Dynamic Media layout container disappears in edit mode after refresh in AEMaaCS

Last update: Mon Dec 29 2025 00:00:00 GMT+0000 (Coordinated Universal Time)

When working with Dynamic Media core components for video authoring in Adobe Experience Manager as a Cloud Service (AEMaaCS), the layout container disappears from the page in edit mode after a refresh. This prevents the video from rendering and makes it impossible to replace or interact with the component. To resolve the issue, sync and activate required presets, CSS, and artwork.

Description description

Environment

Adobe Experience Manager as a Cloud Service (AEMaaCS) – Sites

Issue/Symptoms

  • After adding a video using the Dynamic Media core component with an overlay, the video displays correctly at first.
  • Upon refreshing the page in edit mode, the Dynamic Media layout container disappears.
  • The video doesn’t render and cannot be replaced or interacted with in edit mode.
  • The issue doesn’t occur in preview or publish modes; videos display correctly there.
  • A 404 error appears for a URL related to viewer presets, such as Video_social.

Resolution resolution

Follow these steps to resolve the issue:

  1. Open the Sample Manager on the AEM Author at https://<your-author-host>/libs/dam/gui/content/s7dam/samplemanager/samplemanager.html.

  2. Re-sync Dynamic Media sample assets (presets, CSS, artwork) by running the available actions in Sample Manager.

  3. Select Trigger DM Setup Async Job on the Sample Manager page to run the Dynamic Media Setup Async Job and re-sync viewer artwork and CSS to Scene7.

  4. Trigger the Dynamic Media Setup Async Job from Sample Manager and confirm the job completes successfully.

  5. Verify your Dynamic Media Cloud Service configuration:

    • Check that the Secure Preview Server and company details are correct.
    • Confirm that your AEM Author instance’s public IP address is whitelisted in Scene7.

  6. Refresh the page in edit mode and confirm that the video appears correctly.

Note: If the required viewer presets or sample assets aren’t fully synced or published to Dynamic Media (Scene7), authoring issues such as disappearing containers may occur due to missing configuration files.
