Streaming media on the Sync mobile apps

Sync Pro and Business customers can stream audio and video files via the Sync mobile apps. This makes it easy to view videos and listen to audio, without downloading first.

In this article:

How to stream an audio or video file

  1. Open the Sync mobile app.
  2. Browse to the audio or video file you’d like to play.
  3. Tap the file.
  4. The file will open in the built-in player, and stream, if the file type is supported.

Note: Streaming is only available on Pro Sync accounts. If you are on a free Sync Starter plan media will download first, before playing.

Supported file types


  • On iOS streaming is only supported over WiFi only (not Data).
  • MP4, MPG, MOV, AVI


  • On Android streaming is supported over WiFi and Data.
  • MP4, MPG, MOV
  • MP3, M4A, WAV, OGG

Note: Sync does not transcode or re-encode your videos. Videos play at maximum resolution and bitrate.

Troubleshooting streaming issues

Constant loading or spinning: The video bitrate may be too high to stream over the available bandwidth. The solution would be to re-encode your video at a lower bitrate.

No audio: The video may be using an unsupported audio type. The solution would be to re-encode your video using a supported audio type as per the list above.

High network utilization: High video bitrates (eg. 4K) may saturate your network. The solution would be to re-encode your video at a lower bitrate.

Blank or black player screen: The video type is not supported.
