ViralOverlay™

Add styled, timed text to videos 'n GIFs! Kinda like this:

Usage

vo [OPTIONS] FILEPATH OVERLAY_DATA

OVERLAY_DATA: a JSON file path OR a JSON-formatted string containing an
array of overlays, each containing key-value pairs of at least "text",
"start", and "stop". optional keys: "font_size", "font_color",
"text_position_x", and "text_position_y"

Options:
  -g, --gif             output to GIF instead of MP4
  -f, --font-path TEXT  path to the font you'd like to use.
  --help                Show this message and exit.

Example

$ vo <path_to_video> <json_transcript_filepath_or_string> [--gif --font]

(lots of ffmpeg output...)
Okay, I overlaid your text on <path_to_video_overlaid>.

JSON Transcript Format

The json_transcript string or file should look like this:

[
    {
        "start": 1.03,
        "stop": 1.21,
        "text": "I"
    },
    {
        "start": 1.21,
        "stop": 1.44,
        "text": "am"
    },
    {
        "start": 1.45,
        "stop": 1.84,
        "text": "saying"
    },
    {
        "start": 1.85,
        "stop": 2.25,
        "text": "some"
    },
    {
        "start": 2.25,
        "stop": 2.97,
        "text": "words"
    }
]

See sibling projects Transcribe all the Things and tpro for easy, automatic generation of such transcripts.
