Timelapse
This repository, beginning with v2.4.0.1, contains the source code for Timelapse. Timelapse is created and maintained by Saul Greenberg of Greenberg Consulting Inc. and the University of Calgary.
Timelapse is an image analyser for camera traps. It is primarily used by scientists to visually analyze images and encode data as tags from thousands to millions of images and videos. While it is agnostic to its use, ecologists are currently the primary users. See the Timelapse web site for packaged downloads and installers, various guides (including a QuickStart guide) and videos oriented towards end-users, and many other resources.
Timelapse is currently in use across the world by various biologists / ecologists / scientists and resource managers within broadly varying institutions --- national and regional parks, ecological agencies, fishery departments, conservation societies, university groups, etc. --- for quite different needs (e.g., wildlife monitoring, fisheries usage, resource monitoring and management, social science studies etc). What they have in common is
- they collect extremely large numbers of images from one to very many field cameras
- they are interested in examining and tagging images (i.e., information describing image details)
- they want to create data fields specific to their projects (i.e., highly customizable data)
- they have their own needs and ways for performing analytics on that data.
Timelapse is optimized for those wanting to turn their images into meaningful data. Users can easily export the data for later analysis in another package of their choosing (e.g., R, spreadsheets, etc.)
Timelapse works with image recognition data, where it integrates access to AddaxAI / Megadetector. Timelapse imports the recognition file produced by that software (or other compatible image recognition tool), and displays detected items within bounding boxes. Queries can be run against recognized entities.
Contributing
Bug reports, feature requests, and feedback are most welcome. Let us know! We can't improve the system if we don't hear from you. If you wish to co-develop this project, see below.
History
Timelapse was originally designed for a fisheries biologist who ran many camera traps in Timelapse mode, hence its name. Over time, its interface and functionality has been extended to meet the needs of a broad variety of users who use camera traps in many different ways.
While a few developers have contributed to Timelapse over the years, the overwhelming majority was (and continues to be) done as a solo effort by Saul Greenberg.
This repository begins at Timelapse Version 2.4.0.1. Earlier Timelapse versions can be supplied if needed by contacting Saul Greenberg.

Development environment
My build was created using Visual Studio 2026
- Common Tools -> GitHub Extension for Visual Studio
Clone the repository locally using Visual Studio's Team Explorer, or by using a GIT interface such as SourceTree, or through GitHub's clone or download options
Development is against .NET 10 (net10.0-windows for WPF applications).
Prerequisites
- Build environment
- Visual Studio 2026
- .Net 10 SDK (the .Net 10 desktop runtime works, but generates non-critical build errors as it does not contain System.Private.CoreLib.dll)
- C++ Redistributables (used by TimelapseTemplateEditor and TimelapseViewOnly)
- WiX Toolset v6.0+ (only required if you are building MSI installers)
- These exe's must be downloaded and located in the Timelapse folder (not the root folder)
- FFMPEG - only ffmpeg.exe is required (the built release included other executables)
- Exiftool - Download and unzip the Windows 64-bit build, then move the exiftool(-k).exe and the exiftool_files folder into the Timelapse folder.
