Pengantar
Dengan mengonversi presentasi PowerPoint Anda menjadi video, Anda mendapatkan
- Peningkatan aksesibilitas: Semua perangkat (terlepas dari platform) dilengkapi dengan pemutar video secara default dibandingkan dengan aplikasi pembuka presentasi, sehingga pengguna lebih mudah membuka atau memutar video.
- Jangkauan lebih luas: Dengan video, Anda dapat menjangkau audiens yang besar dan menargetkan mereka dengan informasi yang mungkin terasa membosankan dalam presentasi. Sebagian besar survei dan statistik menunjukkan bahwa orang menonton dan mengonsumsi video lebih banyak daripada bentuk konten lainnya, dan mereka umumnya lebih menyukai konten tersebut.
Anda mungkin ingin memeriksa PowerPoint to Video Online Converter kami karena ini merupakan implementasi langsung dan efektif dari proses yang dijelaskan di sini.
Konversi PowerPoint ke Video di Aspose.Slides
Aspose.Slides mendukung konversi presentasi ke video.
- Gunakan Aspose.Slides untuk menghasilkan sekumpulan frame (dari slide presentasi) yang sesuai dengan FPS tertentu (frame per detik)
- Gunakan utilitas pihak ketiga seperti ffmpeg (untuk java) untuk membuat video berdasarkan frame-frame tersebut.

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:
$presentation = new Presentation();
try {
# Adds a smile shape and then animates it
$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();
}
}

$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();

$executor->createJob($builder)->run();
} catch (JavaException $e) {
$e->printStackTrace();
}
Video Effects
You can apply animations to objects on slides and use transitions between slides.
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:
# Adds a smile shape and animates it
# ...
# Adds a new slide and animated transition
$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):
$presentation = new Presentation();
try {
# Adds text and animations
$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();

Video Conversion Classes
To allow you to perform PowerPoint to video conversion tasks, Aspose.Slides provides the PresentationAnimationsGenerator and PresentationPlayer classes.
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 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:
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 {
# Adds a smile shape and animates it
$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)) {
$presentation->dispose();
}
}
To make all animations in a presentation play at once, the PresentationPlayer class is used. This class takes a PresentationAnimationsGenerator instance and FPS for effects in its constructor and then calls the FrameTick event for all the animations to get them played:
class FrameTick {
function invoke($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();
}
}
Kemudian frame yang dihasilkan dapat dikompilasi untuk menghasilkan video. Lihat bagian [Convert PowerPoint to Video](https://docs.aspose.com/slides/id/php-java/convert-powerpoint-to-video/#convert-powerpoint-to-video).
