Subtitle Options

Introduction

FFEncoder can copy subtitle streams from the input file to the output file using the -Subtitles / s parameter. I have not added subtitle transcoding because, frankly, ffmpeg is not the best option for this. If you need to convert subtitles from one format to the other, I recommend using Subtitle Edit (Windows only).

Parameter Options

The different parameter options are:

• default / d - Copies the default (primary) subtitle stream from the input file
• all / a / copyall / ca - Copies all subtitle streams from the input file
• none / n - Excludes subtitles from the output entirely

By Language

You can also specify a language to copy, and FFEncoder will search the input for all subtitles matching that language. If the specified language isn't found, no subtitles will be copied. The following languages are supported using the corresponding ISO 639-2 code on the right:

Language	ISO 639-2 Code
Arabic	ara
Bulgarian	bul
Chinese	chi / zho
Czech	cze
Danish	dan
Dutch	dut / nld
English	eng
Estonian	est
Finnish	fin
French	fre
German	ger
Greek	gre / ell
Hebrew	heb
Hindi	hin
Indonesian	ind
Korean	kor
Polish	pol
Portuguese	por
Romanian	rum
Russian	rus
Slovenian	slv
Spanish	spa
Swedish	swe
Turkish	tur
Vietnamese	vie

Language Negation

Additionally, you can use the ! character with a language code to copy everything but that language. For example:

# Copy all subtitles except English
PS > .\FFEncoder.ps1 'in.mkv' -CRF 17 -Subtitles '!eng' -o 'out.mkv'
