# 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
- Noto Sans Bold for the bottom-left/bottom-right stamps
- IBM Plex Sans SemiBold for per-file captions

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'
sudo apt install fonts-noto-core fonts-ibm-plex
fc-cache -f
```

Check that fonts are available:

```bash
fc-match 'Bebas Neue'
fc-match 'Noto Sans'
fc-match 'IBM Plex Sans'
```

## Optional Jamendo music download

If the input folder has no audio file, movmaker can download one random track from Jamendo.

Save your Jamendo client ID in either an environment variable:

```bash
export JAMENDO_CLIENT_ID='your_client_id_here'
```

or in a local config file:

```bash
mkdir -p ~/.config/movmaker
echo 'JAMENDO_CLIENT_ID=your_client_id_here' > ~/.config/movmaker/jamendo.env
chmod 600 ~/.config/movmaker/jamendo.env
```

The default music search query is:

```text
cinematic punk rock
```

Override it with:

```bash
python3 movmaker.py input --music-genre "upbeat rock"
```

## 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, but if present every non-empty, non-comment line must use mandatory `key: value` syntax. Plain positional lines are not supported.

Movie metadata keys:

```text
Title: Paris Trip
Location: Paris, France
Date: May 2024
Description: Longer description shown in MVLog and embedded in final MP4 metadata.
```

Supported metadata key aliases:

- title: `Title` or `Name`
- location: `Location`, `Place`, or `Where`
- date: `Date`, `Dates`, or `When`
- description: `Description`, `Desc`, or `Synopsis`

If the date entry is omitted, movmaker uses the date from the first picture/video and displays it like:

```text
May 2026
```

If the location entry is omitted and GPS coordinates are found in the first picture/video that has them, movmaker reverse geocodes them and uses that as the location. It tries to return only `city/town/village, country`; if no city/town/village is found, it uses just the country.

Any other `key: value` line is treated as a per-file caption where the key is the exact media filename:

```text
IMG_001.jpg: Eiffel Tower
IMG_002.jpg: Louvre
IMG_003.jpg: First line | Second line
```

## MVLog worker

`mvlog_worker.py` can be run from this machine by cron or a systemd timer to process MVLog jobs stored on the web machine.

Default paths:

- remote host: `192.168.0.204`
- remote web root: `/var/www/html/mvlog`
- inputs: `in-dir/<job>/`
- outputs: `out-dir/YYYYMMDD_title.mp4`
- per-job state: `in-dir/<job>/.movmaker-state.json`

The worker:

1. scans remote `in-dir/`
2. computes a fingerprint from input filenames, sizes, and mtimes
3. skips jobs whose fingerprint matches a completed state file and whose output exists
4. copies changed jobs locally
5. renders with `movmaker.py`
6. uploads the MP4 atomically to remote `out-dir/`
7. removes the old output if the regenerated filename changed
8. clears the web metadata cache

Run once:

```bash
./mvlog_worker.py
```

Process one job:

```bash
./mvlog_worker.py --job romo2026
```

Force regeneration:

```bash
./mvlog_worker.py --job romo2026 --force
```

Pass extra movmaker options:

```bash
./mvlog_worker.py --movmaker-arg=--preview
```

Recommended scheduling is a systemd timer or cron with a separate lock, e.g. every `MVLOG_WORKER_RECOMMENDED_INTERVAL_MINUTES` minutes (5 minutes; see `mvlog_worker.py`).

## Usage

Basic:

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

With options:

```bash
python3 movmaker.py input \
  --out-dir . \
  --image-duration 6 \
  --fade 3 \
  --audio-fade 10 \
  --audio-fade-in 2 \
  --video-fade 1.5 \
  --music-genre "cinematic punk rock" \
  --resolution 1920x1080 \
  --fps 30
```

Fast preview render:

