Case 02 / Crisis verification
Old video shared as a new event
Test whether a crisis video is actually from the claimed event by checking first publication traces and visual context.
Real-case basis: Old and unrelated videos recirculated during the Israel-Hamas war.
Data package
A short video shared with a crisis caption
Three to five keyframes from the clip
Visible language, logos, weather, uniforms, terrain, or event signs
Older copies of the same video on other platforms
Task
Extract keyframes and search for earlier copies.
Compare the earliest visible date with the claimed event date.
Write whether the video supports the new claim.
Hint
The caption may be the least reliable part of the post.
A video can be real and still be from the wrong event.
Finding an older copy is often enough to break the new claim.
Answer key
The key result is whether the video existed before the claimed event.
In the AP examples, older footage was moved into a new conflict context.
A good report separates authenticity of the video from relevance to the event.
Weak analysis example
The video looks real and was posted with the crisis hashtag, so it must show the current event.
Careful report example
Keyframe search shows the video circulated before the claimed event. Visible context also does not match the new location and date. The video may be real, but it does not verify this incident.
