MSP15 build 116 encoding times: MSP15 MagixAVC/AAC MP4 Internet HD1080 NVEC (CBR and high performance) - 59 seconds The NVENC options are matched as best I understand them between the presets available with ffmpeg/nvenc. ffmpeg with NVENC h/w enc using system ram, ~ 32 seconds.ffmpeg with NVENC full h/w dec/enc, ~ 7 (SEVEN) seconds (best case).ffmpeg command for reference # full h/w decode/encode using gfx card memory - remove "-hwaccel cuvid" to disableįfmpeg -y -hwaccel cuvid -c:v h264_cuvid -i gopro.mp4 -vf scale_npp=-1:1080 -c:a copy -c:v h264_nvenc /export/public/foo.mp4įWIW, downsizing 2.7k mp4 to 1080 mp4 GoPro 2.7K 23.976fps, 328MB, 1min When I force ffmpeg to h/w decode/encode but with system memory, it takes a little over 2mins 30seconds (still better than MSP) and CPU only takes closer to 10mins. and ffmpeg it took 31 SECONDS !!! Yes MSP15 vs ffmpeg/linux is not direct comparison and the encoding options are not exactly the same but, COME ON, the new NVEC Movie Studio is clearly not working as expected.įfmpeg was using full h/w transcode, using the GPU memory and not system memory. I downsize the same GoPro file from the same harddisk and write the output to the same output disk as used by MSP. To prove that my system is not the bottleneck, I dual boot to linux and run a NVEC enabled ffmpeg. The CPU is at about 70-90% but the GPU (through GPUz) is only 13-16% utilisedĪs a programmer in my former life it is very clear to me the GPU is not being used correctly. I run this through MSP15 MagixAVC/AAC MP4 Internet HD1080 NVEC (CBR and high performance) and MSP15 took 6 MINUTES. My system is old, an 8x core i7 870 12GB RAM Win7圆4 machine, but the GPU is a GTX1060 3GB card.įor a simple comparison to demonstrate a point, I took a 6min 23sec GoPro file that is 2.7k 24fps and I want to downsize to 1080, no edits added to timeline. So I want to know if we've been sold snake oil or it's user or error "work in progress"!!! However from my current experience, version 15 barely improves on GPU encoding. One of the reasons I upgrade from MSP13 to 15 was because of claims of hardware accelerated NVENC and the positive links like this:
