| FaceDetectionandTracking ( this operations, string subscriptionKey = default(string), string ocpApimSubscriptionKey = default(string) ) : void |
<p>Detects and tracks human faces in a video and returns face locations. <br/>• The supported input video formats include MP4, MOV, and WMV. Video file size should be no larger than 100MB. <br/>• The detectable face size range is 24x24 to 2048x2048 pixels. The faces out of this range will not be detected. <br/>• For each video, the maximum number of faces returned is 64. <br/>• Some faces may not be detected due to technical challenges; e.g. very large face angles (head-pose), and large occlusion. Frontal and near-frontal faces have the best results. <br/>• Output files are deleted after 24 hours. </p>

<p>Detects motion in a video, and returns the frame and duration of the motion that was captured. <br/>• The supported input video formats include MP4, MOV, and WMV. Video file size should be no larger than 100MB. <br/>• User can input detection zones to set up as areas to detect motion. <br/>• User can specify motion sensitivity: high, medium, and low. Higher sensitivity means more motions will be detected at a cost that more false alarms will be reported.<br/>• Motion Detection is optimized for stationary background videos. <br/>• User can specify whether light change events should be detected. A light change refers to a change in the frame that was caused by a light turning off and on. Some developers do not want to detect this, as they consider it a false alarm. Other developers want to make sure they capture any change, light changes included.<br/>• User can specify whether successive motions should be merged together by passing in a parameter (mergeTimeThreshold) For example, if a motion happens from 1 to 4 seconds and the next motion happens from 5 to 10 seconds, some developers will want to count that as one instance of motion.<br/>• User can specify which frames to be detected by passing in a parameter (frameSamplingValue).<br/>• Some motion may not be detected due to technical challenges; e.g. semi-transparent objects, and some small objects. <br/>• Output files are deleted after 24 hours. </p>

| Thumbnail ( this operations, double maxMotionThumbnailDurationInSecs = default(double?), bool outputAudio = default(bool?), bool fadeInFadeOut = default(bool?), string subscriptionKey = default(string), string ocpApimSubscriptionKey = default(string) ) : void |
Generates a motion thumbnail from a video. The Video Thumbnail API provides an automatic summary for videos to let people see a preview or snapshot quickly. Selection of scenes from a video create a preview in form of a short video. <br/> • The supported input video formats include MP4, MOV, and WMV. Video file size should be no larger than 100MB. <br/> • The number of scenes displayed in the thumbnail is either chosen by the user or defaults to the optimal duration supported by the Video API’s algorithm.<br/> • A scene is a collection of indexed frames. Scenes are mapped according to sequence in video. <br/> • Fade in/fade out effects are included in the thumbnail by default, but can be turned off by the user. <br/> • Audio is included by default, but can be turned off by the user. Pauses in audio are detected to divide video into coherent scenes and avoid breaking sentences of speech.<br/> • Output files are deleted after 24 hours.<br/> <br/> * Optimal Duration of Video Thumbnail Supported by Video API shown in table below. <table class="element table"> <thead> </thead> <tbody> <tr> <td>Motion Thumbnail</td> </tr> <tr> <td>Video duration (d)</td> <td>d < 3min</td> <td>3min < d < 15min</td> <td>15min < d < 30min</td> <td>30min < d</td> </tr> <tr> <td>Thumbnail duration</td> <td>15sec (2-3 scenes)</td> <td>30sec (3-5 scenes)</td> <td>60sec (5-10 scenes)</td> <td>90sec (10-15 scenes)</td> </tr> <tbody> </table>
