out time to manually edit those properties.

NOTE: While enable you will not be able to select any clips for play.


Clear Selected

7. Clear Selected
This will clear the selection of all media clips. Any that were selected for ‘Preview’ or ‘Program’ removed from dispaly.

Auto Clip Start

8. Auto Clip Start
When checked a clip will automatically begin playing as soon as it is selected. This also applies to selections generated when pressing the Previous or Next buttons.

Previous & Next

9. Previous & Next
Click to select for preview, either the clip before or after the currently selected clip. If there isn’t one selected it will go from the one currently in program. If none are selected it will begin at clip number one.

Preview Control Group

10. Preview Control Group
Here you control transport functions, audio gain and output assignments for any media that currently resides in the preview slot. You also have the option to override what is outlined in the timeline section, So let’s say you need to do some last minute tweaks to a clip before it is taken to program but you currently have media playing out to the house, When the override is enabled the timeline control will now reflect your preview material, allowing to make the necessary changes and once done you can remove the override and the timeline goes back to showing program status.
CAUTION: While the preview override is active the running program clip may not be able to respond to time line triggers required for linking and looping of media. Only override just long enough to perform preview edits then return to displaying program.

Temporary Hold/Freeze

11. Temporary Hold/Freeze
When enabled a playing clip will pause and remain visible at its punch out time point and will remain there until the ‘Kill’ button is pressed. This feature overrides any of the clips individually enabled functions such as, Fade, Link, Repeat and Hold. Once the ‘Kill' button is pressed, the clip will return back to its starting point and this feature will become disabled.

Temporary Loop

12. Temporary Loop
When enabled a playing clip reaching its punch out time point will automatically return to the punch in point and begin to play again. This looping action will continue until the ‘Kill’ button is pressed. This feature overrides any of the clips individually enabled functions such as, Fade, Link, Repeat and Hold. Once the ‘Kill' button is pressed the clip will return to its starting point and this feature will be disabled.

NOTE: Both Temp Hold and Temp Loop can be enabled prior to the start of a base clip.


Program Transport Group

13. Program Transport Group
These should be self-explanatory but there are a few details that need to be discused:
"Kill" will stop program play and automatically blank the video output as well as return the base clip and any layers back to its starting position.
"Prev Tag" Advance clip's position to the previous cue tag from your current position. Note: Using this while clip is running will only go back to the closest tag. To go back further you will need to pause playback.
"Pause" is a toggle. When paused the ‘Take’ button will be disabled you must click the ‘Pause’ again to resume play.
"Next Tag" Advance clip's position to the next cue tag from your current position.
"Take" will always begin play at the base clip's punch in point.

GoTo Time Out

14. GoTo Time Out
Clicking any one of the four will instantly reposition the base clip to either 60, 30 20 or 10 seconds before the base clips punch out time. If clip is playing when pressed it will remain playing even after it is repositioned.

Scrub Bar

15. Scrub Bar
The green scrub bar moves across the span to reflect the play head’s current position. The small timecode display on top of the scrub line will always show the actual position within the clip’s native extents, regardless of current punch points. By clicking on and dragging the trackbar icon you can manually set the current position of the play head.
It’s also possible to move the scrub bar in one frame increments hover the mouse cursor over the track bar and then use the mouse’s scroll wheel to move its position. You can also use the left and right arrow keys on your keyboard to move by 3 frames at a time.
All adjustments can be made even while the clip is currently playing.

Set Punch In / Goto In Point

16. Set Punch In / Goto In Point
"Set In" Click to set base clip’s punch in point to the current scrub line position.
"<<" Snap clips current position to the punch in point.

Set Punch Out / Goto Out Point

17. Set Punch Out / Goto Out Point
"Set Out" Click to set base clip’s punch out point to the current scrub line position.
">>" Snap clips current position to the punch out point.


18. Rewind
While pressed the clip will rewind its position at a rapid pace. 

Fast Forward

19. Fast Forward
While depressed the clip will play forward at the faster then normal speed.
Click on the down arrow button to acess the Fast Forward context menu.
Auto Mute Audio:
When fast forwarding the audio play heads are still active so to prevent the excess noise from being heard you can enable this feature to mute the audio for as long as the fast forward is engaged.
Speed Value Slider:
Adjust this slider to set the default faster than normal speed used when fast forwarding.

In Preview Clip Title

20. In Preview Clip Title
Once a clip is selected for preview its title will appear here.
Selecting a clip for standby is simply performed by clicking anywhere within the clip’s row, except for its checkboxes (Fade, Link, Loop & Hold), this is because those properties can be set without enabling the ‘Edit’ button.

