A budget Nvidia card for H.265 hardware encoding
I am considering buying a Nvidia GPU for a sole purpose of hardware hevc encoding. Can somebody please recommend a model, i.e. sold on Amazon, that would nicely work, yet not ruin ones budget? I am not a gamer so there will be no other use outside video encoding/editing area.
From the software side I am specifically looking for a card that would allow the encoding using:
1. TMPGEnc Video Mastering Works 6
2. Ffmpeg/avconv under Linux
For example, I found this card on Amazon; ASUS GeForce GTX 970 for a ca $230
Is it going to work with the said software and if yes, what sort of acceleration in encoding I may expect comparing to a purely cpu encoding based on FX-6100 at 3300?
Why need a Graphic card for H.265 hardware encoding
H.265 is the new compression standard which offers good quality but small file size when comparing with the H.264, therefore, you can get great benefits by encoding H.264 or other video to H.265. There are many different tools and utilities to encode HEVC, however, the slow encoding speed can easily run out of your patience. Fortunately, you can largely accelerate H.265 encoding speed by taking full advantage of the hardware accelerated encoding technology offered by some Nvidia Graphic card. The following article will recommend a good and cheaper Nvidia Graphic cards with H.265 hardware encoding acceleration when using the specific H.265 encoding software.

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.
