Choose frames with a purpose
Look for readable signs, an unusual object or a stable wide shot. Avoid transition frames and motion blur. Preserve the video's URL and timestamp before extracting anything, and only work with footage you are entitled to examine.
Build a small frame set
- Capture a clear opening or establishing shot.
- Capture a later frame with different useful detail.
- Search each separately without generated enhancement.
- Compare the full candidate videos when available.
A clip described as today's storm might contain a frame that also appears in an older public video. That is a reason to compare sequences, landmarks and publication context. It is not enough to assume that two similar skies depict the same event.
Preserve uncertainty
Record the timestamp of the frame you searched and the exact candidate URL. A search result's date may reflect a repost or crawl rather than the recording date. Avoid identifying private people from frames; focus the investigation on the footage's source, event claim or permitted reuse.
