You haven't mentioned that you have permanently deleted photos from a Mac or an iPhone, but both a Mac and an iPhone only keep the deleted items for 30 days. When time passes, you can no longer restore the deleted videos from the Recently Deleted folder or Mac Trash. If you have a backup, you can restore the deleted items from the backup. But if you have no backup, you can finally try using data recovery software to scan for the file traces. The data recovery software success rate depends on whether you have overwritten the deleted items and how much you have overwritten. The fewer the deleted files were overwritten with new data, the higher the data recovery success rate is.
