PHP SDK for the ShotstackPHP video editor and cloud video editing API.
Shotstack is a cloud based video editing platform that enables the editing of videos using code.
The platform uses an API and a JSON format for specifying how videos should be edited and what assets and titles should be used.
A server based render farm takes care of rendering the videos allowing multiple videos to be created simultaneously.
For examples of how to use the SDK to create videos using code checkout the PHP demo repo:https://github.com/shotstack/php-demos
- Using the PHP SDK
- API Documentation and Guides
Requires PHP7.4+ and uses Guzzle7.3+.
The recommended way to use the SDK is as a composer package. Install using the command:
composer require shotstack/shotstack-sdk-php
The Shotstack SDK enables programmatic video editing via the Edit APIrender endpoint. Prepare JSON edits using theprovided schema classes andPOST to the API for rendering.
The example below trims the start of a video clip and plays it for 8 seconds. The edit is prepared using the SDK modelsand then sent to the API for rendering.
<?phprequire'vendor/autoload.php';useShotstack\Client\Api\EditApi;useShotstack\Client\Configuration;useShotstack\Client\Model\Edit;useShotstack\Client\Model\Output;useShotstack\Client\Model\Timeline;useShotstack\Client\Model\Track;useShotstack\Client\Model\Clip;useShotstack\Client\Model\VideoAsset;$config = Configuration::getDefaultConfiguration() ->setHost('https://api.shotstack.io/stage') ->setApiKey('x-api-key','H7jKyj90kd09lbLOF7J900jNbSWS67X87xs9j0cD');// use the correct API key$client =newEditApi(null,$config);$videoAsset =newVideoAsset();$videoAsset ->setSrc('https://s3-ap-southeast-2.amazonaws.com/shotstack-assets/footage/skater.hd.mp4') ->setTrim(3);$videoClip =newClip();$videoClip ->setAsset($videoAsset) ->setLength(8) ->setStart(0);$track =newTrack();$track->setClips([$videoClip]);$timeline =newTimeline();$timeline->setTracks([$track]);$output =newOutput();$output ->setFormat('mp4') ->setResolution('sd');$edit =newEdit();$edit ->setTimeline($timeline) ->setOutput($output);$render =$client->postRender($edit)->getResponse();
The example request below can be called a few seconds after the render above is posted. It will return the status ofthe render, which can take several seconds to process. It uses therender->getId() method returned by thepostRenderrequest.
useShotstack\Client\Api\EditApi;useShotstack\Client\Configuration;$config = Configuration::getDefaultConfiguration() ->setHost('https://api.shotstack.io/stage') ->setApiKey('x-api-key','H7jKyj90kd09lbLOF7J900jNbSWS67X87xs9j0cD');// use the correct API key$client =newEditApi(null,$config);$video =$client->getRender($render->getId())->getResponse();if ($video->getStatus() ==='done') {echo$video->getUrl();}
The example below uses the Edit we create in theVideo Editing Example and saves it as atemplate. The template can be rendered at a later date and can include placeholders. Placeholders can be replacedwhen rendered usingmerge fields.
This example uses a placeholder for the video src (URL), trim (TRIM), and length (LENGTH) to allow you to trim any videousing a template.
<?phprequire'vendor/autoload.php';useShotstack\Client\Api\EditApi;useShotstack\Client\ApiException;useShotstack\Client\Configuration;useShotstack\Client\Model\Edit;useShotstack\Client\Model\Output;useShotstack\Client\Model\Timeline;useShotstack\Client\Model\Track;useShotstack\Client\Model\Clip;useShotstack\Client\Model\VideoAsset;useShotstack\Client\Model\Template;$config = Configuration::getDefaultConfiguration() ->setHost('https://api.shotstack.io/stage') ->setApiKey('x-api-key','H7jKyj90kd09lbLOF7J900jNbSWS67X87xs9j0cD');// use the correct API key$client =newEditApi(null,$config);$videoAsset =newvideoAsset();$videoAsset ->setSrc('{{ URL }}') ->setTrim('{{ TRIM }}');$videoClip =newClip();$videoClip ->setAsset($videoAsset) ->setStart(0) ->setLength('{{ LENGTH }}');$track =newTrack();$track ->setClips([$videoClip]);$timeline =newTimeline();$timeline ->setTracks([$track]);$output =newOutput();$output ->setFormat('mp4') ->setResolution('sd');$edit =newEdit();$edit ->setTimeline($timeline) ->setOutput($output);$template =newTemplate();$template ->setName('Trim Template') ->setTemplate($edit);$response =$client->postTemplate($template)->getResponse();
The example below renders the template we created in the previous example and includes merge fields that will replacethe placeholders. Once submitted use the returned render ID and call theStatus Check Exampleto get the render progress. It uses theresponse->getId() method returned by thepostTemplate request.
useShotstack\Client\Api\EditApi;useShotstack\Client\Configuration;$config = Configuration::getDefaultConfiguration() ->setHost('https://api.shotstack.io/stage') ->setApiKey('x-api-key','H7jKyj90kd09lbLOF7J900jNbSWS67X87xs9j0cD');// use the correct API key$client =newEditApi(null,$config);$mergeFieldUrl =newMergeField();$mergeFieldUrl ->setFind('URL') ->setReplace('https://s3-ap-southeast-2.amazonaws.com/shotstack-assets/footage/skater.hd.mp4');$mergeFieldTrim =newMergeField();$mergeFieldTrim ->setFind('TRIM') ->setReplace(3);$mergeFieldLength =newMergeField();$mergeFieldLength ->setFind('LENGTH') ->setReplace(6);$template =newTemplateRender();$template ->setId($response->id) ->setMerge([$mergeFieldUrl,$mergeFieldTrim,$mergeFieldLength, ]);$video =$client->postTemplateRender($template)->getResponse();if ($video->getStatus() ==='done') {echo$video->getUrl();}

By default, all assets generated by the editing API are hosted by Shotstack and served via our CDN. The SDK providesaccess to the Serve API to retrieve information about hosted files. Files can also be deleted.
The example below uses a render ID to look up hosted assets associated with the render. Note that multiple assets can becreated for a render, i.e. video, thumb and poster. Each asset has a unique asset ID different to the render ID.
useShotstack\Client\Api\ServeApi;useShotstack\Client\Configuration;$config = Configuration::getDefaultConfiguration() ->setHost('https://api.shotstack.io/stage') ->setApiKey('x-api-key','H7jKyj90kd09lbLOF7J900jNbSWS67X87xs9j0cD');// use the correct API key$client =newServeApi(null,$config);$renderId ='140924c6-077d-4334-a89f-94befcfc0155';// Use a valid render ID$response =$client->getAssetByRenderId($renderId)->getData();foreach ($responseas$asset) {if ($asset->getAttributes()->getStatus() ==='ready') {echo"Status:" .strtoupper($asset->getAttributes()->getStatus()),PHP_EOL,PHP_EOL;echo">> Asset CDN URL:" .$asset->getAttributes()->getUrl(),PHP_EOL,PHP_EOL;echo">> Asset ID:" .$asset->getAttributes()->getId(),PHP_EOL,PHP_EOL;echo">> Render ID:" .$asset->getAttributes()->getRenderId(),PHP_EOL,PHP_EOL; }}
Every asset has a unique asset ID, the example below looks up an asset by its asset ID.
