  </Accordion>
</AccordionGroup>

## Projects

<AccordionGroup>
  <Accordion title="I accidentally removed all users from a Project. How can I find the Project?">
    As a Workspace admin you can search for any Project, including those without any collaborators, in the section [showing all the Projects in your Workspace](https://docs.encord.com/platform-documentation/Annotate/annotate-projects/annotate-manage-annotation-projects#join-projects-in-your-workspace).
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title=" How do I manage teams, or create user groups?">
    You can create user groups within your organization. These can be added to specific Projects as teams.

    * Documentation on user groups can be found [here](/platform-documentation/General/general-workspace-settings#creating-user-groups).

    * For information on how to create teams for a given Project see the [Team Management section](/platform-documentation/Annotate/annotate-gettingstarted/curation-management-annotation#4-team-management) in our documentation.
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title="What does the 'This is being edited' pop-up in the label editor mean">
    Don't worry, no data has been lost! This is a warning from our system (known as the "editor lock") it occurs when:

    * Two different people are editing a task at the same time.
    * Or, that one individual has the task open in two different tabs, or browser windows.

    In both cases we recommend to click 'cancel' to prevent any unexpected data overwrites.

    See [our documentation here](/platform-documentation/Annotate/annotate-label-editor#editor-lock) for more details.
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title=" Why is there a warning sign next to my Project where it's listed">
    A warning symbol is displayed when a project is too large - meaning it contains too much data. When selecting the project you should encounter the following message:

    > ⚠️
    > "This project has exceeded the recommended number of tasks. To avoid performance issues, you need Admin access to manage and reduce the amount of data in this project".

    The diagram below illustrates the steps you should take to fix the issue.

  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title=" Large audio files take a long time to load in the Label Editor. What can I do?">
    <Note>
      Apply this solution when your audio files are stored in a cloud storage bucket.
    </Note>

    Create a JSON file with your waveform data and add the JSON file to the folder with your audio file. Learn how to do that [here](/platform-documentation/Curate/index-audio#long-audio-files).
  </Accordion>
</AccordionGroup>

## Datasets

<AccordionGroup>
  <Accordion title=" What's the difference between image groups, and image sequences?">
    Both image groups and image sequences are file types you can create in Encord to make labeling your images easier and more efficient. Both are created by taking multiple single images as an input, and compressing these into a single data unit. The difference lies in the resulting data unit.

    * Image groups can contain images of varying orientations and are best thought of as a collection of images.
    * Image sequences can only contain images of the same orientation - which allows them to be treated the same way that videos are in which each input image constitutes a single frame of the resulting image sequence.

    See our [documentation here](/platform-documentation/General/general-supported-data#image-groups) for more details.
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title=" How do I upload DICOM data? ">
    How to upload you DICOM data depends on whether you plan on using files stored in a private cloud, or locally.

    * Local files can be dragged-and-dropped when [creating a new Dataset](/platform-documentation/Annotate/annotate-datasets/annotate-datasets#creating-datasets).
    * Files from your private cloud are uploaded using [JSON files](/platform-documentation/Curate/add-files/index-register-cloud-data#json-format). We do not support upload via the CSV file format.

    For information on uploading your DICOM files using the Encord SDK, see the relevant documentation [here](/sdk-documentation/getting-started-sdk/sdk-register-data-aws).
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title="How do I update client metadata?">
    Client metadata can be updated by including the `"upsert_metadata": true` flag in the upload JSON file. An example JSON file is provided [here](/platform-documentation/Curate/add-files/index-register-cloud-data#update-client-metadata).
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title=" If I have duplicate Datasets, how can I find out which one is which? ">
    1. Navigate to *Datasets* on our platform from [https://app.encord.com](https://app.encord.com) or [https://app.us.encord.com](https://app.us.encord.com).
    2. Re-name both datasets to make them distinguishable.
    3. Open up both cases in the editor, and see which one is which (e.g. which one is annotated and which is not).

    <Note>For information on how to delete a dataset see our documentation [here](/platform-documentation/Annotate/annotate-datasets/annotate-datasets#danger-zone-deleting-datasets).</Note>
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title="How do I make sure my videos load quickly?">
    1. An annotator’s download speed from private cloud storage has to be at least 3-4 times the video bitrate.
    2. Make sure the videos have enough keyframes for smooth frame-by-frame navigation (roughly every 50 frames for high-resolution videos).
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title=" How do I re-encode videos? ">
    <Note>Re-encoding is only available to Enterprise customers. Contact [sales@encord.com](mailto:sales@encord.com) for more information. </Note>

    See the [re-encoding data](/platform-documentation/General/general-supported-data#re-encode-videos) section in our documentation for more information.
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title=" What video formats are supported? ">
    We support the following formats and codecs:

    * **`.mp4` with `H.264`** – We recommend using H.264 as the default codec, unless you have specific requirements that necessitate H.265. H.265 may present compatibility issues in some cases.
    * **`.mp4` with `VP9`**.

