- Product
- PDF Reader / Editor
- Device & OS
- not provided
- Scenario
- Attempting to play embedded video media within a PDF document.
- Observed behavior
- Video playback controls are completely missing and do not appear, even when the option to show all controls has been explicitly enabled.
Verify that your PDF viewing application is fully updated, and check if the document contains an outdated Adobe Flash video format, which is no longer supported by modern software.
Re-embed the Video Using a Supported Format
Because Adobe Flash Player has reached end-of-life, older Flash-based videos will no longer render playback controls. Converting and re-embedding the video in a modern format like MP4 resolves the issue.
Compatibility heavily depends on the application and version used to create the document. If an older tool was used to embed a Flash video (.flv or .swf), current PDF readers will fail to load the interactive controls.
Check the original source file of the video to see if it is in an outdated format such as FLV, SWF, or an older QuickTime codec.
Use a video conversion tool to convert your original video file into standard MP4 (H.264) format, which is universally supported by modern PDF editors.
Open your PDF editing software, delete the non-working video box, and use the 'Add Media' or 'Insert Video' tool to embed the newly converted MP4 file.
During the insertion process, ensure that the 'Show Player Controls' or 'Play on Click' properties are checked before saving the document.
Update or Change Your PDF Reader Application
Sometimes the PDF reader being used lacks native multimedia support or requires an update to process the rich media content correctly.
Easily Embed and Play Media with WPS Office

- 1. Download and install WPS Office: Get WPS Office from the official website and open the application on your device.
- 2. Open your PDF document: Launch the WPS PDF tool and open the document containing your rich media.
- 3. Insert or manage video: Navigate to the Insert tab, select Video, and choose your MP4 file to embed it seamlessly with working controls.
Frequently Asked Questions
Why did my PDF video stop working after a recent update?
If your video was encoded using Adobe Flash, it will no longer work because Flash Player has reached its end of life and is permanently disabled in all modern software updates.
What is the best video format to use in a PDF document?
MP4 (encoded with H.264 video and AAC audio) is widely considered the most reliable and universally supported format for embedding rich media into PDF files.
Can I force the video playback controls to appear?
No. If the video format is unsupported or improperly encoded by the original creator, the interactive playback controls simply will not render, even if the 'show controls' setting is enabled.
Do I need special plugins to view videos in PDFs?
Most modern PDF editors, including WPS Office, have built-in support for standard video formats like MP4. You typically do not need extra plugins unless the media relies on deprecated formats.
