Video Overlay
Channel Shortcuts
Channel shortcuts are interactive video overlay elements in live view and playback, which allow you to switch to other (predefined) channels. These can be thought of as "portals" to other channels. A simple usage scenario is to place shortcuts on doors or street turns, so that users can track people as they move between the different camera views.
Shortcuts are configured in Macula Console and then are visible in the Macula Monitor application as colored rectangles overlaying the video. Single clicking them will instantly display the linked resource instead of the current channel. The shortcuts only work in live view and multichannel playback, and are invisible in other modes.
If the feature is not used, you can turn OFF the overlay visibility in the Macula Monitor application settings: this will disable the shortcut functionality. To do this, go to the Macula Monitor main menu Edit > Application settings > Viewport overlays > Video overlays section and select the Always OFF option.
Timestamp Overlay
You can enable timestamp overlay over the viewport. To do so, go to Macula Monitor main menu -> Edit -> Application settings ->Viewport overlays -> Timestamp, and select an option you prefer.
Text Overlay From Data Sources
If the connected server has data sources configured and these are associated with video channels, the received textual data are displayed in Macula Monitor application embedded with the video in the live view and in the instant and regular archive playback, and it is also possible to search through the recorded text.
Live View
Textual data from the associated external data source will appear embedded with the live video stream. This happens automatically and you do not have to do anything else in Macula Monitor to enable the video overlay.
Text layout is configured via Macula Console application for each channel.
Playback
The same functionality is available in the instant playback and regular archive playback modes, if the data stream is set to be recorded with the target channel's video. The data stream is marked on the timeline as dark green line. Note that the data stream is not displayed in the smart search and sequence explorer modes.
For data-only channels, advanced search is available.
Video Export
Textual data can be exported with the video clips, embedded as hard subtitles. In order to do this, you need to export your desired video file:
as AVI with the JPEG compression
in MKV format using VP8 compression, with hard subtitles and external data enabled
making sure that you have the Include external data option enabled.
