How Acrobat Handles Interactive PDF Rich Media After Flash Player End of Support
Question details
The user wants to know how to play or view interactive PDFs containing rich media (video and audio) now that Adobe Flash Player is discontinued, and whether older annotations remain playable.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Viewing or creating interactive PDFs with embedded video and audio annotations after the Flash Player end-of-life.
- Observed behavior
- Interactive PDFs created with older versions of InDesign that depend strictly on Flash Player can no longer play multimedia content in modern or older PDF readers.
Ensure your computer's operating system has standard native H.264 media codecs installed, as modern PDF readers rely on system codecs rather than third-party plugins like Flash.
Embed and Play Supported Modern Media Formats
Use modern, standard multimedia formats that do not rely on Flash Player to ensure seamless playback in Acrobat and other PDF readers.
With the discontinuation of Adobe Flash Player, PDF software now utilizes native system codecs to play embedded rich media. Legacy Flash-based media (like SWF or FLV) will no longer function natively in any recent PDF application.
Ensure your video and audio files are in modern formats. Supported types include MP3 audio and H.264-compressed MP4, MOV, M4V, 3GP, and 3G2 video files.
Verify that your computer has H.264 codecs installed. Most modern operating systems include these by default, but they are strictly required for playing compressed video in PDFs.
Use a recent version of Acrobat Pro DC or Adobe InDesign (version 2021 or newer) to insert the modern media files into your PDF document.
Open the newly exported interactive PDF in Acrobat or Adobe Reader and click on the media annotation to verify that it plays smoothly without Flash prompts.
Open Media via External Applications
If you have media files in other unsupported formats, you can configure your PDF reader to launch an external media player.

Frequently Asked Questions
Can I still play interactive PDFs created with InDesign CS5?
No. PDFs created with older software like InDesign CS5 rely entirely on Adobe Flash Player for rich media playback. Since Flash has reached its end of support, these files can no longer be played in modern or older PDF readers.
What multimedia formats are officially supported in modern PDFs?
Modern PDF readers natively support MP3 files for audio. For video, they support MP4, MOV, M4V, 3GP, and 3G2 formats, provided that the video uses H.264 compression.
Do I need to download extra software to play MP4 videos in a PDF?
No extra plugins like Flash are needed, but your computer's operating system must have standard H.264 codecs installed. Most modern OS versions (like Windows 10/11 and macOS) include these natively.
How do I create a new interactive PDF that doesn't need Flash?
You need to use updated creation software such as Acrobat Pro DC or Adobe InDesign 2021 (or newer). When inserting media, choose standard MP4 or MP3 files rather than legacy SWF or FLV files.
