Installing Accurate.Video

The component for Accurate.Video is installed by default, but can also be installed separately:

./setup --components=accurate_video

To enable the Accurate.Video plugin, either run the following commands:

/opt/cantemo/portal/ enable_portal_apps se.codemill.portal.av_core
systemctl restart

or go to the System Overview page in Cantemo, click the button to enable the plugin, and then restart Cantemo.

Upgrading Accurate.Video

The Accurate.Video component can be upgraded separately:

./setup --upgrade --components=accurate_video

Defaults in the Accurate.Video user interface settings (settings.js) and it’s Vidispine Adapter settings ( may change between versions. Use this command to apply latest defaults:

/opt/cantemo/portal/ accurate_video_settings --update-settings


This will overwrite any custom settings in both these files. The command will backup the old files and prints out the filenames so you can reapply custom changes.

Then finally use this to restart the new back-end version:

/opt/cantemo/portal/ accurate_video_settings --recreate-container

Accurate.Video Validate Settings

Accurate.Video applications use settings from /opt/cantemo/portal/portal/plugins/av_core/media/assets/json/settings.js. This file needs to be modified for customized setup.

The default setup shows non-timed metadata from the Film group, and uses the AvMarker metadata group for markers (SubClips in Cantemo).

The metadata field av_asset_status is used to store Status from Validate. It is reusable, meaning that the same field can be used in other metadata schemas.

Available status values are defined by assetStatus.statuses - the set of values in settings.js should match the choices defined for this field in Cantemo Metadata Manager.

Additionally other metadata fields from the groups AvAdBreak, AvAsset, AvEditTimeline are used by the applications.

forms.defaultAsset defines the non-timed metadata shown in Validate.

markers can be used to define custom marker tracks and their metadata.

render.presets defined what shape tags are available for rendering from Accurate.Video Edit.

Audio Waveforms - Analyze Jobs

Accurate.Video displays audio waveforms for video and audio media. The waveform data is created in Vidispine with an ANALYZE job.

Installing or upgrading Accurate.Video adds the following jobsteps to Vidispine to automatically get an audio waveform for video and audio items that are ingested to a system:

"AUTO_IMPORT" - step 401
"CONFORM" - step 401
"ESSENCE_VERSION" - step 753
"RAW_IMPORT" - step 653
"TRANSCODE" - step 201

If you run this ANALYZE job separately in your workflow you can delete these steps. These steps are also removed when the “Accurate.Video Plugin” is disabled from System Settings.

Media ingested before Accurate.Video was added to the system will not by default have waveforms. To generate them, there is a Rules Engine 3 script called that can be automatically triggered for example using a Saved Search rule.

Accurate.Video System Components

Accurate.Video on Cantemo contains two main components: 1) The front-end JavaScript application, which is served from Cantemo Nginx under /av/. 2) And a back-end component called Accurate Player Vidispine Adapter. It is a light-weight docker container that locally adapts Accurate.Video requests to Vidispine. The APIs from this container are also served by Cantemo Nginx, under the path /AVAPI/.

The container logging can be seen with the following command:

sudo docker logs accurate-player-adapter-vidispine -f

The container is setup using the accurate_video_settings management command, see Installing Accurate.Video.
