Requirements

Item	Details
QGIS	4.x (Qt6). QGIS 3 is not supported.
Video	MISB/STANAG 4609 with KLV, or create one via multiplexer
FFmpeg	Required — paths in FMV Settings
Python	`opencv-contrib-python`, `matplotlib`, `pymisb` — see `code/requirements.txt`
DEM	Optional GeoTIFF/HGT for terrain intersection

Tip: Use the FMV Settings button (gear on toolbar) instead of editing settings.ini.

Playback uses OpenCV (no GStreamer / LAV Filters). Live streams supported: UDP, TCP, RTP, RTSP via File → Open Stream.

Developers: run ./install_dev.sh (macOS) or install_dev.bat (Windows) to symlink the plugin and install runtime packages into QGIS bundled Python.

FMV Settings

Toolbar → FMV Settings (or Plugins → Full Motion Video → FMV Settings)

Configure in one place:

FFmpeg / ffprobe folder
DEM (optional elevation model)
Reverse geocoding URL
Layer names used when creating video groups
Mosaic live mosaic tuning (interval, feather, max size)
AI Detection — YOLO/ONNX models, VisDrone download, confidence, class IDs
Dependency check — pymisb, OpenCV, FFmpeg status
Install dependencies — guided setup when available

Changes are saved to code/settings.ini (plugin root) and applied without restarting QGIS.

AI Detection tab

FMV Settings → AI Detection

Control	Purpose
Use YOLO/ONNX	Enable OpenCV DNN for supported filters
Model profile	aerial (VisDrone, FMV/UAV) · coco (ground-level) · custom
Download VisDrone	One-click YOLOv8n download + ONNX export to `~/.qgis-fmv-models/`
ONNX path	Override model file (absolute path)
Confidence / NMS	Detection thresholds (try 0.15 confidence for small aerial objects)
Per-filter class IDs	Comma-separated YOLO class indices per filter
Per-filter ONNX	Optional separate `.onnx` per filter (building, road, fire, …)

VisDrone class IDs (default for aerial):

Vehicle: 3,4,5,8,9 (car, truck, bus, van, …)
Person: 0,1 (pedestrian, people)

Building, road, fire, smoke and flood use smart CV unless you assign a custom ONNX and class IDs.

Playback

Control	Action
Play / Pause	`Ctrl+P`
Stop	`Ctrl+S`
Seek	`←` `→` or slider
Loop	`Ctrl+L`
Record clip	`Ctrl+R`
Volume / mute	`Ctrl+U`

Video decodes with OpenCV; audio export uses FFmpeg.

Metadata dock

Ctrl+T — MISB tags for the current frame. Export CSV or PDF.

Video menu

Item	Description
Filters	Real-time enhancement, indices, motion — plus AI Detection submenu
Frames	Capture current / all / georeferenced
Video info	ffprobe JSON tree
Bitrate	Audio/video bitrate plots
Mosaic	Live georeferenced mosaic (`Ctrl+M` toolbar button)
Converter	Remux to another container

Map & layers

Each video gets a layer group with symbology driven by telemetry:

Layer	Content
Platform	Sensor position + heading (pick icon in Options → Platform)
Footprint	Ground footprint polygon
Beams	Sensor corner rays
Trajectory	Platform path (decimated for performance)
Frame Center / Axis	Target geometry
Drawings	User sketches on video
Military Symbols	APP-6D inspired symbols placed on video/map
Sensor Coverage Cone / Distance Rings	Optional C2 overlays from FMV Tools

Center modes

Video → Center on Platform / Footprint / Target — re-centers the QGIS map canvas on the active feature.

Platform icon

Options → Platform tab — thumbnail picker from military, DJI, UAV, helicopter, ship, tank presets. Updates the map layer immediately.

Video Filters

Access via Filters menu in the player. All filters work in real-time during playback.

