H.264 vs. H.265 (HEVC): Which Codec Should You Choose?

 When compressing or transcoding video files, you will almost always have to choose between H.264 (AVC) and H.265 (HEVC). Understanding the difference can save you massive amounts of storage space.

• H.264 (Standard AVC): This is the king of compatibility. Virtually every device on earth—from old smartphones to modern smart TVs—can play H.264 files flawlessly.

• H.265 (Modern HEVC): This is the future of video compression. It offers the exact same visual quality as H.264 but cuts the file size roughly in half.

If you are creating videos for older devices or web players, stick with H.264. If you want to archive large 4K video projects on your hard drive without running out of space, choose H.265.