    Visit our [documentation on compatibility](/platform-documentation/General/general-supported-data) for more information on data compatibility.
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title=" I am getting an error when I try to display video or DICOM files. How can I fix this? ">
    This could be browser issue. To resolve:

    1. Ensure you are using the Chrome browser.
    2. [Turn hardware acceleration off](https://www.howtogeek.com/412738/how-to-turn-hardware-acceleration-on-and-off-in-chrome/).
    3. If you are still stuck, contact [support@encord.com](mailto:support@encord.com) for assistance.

## Label Editor

<AccordionGroup>
  <Accordion title=" Why can't I see all classifications/annotations when reviewing? ">
    Check the [sampling rate](/platform-documentation/Annotate/annotate-projects/annotate-manage-annotation-projects#sampling-rate).

    It's possible that you are seeing a different number of classifications/annotations than expected because you have the sampling rate set too high/low.
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title=" What is causing the error I'm seeing in the Label Editor? ">
    There might be several possible causes if you see a "Something Went Wrong" error message in the Label Editor:

    1. CORS issues - when rendering an image or video from remote storage solutions (AWS S3, GCP, Azure) it is important to set up a valid Cross-Origin Request Sharing (CORS) Policy and failure to do so will result in errors when trying to load that remote content in the Encord application.

    To resolve these, check that a valid CORS policy is applied to the remote storage bucket, which allows Encord's domains. This varies between providers. For AWS the corresponding JSON looks like this:

    <CodeGroup>
      ```json Global theme={"dark"}
      [
          {
              "AllowedHeaders": [
                  "*"
              ],
              "AllowedMethods": [
                  "GET",
                  "PUT"
              ],
              "AllowedOrigins": [
                  "https://app.encord.com",
                  "https://api.encord.com"
              ],
              "ExposeHeaders": []
          }
      ]
      ```

      ```json US theme={"dark"}
      [
          {
              "AllowedHeaders": [
                  "*"
              ],
              "AllowedMethods": [
                  "GET",
                  "PUT"
              ],
              "AllowedOrigins": [
                  "https://app.us.encord.com",
                  "https://api.us.encord.com"
              ],
              "ExposeHeaders": []
          }
      ]
      ```
    </CodeGroup>

    2. Connectivity issues - Check that your local connection is fast and performant. We also recommend that, when configuring your remote storage, you choose a location geographically proximate to your annotators to ensure the smoothest loading experience.
    3. Occasionally, you might notice an error loading from remote storage if the remote storage bucket itself is newly provisioned. This is because the cloud provider sometimes provisions in any region first (to improve provisioning speed) then moves it to the requested region afterwards. If the issue is not resolver after \~1hr, contact Encord support.
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title="Why is the Label Editor crashing, and what can I do about it?">
    If the Label Editor crashes after attempting to load your cloud data file, it is likely that the signed URL is expiring. Refreshing the Label Editor re-signs the URL.

    We recommend [increasing the expiration time for signed URLs on your integration](/platform-documentation/General/annotate-data-integrations#edit-custom-signed-url-expiration-times).

# Data Curation & Label Validation

<AccordionGroup>
  <Accordion title="What is a quality metric?">
    A quality metric is a function that can be applied to your data, labels, and model predictions to assess their quality and rank them accordingly.

    Encord uses these metrics to analyze and decompose your data, labels, and predictions.
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title="How do I use Encord for active learning?">
    Encord supports the active learning process by allowing you to

    1. Explore your data to select what to label next
    2. Employ acquisition functions to automatically select what to label next
    3. Find label errors that potentially harm your model performance
    4. Sending data to Encord's Annotation module for labeling
    5. Automatically decompose your model performance to help you determine where to put your focus for the next model iteration
    6. Tag subsets of data to set aside test sets for specific edge cases for which you want to maintain your model performance between each production model
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title="How do I import my model predictions?">
    Encord supports importing predictions in the following ways:

    * [Use the Encord UI](/platform-documentation/Validation/active-how-to/active-import-model-predictions-cloud) to import your model predictions.

    * [Use the Encord API](/sdk-documentation/api-active/active-api-import-model-predictions-cloud) to import your model predictions.
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title="How can I do dataset management with Encord?">
    [Use Collections](/platform-documentation/Curate/curation-basics) in your Projects to handle all your Project data (not just Dataset) needs.

    Once you've created a Collection, you can send the Collection to Annotate in the following ways:

    * Apply the Collection directly to your existing Annotate Projects

    * Create a new Dataset and attached Annotate Project off of your Collection

    * Apply classifications to all frames/images in your Collections directly to your existing Annotate Projects
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title="How do I version my data and labels through Encord Active?">
    While you can version your data and labels using Active, Annotate supports [data versioning](/platform-documentation/Annotate/annotate-projects/annotate-manage-annotation-projects#save-label-version) and [label versioning](/platform-documentation/Annotate/annotate-projects/annotate-manage-annotation-projects#saved-versions).

