Which video codec family does YouTube recommend?

• A. HEVC
• B. VP9
• C. H.264
• D. MPEG-2

Answer: (C)

The main idea is universal compatibility for uploads. H.264 (AVC) is the most widely supported video codec across devices, browsers, and platforms, and it works smoothly with the common MP4 container and AAC audio. Because of this broad support, YouTube recommends using H.264 as the baseline for uploads to minimize playback issues and ensure efficient decoding on both older and newer hardware. HEVC (H.265) can offer better compression but isn’t as universally supported across all devices and browsers, which can lead to playback problems for some viewers. MPEG-2 is outdated for modern streaming and provides much less efficiency. VP9 is used by YouTube for playback and can be efficient, but for uploads, H.264 remains the standard recommendation due to its widest compatibility and reliable processing.
