Plug insCommon To choose the NVENC plugin in Media Encoder, in the format menu, select lt NVENCexport Performance quality notes 1 How much faster is NVENC export than Adobes built in Mainconcept H2. Depends on your PC system. On my test system, which is ordinary desktop PC with Intel i. K 4 core 3. 4. GHz, NVENC plugin is roughly 4x faster than Mainconcept. On a dual socket Xeon Ivy Bridge E system, NVENC would probably only be 2x faster in Media Encoder. How does the video quality compare Comparing similar settingsvideo bitrate, Mainconcept performs better at lower bitratesless artifacts. At medium high bitrates, NVENC is comparable to Mainconcept. How does NVENC export encode the videoThe plugin fetches video. Frames from the Adobe application, then converts the frames from YUV4. NV1. 2 surface format using host CPU. Then it passes the converted frames to the NVENC front end. From here, NVENC hardware takes over, and handles all aspects of the video compression. When NVENC hardware is done, it calls the plugin to output write the elementary bitstream to the selected filepath. NVENC hardware does NOT encode audio, nor does not multiplex the AVbitstreams this is still done in software on the host CPUThe NVENC hardware block has very little CPU overhead. But since video encoding is just 1 step in the entire Adobe rendering path, CPU usage will likely still be quite high when using NVENC plugin. Whats the maximum size video NVENC export can handleH2. High profile Level 5. Note the actual encoding speed will probably be less than 3. How fast is the NVENC export hardware in Kepler GPU Assuming the Adobe application host is infinitely fast i. NVENC hardware will encode High profile CABAC, 2 refframes, 1 bframe 1. At 3. 84. 0x. 21. That is still faster than a desktop PC. NVENC speed is generally same across the Kepler family the high end Geforce GTX Titan or GTX7. Geforce GTX6. 50, because all Kepler models share the same NVENC hardware block, which is totally separate and independent of the GPUs 3. D graphics engine. In premiere Pro 6, MPE acceleration will greatly affect how quickly Adobe can render video to the exporter. So a more powerful Kepler GPU will probalby complete projects faster than a less powerful one up to NVENCs performance ceiling. For more info, please refer to NVidias NVENC whitepaper at their developer website public6 I have a multi GPU setup, can I encode with multiple GPUs No, NVENC targets and uses only a single physical GPU. You can choose which one. Known limitations and problems NVENC plugin is a proof of concept program it is not a finished product. So its missing some features, and other things are known to be broken Interlaced video encdoing does not work at all not supported in current consumer Geforce driversAudio support is very limited uncompressed PCMno AAC or Dolby Digital. Multiplexer support is very limited MPEG 2 TS only, using an included third party tool TSMuxer. EXEno MPEG 4 muxing. MP4When the muxed MPEG 2 TS file in Windows Media Player WMP, there is no sound. This is because WMP doesnt recognize PCM audio in mpeg 2 ts files. You have 2 choices you can use a third party media player such as MPC HC or VLC. Or you can postprocess the audio WAV file into a compatible format Dolby DigitalAC 3in the pop up plugin User interface, the lt multiplexer tab is missing or not shown properly. To fix Select a different codec, then re select NVENCexport. Doesnt support older NVidia GPUs GTX5xx and older, GT6. Sorry, NVENC hardware was introduced with NVidias Kepler family 2. Anything older than that will NOT work with the plugin.
