HEVC (H.265) Video Encoding Realworld Example

High Efficiency Video Coding (HEVC) or H.265 as it’s also known is poised to be the successor to the popular H.264 video compression standard. It promises significant improvements to previous data compression standards and will support the 8K Ultra High Definition video standard (8192×4320 pixels).

But enough of the technical background, what does this mean to us regular users? To give an example, I recently shot some video using a GoPro Hero 4 Silver at 4K resolution (15FPS). This was then exported to a 3.55GB 1080p MPEG file using no compression. That file was then re-encoded using H.264. This process was repeated using H.265.

The results speak for themselves:

As you can see I was able to achieve an 82% reduction using H.264 and a whopping 93% using H.265. Remember this is of an uncompressed source, you won’t see anywhere near this if trying to apply H.265 to an already compress file.

No doubt this will have positive implications to video storage and streaming. In a country with poor broadband capabilities to the masses, this will at least have the potential to take some of the pain away.