NOTE: If the ‘Edit’ button is enabled you cannot make a preview selection.


In Program Clip Title

21. In Program Clip Title
When the clip in preview is moved to program, its title appears here. The ‘Preview Clip Title’ text label will become blank until another clip is placed into preview.

Timecode Display

22. Timecode Display      
Count down mode.                              Elapse time mode

Transport Status Icon

The above icons illustrate the transport status of either preview or program. That last icon represents an base clip that is set to loop. Digits will also appear inside the loop icon that represent the total number of iterations that have occurred since it began playing.

Time Display Constraints

24. Time Display Constraints     
Clicking this button will cylce through the three different modes that are used to determine the duration extents used for calculating the running time displayed.
(BLUE)(Default) Total duration is within the boundary’s set by the punch in and out points.
GRAY) The clips native duration no matter what the punch points are set at.
(PURPLE) Duration is the span between cue tags. If viewing countdown, the display will countdown to zero at each cue tag. When play moves beyond a tag the display will begin the elapsed countdown to the next tag and so on.  

Time Display Direction

25. Time Display Direction  
These two separate buttons control the counting direction of the current clip position. When the down arrow is red, the display is counting down to zero. Conversely, when the up arrow is green then the display is counting up from zero.
The color of the time display will also change. It will be red when counting down and green when counting up.      

Clip Data Fields

26. Clip Data Fields
The data fields contain pertinent information as well as user editable properties.
TIP: You can rearrange the column order within the playlist grid, by clicking on the column header and dragging it to desired location.
Clicking most anywhere within the row will select the clip and place it into standby, with the, exception of its checkboxes (Fade, Link, Loop & Hold). Clicking these only effects, a direct change to that function’s current state.
Once the clip is selected the row’s back color will become yellow. This signifies the clip has been loaded into the video engine’s memory, and is now ready for play.
When a standing by clip is instructed to play, it is now considered “In the gate” and the back color will turn to red.
If you left click and hold you can then drag that clip and all it settings to any other index position within the list.
To edit certain properties, ones that requires the need for direct typing of a value, will first require you enable the ‘Edit’ button. When ‘Edit’ is enabled you will be unable to select a clip for standby, instead mouse clicks are treated as a request to edit a particular field. 

TIP: Right clicking on any row will cause a small popup preview window to appear, which contains a thumbnail of a video frame at five seconds in. This time value is fixed and cannot be changed.


Clip ID

*** Current screen shot is out of date and does not illustrate this column correctly.***
By default, when you add a new media element the system will insert a sequential index number. All single numbers will have a zero in front of them. Users however can enter any alphanumeric combination they like after the clip is in the playlist. There are some rules though. You can only use letters A to Z and number 0 to 9. No special characters or punctuation marks allowed, and there must always be at least two or more characters.
NOTE: It is this ID that you type when using a keyboard to select a clip for play.

File Thumbnail

28. File Thumbnail
By default, this column is hidden but can be made visible by selecting in the main menu; Settings || Show Thumbnails.
NOTE: When 'Show Thumbnails' is disabled, right clicking anywhere on clip's row will cause a popup thumbnail to appear.

Layer Grid

Display Button

29. Layer Grid 
Display Button
Click on this button to display the layer sub grid for the selected base clip.

Clip Title

30. Clip Title
Displays the clip’s current title. By default, the title is the file name for the clip. This field can be changed by enabling the ‘Edit’ button, double clicking on the cell and then type in a title you prefer. 

Total Running Time

31. Total Running Time
This field shows the clips total running time the punch in and out points.

Auto FadeSettings

32. Auto FadeSettings
Each video or audio clip can be configured to perform a gentle fade in and out. By default, each new clip added will have this feature enabled along with a 1 second fade duration.  This feature can be enabled or disabled at any time, even while the clip is playing.
However, to change its fade rate you can either at any time right click on it to show a popup slider control or is you choose to manually type in a value you must first enable the ‘Edit’ button, then double click on the text field.

Note: This value cannot be empty, it will only accept values of 0.1 seconds or greater.    


Link & Loop Settings

33. Link & Loop Settings
Any clip can be linked with another. When one clip ends the next one will begin to play automatically.
To create a link, both clips their Link enabled. It is not required to have any of the linked clips next to one another in the list but the link flow is from top to bottom, so consider that when determining a sequence.
If you wish, a delay of the next clip’s start can be implemented. By default, this vale is ‘0’.
To edit the value, first enable the ‘Edit’ button and then double click on the text field to type in a new value. This delay value must be set on the clip receiving the linked start. This way you can customize the delay value separately for each linked clip.
As with the link any individual clip can also be repeated automatically. When this is checked, the clip will loop continually until the ‘End’ button is pressed.
The same delay value can be applied to the end of each iteration if you do not wish to perform a “seamless loop”.

