Video & Snapshot Export
Video clips, frame sequences, multichannel layouts and individual pictures can be exported in order to be viewed later without help of Macula software.
Snapshots Export
A snapshot of an individual channel can be taken at any time from live view, sequence explorer, instant playback and regular playback modes. To save a snapshot, click the Snapshot 
button in the overlay controls or bottom panel controls. If you have pre-defined the snapshot export settings in the application settings, the frame will be saved immediately; otherwise, a dialog box will pop up, prompting you to specify the save parameters. Please check the topic on application settings for detailed description of each parameter.
If the picture was dewarped or zoomed in using DPTZ, the snapshot will contain the target region.
If the channel has video analytics configured, all currently displayed visual elements will be exported with the snapshot. To change VA element visibility in Monitor, go to the Application settings and change the VCA settings in the Video overlays tab. All elements that have the Always On and On if selected settings will be embedded into the snapshot, while elements that have the Always off setting will not be exported.
In playback mode, it is possible to export a snapshot that will consist of all channels present in the current layout. To do this, use the Multichannel Snapshot 
button in the right side of the bottom panel. The resolution of the combined frame is 3840x2160px.
The frames will be saved with your pre-defined frame export settings, if this option is enabled in the Application settings; otherwise, you will be prompted to specify the file name and quality preference. After you have clicked the snapshot or multichannel snapshot button, the frame will be automatically saved in JPG format and will appear in the Library section of Macula Monitor.
Snapshots can be also saved as PDF reports. For this, enable the corresponding setting in the snapshot export profile. When the report is ready, you will see it in the Library section.
Video Export
Video export settings can be pre-defined in the Macula Monitor Application settings. These include: file name, output format, compression and resolution preferences, as well as subtitle settings. Some of the settings, when selected, allow additional features like motion blur.
You can choose to use the pre-defined settings always; otherwise, you will need to confirm or adjust the export settings every time you export a video clip from anywhere. All the exported fragments will be displayed in the Library immediately.
Video can be exported automatically (without additional time range prompt) by clicking the Video Export 
button in the viewport overlay controls:
from Sequence Explorer, by selecting a range of at least two video fragments: selected clips will be exported
from the Instant Playback mode: the most recent currently loaded footage will be exported at once (last 5 minutes, by default).
from the Smart Search mode, by selecting the desired search result: selected fragment will be exported
A video export dialog box with additional settings can be launched in the following ways:
from Playback mode, by clicking the Video Export button in the bottom right panel (the channel choice is limited to those that are currently displayed plus multichannel export)
from Sequence mode, by clicking the Video Export button in the centre on the bottom panel (channel choice is limited to channels currently being viewed)
When exporting from Playback with advanced options, you will have an opportunity to choose the stream to be exported (from the channels currently present in the layout) or, alternatively, choose to export the clip with all the displayed streams (multichannel export); also, you can combine any video stream with any audio stream (also coming from one of the displayed channels).
In playback mode, it is possible to export a video clip that will consist of all channels present in the current layout. The maximum resolution of the combined frame is set up via application settings (main menu Edit > Settings > Video export). Default limitation is 2MP (1080p).
In Sequence mode, stream selection is reduced to the sequenced one and you can choose whether or not you wish to export the associated audio stream, too. In both modes, you can specify the date and time range for the exported video clip.
Select your desired date and time boundaries for the export of the footage: dates can be picked from the drop-down calendars, times can be adjusted by clicking hours/minutes/seconds and then scrolling up/down with mouse wheel. When you are ready, click the Export button; the video file will be saved with your pre-defined video export settings, if enabled; otherwise, you will be prompted to specify the stream properties and export directory.
Motion Blur
Exporting video clips with MKV+VP8 settings gives you an extra option to apply privacy masking to the video. The video is retrospectively scanned for motion (software-side MD is applied) and the selected regions are blurred, thus hiding whatever is behind the motion. First, enable the feature in the video export settings, and then an additional dialog box will pop up every time you export a video clip.
To enable privacy masking, choose the following settings for video export:
Video output file type: MKV
Video compression: VP8
Motion blur: enabled (checkbox)
Next time you export a video clip, you will be asked if you wish to proceed with motion blur. Click Yes to open the dialog box and adjust blur settings, or click No to export this video clip without any masking.
On the right side, choose the settings you find appropriate:
Grid size: motion grid dimensions for both region selection and motion processing, can be 16x16, 32x32, or 64x64 (larger grid size corresponds to smaller grid elements)
Intensity: blur level, ranging from very low (minimum blurring) to very high (heavy blurring)
Motion sensitivity: detector intolerance to changes, ranging from very low (small fluctuations will be ignored) to very high (smallest changes will trigger MD)
Then, draw detection areas over the preview image. Simply select the area type and mark the desired grid cells according to the required masking levels:
no blur (transparent, no colour)
blur always, regardless of motion presence/absence (red area)
motion blur with specified sensitivity (blue area)
By default, when the blur dialog box is opened, the whole image is marked blue, which stands for motion blur only. Draw over with a different colour to change the detection type.
When ready, click Apply and export: your video clip will be then exported with the blurring effect. Depending on the selected blur settings and video clip size, this make take some time: the selected part of the video stream will be analysed for motion, meaning that the existing motion data, if present, are ignored. This also means that privacy masking can be applied to any video stream, even if there are no motion data present in the archive.
If you wish to discard blurring but still want the video clip to be exported, select Skip blurring: the video will be then exported immediately, without privacy masking. Finally, if you have changed your mind and no longer wish to export the video, click Cancel export to simply close the dialog box.