Image enhancement

Filter	Description
CLAHE	Adaptive histogram equalization — improves contrast in shadows, fog, dark video
Sharpen	Unsharp mask — makes buildings, vehicles, roads more visible
Brightness / Contrast	Manual adjustment with slider dialog
Auto Contrast	Automatic CLAHE-based contrast
Dehaze	CLAHE + contrast stretch for foggy or low-visibility images
Road Enhancement	CLAHE + Sobel + Sharpen combined — highlights roads and structures

Edge detection

Filter	Description
Canny Edge	Classic Canny edge detection
Sobel	Sobel gradient magnitude — highlights structural edges, buildings, lines

Color & vegetation

Filter	Description
False Color (Turbo)	Rainbow LUT — makes intensity differences easy to interpret
Vegetation Index (ExG/VARI)	Excess Green index — NDVI equivalent for RGB cameras without NIR

Detection & motion

Filter	Description
Motion Detection	Frame difference — highlights moving objects with minimal cost
Background Subtraction (MOG2)	Adaptive background model — automatically detects moving objects
Hotspot Detection	Highlights brightest pixels (thermal cameras) in red overlay

AI Detection (summary)

Segmentation filters for buildings, roads, vehicles, persons, fire, smoke and flood live under Filters → AI Detection. See AI Detection for YOLO setup, VisDrone, and [FILTERS] tuning.

Quick filters

Filter	Description
Gray Scale	Convert to grayscale
Invert Colors	Invert pixel values
Mono	1-bit monochrome
Mirror Horizontal	Flip video horizontally

Note: Only one "slow" filter can be active at a time (CLAHE, Sharpen, Sobel, AI Detection, etc.). Quick filters (Gray, Invert, Mono, Mirror) can combine with any slow filter.

AI Detection

Designed for FMV and UAV aerial video. Open Filters → AI Detection in the player.

Available filters

Menu item	Primary engine	Fallback
Vehicle (YOLO AI)	VisDrone YOLOv8n (ONNX)	Smart CV (blob + edge + motion)
Person (YOLO AI)	VisDrone YOLOv8n (ONNX)	Smart CV (vertical shape)
Building (CV + AI)	Smart CV	Optional custom YOLO ONNX
Road (CV + AI)	Smart CV + lane hints	Optional custom YOLO ONNX
Fire (CV + AI)	HSV warm-color CV	Optional custom YOLO ONNX
Smoke (CV + AI)	Low-saturation texture CV	Optional custom YOLO ONNX
Flood (CV + AI)	Blue/cyan water band CV	Optional custom YOLO ONNX

On-screen overlay

Each AI filter draws:

Colored tint on high-confidence regions (adaptive thresholds for aerial video)
Bounding boxes with optional #track_id and confidence % on each box
Status banner at the top, e.g. VEHICLE [YOLO] det:3 12% or BUILDING [CV] det:2 8%

[YOLO] = OpenCV DNN; [CV] = classical computer vision; [SCIPY] / [NUMPY] = fallback without OpenCV.

Setup (first time)

FMV Settings → AI Detection
Click Download VisDrone aerial model (or point ONNX path to your own model)
Enable Use YOLO/ONNX for segmentation filters
Keep profile aerial for FMV/UAV footage
Open a video → Filters → AI Detection → Vehicle (YOLO AI)

If YOLO finds nothing on a frame, the plugin automatically falls back to tuned CV when dnn_fallback_when_empty is enabled (default).

Advanced tuning (`settings.ini`)

Section [DNN] — model path, profile, confidence, NMS, class IDs.

Section [FILTERS] — aerial detection profile (defaults optimized for FMV):

Key	Default	Effect
`profile`	`aerial`	Enables FMV-tuned thresholds
`overlay_abs_threshold`	`0.10`	Lower = more visible tint
`detection_percentile`	`70`	CV sensitivity
`clahe_pregain`	`true`	CLAHE before detection (haze)
`multiscale_detection`	`true`	Fuse full-res + half-res scores
`box_nms_iou`	`0.42`	Remove duplicate CV boxes
`show_box_confidence`	`true`	Labels on boxes
`tracking_enabled`	`true`	Stable `#id` across frames
`dnn_fallback_when_empty`	`true`	YOLO → CV when no DNN hits

Template with comments: code/settings.sample.ini.

Tips for aerial FMV

Use aerial profile, not coco, for drone footage
Lower onnx_confidence to 0.12–0.15 for very small vehicles
Vehicle/Person need VisDrone; other classes need a custom 7-class ONNX if you want true YOLO for fire/smoke/etc.
On macOS, if OpenCV is blocked by code signing, filters still run on numpy/scipy fallbacks (slower, fewer boxes)

FMV Tools

Menu Tools in the player:

Geo-intelligence

These tools turn FMV into a map ↔ video time machine. They need a video with live KLV/MISB telemetry (play a few seconds so the trajectory and footprint appear).

