This speed is achieved with a Quadro P4000 from NVidia when encoding 1920×1080 movies with -preset slow. With ffmpeg and a decent GPU (like a Quadro P4000) the h265/HEVC encoder finaly gets a good speedboost with up to 90fps when encoding HD movies with the below parameter values and 200fps when using the GPU accelerated h264 encoder. Left: ffmpeg -crf / Right: Premiere Adobe Media Encoder CBR Booth are encoded with 6 Mbit average bitrate – fot the ffmpeg version, the -crf option was used and for the AME version, the CBR option was used to encode. Using the preset option delivers quality that easyily surpasses Adobe Media Encoder, especially colorbanding and macroblocks artifacts reduced significantly with ffmpeg when using the h264 codec with the -crf option.Ĭompression comparison: 700x400px 1:1 crop from a 1920×1080 sequence.

The commandline tool ffmpeg offers great flexibility when it comes to video and audio encoding with a great advantage: it’s free of use. I would define high quality as equal or near same quality as the original and this is the goal.

High quality is always not easy to define. CUDA GPU Accelerated h264/h265/HEVC Video Encoding with ffmpeg High Quality FFMPEG Video Encoding