NOTE: By default, it is understood that when the loop is used, it will be seamless. When first checked the ‘Fade’, Link and ‘Hold’ features will be disabled. This strategy is helpful if you are instructed to loop the clip after it has already begun playing. Once it has been checked, you can re-enable the ‘Fade’ and/or adjust the loop’s delay time.


There however one exception to this rule… The disabling of those of those other features will not occur if the clip already has its ‘Link’ enabled and is part of a sequence of linked clips,   


Looping Linked Clips:

A sequence of ‘linked’ clips can also be looped. If the last linked clip has its ‘Loop’ enabled, then when that clips ends the first linked clip will begin playing. This entire sequence will continue until the ‘End’ button is pressed.  
You can limit the total number of times a clip or linked group will repeat by entering a number other than zero. Once at the end of the last iteration the clip will automatically stop and return home. Otherwise if set to zero the element will continue indefinitely until you press the ‘Kill’ button. 

Clip Hold

34. Clip Hold
Like the ‘Temporary Hold’ function, when checked, each time the clip played it will pause/freeze right at the punch out point and remain visible until the ‘End button is pressed’.

NOTE: Enabling this will automatically disable the ‘Fade’, ‘Link’ and ‘Loop’ functions.


Play Speed

35. Play Speed
If you require a clip to play either faster or slower than normal speed on cue, then you can enter a custom number between 0.1 and 4.0. (1.0 = normal speed) This value will be saved and used each time the clip is played.
Note: It is best to perform any changes while the clip is stopped. Any changes to this value wile a clip is playing may cause erratic behaver. This value cannot be empty, it will only accept a value of 0.1 or greater.

Clip Properties

36. Clip Properties
These fields display more of the clips properties. Native resolution the clip was rendered at, frame rate and its bit stream size.

TIP: The bit stream size is a property you need to pay close attention too, for it is the main reason for a clips possible rough playback performance. Our tests have shown that on an average quality pc, the bit stream size should not exceed 400 megabytes. Of course these assessments may vary from computer to computer but you should think of this limit as a good rule of thumb. 


Punch/Set Time Points

37. Punch/Set Time Points
These show the current punch in and out timecode points. By default, when a clip is added to the playlist these will show the clips native extents. You can edit these directly by fist enabling the ‘Edit’ button and then double click on either, then you proceed to type a timecode point in manually. Click enter when done.

NOTE: When manually entering a value you must adhere to the standard timecode format, insuring that the colons appear between each element of time, (hh:mm:ss:ff).


Display Confidence


38. Display Confidence
In some situations where a video file has a bit stream size greater then what the computer can handle comfortably, you can try and disable the program confidence view for just the selected clip. The confidence view does contribute greatly to the overall stresses undergone by the CPU and GPU. Perhaps by eliminating this factor, you may be able to get the clip to playout smoothly.

Audio Settings Button

39. Audio Settings Button
Left click to mute audio output from only this element. Click again un-mute.
Any video or audio clip can be assigned its own separate audio output. By default, when you add a clip to a playlist it will use whatever the app as set as its Default Audio Device
After a clip is added you can right click on this to display a popup menu which contains both a level control as well as list of currently available audio outputs. Adjusting either will only affect the individual element When overriding the system default with a different device the change will be permanently saved and not affect the app default or any other element. 
NOTE: In most situations, the first time AV-Playback is started on a computer it will query Windows for what it has as the default audio device and automatically assign it as the apps default. Although there have been situations where no default was found. This can happen when at a previous time the computer used a particular HDMI monitor as default audio out but now without the monitor attached there is no longer a default. When no default is assigned to AV-Playback, anytime you add an element to a playlist it will load with no audio output assigned. It is very important to always have a default audio device assigned to the app.

Clip Settings Button

40. Clip Settings Button
Clicking this will open a Settings Control Window. Please refer the link for detailed information on iits use.

Info Button

41. Info Button
Clicking this will display window with a detailed information of the selected clip’s properties.

Notes Column

42. Notes Column
If you choose, you can save user notes to any base clip within a playlist. 
Click this button to display a small text entry window.
Type in what you like and then click the save button.
Once saved your note will appear as a popup tool tip anytime the cursor is hovering above the line item.
You have the option of displaying notes fulltime in its own text column by selecting the option in the "Visible Columns" window accessed by clicking on  Settings||Configure Grid Columns

Trash Button

43. Trash Button
Click to permanently remove clip from playlist.

Layer Sub Grid

44. Layer Sub Grid
For detailed explanation on adding and manipulating layer elements please refer to the Add Media Layers tutorial.

