Debunking the Myth that Better Video Quality Costs More
Are you looking to deliver sharper video without increasing bandwidth costs?
Do you want consistent playback across every device and network? And are you trying to achieve all of these objectives without compromising operational efficiency? Well, you’re at the right place. We’ll help you achieve all these goals together. Keep reading.
High-quality video delivery isn't just about increasing bitrate or investing in extensive infrastructure. Video streaming services’ platforms must constantly balance visual quality, bandwidth consumption, storage requirements, and content delivery costs. Achieving that balance depends largely on how efficiently video data is encoded, stored, and transmitted.
While higher bitrates generally improve picture quality, they also increase bandwidth usage, storage requirements, and operational costs. On the other hand, over-compressing a video can lead to loss of detail, pixelation, and inconsistent playback, especially during high-motion scenes.
So, how can you improve video quality without increasing costs? The answer lies in multi-pass encoding capabilities offered by MultiTV Streamline.
As a leading video encoding platform, MultiTV Streamline combines multi-pass encoding with intelligent bitrate allocation to help streaming platforms deliver high-quality video while optimising bandwidth, storage, and content delivery costs.
Let’s have a closer look.
A video encoding technique that processes a video in more than one pass before generating the final output is known as multi-pass encoding.
In the first stage, the encoder analyses the entire video to comprehend the scene complexity, motion, textures, and inter-frame changes. So instead of generating the final output right away, it collects the information needed to make better encoding decisions.
Next, the encoder uses the generated insights to distribute bitrate more thoughtfully and intelligently. For example, complex scenes receive more data to preserve visual quality, while simpler scenes are compressed more efficiently without noticeably affecting the viewing experience.
In simple terms, multi-pass encoding focuses on using the available bitrate where it creates the greatest visual impact.
However, knowing how multi-pass encoding works is only half the picture. To truly appreciate its advantage, it's important to see how it differs from the traditional single-pass encoding approach.
How multi-pass encoding differs from single-pass encoding
Video optimization is crucial before it’s streamed on multiple platforms and devices.
The key difference lies in how bitrate allocation decisions are made.
Let’s understand this better:
When the encoder analyses and compresses the video simultaneously, it is single-pass encoding. Here, the encoder focuses only on the current frame, making bitrate decisions in real time. On the contrary, multi-pass encoding involves the analysis of complete video before beginning the compression process. This enables more informed bitrate decisions across different scenes.
Think of it like planning a road trip.
If you start driving without checking the route, you'll make decisions as situations appear.
But if you've already studied the map, you'll know where traffic usually builds up, where fuel stops are available, and which route is most efficient.
At a video encoding platform, like MultiTV, multi-pass encoding works in much the same way. Looking ahead helps it make better decisions.
| Single-Pass Encoding | Multi-Pass Encoding |
| Analyses and encodes simultaneously | Analyses first, then encodes |
| Faster processing | Longer processing time |
| Best suited for live streaming | Best suited for pre-recorded content |
| Makes instant bitrate decisions | Makes informed bitrate decisions |
| Prioritises speed | Prioritises quality and encoding efficiency |
How Does Multi-Pass Encoding Optimise Bitrate Allocation?
Every video demands unique treatment. For instance:
- An online lecture contains relatively little motion compared to a football match.
- A football match includes constant camera movement, changing lighting, thousands of spectators, and fast-paced action.
Now, if both of the videos receive the same bitrate, the results are not usually ideal. Complex scenes may not receive enough bitrate to preserve fine details, while simpler scenes often receive more bitrate than they actually need.
Here, multi-pass encoding solves this by allocating bitrate as per the scene complexity. It identifies which part of the video requires more data and where bitrate reduction can be done without noticeably affecting quality.
This smarter bitrate allocation, enabled by a video encoding platform like MultiTV Streamline, helps:
- Deliver better visual quality
- Optimise bandwidth usage
- Reduce storage and CDN costs
- Maintain consistent playback across devices and network conditions
Where multi-pass encoding delivers the most value
Since multi-pass encoding requires additional processing time, it adds the most value where video quality is more important than encoding speed.
OTT Platforms
There is an extensive content library management requirement with video streaming services like OTT platforms, allowing them to perform consistently across smartphones, tablets, laptops, and smart TVs.
Video-On Demand (VOD)
VOD assets are encoded once but viewed repeatedly. Unlike live content, it is streamed repeatedly over months or years. Investing more time in encoding often results in better picture quality and greater efficiency in the long run.
Broadcasters and Media Companies
For sports, entertainment, documentaries, catch-up TV, and archived content, multi-pass encoding helps preserve visual quality while preparing content for distribution across multiple platforms.
However, in live streaming, where speed is crucial, multi-pass encoding might not be the best option. This is because viewers probably don’t want to wait, and it requires fast video encoding behind the scenes. So yes, the solution to this is single-pass encoding.
Wrapping Up
In a nutshell, choosing the right encoding approach is the key to achieving your streaming goals, like lower cost with optimal delivery. It’s not always true that ensuring a better video quality requires higher bandwidth or bigger infrastructure investments. Sometimes, it takes smarter encoding decisions that optimize bitrate, reduce delivery costs, and maximize efficiency. MultiTV Streamline assists video streaming services in optimizing bitrate, lowering delivery costs, and providing consistently excellent viewing experiences.
