that is my code to make the video for upload

   $video = $request->file('video');

    // Step 1: Upload the original video to Amazon S3
    $originalVideoPath = Storage::disk('s3')->putFile('videos', $video, 'public');

    // Step 2: Generate a URL for the uploaded video
    $originalVideoUrl = Storage::disk('s3')->url($originalVideoPath);

    // Step 3: Transcode the video with FFmpeg
    $ffmpeg = FFMpeg::fromDisk('s3');
    /* -fpsmax 60 -preset ultrafast -c:a aac -b:a 128k -ac 1 -pix_fmt yuv420p -movflags +faststart -t 59 -y */
    $format = (new \FFMpeg\Format\Video\X264())->setAdditionalParameters(['-pix_fmt', 'yuv420p']);
    $randomStr = substr(str_shuffle("0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"), 0, 10);

    $ffmpeg->open($originalVideoPath)
    ->export()
    /*  \ */

        ->addFilter(function (VideoFilters $filters) {
            $filters->custom('scale=iw*min(1280/iw\,720/ih):ih*min(1280/iw\,720/ih)')->resize(new Dimension(1024, 490), $mode = \FFMpeg\Filters\Video\ResizeFilter::RESIZEMODE_INSET, true)
            ->crop(new \FFMpeg\Coordinate\Point(0, 0), new \FFMpeg\Coordinate\Dimension(1024, 490));

        })

        ->addFilter(function (VideoFilters $filters) {
            $filters->custom('pad=1280:720:(1280-iw)/2:(720-ih)/2');

        })    
        ->addFilter('-fpsmax', '60', '-preset', 'ultrafast', '-c:a', 'aac', '-b:a', '128k', '-ac', '1', '-pix_fmt', 'yuv420p', '-movflags', '+faststart', '-t', '59', '-y')
        ->toDisk('s3')
        ->inFormat($format)
        ->save('transcoded/' . pathinfo($originalVideoPath, PATHINFO_FILENAME) . $randomStr . '.mp4');
    // Step 4: Generate the URL for the transcoded video
    $transcodedVideoPath = 'transcoded/' . pathinfo($originalVideoPath, PATHINFO_FILENAME) . $randomStr . '.mp4';
    // Make the transcoded video public
    Storage::disk('s3')->setVisibility($transcodedVideoPath, 'public');
    $transcodedVideoUrl = Storage::disk('s3')->url($transcodedVideoPath);
    return $transcodedVideoUrl;
