## **簡介**

透過將 PowerPoint 簡報轉換為影片，您將獲得

* **可及性提升**：相較於開啟簡報的應用程式，所有裝置（不論平台）皆預設配備影片播放器，使用者更容易開啟或播放影片。
* **更廣的觸及範圍**：透過影片，您可以觸及大量觀眾，並以資訊針對他們，這些資訊在簡報中可能顯得冗長。大多數調查與統計顯示，觀看與消費影片的人數超過其他形式的內容，且普遍較偏好此類內容。

## **Aspose.Slides 中的 PowerPoint 轉影片轉換**

Aspose.Slides 支援簡報轉影片的轉換。

* 使用 **Aspose.Slides** 產生一組畫格（來自簡報投影片），其對應特定的 FPS（每秒畫格數）
* 使用第三方工具，如 **ffmpeg**（[for java](https://github.com/bramp/ffmpeg-cli-wrapper)），根據畫格建立影片。

### **將 PowerPoint 轉換為影片**

1. 將以下內容加入您的 POM 檔案：
```xml
   <dependency>
     <groupId>net.bramp.ffmpeg</groupId>
     <artifactId>ffmpeg</artifactId>
     <version>0.7.0</version>
   </dependency>
```php

```

2. Download ffmpeg [here](https://ffmpeg.org/download.html).

4. Run the PowerPoint to video PHP code.

This PHP code shows you how to convert a presentation (containing a figure and two animation effects) to a video:

```php
  $presentation = new Presentation();
  try {
    # 新增笑臉形狀並對其進行動畫
    $smile = $presentation->getSlides()->get_Item(0)->getShapes()->addAutoShape(ShapeType::SmileyFace, 110, 20, 500, 500);
    $mainSequence = $presentation->getSlides()->get_Item(0)->getTimeline()->getMainSequence();
    $effectIn = $mainSequence->addEffect($smile, EffectType::Fly, EffectSubType::TopLeft, EffectTriggerType::AfterPrevious);
    $effectOut = $mainSequence->addEffect($smile, EffectType::Fly, EffectSubType::BottomRight, EffectTriggerType::AfterPrevious);
    $effectIn->getTiming()->setDuration(2.0);
    $effectOut->setPresetClassType(EffectPresetClassType::Exit);
    $fps = 33;

    class FrameTick {
      function invoke($sender, $arg) {
            try {
                $frame = sprintf("frame_%04d.png", $sender->getFrameIndex());
                $arguments->getFrame()->save($frame, ImageFormat::Png);
                $frames->add($frame);
                } catch (JavaException $e) {
                  }
             }
    }

    $frames = new Java("java.util.ArrayList");
    $animationsGenerator = new PresentationAnimationsGenerator($presentation);
    try {
      $player = new PresentationPlayer($animationsGenerator, $fps);
      try {
        $frameTick = java_closure(new FrameTick(), null, java("com.aspose.slides.PresentationPlayerFrameTick"));
        $player->setFrameTick($frameTick);
        $animationsGenerator->run($presentation->getSlides());
      } finally {
        if (!java_is_null($player)) {
          $player->dispose();
        }
      }
    } finally {
      if (!java_is_null($animationsGenerator)) {
        $animationsGenerator->dispose();
      }
    }
    # Configure ffmpeg binaries folder. See this page: https://github.com/rosenbjerg/FFMpegCore#installation
    $ffmpeg = new Java("net.bramp.ffmpeg.builder.FFmpeg", "path/to/ffmpeg");
    $ffprobe = new Java("net.bramp.ffmpeg.builder.FFprobe", "path/to/ffprobe");
    $builder = (new Java("net.bramp.ffmpeg.builder.FFmpegBuilder"))->addExtraArgs("-start_number", "1")->setInput("frame_%04d.png")->addOutput("output.avi")->setVideoFrameRate(FFmpeg->FPS_24)->setFormat("avi")->done();
    $executor = new Java("net.bramp.ffmpeg.builder.FFmpegExecutor", $ffmpeg, $ffprobe);
    $executor->createJob($builder)->run();
  } catch (JavaException $e) {
    $e->printStackTrace();
  }
```

## **Video Effects**

You can apply animations to objects on slides and use transitions between slides. 

{{% alert color="primary" %}} 

You may want to see these articles: [PowerPoint Animation](https://docs.aspose.com/slides/zh-hant/php-java/powerpoint-animation/), [Shape Animation](https://docs.aspose.com/slides/zh-hant/php-java/shape-animation/), and [Shape Effect](https://docs.aspose.com/slides/zh-hant/php-java/shape-effect/).

{{% /alert %}} 

Animations and transitions make slideshows more engaging and interesting—and they do the same thing for videos. Let's add another slide and transition to the code for the previous presentation:

