Playout v.5 Important Notes

Customers using an INTEL-based Mac who would like to use macOS 14 Sonoma

Playout of realtime GFX templates may encouter failure, due to an inconsistency in macOS Sonoma. We recommend that all customers who utilize an INTEL-based Mac and realtime GFX continue to utilize macOS 13.6.x Ventura until Apple resolves the issue.

Customers using an INTEL-based Mac who would like to use SRT or UDP streaming out

We recommend all customers using an INTEL-based Mac to reduce the data rate used for the H.264 compression to 1500kbps or less. Using a higher data rate will result in dropped frames and an automated restart of the Just Out application, once too many frames have been dropped.

General Notes

Before upgrading to v.5.x of our playout applications, please be aware of the following changes.

  • All customers using v4.x or lower - a new activation code is needed to use v.5 of just:live and just:play.

  • The MacMini6,x and MacMini7,x are not supported any more, and we strongly recommend all customers using such a Mac mini model to update to a new Apple silicon-based Mac mini M1 (Macmini9,1) or Mac mini M2 (Mac14,3, Mac14,12 (M2 Pro)).

  • There are new documents available for version 5, and we recommend all new and existing customers updating from a previous version to consult the new user guides.

We kindly request that all users upgrading from a previous version adhere to our update guide, which can be found here:

For Customers Updating from previous versions to v.5.x

All customers upgrading from a previous version require a new v.5 activation code to be able to play out using Just Out without a watermark applied on the SDI, NDI®, SRT, UDP or ST-2110 output.

Customers using TeamViewer to access the Mac running Just Out

If you’re planning to use TeamViewer to access a machine running Just Out, please verify that you have the following settings deactivated in the “Remote control” panel of the TeamViewer client (the machine you use to connect to the machine running Just Out).

Failing to do so will switch the audio output away from the video device at the same time you connect to the machine running Just Out using TeamViewer.

Specific features that were available in Version 2.x are no longer available in Version 3 and higher. The comparison table below shows some of the features that may become available again in future releases, while others had to be removed permanently.

Codecs and Container Formats supported

Due to macOS changes, we cannot support legacy codecs and container formats any more.

Container Formats not available using v.3 and higher: .3gp, .avi, .dv, .f4v, .mkv, .mpegts
Codecs not available using v.3 and higher: Apple Animation (.mov)

If you rely on these codecs, please keep using v.2.x (or a previous version) and contact us. Some codecs/containers can also be added to the system by installing Apple's Pro Video Formats. Please find more information about Codecs and Containers in section 2.4 Supported Video Containers & Video Codecs (v.5.0) and how to install support for additional Containers and Codecs using the Apple Pro Video Formats.

Using v.2.x Channels in v.5.x

When updating from version 2.x, we strongly recommend backing up existing channel(s) using the backup feature of Just Connect (see Advanced Settings) or by copying the channel from /Library/Application Support/ ToolsOnAir/Just Connect to an external storage, before performing the update.

Please → contact ToolsOnAir in case you have any questions regarding the migration from v.2.x to v.5.x.

Renamed User Interface Application

With v.3.x we introduced a unified control application for all ToolsOnAir applications called Just Control. During the setup, the administrator can define which one of the two available solutions/user interfaces, namely just:live or just:play should be used for a specific channel.

Poster Frames in v.5.x

In version 5.x, the Poster Frames are generated compressed, as it was the case in version 2.x. Even so, please make sure to save them on a fast and big storage, that is not the same storage you use as the repository of your movies. The internal SSD or another fast internal disk is perfect for storing Poster Frames.

SMB issues using some versions of macOS

We have experienced performance issues with shared storage connections using older versions of the SMB protocol. If you encounter such issues, please contact your storage provider for assistance. Alternatively, you might try using the following macOS Terminal commands, on all Macs running TOA software, to disable the SMB 1 protocol, which may improve the faulty behaviour:

echo "[default]" | sudo tee -a /etc/nsmb.conf

echo "protocol_vers_map=6" | sudo tee -a /etc/nsmb.conf

For Customers with more than 5,000 Video files in a single Folder

Whenever a video file is added/removed or changed, the content of the whole folder has to be scanned to update the Library. During our tests, we have observed that this can take a few seconds when there are more than 5,000 files in a folder. Because of this, we recommend limiting the amount of video files in a single folder to a maximum of 5,000.
