In this ultimate guide, we'll delve into the essentials of AV1, walk you through the conversion process, and share expert tips to ensure your videos look their best while being highly efficient. Whether you're a novice or a seasoned pro, this guide has something for everyone. Let's explore the future of video encoding together.

Part 1. What is MP4 & AV1 Formats

MP4 Format

MP4, or MPEG-4 Part 14, is a widely used digital multimedia container format. It supports video, audio, subtitles, and images, offering excellent compatibility, versatility, and efficient compression for streaming and storage across various devices and platforms.

AV1 Format

AV1, or AOMedia Video 1, is a cutting-edge video codec developed by the Alliance for Open Media. It provides superior compression and higher video quality compared to older codecs, is royalty-free, and supports high-resolution formats, making it ideal for efficient streaming and future-proof video applications.

Differences Between MP4 and AV1

Codec vs. Container:

  • MP4: A container format that can include various codecs for video (e.g., H.264), audio, and other data.
  • AV1: A video codec that can be used within various container formats (e.g., MP4, MKV).

Compression Efficiency:

  • MP4: Typically uses H.264 codec, which offers good but not the best compression efficiency.
  • AV1: Provides superior compression efficiency, reducing file sizes by about 30% more than H.264 without compromising quality.

Quality and Performance:

  • MP4 (H.264): Balances quality and file size effectively but can struggle with very high resolutions and modern streaming demands.
  • AV1: Excels in maintaining high quality at lower bitrates, supporting ultra-high-definition content with less bandwidth.

Understanding these formats and their differences is crucial for making informed decisions about video storage, streaming, and distribution, ensuring optimal performance and cost-efficiency in your media projects.