    You can use [Collections](/platform-documentation/Curate/curation-basics) to version your Projects using Active.
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title="Does data stay within my local environment/cloud?">
    **Yes!**

    If your data is stored in cloud storage (AWS, GCP, Azure, OTC), your data remains there.
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title="What should I do if I encounter an error?">
    If you come across an error, don't worry! We're here to assist you.
    Reach out to [support@encord.com](mailto:support@encord.com), and we'll promptly address your concern.

    Additionally, we'd greatly appreciate it if you could [report the issue](https://github.com/encord-team/encord-active/issues/new/choose) on GitHub. Your feedback and bug reports help us improve Encord Active for everyone.

## Ontologies

<AccordionGroup>
  <Accordion title=" Can I re-order an Ontology? ">
    <Note>Re-ordering an Ontology is only possible using the SDK. We are looking to add a more user-friendly version of this functionality into our UI in the future.</Note>

    The following example is used to re-order the first two objects, and attributes in an existing Ontology using the SDK. Pass the `<ontology_hash>` into the `user_client`'s `get_ontology` method, perform the relevant changes, and call `ontology.save()` to commit the changes:

    ```python theme={"dark"}
    # Import dependencies
    from encord import EncordUserClient

    # Authenticate with Encord using the path to your private key
    user_client = EncordUserClient.create_with_ssh_private_key(
        ssh_private_key_path="<private_key_path>"
        )


    ontology = user_client.get_ontology("<ontology_hash>")

    # Re-arrange first and second objects in the Ontology.
    first_object = ontology.structure.objects[0]
    second_object = ontology.structure.objects[1]

    ontology.structure.objects[0] = second_object
    ontology.structure.objects[1] = first_object

    #Re-arrange attributes in the Ontology 
    first_att = ontology.structure.objects[0].attributes[0]
    second_att = ontology.structure.objects[0].attributes[1]

    ontology.structure.objects[0].attributes[1] = first_att  
    ontology.structure.objects[0].attributes[0] = second_att

    ontology.save()
    ```
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title="Can I add images to descriptions to help my annotators create more accurate labels?">
    You cannot add images directly to an Ontology's descriptions. Instead, reference images to help annotators can be added to the [annotation instructions](/platform-documentation/Annotate/annotate-projects/annotate-project-settings#upload-annotation-instructions).
  </Accordion>
</AccordionGroup>

## Cloud Integrations

<AccordionGroup>
  <Accordion title=" How do I set up an integration with Azure?">
    There are two methods to set up an Azure integration.

    1. By generating an account-level shared access signature (SAS).
    2. By using a service principal. Your user needs to be the admin of your Azure tenants for this method.

    Both methods are described in detail in our documentation [here](/platform-documentation/General/annotate-data-integrations/annotate-azure-blob-integration)
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title=" Can I use special characters in AWS S3 object names when importing data? ">
    The use of special characters in object names should generally be avoided.

    See the AWS docs [here](https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-keys.html) for more information.
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title=" Can I set up download via internet URLs? ">
    In the interest of keeping your data secure we do not offer downloading via internet URLs.
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title=" Why does my video buffer when I skip to a cached frame? ">
    A video needing to fetch data even though it has buffered implies that your AWS objects do not have caching enabled.

    When [setting up a permission policy for your AWS bucket](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/Expiration.html#ExpirationAddingHeadersInS3) ensure that all AWS objects used in Encord have the 'S3 standard' [storage class](https://aws.amazon.com/s3/storage-classes/).
  </Accordion>
</AccordionGroup>

## Buffering issues

<AccordionGroup>
  <Accordion title=" How can I fix buffering issues in the editor?">
    See our [documentation here](/platform-documentation/General/annotate-data-integrations#fix-buffering-issues) on tips to fixing buffering issues.
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title=" Why does my video buffer when I skip to a cached frame? ">
    A video needing to fetch data even though it has buffered implies that your AWS objects do not have caching enabled.

    When [setting up a permission policy for your AWS bucket](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/Expiration.html#ExpirationAddingHeadersInS3) ensure that all AWS objects used in Encord have the 'S3 standard' [storage class](https://aws.amazon.com/s3/storage-classes/).

  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title="How do I avoid hitting the timeout when using the get_project() method on the API?">
    Increase the [timeout](/sdk-documentation/general-sdk/network-configurations-sdk) of your Encord client, given the size of the project this is a long-running query.
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title=" Can I pre-select frames to label for a video using the SDK? ">
    Yes, you can!

    To do so, add an extra feature in the Ontology naming it, for example: `Selected` -> `Yes`.

    Share the ontology tree with Encord Support [support@encord.com](mailto:support@encord.com) to allow us to match the import script with the feature uuid (`featureNodeHash`).
  </Accordion>
</AccordionGroup>

<AccordionGroup>
  <Accordion title=" Can I import models and model predictions? ">
    You cannot upload your own model - but you are able to import your model predictions using the [SDK](/sdk-documentation/sdk-labels/sdk-import-labels-annotations-visual).
  </Accordion>
