What is HEVC/H.265?
High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is a video compression standard, one of several potential successors to the widely used AVC (H.264 or MPEG-4 Part 10). In comparison to AVC, HEVC offers about double the data compression ratio at the same level of video quality, or substantially improved video quality at the same bit rate. It supports resolutions up to 8192×4320, including 8K UHD.
What does HEVC mean for 4K videos?
With an increasing growth of video streaming on the Internet over popular websites such as Netflix and YouTube, and with 4K cameras gaining new ground in the market, a considerable amount of storage and bandwidth is required. HEVC promises a 50% storage reduction as its algorithm uses efficient coding by encoding video at the lowest possible bit rate while maintaining a high image quality level.
How to encode or decode 4K HEVC videos at super fast speed?
Do you want to encode your 4K AVCHD captured by Panasonic/Sony/Canon, 4K MP4/MOV shot by DJI Mavic Air/Phantom, 4K videos downloaded from Youtube, and other to 4K HEVC for saving storage space and bandwidth? Or, do you want to decode 4K HEVC to a compatible format to fix playback issue? The following hardware-accelerated 4K HEVC transcoder can process 4K HEVC encoding and decoding quickly without hassle.
Pavtube Video Converter Ultimate | for Mac supports for H.265/HEVC encoding acceleration. As long as your PC are running on a CUDA-enabled Graphics card, the H.265/HEVC encoding speed of Pavtube Video Converter Ultimate can be accelerated about 30X faster than before.
