(4) What's the maximum-size video NVENC-export can handle? 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. The NVENC hardware block has very little CPU-overhead. 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 A/Vbitstreams - this is still done in software (on the host-CPU) From here, NVENC hardware takes over, and handles all aspects of the video compression. The plugin fetches videoFrames from the Adobe application, then converts the frames from YUV420 to NV12 surface-format (using host-CPU.) Then it passes the converted frames to the NVENC front-end. (3) How does NVENC-export encode the video? At medium-high bitrates, NVENC is comparable to Mainconcept. On a dual-socket Xeon Ivy Bridge-E system, NVENC would probably only be 2x faster (in Media Encoder.)Ĭomparing similar settings/video-bitrate, Mainconcept performs better at lower-bitrates(less artifacts). On my test-system, which is ordinary desktop PC with Intel i5-3570K (4-core 3.4GHz), NVENC-plugin is roughly 4x faster than Mainconcept.

Usually, this is C:/Program Files/Adobe/Adobe Premiere Pro CS6 (1) On your system, locate the installation-directory for Premiere Pro CS6. (2) Microsoft Visual C++ 2010 SP1 圆4 redistributables Note,if you have MPE-acceleration enabled, keep in mind the NVENC-plugin consumes some additional VRAM because it uses your GPU to perform H264-encoding. (Sorry, NVidia Fermi is NOT supported, it doesn't have the NVENC hardware feature) (1)NVidia KeplerGPU with 1GB VRAM or more (GTX650 or above, GT650M or above) (NVidia NVENC SDK doesn't support MacOSX.) (1)Adobe Premiere Pro CS6 or Media Encoder CS6 (Windows version) It comes with no warranty - use at your own risk. !!!! Disclaimer: NVENC-export is third-party software that is not supported by either Adobe or NVidia. This software is "proof-of-concept", so it's missing some critical features (no interlaced-video support, no AAC-audio or Dolby AC-3 audio), and of course, it could be buggy! But it's free. It requires an NVidia 6xx/7xx series "Kepler" GPU (CUDA capability 3.0), and uses the dedicated GPU's builtin hardware-encoder (NVENC) to offload the H264-encoding process from the host-CPU. I have written a 'proof-of-concept' GPU-accelerated H264-encoder for Adobe Media Encoder (CS6).