```php
  # 新增笑臉形狀並對其進行動畫
  # ...
  # 新增投影片與動畫過場效果
  $newSlide = $presentation->getSlides()->addEmptySlide($presentation->getSlides()->get_Item(0)->getLayoutSlide());
  $newSlide->getBackground()->setType(BackgroundType::OwnBackground);
  $newSlide->getBackground()->getFillFormat()->setFillType(FillType::Solid);
  $newSlide->getBackground()->getFillFormat()->getSolidFillColor()->setColor(java("java.awt.Color")->MAGENTA);
  $newSlide->getSlideShowTransition()->setType(TransitionType::Push);

```

Aspose.Slides also supports animation for texts. So we animate paragraphs on objects, which will appear one after the other (with the delay set to a second):

```php
  $presentation = new Presentation();
  try {
    # 新增文字與動畫
    $autoShape = $presentation->getSlides()->get_Item(0)->getShapes()->addAutoShape(ShapeType::Rectangle, 210, 120, 300, 300);
    $para1 = new Paragraph();
    $para1->getPortions()->add(new Portion("Aspose Slides for Java"));
    $para2 = new Paragraph();
    $para2->getPortions()->add(new Portion("convert PowerPoint Presentation with text to video"));
    $para3 = new Paragraph();
    $para3->getPortions()->add(new Portion("paragraph by paragraph"));
    $paragraphCollection = $autoShape->getTextFrame()->getParagraphs();
    $paragraphCollection->add($para1);
    $paragraphCollection->add($para2);
    $paragraphCollection->add($para3);
    $paragraphCollection->add(new Paragraph());
    $mainSequence = $presentation->getSlides()->get_Item(0)->getTimeline()->getMainSequence();
    $effect1 = $mainSequence->addEffect($para1, EffectType::Appear, EffectSubType::None, EffectTriggerType::AfterPrevious);
    $effect2 = $mainSequence->addEffect($para2, EffectType::Appear, EffectSubType::None, EffectTriggerType::AfterPrevious);
    $effect3 = $mainSequence->addEffect($para3, EffectType::Appear, EffectSubType::None, EffectTriggerType::AfterPrevious);
    $effect4 = $mainSequence->addEffect($para3, EffectType::Appear, EffectSubType::None, EffectTriggerType::AfterPrevious);
    $effect1->getTiming()->setTriggerDelayTime(1.0);
    $effect2->getTiming()->setTriggerDelayTime(1.0);
    $effect3->getTiming()->setTriggerDelayTime(1.0);
    $effect4->getTiming()->setTriggerDelayTime(1.0);
    $fps = 33;

    class FrameTick {
      function invoke($sender, $arg) {
            try {
                $frame = sprintf("frame_%04d.png", $sender->getFrameIndex());
                $arguments->getFrame()->save($frame, ImageFormat::Png);
                $frames->add($frame);
                } catch (JavaException $e) {
                  }
             }
    }

    $frames = new Java("java.util.ArrayList");
    $animationsGenerator = new PresentationAnimationsGenerator($presentation);
    try {
      $player = new PresentationPlayer($animationsGenerator, $fps);
      try {
        $frameTick = java_closure(new FrameTick(), null, java("com.aspose.slides.PresentationPlayerFrameTick"));
        $player->setFrameTick($frameTick);
        $animationsGenerator->run($presentation->getSlides());
      } finally {
        if (!java_is_null($player)) {
          $player->dispose();
        }
      }
    } finally {
      if (!java_is_null($animationsGenerator)) {
        $animationsGenerator->dispose();
      }
    }
    # Configure ffmpeg binaries folder. See this page: https://github.com/rosenbjerg/FFMpegCore#installation
    $ffmpeg = new Java("net.bramp.ffmpeg.builder.FFmpeg", "path/to/ffmpeg");
    $ffprobe = new Java("net.bramp.ffmpeg.builder.FFprobe", "path/to/ffprobe");
    $builder = (new Java("net.bramp.ffmpeg.builder.FFmpegBuilder"))->addExtraArgs("-start_number", "1")->setInput("frame_%04d.png")->addOutput("output.avi")->setVideoFrameRate(FFmpeg->FPS_24)->setFormat("avi")->done();
    $executor = new Java("net.bramp.ffmpeg.builder.FFmpegExecutor", $ffmpeg, $ffprobe);
    $executor->createJob($builder)->run();
  } catch (JavaException $e) {
    $e->printStackTrace();
  }
```

## **Video Conversion Classes**

To allow you to perform PowerPoint to video conversion tasks, Aspose.Slides provides the [PresentationAnimationsGenerator](https://reference.aspose.com/slides/zh-hant/php-java/aspose.slides/presentationanimationsgenerator/) and [PresentationPlayer](https://reference.aspose.com/slides/zh-hant/php-java/aspose.slides/presentationplayer/) classes.

[PresentationAnimationsGenerator](https://reference.aspose.com/slides/zh-hant/php-java/aspose.slides/presentationanimationsgenerator/) allows you to set the frame size for the video (that will be created later) through its constructor. If you pass an instance of the presentation, `Presentation::getSlideSize` will be used and it generates animations that [PresentationPlayer](https://reference.aspose.com/slides/zh-hant/php-java/aspose.slides/presentationplayer/) uses.

When animations are generated, a `NewAnimation` event is generated for each subsequent animation, which has the presentation animation player parameter. The latter is a class that represents a player for a separate animation.

To work with the presentation animation player, the `getDuration` (the full duration of the animation) and   `setTimePosition` methods are used. Each animation position is set within the *0 to duration* range, and then the `getFrame` method will return a BufferedImage that corresponds to the animation state at that moment:

