 ### Sources of Error
-While SSOSS does provide approximate sight distance images, their are various sources of error that should be try to be minimized. Here are the major sources of error and how they can be mitigated.

+Create a gif from multiple images around the sight distance location. This can be helpful if the lens is out of focus or a few frames are obstructed.
 
 Include the -- gif flag in the command line to create. Note: this requires additional processing time for large video files.
 Use --gif-overwrite to replace an existing GIF and --no-gif-cleanup to keep the extracted frames.
