# movmaker

Simple Python + ffmpeg movie maker.

Drop pictures, videos, music, and optionally one simple `data.txt` file into a single flat input directory. Then run one command to create an MP4 video.

No YAML. No required subdirectories.

## Requirements

- Python 3
- `ffmpeg`
- `ffprobe` usually included with ffmpeg

Install on Debian/Ubuntu/Raspberry Pi OS:

```bash
sudo apt install ffmpeg
```

## Fonts

The default title/stamp styling uses these fonts:

- Bebas Neue for the opening title, date, and location
- Inter for the bottom-left and bottom-right stamps

Both fonts support common Danish and Croatian characters such as `æ ø å Æ Ø Å č ć ž š đ Č Ć Ž Š Đ`.

Install them locally for the current user:

```bash
mkdir -p ~/.local/share/fonts/google
curl -L -o ~/.local/share/fonts/google/BebasNeue-Regular.ttf \
  'https://github.com/google/fonts/raw/main/ofl/bebasneue/BebasNeue-Regular.ttf'
curl -L -o ~/.local/share/fonts/google/Inter%5Bopsz,wght%5D.ttf \
  'https://github.com/google/fonts/raw/main/ofl/inter/Inter%5Bopsz,wght%5D.ttf'
fc-cache -f ~/.local/share/fonts/google
```

Check that fonts are available:

```bash
fc-match 'Bebas Neue'
fc-match 'Inter'
```

## Input folder

Example:

```text
input/
  IMG_001.jpg
  IMG_002.png
  holiday_clip.mp4
  music.mp3
  data.txt
```

Supported file types:

- Images: `.jpg`, `.jpeg`, `.png`, `.webp`, `.bmp`, `.tif`, `.tiff`
- Videos: `.mp4`, `.mov`, `.mkv`, `.avi`, `.webm`, `.m4v`
- Audio: `.mp3`, `.wav`, `.m4a`, `.aac`, `.flac`, `.ogg`
- Data: `data.txt`, `info.txt`, or `title.txt`

Files are ordered by filename, so names like this work well:

```text
001.jpg
002.jpg
003.mp4
004.jpg
```

## data.txt

`data.txt` is optional.

Simplest format:

```text
Paris Trip
May 2024
Paris, France
```

Those three lines mean:

1. title
2. date
3. place

Key/value format also works:

```text
title: Paris Trip
date: May 2024
place: Paris, France
```

Optional per-file captions may be supported, but they are not required:

```text
IMG_001.jpg: Eiffel Tower
IMG_002.jpg: Louvre
```

## Usage

Basic:

```bash
python3 movmaker.py input
```

With options:

```bash
python3 movmaker.py input \
  --out-dir out \
  --image-duration 6 \
  --fade 3 \
  --audio-fade 10 \
  --first-transition-at 12 \
  --resolution 1920x1080 \
  --fps 30
```

## Current behavior

- scans one flat input directory
- auto-detects media/audio/data files by extension
- shows each image fully visible for 6 seconds by default, not counting crossfades
- keeps the first image longer so the first transition starts at 12 seconds by default
- includes video clips inline
- crossfades between media items over 3 seconds by default
- loops/trims music to match the video
- fades music in at the beginning and out at the end over 10 seconds by default
- overlays the opening title for the first 6 seconds: large bold title, then smaller non-bold date/location on one line
- adds persistent bottom-left title/date/place and bottom-right `marijo@novosel.dk` stamps
- writes an MP4 file named like `YYYYMMDD_title.mp4` by default
- takes `YYYYMMDD` from the first picture/video metadata, falling back to file modification date
- uses local `ffmpeg/ffmpeg` and `ffmpeg/ffprobe` when present, otherwise system tools

## Notes

This is an early version. The intended workflow is deliberately simple: dump files into one folder and run the script.