```php
use aspose\slides\Presentation;
use aspose\slides\PresentationPlayer;
use aspose\slides\PresentationAnimationsGenerator;
use aspose\slides\ImageFormat;
use aspose\slides\ShapeType;
use aspose\slides\EffectType;
use aspose\slides\EffectSubtype;
use aspose\slides\EffectTriggerType;
use aspose\slides\EffectPresetClassType;

class PresentationAnimationPlayer {
    function invoke($animationPlayer) {
        echo(sprintf("Animation total duration: %f", $animationPlayer->getDuration()));
        $animationPlayer->setTimePosition(0);// initial animation state
        try {
            # initial animation state bitmap
            $animationPlayer->getFrame()->save("firstFrame.png", ImageFormat::Png);
        } catch (JavaException $e) {
        }
        $animationPlayer->setTimePosition($animationPlayer->getDuration());// final state of the animation
        try {
            # last frame of the animation
            $animationPlayer->getFrame()->save("lastFrame.png", ImageFormat::Png);
        } catch (JavaException $e) {
        }
    }
}
$presentation = new Presentation();
try {
    # 新增笑臉形狀並對其進行動畫
    $smile = $presentation->getSlides()->get_Item(0)->getShapes()->addAutoShape(ShapeType::SmileyFace, 110, 20, 500, 500);
    $mainSequence = $presentation->getSlides()->get_Item(0)->getTimeline()->getMainSequence();
    $effectIn = $mainSequence->addEffect($smile, EffectType::Fly, EffectSubtype::TopLeft, EffectTriggerType::AfterPrevious);
    $effectOut = $mainSequence->addEffect($smile, EffectType::Fly, EffectSubtype::BottomRight, EffectTriggerType::AfterPrevious);
    $effectIn->getTiming()->setDuration(2.0);
    $effectOut->setPresetClassType(EffectPresetClassType::Exit);
    $animationsGenerator = new PresentationAnimationsGenerator($presentation);
    $presentationAnimation=java_closure(new PresentationAnimationPlayer(), null, java("com.aspose.slides.PresentationAnimationsGeneratorNewAnimation"));
    try {
        $animationsGenerator->setNewAnimation($presentationAnimation);
    } finally {
        if (!java_is_null($animationsGenerator)) {
            $animationsGenerator->dispose();
        }
    }
} finally {
    if (!java_is_null($presentation)) {
        $presentation->dispose();
    }
}
```

To make all animations in a presentation play at once, the [PresentationPlayer](https://reference.aspose.com/slides/zh-hant/php-java/aspose.slides/presentationplayer/) class is used. This class  takes a [PresentationAnimationsGenerator](https://reference.aspose.com/slides/zh-hant/php-java/aspose.slides/presentationanimationsgenerator/) instance and FPS for effects in its constructor and then calls the `FrameTick` event for all the animations to get them played:

```php

class FrameTick {
      function invoke($sender, $arg) {
            try {
                $arguments->getFrame()->save("frame_" . $sender->getFrameIndex() . ".png", ImageFormat::Png);
                } catch (JavaException $e) {
                  }
             }
    }

  $presentation = new Presentation("animated.pptx");
  try {
    $animationsGenerator = new PresentationAnimationsGenerator($presentation);
    try {
      $player = new PresentationPlayer($animationsGenerator, 33);
      try {
        $frameTick = java_closure(new FrameTick(), null, java("com.aspose.slides.PresentationPlayerFrameTick"));
        $player->setFrameTick($frameTick);
        $animationsGenerator->run($presentation->getSlides());
      } finally {
        if (!java_is_null($player)) {
          $player->dispose();
        }
      }
    } finally {
      if (!java_is_null($animationsGenerator)) {
        $animationsGenerator->dispose();
      }
    }
  } finally {
    if (!java_is_null($presentation)) {
      $presentation->dispose();
    }
  }

然後產生的畫格可編譯成影片。請參閱[將 PowerPoint 轉換為影片](https://docs.aspose.com/slides/zh-hant/php-java/convert-powerpoint-to-video/#convert-powerpoint-to-video) 章節。
