convert h264 to h265

H.264 or Advanced Video Coding (AVC) is one of the most common media codecs for video recording, compression, and distribution. It was created to provide a standard for providing high-quality video at very low bitrates compared to previous standards like H.263. Then enters H.265 or High Efficiency Video Coding (HEVC), which is a more improved video compression standard that succeeds AVC.

H.265 helps to achieve 25-50% better data compression at the same quality or bitrate. As such, the HEVC codec proves very superior over H.264, and to get H.265 files from H.264, there is a need to seek the services of a video converter. Consequently, this article takes on the mandate of presenting you with the best ways to convert H264 to H265 without quality loss.

H.264 (AVC) vs H.265 (HEVC)

  • Compression Ratio & Bandwidth: H.264 or AVC is a leading video compression standard for HD digital video content and the successor, H.265 or HEVC, brings even more efficiency, thereby achieving a higher compression ratio, up to 50% better. As a result of high compression, the H.265 codec reduces the bitrate and the overall file size, resulting in a lower bandwidth video compared to H.264.
  • File Size: Taking into account that H.265 realizes a smaller bitrate at the same quality as an H.264 video, the overall file size of an H.265 is way smaller compared to the H.264 file equivalent. Specifically, H.265 can account for a 1-3X smaller video file than an H.264 encoded one.
  • Video Quality: Video quality is usually determined by various factors including the bitrate and as mentioned, H.265 keeps a smaller bitrate footprint when compared to H.264. As such, if both H265 and H264 were to rock the same bitrate, expect H.265 to have a higher quality for the final video.
