H.265 VS H.264- Difference Between HEVC and H.264

Have no idea what’s the difference between H.264 and H.265 as a lot of posts saying that this two compression codec look the same, the only difference is that the H.265 file size is much smaller. The following part will offer you a detailed comparison of H.265 and H.264. You will have a clear idea of what’s HEVC and H.264 and also the obvious difference between H.265 and H.264.

Definition of H.264 and H.265

What’s H.265?

H.265/HEVC or High Efficiency Video Codec, which is first appeared in 2013 as a true successor to H.264. For this reason, HEVC is also known as H.265, or MPEG-H Part 2.

What’s H.264?

H.264 is a popular standard for high definition digital video, and for good reason. A codec based on the H.264 standard compresses a digital video file so that it only uses half the space of MPEG-2 (the DVD standard), to deliver the same quality video. This means you can enjoy stunning HD video the way it was meant to be seen without sacrificing speed or performance.

HEVC VS H.264: Difference between H.265 and H.264

HEVC’s main advantage over H.264 is that it offers roughly double the compression ratio for the same quality. This means that a video file encoded with HEVC can occupy half the space of its H.264 equivalent with no noticeable change in quality, or the same amount of space with improved quality.

Since H.265/HEVC has some many great benefits when compared with H.264. In addition, it is also the trend of future compression codec as more and more video are delivered with 4K resolution video. Therefore, for those people who wish to compress HD video without damaging the file quality to save more space, it would be a good option for you to convert video to H.265, in addition, you can also get better visual quality when encoding SD video to H.265/HEVC codec. Not knowing how to convert video to H.265, all you need is a powerful H.265 encoder software.

Best tool to encode video to H.265

After a lot of online testing and comparison, we finally settle on Pavtube Video Converter Ultimate.
