Video File Support

Codecs & Containers

For maximum browser compatibility, PhotoPrism can transcode video codecs and containers supported by FFmpeg to MPEG-4 AVC.

Running the following command in a terminal displays a list of supported codecs:

ffmpeg -decoders

See our advanced setup guide to learn how to configure hardware video transcoding.

Please Note:

1. Not all video and audio formats can be played with every browser. For example, AAC - the default audio codec for MPEG-4 AVC / H.264 - is supported natively in Chrome, Safari, and Edge, while it is only optionally supported by the OS in Firefox and Opera.
2. HEVC/H.265 video files can have a .mp4 file extension too, which is often associated with AVC only. This is because MP4 is a container format, meaning that the actual video content may be compressed with H.264, H.265, or something else. The file extension doesn't really tell you anything other than that it's probably a video file.
3. In case FFmpeg is disabled or not installed, videos cannot be indexed because still images cannot be created. You should also have Exiftool enabled to extract metadata such as duration, resolution, and codec.

Hybrid Photo/Video Formats

For more information on hybrid photo/video file formats, e.g. Apple Live Photos and Samsung/Google Motion Photos, see github.com/photoprism/photoprism/tree/develop/pkg/media and docs.photoprism.app/developer-guide/media/live.

Standard Resolutions

The PHOTOPRISM_FFMPEG_SIZE config option allows to limit the resolution of transcoded videos. It accepts the following standard sizes, while other values are automatically adjusted to the next supported size:
