I did not use HE-AAC or HE-AACv2 (the latter supports only stereo) because they do not support a variable bitrate quality of 5 for as many sample rates as LC-AAC and the further file size reduction would be miniscule. The user nu774 of the hydrogenaudio forum tested which parameters allow what set of VBR quality parameters. Just if someone has the same problem like me that a smart beamer device not read 10-bit (only 8-bit): add -vf formatyuv420 to the solution from PinggerShikkoken to convert from 10-bit H.265 to 8-bit H. After launching the command window icon in the directory, you must type in the command given below. 264 video file in the same directory of FFmpeg executables. c copy sets stream copy mode for all selected streams. To begin with, you'll need to download the FFmepeg's required executables that will empower you to convert the H264 to H265. map 0 selects all streams from input file x265.mkv. Assuming you want all video, audio, and subtitle streams use: ffmpeg -ss 00:03:00 -i 'input file x265.mkv' -t 00:00:50 -map 0 -c copy -c:v libx264 -crf 18 'output file x264.mkv'.
There will be a warning claiming “Note, the VBR setting is unsupported and only works with some parameter combinations”. You only told it to copy audio and subtitles. I chose the highest variable bitrate setting available ( -vbr 5), which came out to be about 100 kbit/s at stereo audio. I use the following script, which stores converted file in the folder above the one you are currently in:įfmpeg -i "$i" -c:v libx265 -crf 24 -preset veryslow -c:a copy "./$.AAC.mkv" Convert a movie file to x265 with ffmpeg built into UbuntuĪpt-get -y install ffmpeg is enough on Ubuntu 18.04 to convert a video to h.265.
