FFMPEG: H.265 (HEVC) Video Encoding with VCNVENC (yuv420) at 800Mbps

FFMPEG: H.265 (HEVC) Video Encoding with VCNVENC (yuv420) 800Mbps

In this article, we will discuss how to use FFMPEG to encode H.265 (HEVC) video with a target bitrate of 800Mbps using the VCNVENC codec with yuv420 pixel format. This is a detailed guide that covers the key concepts of H.265 encoding, subtitles, and more. The content is structured using HTML headings (H2, H3) and paragraphs (

What is H.265 (HEVC)?

H.265, also known as High Efficiency Video Coding (HEVC), is a video compression standard that offers better compression efficiency compared to its predecessor, H.264. H.265 provides up to 50% better data compression at the same level of video quality, making it an ideal choice for high-bitrate video applications such as 4K and 8K video.

Why use VCNVENC for H.265 encoding?

VCNVENC is a hardware-accelerated video encoding library provided by Intel for use with their integrated graphics processors (IGPs). VCNVENC supports H.265 encoding and provides better performance and lower power consumption compared to software-based encoding solutions. In this guide, we will use VCNVENC for H.265 encoding with a target bitrate of 800Mbps.

Encoding H.265 video with FFMPEG

FFMPEG is a free and open-source multimedia framework that can be used for video and audio encoding, decoding, and processing. To encode H.265 video with FFMPEG, we need to use the following command:

Here, we are using the libvcn\_nvcuvid codec for H.265 encoding with the yuv420 pixel format. The target bitrate is set to 800Mbps using the -b:v flag.

Adding subtitles to H.265 video

To add subtitles to H.265 video, we can use the following command:

Here, we are using the subtitles filter to add subtitles from the subtitle.srt file to the output video.
