Converting KML Files to Video: A Step-by-Step Guide

4.3 QGIS + Time Manager + FFmpeg (Desktop, Open Source)

  1. Load KML into QGIS (convert to GeoPackage or shapefile first).
  2. Use Time Manager plugin to control temporal visibility.
  3. Create a Print Layout with fixed map extent, or use QGIS2Web to export to Leaflet/Cesium.
  4. Use qgis_process command-line to export map canvas images iteratively.
  5. Encode with FFmpeg.
  • Set map canvas size to desired video resolution (Project → Project Properties → General → Map Units/Canvas size or use Layout Manager).

    • Converting a KML (Keyhole Markup Language) file to a video is not a direct file-format conversion because KML contains spatial data (points, lines, and polygons), while video is a sequence of images. To create a video, you must the KML data within a mapping environment. 1. Google Earth Pro (Best for Quick Flyovers) Google Earth Pro

    1. Parse the KML to extract geometric data (e.g., a route’s coordinates).
    2. Render that data onto a map background.
    3. Animate the viewpoint or data appearance over time.
    4. Encode the frames into a video.

    Have you ever looked at a flat KML path in Google Maps and thought, "This would look amazing as a 3D flyover"? Whether you’re a travel vlogger showing off a recent trek or a developer visualizing logistics routes, turning raw geographic data into video is a game-changer.

    Recording a Tour: Import your KML file into Google Earth Pro. You can record a "tour" by navigating through your placemarks or paths manually or by right-clicking a folder of KML points and selecting "Play Tour".
