TYPO3 filereference adding two files - typo3

Question

I have TYPO3 7.6.18
this is my code:
$newVideo = new \Istar\Fefiles\Domain\Model\Video();
$videoName = $video['name'];
$videoTmpName = $video['tmp_name'];
$resourceFactory = \TYPO3\CMS\Core\Resource\ResourceFactory::getInstance();
$storage = $resourceFactory->getDefaultStorage();
$folder = $storage->getFolder("user_upload/");
$movedFile = $storage->addFile($videoTmpName, $folder, $videoName);
$newFileReference = $this->objectManager$this->objectManager->get('TYPO3\\CMS\\Extbase\\Domain\\Model\\FileReference');
$newFileReference->setFile($movedFile);
$newVideo->setVideo($newFileReference);
$this->videoRepository->add($newVideo);
$persistenceManager = $this->objectManager->get("TYPO3\\CMS\\Extbase\\Persistence\\Generic\\PersistenceManager");
$persistenceManager->persistAll();
The problem is it added two files to field video file reference. It's very sudenly! And second file is't the same, it's diferent files. I sure, I send one file. Where may be the problem ?
I have model photo, and there is field image
'image' => [
'exclude' => 0,
'label' => 'LLL:EXT:fefiles/Resources/Private/Language/locallang_db.xlf:image',
'config' => \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::getFileFieldTCAConfig('image', [
'appearance' => [
'createNewRelationLinkTitle' => 'LLL:EXT:cms/locallang_ttc.xlf:images.addFileReference'
],
'maxitems' => 1,
], $GLOBALS['TYPO3_CONF_VARS']['GFX']['imagefile_ext'])
],
Anf I see that when I create photo from BE, and upload image - this add second image, which was uploaded on site early. This is very strange! What happens ?

Answer 1

Have a look at the sys_file_reference table before and after you create a new record in the backend. Is there a new record added? And after saving an existing record you don't get the random image/video added?

Answer 2

Solution:
'foreign_match_fields' => array(
'fieldname' => 'image',
'tablenames' => 'tx_fefiles_domain_model_photo',
'table_local' => 'sys_file_reference',
),
