Warning

  • Make sure Please verify that Just Out is not started automatically using the “Login Items” functionality of the system preference pane “Users & Groups” or “General → Login Items”. Instead, use “Stay AliveAlive” to start the application automatically after a restart of the Mac or a crash.

The Just Out application provides the final output (Virtual, SDI or NDI, NDI®, SRT, UDP. ST-2110). It renders the frames in realtime either on the host GPU (Graphics) or CPU (video file decoding) and should never be quit during playout operations.

...

  • Minimal User Interface & Preferences: Just Out allows for an effortless Channel setup while being configured and maintained from within Just Control. Just Out itself provides only a minimal user interface and the preferences needed to configure the basic properties of the engine.

  • Diagnostic Window: Displays engine statistics like the buffer status, master time, reference time, and the name of the clip which that is currently playing in the first Video layer. Three buttons provide access to the log files, allow you to save the current status of Just Out, and to reset the values shown in the diagnostic window.

  • Quit-Safe: You can quit the Just Connect and Just Control applications without stopping the actual playout. When doing so with quitting Just Out, the playout stops immediately. Therefore, Just Out does not allow to be closed using a keyboard shortcut. To quit Just Out, you have to explicitly confirm the termination of the current playout operation.

Preferences

After the installation, there are a few settings which that can be changed in the preferences of Just Out.

...

  1. Start Just Out.

  2. Open to the “Just OutOut” menu.

  3. Select Preferences…“Settings…”

  4. The “Just Out Preferences” window will appear.

...

Network TCP Port: This is the network TCP port used by Just Out when publishing its service over the network to Just Connect. By default, this is set to “5509” and must correspond to the port defined in the channel Channel it belongs to. It is possible to use any unused port between “1” and “65535”, in case that if port “5509” is already used on this machine.

Warning

A port is an a unique identifier for a service running on a computer. If you are not sure whether a port is available on your network or not, please consult your network administrator.

...

Timecode Source: Here you can define where Just Out takes the Master Timecode from. Currently, only You can choose between Computer (NTP) is available, more options will be available soonand LTC Audio sources.

Warning

When changing the preferences, you must restart Just Out for any changes to take effect. Restarting Just Out will stop the final output for the time of the restart. 

...

Just Out has no actual user interface, but only a DiagnosticDiagnostics window.

Diagnostics Window

Select the menu Window → Diagnostics. The “Just Out diagnostics Diagnostics” window shows:

  • The Status of the Activation and the Mode

  • The Channel Name

  • All Timecode relevant information like such as the Master Timecode source, the Master Timecode (with the difference to the Timecode source) as well as the amount of rundown information (in hours, minutes, and seconds) Just Out stores currently (up to 4 hours of playlist information (“Playlist Buffer”).

  • Playout Statistics like such as the current Video on air and the Output Device and Format

  • GPU Vendor, Model, and Driver.

  • And information about the Buffer, the Decoding, and the Render Time

  • Skipped frames

  • Resync frames

The buttons at the bottom can be used to show Engine Logs, Save Diagnostics (for support purposes), and to Reset the Statistics shown in the diagnostics window.

...

Usually Just Out buffers between 0.5 and 10 seconds of the uncompressed final output in the RAM to make sure the playout can continue without dropping frames even under bad conditions. Because Buffer values above 6 seconds can put some additional pressure onto on the system, the predefined values should only be changed after contacting your local ToolsOnAir partner, or the ToolsOnAir Support SystemTeam.

Bad Conditions

Bad Condition 1

Bad Condition 2

The storage system is not fast enough to deliver the required data. This could happen because…

  • The disk is getting full.

  • Heavy copying of files in progress.

  • Many users access the same storage system at the same time.

  • The file system is highly fragmented.

The GPU isn't able to render the content fast enough because the current Graphic is too complex.

In both cases, a buffer under run may occur and eventually Just Out will begin to drop Video frames.

...

If the Just Out buffer reaches a critical low state of 50% or less and stays there for more than 0.5 seconds, Just Out will automatically eject the most recently started Graphic. If this does not result in the buffer recovering to a non-critical state, then all non-infinite Graphics will be automatically ejected.

...

The buffer status is shown in Just Out's Diagnostics window. Before the buffer status reaches a critical level, the Auto Eject function steps in.

...

The buffer status is also shown in Just Connect...,

...

and in Just Control.

...

The buffer status is shown in the control area, where 0% means an empty buffer and 100% is a full buffer. The higher the value, the better.

Info

It is possible to change the sensitivity of the Auto Eject function. In case on air Graphics keep being ejected every time you change an attribute, please → contact us to get more information how the sensitivity can be adjusted.
