How can we help?

Open iPhone Settings, find Eigenvideo, and review its Photos access. With Limited Access, Eigenvideo can show only the videos you allowed. Adjust the selection or grant Full Access, then return to Eigenvideo and refresh.

Keep Eigenvideo open with a reliable internet connection while Photos downloads the original. If preparation stops, restore the connection and try again. Your original remains in Photos.

Reopen Eigenvideo. If compression was interrupted, choose Resume Compression, Delete Compressed Copies, or Keep Current Versions. If the compressed copies are already safely in Photos, choose Replace Originals, Delete Compressed Copies, or Keep Both. Avoid manually deleting either copy in Photos until the recovery is resolved.

Check that the selected videos are still available in Photos and that Eigenvideo has access to them. If a video is stored in iCloud, keep the app open on a reliable connection while Photos prepares it, then try again.

Open Apple Photos and check Recently Deleted. If iCloud Photos is enabled, deletions can affect other devices signed into the same library. Recovery availability is controlled by Photos.

Keep both devices nearby and awake, confirm AirDrop is available, then try again. Cancelling preparation or dismissing the share sheet does not change the original video.

When you use Compress Replace on a video in your iCloud Shared Photo Library, the compressed replacement is saved to your Personal Library. Apple does not provide a way for Eigenvideo to put the replacement back into the Shared Library automatically.

After replacement finishes, open the compressed video in Apple Photos, tap the More (…) button, and choose Move to Shared Library. Repeat for each replacement you want to share again. You can also select multiple replacements in Photos and move them together.

Read Apple’s guide to adding content to the Shared Library.

If you see “Nothing Was Replaced” with “Video export failed: Disk Full,” your iPhone does not have enough free space to create the compressed copy. Compress Replace needs temporary space for the new video before the original can be removed. The failed export does not replace the original.

Delete a few videos you no longer need to free space, then try Compress Replace again. Videos in Photos’ Recently Deleted can continue to take up space. If you need to empty them there, first make sure you no longer need them: permanently deleted videos cannot be recovered, and deletion with iCloud Photos can affect your other devices.

Eigenvideo currently compresses videos above 1080p when it expects meaningful storage savings. Videos already at 1080p (Full HD) or below are skipped, even if they have a high bitrate and take up a lot of space.

If you see “Already Optimized,” your selection contains no videos eligible for the current compression mode. This does not necessarily mean those videos could not be made smaller: bitrate—the amount of data used per second—also affects file size.

Planned for a future update: recompressing HD videos at a lower bitrate and an option to reduce 1080p videos to 720p. These options are not available in the current release. We plan to test them on varied real videos to balance storage savings and visible quality before choosing the settings. No release date is set.