Spatial timeline bookmarks

Play until telemetry is flowing.
Press B (or Tools → Add Timeline Bookmark).
Markers appear on the custom timeline; alerts and the Detection Sentinel also drop red markers automatically.
Tools → Export Timeline Bookmarks… → CSV or KML with lat / lon / alt (frame center).

KML opens in Google Earth / QGIS as real placemarks (not 0,0).

Geofence (spatial AOI)

Play until a Footprint is drawn on the map.
Tools → Set Geofence from Footprint — a red AOI polygon is added to the video group.
When the frame center enters the AOI → alert message + red timeline marker + HUD flash.
Tools → Clear Geofence removes the AOI.

AOI Detection Sentinel

Combine geofence + AI:

Arm a geofence (above).
Keep Tools → Watch Detections in Geofence checked (default ON).
Keep Tools → AI Detections on Map checked.
Enable a filter under Filters → AI Detection (e.g. Vehicle / Person).
When a detection lands inside the AOI → SENTINEL: 2×vehicle inside Footprint Geofence, timeline bookmark, and a red banner on the video.

Click Map to Seek

Play with telemetry so the geo/time index builds.
Map → Click Map to Seek (Ctrl+Shift+J).
Click near the trajectory / flight path → video jumps to that time.

Map Time Machine (wow demo)

“Scrub the mission on the map.”

Play the video with KLV so the plugin records (position, time, footprint) samples.
Map → Map Time Machine (Ctrl+Shift+T).
Move the mouse along the flight path on the QGIS canvas:
- Video seeks live to that moment
- A translucent ghost footprint shows what the sensor was looking at
Click to lock a moment; uncheck the tool to exit.

Mutually exclusive with Click Map to Seek and Lookback.

Lookback — “What did we see here?” (analyst wow)

Reverse query: pick a building, crossroads, or AOI on the map and ask when did the sensor look at this?

Play with KLV so footprints are recorded in the geo/time index.
Map → Lookback — What did we see here? (Ctrl+Shift+L).
Click a point on the map.
A dialog lists every clustered time the footprint contained that point.
Double-click a row (or OK) → video jumps there and the ghost FOV appears.

If no footprints were stored yet, Lookback falls back to times when the platform/frame-center was near the click (within ~80 m) and tells you to play longer for true FOV hits.

Mutually exclusive with Time Machine / Click-to-seek.

Target Pin / Cue (cross-cue wow)

Pin any ground point and treat it as a live cue:

Play with KLV so the geo/time index (and footprints) build.
Map → Pin Target on Map (Ctrl+Shift+N) → click a building / crossroads / AOI.
A yellow cross appears on the map; the video shows a cue chip:
- TGT 1.2 km / 045° / FOV@42.1s (+8.3s) while approaching
- TGT … / IN FOV when the footprint covers the pin
When coverage enters, a TARGET CUE alert fires (bookmark / Instant Replay / Storyboard if enabled).
Map → Jump to Next Target FOV (Ctrl+Shift+U) seeks the next recorded visit.
Map → Clear Target Pin removes the cue.

Mutually exclusive (while arming) with Click-to-seek / Time Machine / Lookback.

AI Detections → Map

Tools → AI Detections on Map must be ON (checkable).
Enable an AI filter (Vehicle, Person, Fire, …).
When the frame is georeferenced, box centers are projected to WGS84 and written to the AI Detections layer (track id, class, score).

Detection Heat Trail

With AI publishing ON, enable Tools → Detection Heat Trail. Points accumulate on the AI Detection Trail layer (timestamped, capped) so you can see where detections occurred over the mission — not only the latest frame.

Instant Replay on Alert

Tools → Instant Replay on Alert (Ctrl+Shift+R). When a telemetry alert, geofence enter, or Detection Sentinel fires, the player rewinds ~3 seconds and pauses (with cooldown) so you can re-watch the moment.

Live Place Labels

Tools → Live Place Labels (Ctrl+Shift+P) + HUD on (Ctrl+H). The frame center is reverse-geocoded (throttled) and shown as PLACE … on the HUD strip.

Auto Storyboard Captures

Tools → Auto Storyboard Captures (Ctrl+Shift+Y). On each bookmark and alert, a georeferenced GeoTIFF is written under <video folder>/storyboard/ (included in the mission package when present).

Cinematic Map Follow

Map → Cinematic Map Follow (Ctrl+Shift+C) while a center-on mode is active. The canvas eases toward the target instead of jumping each telemetry tick.

