A scalable solution for colorizing black and white videos using DeOldify and AWS is introduced in the following text. The solution utilizes AWS services to create an efficient workflow capable of handling multiple videos at once and producing impressive colorization results.

A Scalable Video Colorization Solution

TrackIt has developed a workflow centered around DeOldify, a powerful Open Source deep learning model for colorizing black and white images and videos. The solution also leverages AWS services such as Amazon S3, AWS Lambda, Amazon Elastic Transcoder, Amazon SQS, and Amazon EC2 Spot Instances. The workflow provides the following benefits:

  1. Process multiple videos simultaneously: Video segmentation is used to handle multiple video clips at one time. The parallel processing significantly reduces the time required to colorize large batches of videos.
  1. Optimize costs and performance: Amazon EC2 Spot Instances and Auto Scaling Groups are utilized to cut costs while ensuring optimal performance for video colorization.
  1. Benefit from a fully managed and integrated solution: AWS services are fully integrated and a seamless and efficient colorization process is enabled without manually managing resources.

Workflow Overview

  1. A black and white video is uploaded to an Amazon S3 input bucket
  2. An AWS Lambda function is triggered which segments the video using Amazon Elastic Transcoder
  3. The video segments are stored in another S3 bucket and a message is sent to an Amazon SQS queue
  4. Amazon EC2 Spot Instances managed by an Auto Scaling Group are launched to process the video segments
  5. The colorized video segments are stored in an output S3 bucket
  6. Another Lambda function is triggered to merge the colorized segments back into a single video file

Cost Breakdown

Below are the estimated workflow costs for a 1-hour video with both On-Demand and Spot instances using g4dn.xlarge instances in the Oregon region:

Total cost of the workflow for a 1-hour video:

  • Amazon S3 storage:
    • Input bucket: $0.023 (assuming 10GB storage)
    • Output bucket: $0.023 (assuming 10GB storage)
    • Total: $0.046
  • Amazon S3 data transfer: $0.18 (assuming 40GB outbound data transfer)
  • Amazon Elastic Transcoder: $0.90 (assuming 60 minutes of video transcoding)
  • AWS Lambda:
    • Lambda for segmenting: $0.001
    • Lambda for merging: $0.001
    • Total: $0.002
  • Amazon SQS: $0.004 (assuming 4,000 requests)
  • Amazon EC2 On-Demand (g4dn.xlarge):
    • 3 hours * $0.526/hour = $1.578
  • Amazon EC2 Spot (g4dn.xlarge):
    • The cost will vary but assuming a 70% discount on the on-demand rate:
    • 3 hours * $0.1578/hour = $0.4734

Total On-Demand cost: $2.71

Total Spot cost: $1.61

Note: These costs are estimates based on the mentioned assumptions and the AWS rates at the time of writing. Actual costs may vary depending on usage, processing duration, and updated AWS rates.

The Stunning Results of Colorization

High-quality colorization results breathe new life into older black and white content. Below is an example of a video that has been colorized using the aforementioned process:
