More and more people prefer to encode media to H.265/HEVC codec, why? High Efficiency Video Coding (HEVC), or H.265, is a video compression standard designed to substantially improve coding efficiency when compared to its precedent, the Advanced Video Coding (AVC), or H.264. 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. In the current market, more and more devices add support for playing HEVC videos, like iPhone X, Apple TV 4K and more.
You will find that H.265 codec encoding time is much longer than other codes especially when you are using a old dual-core desktop to do the encoding work. In the current market, there are dozens of video converter programs that support hardware acceleration techs for encoding HEVC, but few of them can really satisfy you. Fortunately, I will share the best one with you which allows you to speed up H.265 encoding speed to 30x. Can't wait? Here we go.

How to Use Pavtube Video Converter Ultimate for fastest H.265 Encoding on Nvidia GeForce Graphic Cards?
Step 1: Import video or load Blu-ray/DVD disc into the program.
Start the program on your computer, click "File" > "Add Video/Audio" to import digital file formats into the program, for load Blu-ray or DVD disc, insert your DVD disc into your computer's optical drive and your Blu-ray disc into an external Blu-ray drive, click "File" > "Load from Disc" to load Blu-ray/DVD disc into the program.
Step 2: Enable GPU Encode Acceleration.
Click "Tools" > "Options", in the opened "Options" window, click "Acceleration" menu, then check "Enable GPU Encode Acceleration" otpion so that the program will accelerate converion speed when encoding video/Blu-ray/DVD to H.265/HEVC codec.
Step 3: Output H.265 MP4 or MKV format.
Click "Format" drop-down bar, scroll down to select "Common Video" > "H.265 Video(*.MP4)" as the output file format.
For outputting H.265 MKV format, select "HD Video" > "MKV HD Video(*.mp4)" to output, then hit "Settings" on the main interface to open "Profile Settings" window, under Video settings panel, click "Codec" drop-down selection, choose "H.265" as your final output file codec.
Step 4. Adjust output file parameters (Optional)
You are allowed to adjust video and audio parameters if you are not satisfied with the default settings. Presets like size, bitrate, frame rate, audio channels, etc. can be customized in your own way.
Step 5: Begin the H.265/HECV codec encoding process.
After all settings is completed, hit right-bottom "Convert" button to begin the conversion from video/Blu-ray/DVD to H.265/HEVC encoding process.
When the conversion is completed, you will get a perfect quality H.265/HEVC file with smaller file size for smoothly viewing and streaming on different devices.
