How to Fix iPhone H.265 Videos Not Playing in Acrobat PDFs
Question details
Users are unable to play embedded iPhone 12 videos in distributed PDF files.

- Product
- Adobe Acrobat
- Device & OS
- iPhone 12
- Scenario
- Distributing a PDF document that contains embedded video content recorded on a modern iPhone.
- Observed behavior
- The video embeds successfully using Acrobat Rich Media tools, but fails to play when recipients open the PDF.
Ensure you have access to a video conversion tool and your original iPhone video file on your computer before editing the PDF.
Convert and Re-embed the Video in H.264 Format
Converting the H.265 iPhone video to a universally supported H.264 MP4 ensures recipients can play the media without missing codecs.
Modern iPhones record video in High Efficiency (HEVC/H.265) formats to save storage space. However, Adobe Acrobat and most standard PDF readers require H.264-encoded MP4 files for native media playback. Converting the file before embedding is the most reliable way to guarantee it works for all recipients.
Move the original video file from your iPhone to your PC or Mac.
Use a dedicated video conversion software or a trusted online converter to change the video from HEVC/H.265 to an MP4 file with H.264 video encoding and AAC audio.
Open your PDF document in Adobe Acrobat, navigate to the 'Tools' menu, select 'Rich Media', and delete the previously embedded video that isn't playing.
Click 'Add Video' on the Rich Media toolbar, browse for your newly converted H.264 MP4 file, and click on the page to place it.
Save the updated PDF file. Open the file in standard Adobe Reader to test the playback, ensuring recipients won't encounter codec errors.

Frequently Asked Questions
Why does Acrobat support MP4 files but not my iPhone video?
While your iPhone video may have an .mp4 or .mov file extension, the internal video data is likely encoded with H.265 (HEVC). Adobe Acrobat and standard PDF readers primarily support H.264 encoding for reliable playback.
How can I change my iPhone camera settings to record in compatible H.264?
Go to your iPhone Settings, scroll down to Camera, tap 'Formats', and select 'Most Compatible'. This forces the iPhone to record future videos in the widely supported H.264 format instead of High Efficiency (H.265).
Do recipients need special software to play H.264 videos inside a PDF?
No, standard H.264 MP4 files are natively supported by Adobe Reader and most modern PDF viewers, meaning your recipients won't need to install extra video players or missing codecs.
