That is not a shortcode, I know it looks like one but it's really not. You can use this instead:

<?php apply_filters( 'the_content', '[smooth=id:1; width:650; height:400; timed:true; arrows:false; carousel:false; links:false; info:true; frames:false; delay:8000; transition:fade;]'); ?>

What's inside the function all is returned by do_shortcode function if there are no shortcodes defined in WordPress. Adn this can happen if you are making a call before the plugins executed their actions (usually before init()), or plugin didn't registered shortcode in the first place. Without debugging I can't tell you exactly what is the cause.

your problem is not so clear to me but i can give you some example of using do_shortcode here is some code- its a sample use of shortcode

<?php
$product_id = get_post_meta($post->ID, 'product_id, true); 
echo do_shortcode("[product id='$product_id']");
?>

id: The id you were already using on [ gallery=id ] width: Width of your image container height: Height of your image container timed: true/false to slideshow your images delay: Time in miliseconds before moving to the next image transition: Animation when moving to the next image: fade, fadeslideleft, continuoushorizontal, continuousvertical, crossfade, fadebg arrows: true/false to see the arrows for next/previous images info: true/false to show the image description carousel: true/false to see all thumbnails text: Text relative to the Carousel open: true/false to show the carousel opened/closed links: true/false to click on the image and open the original image alone margin: Distance from the gallery border to the text align: Gallery alignment: left, right, center, float_left, float_right

[smooth=id:xx; arrows:true; carousel:true; links:true; width:500; height:300;]

[smooth=galleryId, width, height, timed, arrows, carousel, links]

[smooth=12345, 400, 400, false, true, true, true]
