Learn how to manage and edit the video assets in Adobe Experience Manager (AEM) Assets. Also, if you are licensed to use Dynamic Media, see the Dynamic Media Video documentation.

Upload and Preview video assets

Adobe Experience Manager Assets generates previews for video assets with the extension MP4. If the format of the asset is not MP4, install the FFmpeg pack to generate a preview. FFmpeg creates video renditions of type OGG and MP4. You can preview these renditions in the AEM Assets user interface.

  1. In the Digital Assets folder or subfolders, navigate to the location where you want to add digital assets.

  2. To upload the asset, click or tap Create from the toolbar and then choose Files. Alternatively, drop it directly in the assets area. See Uploading assets for details around the upload operation.

  3. To preview a video in the Card view, click the Play button on the video asset.

    Video Preview

    You can pause or play video in the Card view only. The Play/Pause button is not available in the list view.

  4. To preview the video in the asset details page, click/tap the Edit icon on the card.

    The video plays in the native video player of the browser. You can play, pause, control the volume, and zoom the video to full screen.


Configuration to upload video assets that are larger than 2 GB

By default, the AEM Assets Touch UI does not let you upload any assets that are larger than 2 GB because of a file size limit. However, you can overwrite this limit by going into CRXDE Lite and creating a node under the /apps directory. The node must have the same node name, directory structure, and comparable node properties of order.


The AEM Classic user interface does not have a 2 GB file size limit restriction. Also, end-to-end workflow for large video is not fully supported.

To configure a higher file size limit, perform the following steps in the /apps directory.

  1. In AEM, tap Tools > General > CRXDE Lite.

  2. In CRXDE Lite, navigate to /libs/dam/gui/content/assets/jcr:content/actions/secondary/create/items/fileupload. To see the directory window, touch the >> icon.

  3. From the toolbar, tap the Overlay Node button. Alternatively, select Overlay Node from the context menu.

  4. In the Overlay Node dialog, tap OK.

  5. Refresh the browser. The overlay node /jcr_root/apps/dam/gui/content/assets/jcr:content/actions/secondary/create/items/fileupload is selected.

  6. In the Properties tab, enter the appropriate value in bytes to increase the size limit to the desired size. For example, enter the following value to increase the size limit to 30 GB:

    {sizeLimit : "32212254720"}

  7. From the toolbar, touch Save All.

  8. In AEM, tap Tools > Operations > Web Console.

  9. On the Adobe Experience Manager Web Console Bundles page, under the Name column of the table, locate and tap Adobe Granite Workflow External Process Job Handler.

  10. In the Adobe Granite Workflow External Process Job Handler page, set the seconds for both Default Timeout and Max Timeout fields to 18000 (five hours).

  11. Tap Save.

  12. In AEM, tap Tools > Workflow > Models.

  13. On the Workflow Models page, select Dynamic Media Encode Video, then tap Edit.

  14. On the workflow page, double-tap the Dynamic Media Video Service Process component.

  15. In the Step Properties dialog box, under the Common tab, expand Advanced Settings.

  16. In the Timeout field, specify a value of 18000, then tap OK to return to the Dynamic Media Encode Video workflow page.

  17. Near the top of the page, below the Dynamic Media Encode Video page title, tap Save.

Publish video assets

After your video assets are published, they are available to you for including in a web page by way of a URL or embedding on a web page.

See Publishing Assets.

Annotate video assets

  1. To display the asset details page, from the Assets console, click/tap the Edit icon on the asset card.

  2. To play the video, click/tap the Preview icon.

  3. To annotate the video, click the Annotate button. An annotation is added at the particular timepoint (frame) in the video.

    While annotating, you can draw on the canvas and include a comment with the drawing. Comments are automatically saved in Adobe Experience Manager Assets. 


    To exit the annotation wizard, click Close.

  4. To jump to a specific point in the video, specify the time in seconds in the text field and click Jump. For example, to skip the first 10 seconds of video, enter 20 in the text field.

  5. To view it in the timeline, click an annotation. To delete the annotation from the timeline, click Delete.
