ChSrt

Tool to modify SRT files from a command line.

Currently it supports the following features:

• ASS tag cleanup
• HTML tag cleanup
• Time adjustment
• Encoding auto-detection
• Fixing indices

The easiest way to use it is to just let it do all adjustments:

chsrt -ia *.srt

However, if only a subset is desired, here is the full syntax:

chsrt [options] <file>...

• -a, --all: Executes most common fixes (equivalent to -icf)
• -b, --backup: Creates a backup of the original file before editing
• -c, --clean-all: Executes all available cleanup operations
• --clean-ass: Cleans ASS tags
• --clean-html: Cleans HTML tags
• --clean-html-all: Cleans HTML tags (including bold and italic)
• -f, --fix-all: Executes all available fixup operations
• --fix-indices: Fixes subtitle indices
• --fix-order Sorts all subtitles by time
• --fix-overlap: Fixes overlapping subtitles
• -i, --in-place: Edit file in place
• -t, --time-adjust <time-adjust>: Time adjustment in seconds (can be negative) [default: 0]
