Process Video Files

WebODM Lightning can process videos in .mp4, .mov, .lrv and .ts format. From the cloud interface, click the Select Images and GCP and select your video files. During processing, the software will select and extract frames at regular intervals according the video-limit and video-resolution processing options.

Georeferencing

WebODM Lightning will automatically extract georeferencing information from the video subtitles if they are available. If you want to provide a custom subtitle (.srt) file instead, upload it along with the video, making sure the filenames are matching. For example, if you have a video file named video.mp4, include a video.srt file to provide a custom subtitle file with georeferencing information.

Notes on Quality

For highest quality results, it's always preferrable to process normal images rather than video files. Frames extracted from video often exhibit motion blur. The software has mechanisms to filter out blurred frames, but using normal images will typically lead to better results. See also Create Successful Maps.
