In 2020, Coursera saw a massive surge in video traffic as online learning exploded. Their initial video setup basic cloud storage and a CDN worked fine at first. But as millions of students streamed lectures, buffering complaints surged. Mobile users struggled with poor quality, and storage costs skyrocketed. Engineers spent weeks manually adjusting encoding settings, trying to optimize streams.
The mistake? Treating video like a static file. Unlike images, video requires adaptive encoding, optimized delivery, and real-time adjustments to work seamlessly. Without the right setup, every view adds hidden costs, and every glitch frustrates users.
Coursera eventually reworked their video pipeline, shifting to AI-driven encoding and multi-CDN delivery to keep up with demand. But most companies don’t have the resources to build custom solutions from scratch.
Here’s why video at scale breaks and how to fix it before it slows you down.
A fitness streaming platform ran into major performance issues as their user base grew. Early on, their engineering team stored videos in Amazon S3 and relied on a standard CDN, assuming video files could be handled like images or PDFs. But as thousands of users streamed workouts simultaneously, buffering complaints spiked, costs soared, and engineering time was consumed by endless performance fixes.
The problem? Video isn’t static. Unlike an image that loads once, video needs adaptive encoding, optimized delivery, and efficient caching to work at scale. Every inefficiency whether in storage, retrieval, or playback multiplies as viewership increases.
For this platform, the consequences were immediate:
How they fixed it
The result? Lower costs, fewer buffering complaints, and a seamless viewing experience all without adding engineering overhead.
A live sports streaming platform faced a surge in user complaints some viewers struggled with buffering, while others were stuck with blurry, low-quality streams despite having high-speed internet. The platform had been delivering a single bitrate video to all users, assuming that one high-quality stream would be enough. But video consumption doesn’t work that way.
Why one-size-fits-all streaming fails
Not all viewers have the same network speed, device capability, or bandwidth availability. A 4K stream might look great on fiber internet but fail completely on mobile data, causing frustration and stream drop-offs. Meanwhile, a low-bitrate stream might load instantly but ruin the experience for users on fast connections.
For this streaming platform, the problems were clear:
The solution
The result? Higher viewer retention, fewer complaints, and a premium streaming experience across all networks.
A news streaming platform covering live events faced a critical issue breaking news videos took too long to process, delaying their ability to publish real-time updates. Their engineers had built a DIY cloud encoding pipeline, assuming standard compute instances could handle the workload. But as viewership spiked, encoding jobs piled up, CPU utilization maxed out, and video processing times stretched from minutes to hours.
Why encoding bottlenecks kill performance
Raw video files are massive and must be compressed, optimized, and converted into multiple formats before they can be streamed efficiently. Without an optimized encoding pipeline, video platforms experience:
For this news platform, missing a story window due to slow encoding meant losing viewers to competitors who could publish in real time.
The solution
The result? Real-time publishing, lower costs, and a seamless live streaming experience.
A large media archive struggled to keep up with content retrieval as their video library grew to hundreds of thousands of hours. Journalists and researchers often spent hours manually searching for relevant footage, slowing down their workflows and delaying content production. The reason? Their platform lacked structured metadata—videos were stored with generic filenames, making search and categorization a nightmare.
Why bad metadata breaks video platforms
Without structured metadata, video content becomes a black box difficult to organize, search, and retrieve. This leads to:
For this media company, the lack of automated tagging and structured indexing meant their massive video archive was effectively unusable at scale.
How they fixed it
The result? Faster content production, streamlined workflows, and a more intelligent video library.
A subscription-based video platform found itself stuck. Initially, they built their infrastructure using AWS Media Services, assuming it would scale effortlessly. But as their user base grew, so did their AWS bill hidden data transfer fees, unpredictable pricing, and the cost of managing multiple AWS services became overwhelming. Worse, their entire video workflow was locked into AWS, making it nearly impossible to migrate without a massive engineering effort.
Why fragmented tech stacks create chaos
Many teams start with off-the-shelf cloud services, integrating separate tools for encoding, storage, streaming, AI-based tagging, and analytics. At first, it works. But as the platform scales, the downsides become clear:
For this video platform, each new feature required navigating AWS’s fragmented services, leading to a bloated stack that slowed down innovation instead of enabling it.
The solution
The result? Lower costs, greater flexibility, and the ability to scale without AWS dictating their roadmap.
Most video issues don’t start big they show up as slow load times, inconsistent quality, or unexpected costs. and by the time they do, your team’s already stuck firefighting. the fix isn’t patching together more tools. it’s rethinking how video is handled from the start.

Video encoding plays a crucial role in reducing streaming latency. Poorly optimized encoding settings can introduce delays as videos need to be processed before playback. Real-time encoding techniques, such as GPU acceleration and just-in-time encoding, help minimize latency by rapidly compressing and converting videos into multiple formats on the fly.
Several factors influence video playback performance, including adaptive bitrate streaming (ABR), caching strategies, and network optimization techniques. A well-optimized video player should automatically adjust resolution based on available bandwidth, minimize buffering through predictive preloading, and use error correction mechanisms to handle packet loss.
Video files consume massive amounts of storage, and an inefficient storage strategy can lead to excessive costs. Tiered storage systems, where frequently accessed videos are kept in high-speed storage while archived content is moved to lower-cost cold storage, help optimize costs. Additionally, efficient metadata indexing ensures that videos are easily retrievable, reducing redundant storage usage.
Scaling a video platform involves overcoming issues like encoding bottlenecks, high storage costs, adaptive delivery across various devices, and network congestion. Without a well-architected video pipeline, platforms face rising operational costs and poor user experience due to buffering and quality degradation.
Businesses can optimize global video streaming by using a multi-CDN approach, leveraging edge caching to reduce latency, and implementing AI-driven adaptive streaming. Additionally, supporting regional encoding formats and optimizing for different network conditions ensures a seamless viewing experience across diverse geographies.
