Where to get HandBrake The officially supported version.About HandBrake What HandBrake is, does, and does not.Quick start Learn how to make your first video in minutes.Check the console output to see what happens: Using auto hwaccel type dxva2 with new default device. If not then FFmpeg falls back to the software decoder. If a hardware decoder is available it is automatically used. Using the option '-hwaccel auto' before the inputs (-i) tries to use hardware accelerated decoding as well: ffmpeg -hwaccel auto -i mysource. This encodes the input using the h264 encoder of Intel Quick Sync (because of the -c:v option). So make sure that you finetune the encoding using e.g. Pay attention on the output quality: libx264 might have a better quality by default than a hardware accelerated encoder. On macOS you want to use 'h264_videotoolbox': ffmpeg -i mysource -c:v h264_qsv -c:a copy output.mp4 Here on my Windows machine I will choose the 'h264_qsv' (Intel Quick Sync Video acceleration) encoder. if you have no NVIDIA graphics card the h264_nvenc will not work. Note: not all encoders might actually work. h264_qsv H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (Intel Quick Sync Video acceleration) (codec h264) V.D h264_nvenc NVIDIA NVENC H.264 encoder (codec h264) V.D h264_mf H264 via MediaFoundation (codec h264) V.D h264_amf AMD AMF H.264 Encoder (codec h264) V.D libx264rgb libx264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 RGB (codec h264) To get a short description of each encoder you can execute: ffmpeg -encoders This list is dependent to your OS and the enabled encoders during FFmpeg compilation.

Some are software-, some are hardware-encoders. In this this you should find your target codec (h264): ĭEV.LS h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (decoders: h264 h264_qsv h264_cuvid ) (encoders: libx264 libx264rgb h264_amf h264_mf h264_nvenc h264_qsv )

To check this you can simply execute ffmpeg -codecs Encodingįirst of all you need to know, what encoders have been enabled in your FFmpeg version. But the load depends also on other things like bitrate, resolution and CPU/hardware. And after enabling the hardware accelerated decoding it reduced the CPU load from 20% to 4%. If your CPU support for example Intel Quick Sync than you can significantly reduce the CPU load using hardware acceleration (in my test case below it was from 90% using libx264 to 20% using h264_qsv).
