Utility for tagging movie files

About

tagmov is a utility program for tagging movie files with things like progress bar and texts. When given multiple inputs, combines them (stacks horizontally) into one video.

Getting Started

Prerequisites:

Common Lisp implementation (tested with SBCL), Quicklisp, make and ffmpeg are required. ffmpeg must be compiled with support for drawing text. Also, the default font used is IBMPlexMono-Bold.ttf, so that should be installed, or another font should be defined using the font-file option.

Get sources and build by issuing commands:

git clone https://github.com/octaspire/tagmov.git
cd tagmov
make

Usage

Please note that these examples require movie files video01.mp4 and video02.mp4 to be present in the current working directory.

If using a video with different name or different format, please use the correct name in the following commands.

One Input

This adds a red progress bar and three texts to the video:

./tagmov --font-color blue --text '1 3 10 10 Text at (10,100) during 1s-3s'      \
                           --text '2 3 10 60 This text is shown between 2s-3s'   \
         --font-color red  --font-size 40                                        \
                           --text '1 3 10 110 This is in red and different size' \
         --input video01.mp4 --bar red

Two Inputs

This combines the two given videos horizontally and adds two texts into the result. Note how the x-coordinate of the second text is calculated using expression W-200; this puts the text to start 200 pixels from the right side of the video. This way there is no need to calculate the position by adding the widths of the different input videos manually. Note also, that there can be more than two videos.

./tagmov --font-color red -i video01.mp4 -i video02.mp4 \
         --text "1 3 100 100 BEFORE"                    \
         --text "1 3 W-200 100 AFTER"

The font and text size can also be changed. So can the height of the progress bar. Font, size and color settings are in effect as long as they are not changed.

See all available options with command tagmov --help.
