fftrim - concatenate, trim and compress video files

Description

fftrim processes raw videos from a camcorder by concatenating, trimming and compressing them according to arguments you supply on the command line, or in a CONTROL file.

Synopsis

Processing a single file

fftrim --in 000001.MTS --out output.mp4 --start 15.5 --end 44:13

Handling concatenated sources

fftrim --in "000001.MTS 00002.MTS" --out output.mp4 --start 45:13 -- 2-1:12

The expression 2-1:12 means a position in the concatenated file that includes the full length of the first clip and 1:12 minutes of the second clip. Similarly, 3-65 and 3-1:05 both mean a position of 1:05 into the third clip.

The source files are concatenated into an intermediate file using the name of the first source file appended with .mp4.

Batch mode

fftrim --source-dir raw --target-dir final

CONTROL file format

The CONTROL file is used for batch processing and appears in the same directory as the source video files. It contains multiple lines of the following format:

# source file(s)    output file   start  end
# ---------------   -----------   -----  ----
000001.MTS        : part1.mp4   : 15.5 : 44:13

Arguments are separated by a colon character flanked by whitespace. Commented lines are ignored.

The following line creates part2.mp4 from source files 000001.MTS and 000002.MTS:

000001.MTS 000002.MTS : part2.mp4 :  44:13 : 2-24:55

The extracted video starts 44:13 into the first source file. and ends at 24:55 into the second file.

Help

fftrim [-mnr] [long options...] --in STR input file(s) --out STR output file --start STR start time --end STR end time --profile STR merge ffmpeg options from named file in $HOME/.fftrim --source-dir STR batch mode, source directory --target-dir STR batch mode, destination directory -r --frame-rate specify framerate (with no arg: fallback to source file frame rate) -n simulate: print commands but do not run them -m simulate: print commands omitting file checks --old-concat use old, broken naming style for concat target --help print usage message and exit

Note that --in, --out, --start and --end options are not available with batch mode
