How to Fix “Unsupported Video Format” Issue in iPhone?

iPhone users may encounter an issue preventing them from opening certain files on their mobiles, with errors stating “Format Not Supported” or “Source Unavailable”. This can lead to the loss of important photos or videos.

This problem typically arises when the iPhone doesn’t support the video or image format, or the files are damaged. Although there are no temporary fixes, We’ve tested several methods that should certainly resolve your issue.

How to Fix Unsupported Video Format?

  • Convert Files to a Supported Format: The iPhone only supports specific image, video, and audio formats. Video formats include .mp4, .mov, .3gp, and .m4v, while image formats consist of JPEG, PNG, GIF, RAW, HEIF, HEVC, and TIFF. Converting files to these supported formats will address issues related to unsupported formats.
  • Download Video via URL: If an ‘Unsupported format or source isn’t available’ error appears while viewing an online video, download it for offline viewing using a video downloader.
  • Re-download the Video: If your internet connection disrupted or your device shut down during the download, the video might not have downloaded correctly. Try redownloading it.
  • Download a Format-Supporting Application: If your iPhone can’t support a video file, install a format-supporting app to play the video.
  • Update your iPhone: An outdated iPhone software version might make video or image formats unsupported or report the source as unavailable.
