What Is AI Video Compression?

At its core, video compression aims to reduce the size of a video file without significantly compromising the viewing experience. Traditional systems accomplish this by using certain encoding standards, which specify which parts of the video data can be safely dropped or simplified. But as our demand for higher-quality videos grows, so does the need for smarter, more effective compression techniques – and that’s where AI starts to take over.

AI Video Compression leverages Machine Learning algorithms and Deep Learning models to further the possibilities of video compression. Rather than simply following predefined rules, AI systems can dynamically analyze video data, learn from it, and make informed decisions about what information is dispensable based on context and content. The result is an impressively compact video file that still provides a high-quality viewing experience, even with less data usage. AI Video Compression essentially breathes intelligence into the process, making it adaptable, flexible, and remarkably efficient, paving the way for the future of video streaming and content delivery.

Which Video Codecs Are Used Today?

Understanding codecs begins with their name, which combines “compression” and “decompression.” This encapsulates their primary function: to compress and decompress media files.

Video and audio codecs can employ either “lossy” or “lossless” compression methods. Lossy compression reduces file size by discarding some data, making the file smaller and more efficient. In contrast, lossless compression retains all the original data. Most video codecs fall into the lossy category.

There are three main types of codecs: delivery, intermediate, and acquisition.

Delivery Codecs: These are used for broadcasting and playback. Common examples include:

• H.264 (AVC)
• H.265 (HEVC)
• AV1
• VP9
• WMV

Intermediate Codecs: These are essential for video editing. Examples are:

• ProRes 422 and 4444
• DNxHR
• DNxHD
• CineForm

Acquisition Codecs: Used for capturing video, these include:

• ArriRaw
• Blackmagic Raw
• Redcode Raw

We often don’t realize the prevalence of codecs in our daily lives, from phone calls to the television broadcasts we watch. Television, in particular, is a continuous display of compression and decompression processes in action.

Shift To AI Video Compression

Prior to the emergence of AI, video compression heavily relied on conventional techniques. These methods, although effective to a certain extent, presented inherent challenges. They commonly employed lossy compression algorithms, which inevitably sacrificed a portion of video quality in pursuit of smaller file sizes. This compromise in quality could manifest as noticeable artifacts, such as blockiness or blurriness, especially when operating at lower bitrates.

Additionally, standardized codecs like H.264 predominantly monopolized the video compression landscape, which had enjoyed years of widespread usage. While these codecs were efficient for their era, they struggled to adapt to diverse content types and optimize for fluctuating network conditions.

Finally, traditional compression methods often lacked the adaptability and flexibility required to analyze and optimize video content intelligently. They tended to treat all content uniformly, leading to suboptimal outcomes for specific video types. Enter the AI revolution that’s reshaping video compression techniques in ways we couldn’t have envisioned before:

• Quality Retention. AI-driven video compression excels in maintaining video quality. It achieves this by employing advanced algorithms that selectively compress parts of the video while preserving critical details. As a result, viewers enjoy high-definition videos with minimal loss in visual clarity, ensuring a superior viewing experience.
• Faster Processing. Traditional video compression methods often require significant processing time, leading to delays in content delivery and potentially causing buffering issues. AI-driven compression’s intelligent algorithms optimize the process, reducing the time required to compress videos. This means that content can be prepared and delivered more swiftly, helping keep up with the modern demand of speed and accuracy.
• Reduced File Sizes. One of the standout advantages of AI video compression is its ability to significantly reduce file sizes without compromising quality. AI algorithms meticulously analyze the video content, identifying redundancies and non-essential data that can be safely removed. This results in smaller file sizes, which not only save storage space but also reduce the amount of bandwidth required for streaming. This translates into substantial cost savings concerning storage and data transfer for businesses and content platforms.