Add Layer Link

45. Add Layer Link
Click this link to add media as layers that will appear on top of the base element.
TIP: For more information refer to information found in the description of the playlist “Add” button.

Timeline Control

The timeline control gives a graphical display of the base element as well as any additional layer elements.
The overall time span of a timeline is determined by the base clip’s native duration. The hash marks are automatically scaled based on the clips total length. Their placement interval on the line is approximately one second for each small mark and five seconds for the larger. For long running clips, the interval will change to reflect minutes instead.
46. Timeline Control
Depending on the type of element and whether it is a base or layer, its icon will appear and behave differently.
NOTE: When the clip is currently in preview it will appear yellow. In program it will appear red.
Video and Audio Clips:
Other then providing a visual reference, the icon has red vertical bar at the left and right edges, these are your trim point handles. You can use them to set the clips punch in or out points by dragging them to a desired position.
When used as an additional layer and if that element’s duration is shorter then base you can drag the entire icon and line up its left edge to any desired starting time point within the range of the base clips TRT.
If a motion layer has been set to loop, you set a total duration for the repeating clip by grabbing the right edge of the icon and dragging it out to the desired end time.     
NOTE: The overall length of the icon is determined by the elements native duration. However, the actual starting point of the element is this plus any additional span to reach finally reach its punch in point, e.g. left trim handle.      
Still Image Files and Live Capture Input:
If these element types are used as a base clip, since they have no clock to run the timeline the icon will provide only a visual representation providing no user control. However, when used as layer to a video or audio base layer, the icon will by default span the entire running time of the base clip but to control when the element appears on and off screen you can use either it’s left or right trim point handles to drag them effectively to the desired start and end time points.  
For all element types; anytime it has had its in or out point trimmed the area between them and the elements extents will appear as a faded color with a crosshatch pattern. 
NOTE: To provide activation of additional layers, the base clip must always be either be a video or audio clip. It is from these clips the timeline’s clock is derived. Without a clock, layers cannot be triggered to appear on screen.  
The green scrub bar moves across the span to reflect the play head’s current position. The small timecode display on top of the scrub line will always show the actual position within the clip’s native extents, regardless of current punch points. By clicking on and dragging the trackbar icon you can manually set the current position of the play head.
It’s also possible to move the scrub bar in one frame increments hover the mouse cursor over the track bar and then use the mouse’s scroll wheel to move its position. You can also use the left and right arrow keys on your keyboard to move by 3 frames at a time.
NOTE: All adjustments can be made even while the clip is currently playing.

Cue Tag Marker

47. Cue Tag Marker
A cue tag is a marking tool you can add to a timeline. When a marker is in place and the ‘Time Display Constraint’ is set to the purple , the timecode display will show a running countdown to each tag. When playback moves beyond a tag the display will begin the elapsed countdown to the next tag and so on. These tags can be useful when the director needs to issue instructions to other cue members during playback.
You can add as many tags as you like, and they will be automatically saved to that clip. After a tag as been inserted you can move it on the timeline by dragging it to the desired point in time.
To remove a tag simply drag it all the way off the timeline to the left or right.
A brief crib note can be added to each tag by right clicking it and typing your note into a simple dialog box.
After the note as been saved it will appear as a tool tip anytime the cursor is hovering over it.
Tags can also be an easy way jump the play-head directly to any point within the clip by using either the ‘PREV TAG’ or ‘NEXT TAG’    buttons.

Add Cue Tag

48. Add Cue Tag
Use this to add a ‘Cue Tag’ to the timeline. By default the tag will first be placed at the ‘Scrub Line’s’ current position.

Sync To Hub

49. Sync To Hub
Use this to activate a link to the AV-Sync Hub. This as a toggle so click once to connect, click again to disconnect. When connected anytime a Primary workstation issues a transport command, such as Take, Pause, Kill, Scrub and Time Out will cause the exact same command to occur on the other linked playlists. This also makes it possible to sync playback of multiple destinations simultaneously.
NOTE: One AV-Sync Hub anywhere on the network must be up and running for this function to be enabled.

Backup Status & Update Button

50. Backup Status & Update Button
Another exclusive feature is to have one networked workstation serve as a direct backup to the primary unit. The pictures above show the five different states of the backup’s status. These will only appear within the one workstation designated as the primary. Refer to Setup Backup Workstation to learn more
