I want to be able to upload a 1000 x 1000px image as a featured image on a post but then be able to crop it to the required featured image size. Any way to enable this?

WordPress automatically creates all the images sizes when uploading your image that you have registered in your code/theme. You would need to change the size you require for your featured image so when you upload and set featured image its the correct size or create a new image size and update your template files to call this new featured image.

This can be achieved by either creating an image size using <?php add_image_size( 'my-image-size', 1000, 400, true ); ?> or you can implement the Aqua Resizer to your theme/plugin. Aqua Resizer works almost in the same fashion as the good old TimThumb, but instead saves the image as a correct image size in WordPress using WordPress' intermediate sizes methods.
This is called Post Thumbnails. It was set by your theme.
You can open file functions.php and search for set_post_thumbnail_size. If found, change it :
set_post_thumbnail_size(9999999,999999)
If not found, just insert new line.

1Please don't rollback my changes. It is a legit edit. All code needs to be in back ticks or code block. Thank you Commented Dec 8, 2014 at 12:46
