VIAN WebApp Projects

On the home page of VIAN you can find a multitute of already analysed movies. Besides the possibility to query and explore those on the site of VIAN directly, you can also download a project you’re interested in and look at it in the VIAN application itself.


It is important that you are in possession of the exact same movie file - otherwise the project that will be re-built in your VIAN locally will be corrupted.

To inspect a project locally in your VIAN application, select the movie you are interested in and click download.

Importing a downloaded project in the local VIAN application.

After you specified the project file, VIAN asks you for two more specifications:

  • First, VIAN asks you for the project file - a .json file - you want to import (of course, this is the file you downloaded from

  • In a second step, you need to specify the location where the project you are about to import should be stored on your computer. Normally, this would be the same directory where all your VIAN projects lie, by default: /<path>/<to>/VIAN/projects. In most cases, you can simply accept the default folder VIAN suggests to you.

  • Thirdly, VIAN needs to know where the corresponding movie for the project file lies. Due to propriety issues, the VIAN WebApp cannot provide you the movie file with which the project was generated. Therefore, you must obtain the correct movie file by yourself. Note that it is well possible that even if you have the correct movie that this file might still slightly differ from the file with which the project was generated; in consequence, there might be small incorrections like slightly offsetted screenshots and segmentations and the like.

After importing the project file, specifying the project directory and movie path, you can explore the project in VIAN directly - e.g. check out the annotations of segments.
