Unattended video transcoder to H265 and ACC codecs, in MKV containers.
This program transcode video files to H265 and AAC in MKV format. Subtitles, if present, are automatically detected and soft subbed into the corresponding output files.
transcode2H265 uses ffmpeg, mkmerge and other system tools to convert the input videos.
As a python script you can just run the transcode2H265.py file, or put a symbolic link in any directory of your PATH (e.g. /usr/local/bin) The script needs ffmpeg and mkvtoolnix to work, so, if it can not find them in your system it will complain and exit.
Probably, but I use this. I like it and it works well for me, if you like it too, enjoy it.
Just do:
transcode2H265.py video_file[s]
It has some options (type transcode2H265 -h or see below), but defaults should work in most cases.
positional arguments:
video Input video file(s).
optional arguments:
-h, --help Show this help message and exit.
-p PRESET, --preset PRESET
X265 preset [default: medium].
-q CRF, --crf CRF CRF value [default: 28]. Determines the output video
quality. Smaller values gives better qualities and
bigger file sizes, bigger values result in less
quality and smaller file sizes. Default value results
in a nice quality/size ratio. CRF values should be in
the range of 1 to 50.
-r, --replace-original-video-file
If set then original video files will be erased after
transcoding. WARNING: deleted files can not be easily
recovered!
-l AVLANG, --avlang AVLANG
Default audio language for MKV files obtained (used
only if the original stream languages fail to be
determined) [default: eng].
-L SLANG, --slang SLANG
Default subtitle language of soft-subbed subtitles
(only used if original subtitle languages fail to be
determined) [default: spa].
-x FILENAME_POSTFIX, --filename-postfix FILENAME_POSTFIX
Postfix to be added to newly created H.265 video files
[default: _h265].
-t THREADS, --threads THREADS
Indicates the number of processor cores the script
will use. 0 indicates to use as many as possible
[default: 0].
-c, --auto-crop Turn on autocrop function. WARNING: Use with caution
as some video files has variable width horizontal (and
vertical) black bars, in those cases you will probably
lose data.
-v, --version Show program's version number and exit.
In English and Spanish, depending of your locale. I just speak these two languages, so, if you like it in other, you can always contribute...
