Jul 8, 2010 · If you use GTX 950 series or higher graphics cards (Maxwell, GM20x), you will be able to use the Nvidia NVENC HEVC(H. However I have not tried AMF as I don't have an APU. AMD has improved their encoding but AMF is still behind Nvenc for streaming quality and Quicksync for offline encodes. e. 264 video, lossless FLAC stereo audio, and Dolby Digital (AC-3) 5. 264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (decoders: h264 h264_v4l2m2m h264_qsv ) (encoders: libx264 libx264rgb h264_omx h264_qsv h264_v4l2m2m h264_vaapi ), and the transcoding process shows: [hevc @ 0x561e69691a00] Using auto hwaccel type vaapi with new default device. mp4 -c:v h264_nvenc -cq 21 -c:a copy output. Aug 24, 2016 · Anyways, I was just wondering what each of the Nvenc Encoders do. 5) between x265 and NvEnc, you need to go from 4. AMD AMF. Aug 17, 2019 · h264_nvenc uses the NVidia hardware assisted H. 264's High profile performs so much better than Main or Baseline. But at 6 and 8 Mbps Turing AVC/H. 12. 264 Jun 6, 2020 · After far too many requests to updated my previous X264 vs NVENC and NVENC vs AMF/VCE videos with newer AMD drivers, I've finally put together what I consider to be the ultimate package of encoder quality comparisons. Edit: Fixed a character. The real question becomes which bitrate and that is highly dependent on the content and your preference. NVENC, then QuickSync, then x264. 264 encoder. So there is no way of comparing as X264 and X265 are cpu encoding NVENC and AMD-VCE gpu encoding. Encoder Usage (from 0 to 5) (default transcoding) Jan 14, 2022 · How exactly does VAAPI work? Does it just use the the way that NVENC or h264_amf and hevc_amf works? Would it be possible to use the main GPU cores on either Nvidia or AMD cards? From what I found from looking up the h264_vaapi and hevc_vaapi encoders, they're just the linux equivalents of h264_amf and hevc_amf, right?. h264 -loglevel verbose. For instance, 'preset' - should i aim high quality / high performance / other. HEVC has a ~15-50% efficiency benefit over h. AV1 is like 30% faster (I'm monitoring the Video encoder load and power usage and playing at 4k 120fps) and thus you can use a slower profile and get much better quality vs HEVC. If you're building a new setup and don't need AV1 (eg, Twitch streamers since they're still stuck on h. NVENC.
