Version 17.10 is now available for DOWNLOAD!
After upgrading FFmpeg to v3.2 in the previous release, we discovered a performance regression because multi-threaded was not working. That is fixed now.
One thing that came with the FFmpeg upgrade is NVENC, which is NVIDIA’s hardware-based H.264 and HEVC encoding for Linux and Windows. The quality is not as good as x264 and x265, but it might be faster for previewing an export or capture or just to play around with. To use it, you must have a NVIDIA GPU that supports it. You must choose “h264_nvenc” or “hevc_enc” from the Export > Video > Codec drop-down list - NOT the Format list. There are not presets provided. You can use the Export defaults or one of the H.264 or HEVC presets and change the codec. Just because it is listed does not mean it will work. The codec is listed without doing any capability test. If you right-click the Export job and choose View Log, then it may show some errors if it is not working. HEVC does not support B frames on most (all?) current devices and drivers. This version of Shotcut makes the Export > Codec rate control fields supply the correct options for NVENC.
