Why people encode media to H.265/HEVC?
H.265 is the new video compression standard after H.264, it has better compression performance and lower bandwidth ultization ratio. When compared with H.264, the greatest strength of H.265 is that it has a higher compression ratio, in other words, at the same quality of codding, H.265 can save around 50% of the bit rate, and the coding efficiency can be doubled than H. 264, as H.265 provides more different tools to reduce the bit rate. In one word, encoding media to H.265/HEVC can not only help to substantially reduce the file size of your video library but also make streaming between devices more easier.
The long time to encode H.265/HEVC
The high efficiency of H.265 comes with a cost: complexity. H.265 is far more difficult to encode as a result of its complexity, and can require up to 10 times the compute power to encode at the same speed as H.264. You' ll find your videos take many times longer to encode H.265 than other codecs.
Fastest Nvidia encoder for H.265/HEVC encoding
To fix the H.265 slow encoding issue, Pavtube studio has recently update its great media conversion tool - Pavtube Video Converter Ultimate and other Windows software with perfect support 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.
Tips: Following diagram has listed Nvidia Graphic technolgy that supports H.265 encoding:
| GPU | H.265 (HEVC) YUV 4:2:0 | H.265 (HEVC) YUV 4:4:4 | H.265 (HEVC) LOSSLESS | |||
| MAX Color | MAX Res. | MAX Color | MAX Res. | MAX Color | MAX Res. | |
| Maxwell (GM206) | 8-bit | 4096 x 4096 | 8-bit | 4096 x 4096 | 8-bit | 4096 x 4096 |
| Pascal | 10-bit | 8192 x 8192** | 10-bit | 8192 x 8192** | 10-bit | 8192 x 8192** |

How to Encode Video/Blu-ray/DVD to H.265/HEVC with the Fastest Nvidia Encoder?
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.