```bash
python3 movmaker.py input --preview
```

## Configuration knobs

The most common visual timing/styling tweaks are exposed as constants near the top of `movmaker.py`:

| Constant | Purpose | Default |
| --- | --- | --- |
| `INTRO_LOGO_TARGET_HEIGHT_RATIO` | Portion of the video height used for the intro logo before padding (e.g. `0.75` = 75 % of frame height). | `0.75` |
| `INTRO_LOGO_EXTRA_HOLD` | Extra seconds the synthesized intro still remains before the first crossfade. | `6.0` |
| `INTRO_LOGO_FADE_OFFSET` | Minimum time (s) the logo stays fully visible before the first xfade is allowed to start. | `3.0` |
| `INTRO_TITLE_FADE_DELAY` | Seconds after start before the main title begins fading in. | `2.0` |
| `INTRO_TITLE_FADE_LENGTH` | Seconds the fade-in/out lasts. | `1.0` |
| `INTRO_TITLE_VISIBLE` | Seconds the title stays fully visible between fade in/out. | `4.0` |
| `DEFAULT_IMAGE_DURATION` | Default fully visible time per still image before fades are added. | `6.0` |
| `DEFAULT_CROSSFADE_DURATION` | Default crossfade duration between media items. | `3.0` |
| `FIRST_IMAGE_DURATION_MULTIPLIER` | Multiplier applied to the first still’s `--image-duration` to delay the first transition. | `2.0` |
| `DEFAULT_AUDIO_FADE_IN` | Default audio fade-in duration. | `2.0` |
| `DEFAULT_AUDIO_FADE_OUT` | Default audio fade-out duration. | `10.0` |
| `DEFAULT_VIDEO_FADE` | Default video fade-in/out duration for the first/last real clips. | `1.0` |
| `INTRO_VIDEO_FADE_ENABLED` | Whether the synthesized intro/logo pad gets the global fade-in effect (`False` keeps it fully visible from frame 0). | `False` |

Adjust these constants and rerun `movmaker.py` to change the intro behavior without touching the rest of the pipeline.

## Current behavior

- scans one flat input directory
- supports an optional intro logo overlay via `--intro-logo`
- supports AJAX save for input-dir create, edit, delete with toast notifications and redirect cleanup
- auto-detects media/audio/data files by extension
- shows each image fully visible for `DEFAULT_IMAGE_DURATION` seconds by default (6 s), not counting crossfades
- keeps the first image longer so the first transition starts after `FIRST_IMAGE_DURATION_MULTIPLIER * DEFAULT_IMAGE_DURATION` seconds (12 s with defaults)
- includes video clips inline
- crossfades between media items over `DEFAULT_CROSSFADE_DURATION` seconds by default (3 s)
- loops/trims music to match the video
- if no audio file exists in the input folder, searches Jamendo using `--music-genre` and downloads one random Creative Commons track that allows non-commercial reuse and derivative works; default query is `cinematic punk rock`
- reads the Jamendo client ID from `JAMENDO_CLIENT_ID` or `~/.config/movmaker/jamendo.env`
- fades music in over `DEFAULT_AUDIO_FADE_IN` seconds (2 s) and out over `DEFAULT_AUDIO_FADE_OUT` seconds (10 s) by default
- builds a black intro still (matching the first media item’s resolution) when `--intro-logo` is provided, scales the logo to `INTRO_LOGO_TARGET_HEIGHT_RATIO` of the frame height (75 % by default), shows it at full opacity from frame 0, and keeps it on screen for `audio_fade_in + INTRO_LOGO_EXTRA_HOLD` seconds (with defaults this is `DEFAULT_AUDIO_FADE_IN + INTRO_LOGO_EXTRA_HOLD`, i.e. 8 s) before allowing the first crossfade
- opening title text fades in after `INTRO_TITLE_FADE_DELAY` seconds (2 s), stays visible for `INTRO_TITLE_VISIBLE` seconds (4 s), then fades out over `INTRO_TITLE_FADE_LENGTH` seconds (1 s)
- fades the first real clip in and the final clip out with the `--video-fade` duration (default `DEFAULT_VIDEO_FADE`, currently 1 s); the black intro/logo pad respects this fade-in only when `INTRO_VIDEO_FADE_ENABLED` is `True`
- displays optional per-file captions at bottom center with slightly off-white text and a soft shadow; use `|` to split caption lines
- adds persistent bottom-left title/date/place and bottom-right `Bubulescu.Org` stamps
- preserves special characters in rendered overlays and metadata
- uses safe ASCII only for generated filenames, so special letters become readable equivalents like `Č` -> `C`, `å` -> `a`, `ø` -> `o`
- embeds MP4 metadata: title, date, location/place, QuickTime location name, artist, comment, and creation_time
- writes an MP4 file named like `YYYYMMDD_title.mp4` in the current directory by default; use `--out-dir DIR` to choose another output directory
- takes `YYYYMMDD` from the first picture/video metadata, falling back to file modification date
- keeps console output minimal during rendering and writes detailed ffmpeg output to timestamped logs in `.logs/` inside the input directory
- 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.
