Launch Control

Once AV-Playback begins, the first thing you will encounter is a convenient ‘Launch Control’ panel.

Launch Control

1

Default Folder Path

1. Default Folder Path
Establishing a default file store path is mandatory, hence why the very first-time AV-Playback is started from a new install, a folder browser appears. A default folder should be selected before trying to open or create a playlist. Once one has been established you are still free to deposit and retrieve files from any other location.  However, anytime a file browser is opened it will always use the default folder as its starting point. The default folder is especially necessary when setting up for use with a backup workstation. In that situation, it is important that the root event folder path be the same on both workstations.

Default Audio Device

2. Default Audio Device
Clicking will reveal a list of installed audio playback devices found on the local computer. Select the one AVP will choose everytime a new media element is added to the playlist.
 

NOTE:

If the last time your workstation was used, it employed an outboard audio device such as a USB to audio out or HDMI monitor audio out, and those devices are not being employed presently, there may no longer be a Windows default audio device and this list may appear blank. It is important that you always ensure you have a device selected before starting a new playlist or even loading a current one, especially if you plan to add any media to the playlist. If this is left blank all newly added media elements will not have an audio device assigned and when played any audio tracks will be mute.

Show Tool Tips

3. Show Tool Tips
When enabled each individual control will produce a helpful popup describing its purpose. Due to it sometimes interfering with mouse clicks, it is recommended that this feature be disabled once you feel comfortable with all aspects of the program.

Recent File List

4. Recent File List
This list displays all the most recently used playlist files in a reverse order with the newest at the top and working down from there. Double click on an entry to reopen and automatically load a playlist control window.
Use the 'Clr' button to remove all entries.

Pre-Buffer Nedia

5. Pre-Buffer Nedia
The app offers two different ways to handle performance variables and computer resources. By default, L1 pre-loads all playlist media elements into memory. This is preferred because it ensures a much more responsive control and there will be no jitter visible in a clip currently playing out to program while another is being loaded into preview. However, this method does require your computer to have enough memory to safely accommodate the gigabytes of space high-resolution video files require.
 
If you are having to work on a weaker computer but only need to playout clips once in while during to course of an event you can uncheck this  Now what happens is each time you select a clip only that clip will be loaded into memory greatly minimizing that amount of memory used.

Workstation Role

6. Workstation Role
One of AV-Playback’s key features is its ability to establish a node based a network hierarchy with multiple workstations containing the AV-Playback program.  
 
As in any hierarchy, there are multiple roles that members are given. In our case, there are three keys roles a given workstation can have.
Primary:
If a backup workstation is currently linked to the primary then anytime media is added to the primary’s playlist and if those files do not currently exist in the backup’s default file folder, the primary will automatically copy through the network those files directly to the backup unit’s default event folder.
 

Backup:

A workstation designated as a backup will support the primary in that it will remain in sync both with media elements and their properties, as well as with following along automatically with the primary’s current play status. This means if in the event the primary crashes and shuts down the backup will continue unimpeded.
 
Neutral :
When neither Primary or Backup is checked, the workstation effectively does not belong to any hierarchy, instead, it operates somewhat independently but can still link to the hub to receive transport commands from the Primary.

NOTE: This mode is the systems default.

Workstation Index

7. Workstation Index
If pairing with other workstations each must also have a unique index number and never be used more than once on the same network. Use this control to select that index number.
8

Play Command Delay

8. Play Command Delay
If designated as a backup unit and receiving transport commands from the primary, you can choose to delay activation of the play command.  This can be handy when you prefer to stager play times between a primary and its backup. The default is 0.
9

Start New Playlist

9. Start New Playlist
Clicking this will first display a file browser requiring you to give the new playlist a name and location.
 

NOTE: Once this is selected the Launch Control will automatically close.

10

Browse Playlists

10. Browse Playlists
As the name implies, this opens a file browser where you can find a particular playlist file to open.
 

NOTE: Once this is selected the Launch Control will automatically close.
