Codecs & Compression
Codecs are short for compressor-decompressor or coder-decoder and they are critical part of any digital media. Without compression most media files would be huge and make current Web practically impossible. The challenge is to balance compression and quality in a way that’s efficient, fast, and visually acceptable.
Codecs are a set of complex mathematical algorithms, that compress a media file to a manageable size and they are everywhere. They can be lossless or lossy. An uncompressed 24-bit 1920×1080 image, like BMP, is ~6MB (1920 × 1080 × 3 = 6,220,800 bytes ≈ 5.93 MB). That same image compressed using JPEG can be as little as 200KB, that’s 30X reduction, depending on quality and complexity of the image. This is down side of most compression algorithms – reduced quality, which – depending on the complexity of the image – can create compression artifacts.
They can be hardware(GPUs or other embedded processor) or software(CPU) accelerated.
- Hardware Acceleration: Hardware acceleration uses GPUs or specialized processors to handle encoding and decoding media files, offloading these tasks from the main CPU. This allows the CPU to manage other tasks efficiently. GPUs excel at parallel processing, crucial for video compression and decompression, enabling smoother playback and faster processing of high-definition video. Hardware acceleration is preferred for high-performance tasks.
- Software Acceleration: Software acceleration uses CPUs for encoding and decoding videos, offering flexibility and optimization through multithreading and advanced algorithms. A well-optimized codec can efficiently use a CPU’s architecture. Modern devices often have dedicated video processing units in GPUs, similar to dedicated video chips for CPUs. Software acceleration is viable for devices with limited hardware resources or cost constraints, leveraging modern hardware capabilities.
Audio/Video Codecs
- H.264 (AVC): The most widely used video codec in the world today, H.264, also known as Advanced Video Coding (AVC), has become the standard for a vast array of digital video applications. Its popularity stems from its ability to deliver high-quality video at relatively low bitrates, making it ideal for streaming services such as YouTube, Netflix, and various live broadcasting platforms.
- H.265 (HEVC): Successor to H.264. Offers ~50% better compression at the same quality, but needs more compute power. Great for 4K and HDR, but not as universally supported.
- ProRes: Apple’s intermediate codec. High quality, designed for editing. Very lightly compressed. Huge files, but fast playback and less taxing on editing software.
- VP9: Open-source alternative to H.265 by Google. Used on YouTube. Good quality and compression, especially for web.
- AV1: Modern, open-source, royalty-free codec. Excellent compression, better than H.265. Not yet fully adopted due to high encoding complexity.
- AAC (Advanced Audio Coding): AAC is a modern audio compression format that succeeds MP3, offering better sound quality at the same bitrate. A 128 kbps AAC file sounds clearer than an MP3 due to efficient encoding and improved frequency handling. It’s widely used in streaming services like Apple Music and Spotify, and in mobile devices, thanks to its broad compatibility and efficient storage.
- MP3: Known for revolutionizing digital music in the late 1990s, MP3 uses lossy compression to reduce file sizes, ideal for portable players. However, it sacrifices audio fidelity, leading to artifacts at lower bitrates. While still supported, newer codecs offer better quality at similar sizes, making MP3 outdated in quality-per-bitrate.
- FLAC (Free Lossless Audio Codec): FLAC compresses audio without quality loss, retaining every bit of the original recording. It’s favored by audiophiles for archiving and high-fidelity playback, offering perfect sound reproduction at about half the size of uncompressed audio. Many music stores now offer FLAC for the best audio experience.
- Opus: An open-source codec designed for versatility, Opus excels in real-time communication like Zoom and Discord due to low-latency and adaptive bitrate. It handles everything from speech to full-band stereo music, making it ideal for modern communication and streaming.
- WAV (Pulse-Code Modulation): PCM represents analog audio in digital form, capturing uncompressed audio with unmatched fidelity. Used in WAV and AIFF files, PCM is a staple in studios for editing and mastering due to its large file size and pure sound quality, though impractical for everyday use.
Quality
- Lossless: Every bit of data is preserved, ensuring that the original file can be perfectly reconstructed from the compressed version. This type of compression is ideal for situations where maintaining the integrity of the data is crucial, such as in professional production environments, detailed editing processes, and long-term archiving. For example, formats like FLAC for audio and PNG for images are popular choices because they retain all the original information, making them suitable for high-quality applications where no loss of detail is acceptable.
- Lossy: This method discards data that is deemed imperceptible to the human senses, based on sophisticated models of human perception. By removing these less noticeable elements, lossy compression achieves significantly smaller file sizes, making it highly efficient for delivery over the internet or for storage where space is limited. However, because some data is permanently removed, lossy formats like MP3 for audio and JPEG for images are not suitable for re-editing or situations where the highest fidelity is required. They are best used in scenarios where convenience and speed are prioritized over perfect accuracy, such as streaming music or sharing photos online.
- Subjective Quality: Human perception. This is about whether it looks or sounds good. An editor may spot, banding, or aliasing.
- Objective Quality: Measurable using algorithms like PSNR (Peak Signal-to-Noise Ratio), SSIM (Structural Similarity Index), or VMAF (Video Multimethod Assessment Fusion). Nvidia has free ICAT(Image Comparison Tool). These are used to compare original vs. compressed versions and give a numerical score.
- Trade-offs: Higher compression lowers bitrate, which saves storage or bandwidth, but can introduce artifacts that lower perceived quality.
Compression Artifacts
When evaluating compressed media, quality is not just about clarity—it’s about how close it appears to the original, and how natural it feels to a human viewer.
- Blocking: Square patterns in flat areas (common in JPEG, H.264).
- Banding: Visible steps in gradients due to bit-depth loss.
- Mosquito noise: Haloing around sharp edges.
- Audio artifacts: Warbling, metallic echoes, muffled transients in compressed audio.
Resolution & Display
- Resolution: Refers to the number of pixels in an image or display. Common resolutions include 1080p (1920×1080 pixels) and 4K (3840×2160 pixels). Higher resolutions provide sharper images but result in larger file sizes.
- Aspect Ratios: The proportional relationship between width and height of a display or image. Common aspect ratios include 16:9 (widescreen), 4:3 (traditional TV), and 21:9 (ultra-wide) and 9:16 vertical frame shot on phones (Reels, Shorts). Mismatched aspect ratios can cause black bars on the screen.Â
- Pixel Aspect Ratio: The shape of individual pixels. Mismatches with the display aspect ratio can lead to image stretching or distortion.
- Frame Rates: The number of frames displayed per second. Standard frame rates include 24 fps (cinematic), 30 fps (common for TV), and 60 fps or higher (ultra-smooth for gaming and sports).
- Refresh Rate: How often a display updates per second, measured in Hertz (Hz). Can also be understood as how many new frames in can be drawn on the screen. Most screens meant for content consumption of all sizes refresh at least at 60 Hz. Newer ones do 120. More games and UI
- HDR vs. SDR: HDR (High Dynamic Range) offers greater contrast and color richness compared to SDR (Standard Dynamic Range), enhancing visual quality. This means darker blacks and brighter whites. To view HDR content first you need a screen that supports and HDR color mastered video, encoded by codec that supports HDR like H265.
