Why generic encoding is costing you viewers (and money)

Streaming quality isn’t just about resolution, it’s about retention. According to a Conviva report, even a 1% increase in buffering leads to a 3% drop in engagement. At scale, that’s thousands of frustrated viewers abandoning your platform and revenue slipping through the cracks.

That’s where Per-Title Encoding helps…

Instead of applying a one-size-fits-all bitrate ladder, per-title encoding dynamically adjusts the encoding recipe for each video based on its unique content complexity. High-action scenes get more bits for clarity, while simple animations or talking-head videos are compressed more efficiently. The result?

Per-title encoding for video streaming compared to standard encoding

  • Better quality: Viewers get crisper visuals and smoother playback, even on fluctuating networks.
  • Lower bandwidth costs: No wasted bits on unnecessary quality, cutting delivery costs without sacrificing experience.
  • Faster load times: Smaller file sizes mean quicker startup times, reducing abandonment rates.

For platforms balancing quality, cost, and scalability, per-title encoding isn’t just an upgrade, it’s a necessity.

Why static encoding falls short?

Think about a nature documentary and a fast-paced action film. One has slow, sweeping shots of landscapes; the other is packed with rapid motion and high detail. Yet, traditional static encoding treats them the same, applying a rigid set of bitrates and resolutions to every video, regardless of content.

That’s the problem.

Static encoding doesn’t adapt. It compresses some videos too much, stripping away fine details, while wasting unnecessary bits on simpler content. The result? A mix of blurry visuals, excessive buffering, and inflated costs—all of which degrade the user experience and burn through bandwidth.

Now, compare that to Per-Title encoding:

Static encoding is an outdated compromise. Per-Title Encoding doesn’t just improve efficiency it ensures every video is delivered in the best possible quality without wasting a single extra bit.

Metric Accuracy Speed Complexity Best For
PSNR (Peak Signal-to-Noise Ratio) Low (not perceptual) Fast Simple Quick quality checks and debugging
SSIM (Structural Similarity Index) Medium (closer to human vision) Moderate Moderate Measuring structural differences in videos
VMAF (Video Multi-Method Assessment Fusion) High (trained for human perception) Slower High (ML-based) Optimizing streaming quality and comparing codecs

     

What is Per-Title encoding?

Per-Title Encoding optimizes video quality by analyzing each file individually rather than applying a one-size-fits-all encoding ladder. High-action scenes receive the necessary bitrate to maintain clarity, while static or low-motion content is compressed more efficiently to reduce bandwidth usage. This approach ensures the best possible viewing experience without unnecessary data waste.

Steps in Per-Title Encoding

  1. Content analysis

Per-title encoding starts by analyzing the unique characteristics of a video—motion complexity, texture details, and scene variations. Machine learning models evaluate how much detail each scene requires, ensuring that action-heavy sequences get more bits for clarity while static or low-motion scenes are compressed efficiently without visible quality loss.

  1. Custom bitrate ladder creation

Unlike traditional encoding, which applies a fixed bitrate ladder to every video, per-title encoding dynamically generates an optimized set of renditions based on the content's complexity. High-detail videos receive higher bitrates where needed, while simpler content is encoded at lower bitrates to reduce unnecessary data usage—all while maintaining visual quality.

  1. Adaptive streaming

With an optimized bitrate ladder in place, adaptive bitrate streaming (ABR) ensures that viewers receive the best possible quality for their network conditions. As internet speeds fluctuate, the player seamlessly switches between renditions, reducing buffering and improving playback stability without sacrificing quality.

Benefits of per-title encoding

  • Superior video quality: Encoding parameters are fine-tuned for each video, reducing compression artifacts and preserving clarity. Fast-motion scenes get the extra bits they need, while simpler content avoids unnecessary bloat.
  • Smarter bandwidth usage: By encoding at the lowest bitrate that maintains quality, per-title encoding minimizes data consumption, ensuring smooth playback even in low-bandwidth conditions.
  • Lower storage costs: More efficient compression means smaller file sizes, reducing storage overhead and cutting down on long-term costs.
  • Seamless cross-device performance: Videos are optimized for a variety of screens, from mobile devices to smart TVs, delivering the best possible quality without requiring manual adjustments.
  • Better viewer experience & retention: Reduced buffering, faster startup times, and consistently high-quality playback keep viewers engaged, improving satisfaction and retention.

Real use case example

A streaming platform was bleeding money on bandwidth and millions wasted delivering bloated video files that didn’t need the extra data. Their one-size-fits-all encoding ladder meant slow-moving dramas were encoded as aggressively as high-speed action scenes, leading to inefficient streaming and rising costs.

After adopting per-title encoding, everything changed. By tailoring bitrate ladders to each video, they cut bandwidth costs by 30% while delivering sharper, more consistent quality. Viewers noticed the difference smoother playback, fewer buffering issues, and faster start times, even on weaker connections.

How FastPix uses content adaptive encoding (A smarter alternative)

Per-title encoding improves efficiency over static encoding, but it still applies a one-size-fits-all optimization per video. FastPix takes it further with Content Adaptive Encoding, a more dynamic and intelligent approach that continuously adjusts to both content complexity and real-world viewing conditions delivering better quality at lower bandwidth costs.

  1. Real-Time content analysis

Instead of encoding a video once and applying the same settings across all viewers, FastPix continuously analyzes content frame by frame. It assess motion intensity, texture complexity, and scene variations in real time, ensuring that each segment gets the optimal bitrate allocation.

  1. Dynamic bitrate adjustment

Rather than locking in a bitrate ladder at the time of encoding, FastPix adapts encoding decisions based on content characteristics and historical playback data. Fast-moving scenes are assigned higher bitrates for clarity, while simpler scenes receive lower bitrates without losing detail—minimizing waste while maximizing visual quality.

  1. Smarter adaptive streaming

FastPix integrates multi-layered bitrate optimization with its delivery pipeline. This means more efficient switching between quality levels based on a user’s device, screen resolution, and network conditions. FastPix optimizes throughout the entire streaming workflow reducing buffering, improving QoE (Quality of Experience), and lowering bandwidth costs.

While per-title encoding was a step forward, it still applies a static optimization per video. FastPix’s Content Adaptive Encoding goes further by making encoding decisions dynamically and continuously, ensuring the best possible balance of quality, efficiency, and cost savings without requiring manual intervention or guesswork.

Wrapping it up…

Static encoding wastes bandwidth and lowers quality. Per-title encoding improved efficiency, but FastPix’s Content Adaptive Encoding goes further—dynamically optimizing every frame for the best quality at the lowest cost. Smarter compression, real-time adjustments, and better streaming. Do check out our features section to know more on what we provide.
