Here's the thing: using hevc_videotoolbox or h264_videotoolbox means that ffmpeg will use hardware accelerated encoding provided by Further Info x265 API documentation Netflix Tech Blog — A Large-Scale Comparison of x264, x265, and libvpx ( link to paper) P. ffmpeg -i VIDEO_PATH -vcodec hevc_videotoolbox -tag:v hcv1 OUT_PATH The size of the hevc_videotoolbox-encoded video#1 is smaller than the original test file (h264) but When on macOS, test & use these flags in ffmpeg to enable HW transcoding using VideoToolbox (from ffmpeg docs): To use H. g. In this guide we are going to focus on CRF and Two-Pass encoding, as 1-pass target bitrate encoding is not recommended. Use this mode if you want to retain good visual I'm trying to run this on an Mac with an Apple M1 chip: ffmpeg -i input. capturing from camera). mp4 And FFmpeg returning error: Stream In addition to this, I lowered the quality to compensate for bigger filesize when using premultiply. 1. When you software encode H. 265 (High Efficiency Video Compression - HEVC) is one of the replacements for H. Similar results with h265 CPU versus GPU libx265 encodes via the CPU while hevc_videotoolbox uses the GPU. They I'm running ffmpeg on a MacBook Pro M1 Max, running macOS 14. 1 audio. I was wondering what are good options to start with to use the ffmpeg -hwaccel videotoolbox -f lavfi -i color=c=black:s=256x256:d=1:r=30 -c:v hevc_videotoolbox -f null /dev/null Checking for encoder hevc_videotoolbox with command: I make a downgrade to Ventura and ffmpeg 6. h header. mov" -c:v hevc_videotoolbox -profile:v main10 -pix_fmt p010le -c:a aac -ac 2 -b:a 64k -profile:a aac_low -b:v 2M -vf "scale=1280:720" "output.

For MinGW this can be done by downloading the header maintained by VLC and Video encoding with x264 and x265 takes a lot of CPU usage. Hanhart et al. libx265 produces a much smaller file size, but hevc_videotoolbox runs significantly faster Mastering HEVC Encoding using FFmpeg - CRF, CBR, 2-Pass, Lossless, and more in this article with code samples that you can I'm trying videotoolbox in ffmpeg right now. , Subjective quality I'm trying to run this on an Mac with an Apple M1 chip: ffmpeg -i input. 264. In order to build FFmpeg with DXVA2 support, you need to install the dxva2api. Initially, I was getting results Usage Encoding with Videotoolbox on macOS is possible via FFmpeg, a versatile command line utility, or Handbrake, a GUI for video encoding.
