**Description**  
I noticed that when I try to pin videos using PinUserVideoToFirstView(userID) function I always get black screen between videos. Is there a way to get rid of this black screen ?

**Which Desktop Meeting SDK version?**  
DeskTop Windows SDK v5.7.1.644

**To Reproduce(If applicable)**  
Steps to reproduce the behavior:  
if (count\_participants \> 3)  
{  
for (int i = m\_currentPinUserId; i \< count\_participants; i++)  
{  
unsigned int user\_id = participants-\>GetItem(i);  
ZOOM\_SDK\_NAMESPACE::IUserInfo\* user\_info = participantsCtlr-\>GetUserByUserID(user\_id);

```
		if (this->CanSpotlightOrPin(user_id))
		{

```

// videoCtrl-\>UnPinAllVideosFromFirstView();

```
			videoCtrl->UnPinVideoFromFirstView(last_user_id);

			if (videoCtrl->PinVideoToFirstView(user_id) == ZOOM_SDK_NAMESPACE::SDKERR_SUCCESS)
				{
					m_currentPinUserId = i;
					last_user_id = user_id;
					// done
					status = true;
					break;
				}
		}
	}
}

```
