The Power of AI and Human Collaboration in Media Content Analysis
In today’s world binge watching has become a way of life not just for Gen-Z but also for many baby boomers. Viewers are watching more content than ever. In particular, Over-The-Top (OTT) and Video-On-Demand (VOD) platforms provide a rich selection of content choices anytime, anywhere, and on any screen. With proliferating content volumes, media companies are facing challenges in preparing and managing their content. This is crucial to provide a high-quality viewing experience and better monetizing content.
Some of the use cases involved are,
Finding opening of credits, Intro start, Intro end, recap start, recap end and other video segments
Choosing the right spots to insert advertisements to ensure logical pause for users
Creating automated personalized trailers by getting interesting themes from videos
Identify audio and video synchronization issues
While these approaches were traditionally handled by large teams of trained human workforces, many AI based approaches have evolved such as Amazon Rekognition’s video segmentation API. AI models are getting better at addressing above mentioned use cases, but they are typically pre-trained on a different type of content and may not be accurate for your content library. So, what if we use AI enabled human in the loop approach to reduce cost and improve accuracy of video segmentation tasks.
In our approach, the AI based APIs can provide weaker labels to detect video segments and send for review to be trained human reviewers for creating picture perfect segments. The approach tremendously improves your media content understanding and helps generate ground truth to fine-tune AI models. Below is workflow of end-2-end solution,
Raw media content is uploaded to Amazon S3 cloud storage. The content may need to be preprocessed or transcoded to make it suitable for streaming platform (e.g convert to .mp4, upsample or downsample)
AWS Elemental MediaConvert transcodes file-based content into live stream assets quickly and reliably. Convert content libraries of any size for broadcast and streaming. Media files are transcoded to .mp4 format
Amazon Rekognition Video provides an API that identifies useful segments of video, such as black frames and end credits.
Objectways has developed a Video segmentation annotator custom workflow with SageMaker Ground Truth labeling service that can ingest labels from Amazon Rekognition. Optionally, you can skip step#3 if you want to create your own labels for training custom ML model or applying directly to your content.
The content may have privacy and digitial rights management requirements and protection. The Objectway’s Video Segmentaton tool also supports Digital Rights Management provider integration to ensure only authorized analyst can look at the content. Moreover, the content analysts operate out of SOC2 TYPE2 compliant facilities where no downloads or screen capture are allowed.
The media analysts at Objectways’ are experts in content understanding and video segmentation labeling for a variety of use cases. Depending on your accuracy requirements, each video can be reviewed or annotated by two independent analysts and segment time codes difference thresholds are used for weeding out human bias (e.g., out of consensus if time code differs by 5 milliseconds). The out of consensus labels can be adjudicated by senior quality analyst to provide higher quality guarantees.
The Objectways Media analyst team provides throughput and quality gurantees and continues to deliver daily throughtput depending on your business needs. The segmented content labels are then saved to Amazon S3 as JSON manifest format and can be directly ingested into your Media streaming platform.
Conclusion
Artificial intelligence (AI) has become ubiquitous in Media and Entertainment to improve content understanding to increase user engagement and also drive ad revenue. The AI enabled Human in the loop approach outlined is best of breed solution to reduce the human cost and provide highest quality. The approach can be also extended to other use cases such as content moderation, ad placement and personalized trailer generation.

From Data to Insights Developing a Solid Annotation Strategy
In the arena of system learning, information is king. But, without a solid annotation strategy, your data is just a pile of unorganized information. Annotation is the process of labeling and categorizing data, making it possible for machines to understand and learn from it. A well-annotated dataset is the foundation of a successful machine-learning project, enabling models to make accurate predictions and drive business insights.
The Importance of Annotation
Annotation is a crucial step in the machine-learning process, and its importance cannot be overstated. Here are a few reasons why annotation matters:
- Improved model accuracy: High-quality annotations enable models to learn from data and make accurate predictions. Without accurate annotations, models may learn incorrect patterns or biases, leading to poor performance.
- Reduced bias: Well-annotated data helps reduce bias in models, ensuring they are fair and inclusive. Biased models can perpetuate existing social inequalities, making annotation a critical step in developing ethical AI.
- Increased efficiency: Annotated data enables models to learn faster and require less training data. This reduces the time and resources required for training, making the machine-learning process more efficient.
Challenges of Annotation
Annotation is a complex process, and several challenges can arise when developing an annotation strategy. Here are a few common challenges:
- Data quality: Poor data quality can lead to inaccurate annotations, which can negatively impact model performance. Noisy or inconsistent data can make annotation difficult, leading to errors and inconsistencies.
- Scalability: Large datasets require significant annotation efforts, which can be time-consuming and costly. As datasets grow, annotation becomes increasingly complex, requiring specialized tools and expertise.
- Consistency: Ensuring consistency across annotations is crucial, but it can be challenging, especially with large teams. Inconsistent annotations can lead to biased models, making consistency a critical aspect of annotation.
The Importance of Dataset Size in Data Annotation
When it comes to data annotation, understanding the size of your dataset is crucial for success.
