Fix Embedded Movies Not Playing in Adobe Acrobat PDF eBooks
Question details
Embedded movies and videos in a PDF eBook fail to play in Adobe Acrobat, which repeatedly prompts for a Flash Player update despite the software appearing up to date.

- Product
- Adobe Acrobat / PDF
- Device & OS
- not provided
- Scenario
- Attempting to play embedded multimedia content within a downloaded or locally saved PDF eBook.
- Observed behavior
- Acrobat refuses to play the video and gets stuck in an update loop, continuously requesting a newer installation of Flash Player.
Verify if the PDF eBook contains legacy Rich Media annotations dependent on Adobe Flash Player, which officially reached its end of life in December 2020 and is no longer supported by modern software.
Update the PDF to Use Modern Video Formats
Since Adobe Flash is discontinued, the best long-term solution is to replace legacy embedded media with modern HTML5-based links or natively supported H.264 video formats.
Adobe Acrobat and modern operating systems have entirely dropped support for Flash Player. Any PDF created using legacy Flash-based multimedia tools will trigger update loops or fail to play completely.
To permanently resolve this issue, the eBook needs to be recreated using current multimedia standards.
Open the original source file (such as the Microsoft Word or Adobe InDesign document) that was used to create the PDF eBook.
Find and delete the old embedded Flash (SWF) video objects from the document.
Add the video back using a modern standard. The most reliable method is to insert a hyperlink directing readers to an externally hosted video on platforms like YouTube or Vimeo.
Save or export the updated document as a new PDF file and open it in your PDF reader to verify the links work properly.

Open the PDF Using a Legacy Environment
If you cannot access the original source file to recreate the eBook, your only workaround is to view the file on an older, isolated system that still supports Flash.
Create and Edit Multimedia PDFs with WPS Office
Bypass legacy Flash dependency issues by using WPS Office to edit your PDF documents. WPS PDF allows you to easily add secure hyperlinks to modern streaming videos and manage your document workflows smoothly without relying on outdated media players.
- 1. Open your PDF: Launch WPS Office and open the PDF file you wish to modify.
- 2. Access the Edit Tools: Click on the 'Edit' tab located on the top navigation ribbon.
- 3. Add a Link: Select the 'Link' option, highlight the text or image area for your video, and insert the URL to your modern hosted media.
- 4. Save the Document: Save your updated PDF. The video can now be safely accessed via standard web browsers across all modern devices.

Frequently Asked Questions
Why does Acrobat keep asking for a Flash Player update?
Adobe officially discontinued Flash Player in December 2020. Acrobat can no longer process legacy Flash-based media embedded in older PDFs, causing it to incorrectly loop a prompt for a software update that no longer exists.
Can I still play Flash-based videos in modern PDF readers?
No. All modern PDF readers, including the latest versions of Adobe Acrobat and standard web browsers, have actively removed support for Flash. The media must be recreated and embedded as an MP4 or linked to an external host.
What is the best video format to embed in a PDF eBook?
For native embedding, H.264 MP4 is the most widely supported video format in modern PDF readers. However, adding hyperlinks to externally hosted videos (like YouTube or Vimeo) is strongly recommended to ensure cross-platform compatibility and keep document file sizes small.