Mission package

Tools → Export Mission Package… (Ctrl+Shift+E) builds a ZIP with whatever is available:

File	Content
`MANIFEST.txt`	Inventory
`bookmarks.csv` / `.kml`	Timeline markers + coordinates
`geotime_index.csv`	Samples used by seek / Time Machine
`ai_detections.csv`	Last AI points snapshot
`layers.kml`	Telemetry / drawings (best-effort)
`mosaic.tif`	Live mosaic if built
`geofence.csv`	Armed AOI ring
`storyboard/`	Auto GeoTIFF captures (if any)

Ideal for after-action briefings.

Demo script (2 minutes)

1. Open MISB video → play until footprint + trajectory visible
2. Tools → Set Geofence from Footprint
3. Tools → AI Detections on Map + Heat Trail (ON) + Filters → Vehicle
4. Tools → Instant Replay + Storyboard + Place Labels (ON); HUD on
5. Map → Cinematic Follow + Map Time Machine → scrub along the track
6. Map → Pin Target on a building → watch TGT cue / Jump to Next FOV
7. Map → Lookback → click a building → jump through every revisit
8. When a vehicle enters the AOI → Sentinel flash + rewind + storyboard frame
9. Tools → Export Mission Package → open ZIP / KML / storyboard in QGIS

Tool placement hints

When you activate a drawing or measurement tool, a flashing green banner appears on the video telling you how to use it (e.g. "Click here to place a point", "Double-click to finish line"). The hint disappears after a few seconds or when you deactivate the tool.

Options

Right-click the draw toolbar for options: magnifier size, colors, line styles.

Military symbols

Place NATO APP-6D inspired symbols on the georeferenced video and map.

Draw toolbar → Military Symbols (or the toolbar action in the player).

Steps

Open the Military Symbols dialog.
Pick a category (Friendly, Hostile, Neutral, Special) and symbol from the list.
Optionally enter a unit label (e.g. Alpha-1).
A placement hint banner appears on the video.
Click on the video image (not the dialog) at the target location.
Symbol appears on video and in the Military Symbols map layer.

Manage placements

Action	Where
Remove last	Dialog button or draw toolbar dropdown
Remove all	Dialog button or draw toolbar dropdown
Undo last on map	Same as remove last

Symbols require valid georeferencing (GCP / MISB metadata). SVG assets live in code/images/military/.

Troubleshooting

Map stays empty while video plays

Confirm MISB/KLV data stream exists (multiplexed .ts).
Wait until manager shows Ready.
Check layers are visible in the project tree under the video group.

Trajectory connects loop start/end on repeat

Fixed in recent builds — update plugin. Each loop should start a new segment.

Multiplexer fails

Verify FFmpeg path in FMV Settings.
Check telemetry format (CSV columns or DJI .txt / .log).
Ensure output folder is writable.

Missing OpenCV / pymisb

End users: open FMV Settings → Install dependencies or check the dependency status panel.

Developers:

./install_dev.sh                              # macOS — symlink + requirements
bash scripts/install_plugin_requirements.sh   # deps only

Use the same Python as QGIS — do not pip install --user OpenCV on macOS (breaks signed QGIS). The FMV Settings dependency check shows which interpreter is in use.

Black screen on Windows

Install OpenCV via requirements. Set FFmpeg path. Try Video → Converter to remux unusual containers.

Military symbol does not appear on map

Video must be georeferenced (MISB metadata or valid GCP).
Click on the video surface, not the symbol dialog.
Check the Military Symbols layer is visible under the video group.

AI Detection shows `det:0 0%` or `[CV]` only

Open FMV Settings → AI Detection: profile must be aerial for FMV/UAV (not coco).
Click Download VisDrone or set ONNX path to a valid .onnx file and enable Use YOLO/ONNX.
Vehicle/Person use VisDrone; if YOLO returns no boxes, CV fallback runs automatically.
Tune [FILTERS] in settings.ini — lower overlay_abs_threshold or detection_percentile for more sensitivity.
Ensure OpenCV works (FMV Settings dependency panel). Without OpenCV, only numpy/scipy CV runs.

Filters don't show visible change

Ensure OpenCV is installed (pip install opencv-contrib-python).
Some filters (Motion Detection, Background Subtraction) need video playback to show results.
Check the Filters menu — only one "slow" filter can be active at a time.
