Ever wondered how to animate a static image? The moving picture capability of Video Editor Kit has the answer. It adds authentic facial expressions to an image of faces by leveraging the AI algorithms such as face detection, face key point detection, facial expression feature extraction, and facial expression animation.

Impressive stuff, right? Let's move on and see how this capability can be integrated.

## Integration Procedure​
### Preparations​
For details, please check the [official document](https://developer.huawei.com/consumer/en/doc/development/Media-Guides/config-agc-0000001101108580?ha_source=hms1).
### Configuring a Video Editing Project​
1.Set the app authentication information.
You can set the information through an API key or access token.
Use the [setAccessToken](https://developer.huawei.com/consumer/en/doc/development/Media-References/mediaapplication-0000001149508209#section92907346177?ha_source=hms1) method to set an access token during initialization when the app is started. The access token needs to be set only once.
```
MediaApplication.getInstance().setAccessToken("your access token");
```
2.Set a License ID.
This ID is used to manage your usage quotas, so ensure that the ID is unique
```
MediaApplication.getInstance().setLicenseId("License ID");
```
2.1 Initialize the running environment for **HuaweiVideoEditor**.
When creating a video editing project, first create a **HuaweiVideoEditor** object and initialize its running environment. When exiting a video editing project, release the **HuaweiVideoEditor** object.
- Create a **HuaweiVideoEditor** object
```
HuaweiVideoEditor editor = HuaweiVideoEditor.create(getApplicationContext());
```
- Specify the position for the preview area
This area renders video images, which is implemented by creating SurfaceView in the fundamental capability SDK. Ensure that the preview area position on your app is specified before creating this area.
```
<LinearLayout   
    android:id="@+id/video_content_layout"   
    android:layout_width="0dp"   
    android:layout_height="0dp"   
    android:background="@color/video_edit_main_bg_color"   
    android:gravity="center"   
    android:orientation="vertical" />
// Specify the preview area position.
LinearLayout mSdkPreviewContainer = view.findViewById(R.id.video_content_layout);

// Set the layout of the preview area.
editor.setDisplay(mSdkPreviewContainer);
```
- Initialize the running environment. If the license verification fails, [LicenseException](https://developer.huawei.com/consumer/en/doc/development/Media-References/sdk-licenseexception-0000001164593066?ha_source=hms1) is thrown.
After the **HuaweiVideoEditor** object is created, it has not occupied any system resource. You need to manually set the time for initializing the running environment of the object. Then, necessary threads and timers will be created in the fundamental capability SDK.
```
try {
        editor.initEnvironment();
   } catch (LicenseException error) {
        SmartLog.e(TAG, "initEnvironment failed: " + error.getErrorMsg());   
        finish();
        return;
   }
```
2.2 Add a video or image.
Create a video lane and add a video or image to the lane using the file path.
```
// Obtain the HVETimeLine object.
HVETimeLine timeline = editor.getTimeLine();

// Create a video lane.
HVEVideoLane videoLane = timeline.appendVideoLane();

// Add a video to the end of the video lane.
HVEVideoAsset videoAsset = vidoeLane.appendVideoAsset("test.mp4");

// Add an image to the end of the video lane.
HVEImageAsset imageAsset = vidoeLane.appendImageAsset("test.jpg");
```
### Integrating the Moving Picture Capability​
```
// Add the moving picture effect.
videoAsset.addFaceReenactAIEffect(new HVEAIProcessCallback() {
        @Override
        public void onProgress(int progress) {
        // Handling progress.
        }

        @Override
        public void onSuccess() {
        // Handling success.
        }

        @Override
        public void onError(int errorCode, String errorMessage) {
        // Handling failure.
        }
    });

// Remove the moving picture effect.
videoAsset.removeFaceReenactAIEffect();
```
