Visual Data Curation

​
Filter and Sort

Some basic filers are available always available, but more advanced filters must be calculated by upgrading your folder and computing metrics & embeddings. See Compute Metrics & Embeddings for details.
You can refine searches by with quality metrics, Collections, custom metadata, folders, data titles, and data types. Collections: Collections are a way to save interesting groups of data units and labels, to support and guide your downstream workflow. Custom Metadata: Custom metadata added to data units. The custom metadata added to data units in Folders persists to Annotate Projects and Active.
For information on importing custom metadata, refer to Adding Metadata in the documentation.
Data title: The file name of the image or video. Data Types: Data, labels, and Predictions can be filtered by: images, image sequences, image groups, and videos. File ID: The unique hash assigned to the image or video when it imports into Encord. Folder: The Folder images or videos reside in. Integration: The integration (if any) your images/videos reside in. Keyframe: Frames of interest you specified on your videos. MIME type: Also known as media type. The file type of an image or video. For example, video/mp4. Storage location: The location where your images/videos reside. Examples include AWS, GCP, Local. Uploaded at: The date and time that the image/video uploaded. To filter data:
  1. Navigate to Data > Explore and select a folder.
  2. Click the Filter dropdown or press F. Index Filtering
  3. Add and configure the filters you need.
  4. Click Search to update the results.

​
Preset Filters

Presets are only available to customers with the Curation package.
Preset filters let you save and reuse filtering criteria across your workspace. Since presets are available everywhere during data curation, some may return no results in certain contexts. For example, a preset scoped to Folder A will return nothing when browsing Folder B if Folder A isn’t a subfolder of it. To create a Preset filter:
  1. Navigate to Data > Explore and select a folder.
  2. Click the Filter dropdown or press F.
  3. Add and configure the filters you need. Index Filtering
  4. Click +Create preset and give the preset a name.
  5. Click Create to finish creating the preset. Create Presets
To use an existing Preset:
  1. Navigate to Data > Explore and select a folder.
  2. Click the Filter dropdown or press F.
  3. Select the Preset you want to use from the dropdown. All presets are listed at the top of the list oif filters.
  4. Click Search to update the results.
Global filters apply to any Folder, but Local filters only apply on the Folder where the Preset was created.

​
Sorting

Sort your data, in ascending or descending order, using filters and quality metrics. To sort your data:
  1. Navigate to Data > Explore and select a folder.
  2. Select the metric to sort the data. Index Sort
  3. Specify ascending or descending order.
  • Filter and use the natural language searches to further help get the results you want.
  • After filtering, sorting, and searching, create a Collection.

​
Quality Metrics

Quality Metrics are only available to customers with the Curation package.
Quality metrics are only calculated when you upgrade your folder or calculate metrics & embeddings
Quality metrics evaluate your data, labels, and model predictions, forming the foundation of effective data curation. They provide meaningful ways to surface, rank, and explore your data — helping you identify issues, spot patterns, and make informed decisions about what to curate, fix, or prioritize.
If you add a large amount of new data to a folder, existing uniqueness and diversity scores may no longer reflect the full dataset. You can recompute these metrics at any time to bring them up to date.
Video Quality Metrics: Video quality metrics must be calculated by upgrading your folder. Examples include Area, Clip duration, Frames per second, Number of frames. Frame Quality Metrics: Frame quality metrics must be calculated by upgrading your folder. Examples include Area, Frame number, Random value.
Label Quality Metrics are used for sorting data, filtering data, and data analytics.
Model quality metrics help you evaluate your data and labels based on a trained model and imported model predictions.Acquisition FunctionsAcquisition functions are a special type of model quality metric, primarily used in active learning to score data samples according to how informative they are for the model, enabling smart labeling of unannotated data.
Natural language search and similarity search can only be performed after you upgrade your folder or calculate metrics & embeddings.
To use natural language or image search:
  1. Navigate to Data > Explore and select a folder.
  2. Type a search query or upload an image.
Natural Language Search

​
Collections

Collections are only available to customers with the Curation package.
Collections are saved groups of data units or labels that let you curate subsets of your data and perform bulk actions on them, such as sending items to annotation, running bulk classifications, or exporting a curated Dataset. In the Explorer filter toolbar, each collection has a … (three-dot) menu that displays the collection name and its unique collection ID. Click the copy icon next to the ID to copy it to your clipboard — useful for API calls, support requests, or cross-referencing collections. Actions in this menu are organized into logical groups (navigate, manage, data, workflow, and danger) separated by dividers, making it faster to locate the right action. Empty groups are hidden automatically so no stray dividers appear.

​
Video Curation

You have to compute Metrics and Embeddings for your videos before you can explore them in Data > Explore or Project > Explore. See Compute Metrics & Embeddings for details.
Use the Video tab in Data > Explore or Project > Explore to natively view all the videos available in your Folder or Project. From the Video tab you can sort and filter all of your videos based on Video Quality Metrics and apply video frame level metrics.
Video frames are sampled for metric and embedding calculation at 1 FPS starting from the first frame. Using keyframes and custom metadata you can specify the frames you want imported. Contact us to discuss changing the sampling frame rate how to indicate specific frames.

​
Filter and Sort Videos

You can filter and sort video frames the same way you filter and sort images. See Filter and Sort Images for details.
Each unexpanded video appears as a compact card showing a thumbnail, its duration, and its sort metric.
  • Hover to preview: Hovering over a card automatically plays a muted, looping preview of the video, so you can screen footage without opening it. Labels are not currently overlaid on this preview.
  • Select a video: Hover over a card to reveal a selection checkbox, along with quick actions such as similarity search.
  • Expand a video: Click + N frames on a card to expand that video in place into a full-width frame-strip row. The row appears at the video’s current sort position, and the other cards flow around it.
Collections are shown on video cards. Selecting and adding videos to a Collection selects the whole video, not individual frames.

​
Inspect Video Frames

Expanding a video replaces its card with a full-width row showing its sampled frames. The row header consolidates the controls previously spread across the view:
  • A frame-metric selector, for sorting or coloring frames by a specific quality metric.
  • The Show only Keyframes toggle — see Keyframes.
  • An Analytics button that opens a frame-level analytics chart. This requires the explore_analytics feature to be enabled on your organization.
  • A Collapse (or Hide frames) button that folds the video back into the card grid. Collapsing a video also closes its analytics chart.
The frame-offset slider used to move through a video’s frames only appears once that video is expanded.
To have every video expanded by default instead of browsing the card grid first, enable Load video frames by default in the Display panel.

​
Display Settings for Videos

Click Display to configure how video cards appear in the grid:
  • Card details: Choose the title, Collections, and selected metric shown on each video card, the same Card details control used for other data types.
  • Grid density: The grid-count slider controls the height of an expanded video’s frame-strip row. It does not change the width of unexpanded video cards, which stays fixed.
