transfer sub and font during 265 encode

[ghazalo]

hi all and happy new year

i am encoding most of my Animation series to 265 high 10 so it reduce the size and almost keep same quality so i hope that i am doing right with the command i'm writing down

the point is that most of them has soft sub and fonts attached and i do the step as follow

in windows

for %i in (*.mkv) do ffmpeg -i %i -pix_fmt yuv420p10le -c:v libx265 -crf 28 -x265-params profile=main10 %~ni.mp4

then i do in mkvmerge the following

for %%a in (*.mp4) do ("C:\Program Files\MKVtoolnix\mkvmerge.exe" -o "muxed\%%~na.mp4" --attachment-name "adobe.ttf" --attachment-mime-type application/x-truetype-font --attach-file "D:\project\adobe.ttf" "%%~na.mp4" --language "0:ara" "%%~na.ass")

it is easy but extracting the sub from the orginal is hard and manual using MKV toolnix extractor
also when i wanted to do the same in Linux i have no idea what to do or in fact the seedbox may not having mkvmerge so if there is one step in ffmpeg in Linux will be great

my command in Linux after logging in SSH as follows

for dir in *.mkv ; do
ffmpeg -i "$dir" -pix_fmt yuv420p10le -c:v libx265 -crf 28 -x265-params profile=main10 "${dir%.mkv}".mp4;
done

can anyone help to transfer the sub and the font in the same step in both Linux and windows (please no hard sub keep soft sub)

thanks to all in advanced and sorry if this subject repeated

Regards

Try add -map 0 to your ffmpeg command line. That will force ffmpeg to retain other streams. You'll probably have add -c:a copy.

thanks but in this case will not encode just remux also doesn't take attachment fonts

or if you show me how to write the command to keep video encoding and copying the other components thanks again

video info below it may help

thanks but in this case will not encode just remux also doesn't take attachment fonts

Wrong.
1. -map 0 will copy the attachments (use .mkv as output file extension/format, not mp4)
2. he said to use -c:a copy. That will copy the audio. So you set:

-map 0 -c:v libx265 -c:a copy -c:s copy

(Map all tracks/attachments etc from input, encode video using x265, copy audio and subtitle without further encoding)


P.S.: Even if you use "-o output.mp4" mkvmerge will still create an mkv file. Mkvmerge will never output mp4 files.

thank you i will try this command and thanks for clarifying the (a) copy

I have too many times mp4 results from the mkvmerge command just it become mkv if i use GUI but as CMD it stays mp4

Mkvmerge will never output mp4 files. You have only created mkv files with the wrong filename extension. (I.e. like renaming document.pdf to document.doc in Windows explorer.) Luckily most players don't care about the correct filename extension.

aha noted thanks so it appear .mp4 but actually it is .mkv and player just take it because supported both

[ghazalo]

just for final shape before i go several hours encoding then something went wrong for the whole folder the command will be this correct or wrong?

for %i in (*.mkv) do ffmpeg -i %i -pix_fmt yuv420p10le -map 0 -c:v libx265 -crf 28 -x265-params profile=main10 -c:a copy -c:s copy -attach D:\zzz\adobe.ttf -metadata:s:3 mimetype=application/x-truetype-font [G]%~ni.mkv

[ghazalo]

the command above worked

thanks all

[sneaker]

-attach D:\zzz\adobe.ttf -metadata:s:3 mimetype=application/x-truetype-font

If fonts are in the source mkv you don't need to manually extract/attach them. ffmpeg will copy them with -map 0.

i just tried it now
