create thumbnails of images and videos uploaded to s3?

I need to create thumbnails of images and videos uploaded to s3. My current plan is to use sns to send a message and add to an SQS when media is uploaded. And then just pop off media from SQS and do the processing and upload to s3 from a node js app.

Is there a more elegant way to do this? I'd like to not use the bandwidth of downloading each image/video and then uploading 2 thumbnails each. Is there a more cloud friendly way to do this with aws?
