Generated animated GIF thumbnails from videos uploaded to an S3 bucket

Our project accepts video files uploaded to an AWS S3 bucket. When the file is uploaded I need to generate an animated thumbnail file. Here is the preferred workflow: 1) Customer uploads a video (MOV or MP4) 2) Bucket sends a notification through SNS 3) Your Lambda function is subscribed to this notification and is invoked 4) Your Lambda function generates the thumbnail file 5) Your Lambda function uploads the thumbnail file to another S3 bucket I have steps 1-3 completed. This project is for steps 4 and 5. The Lambda function should be expose the following configuration option as an environment variable: thumbnailLength: Duration in milliseconds of the generated thumbnail (default 2000) The thumbnail file that your Lambda function creates needs to be an animated GIF and capture {thumbnailLength} milliseconds from the middle of the uploaded video. The thumbnail GIF should "bounce". For example if there are 10 frames, the GIF will play frames 1-10 and then in reverse 10-1 to produce a bouncing effect. I have attached an example of a bouncing GIF. Uploaded videos will be up to 30 seconds in length. If the video is less than {thumbnailLength} milliseconds the thumbnail should be a still image of a single frame from the middle of that video. I prefer this be built in Node 10.x but would also accept Python. Extra consideration will be given if you can provide a CloudFormation template to deploy it. Build it in your own AWS account and give me access to a working version for review. Please only respond if you have read these requirements and are capable of completing the project. I am happy to answer any questions. Thanks!
