Evidence, RAW Data & Review

The result should be supported by original evidence.

A photo finish system is not only judged by the image it shows on screen. It should also protect what was originally captured, because that original evidence may matter if a result is questioned later.

What “evidence” means on race day

A serious photo finish workflow has a chain: meeting or race setup, recording, image review, evaluation, result-list handling, export, print or display output, and later file management. That chain matters because the official result should be traceable back to the captured finish-line evidence.

For buyers, “RAW” should be understood as an evidence principle rather than a promise about a specific file format. The important distinction is between the original captured image data, the operator’s review view, and the exported image or result that gets shared. A system can have excellent review tools and still needs to preserve what was originally captured.

Capture

The source recording should belong to the correct meeting, event, heat, or race file. If a system lets the operator start recording directly, recover missed arrivals, or import recorded footage into a race file, the buyer should understand how that file is named and stored.

Review

Review software may include main evaluation views, overview windows, zoom, brightness or contrast adjustments, markers, lane or bib evaluation, and result-list fields. These are tools for interpretation. The buyer should ask whether the original image remains available after these review choices.

Export

Exports are useful for reports, officials, media, or archives, but they are not the same as source evidence. Ask whether exported JPG, BMP, lists, printed images, or public results can be traced back to the original recording.

Audit trail

Some workflows include logs, imported participant lists, edited heat-list fields, display outputs, or networked evaluation stations. Each step should make the result clearer, not make it harder to explain where the decision came from.

A strong evidence workflow lets officials reopen the race, inspect the finish, explain the judging point, and show the result without losing the original context.

Visual explanation: source evidence vs export

SourceOriginal capture

The protected recording used to review the finish and support the result later.

ReviewOperator view

Zoom, markers, brightness, and participant data help interpret the evidence.

ExportShared output

An image, list, report, or file for officials should trace back to the source evidence.

Race-day scenario: a result is disputed after the race

If a coach, rider, athlete, or official asks how a close result was decided, the team should be able to reopen the evidence, show the judged finish point, and explain which export came from which original recording.

Evidence archive checklist

  • Confirm the race file, heat, or event name before recording is archived.
  • Keep the original captured evidence separate from presentation exports.
  • Record who reviewed the finish and which judging point was used.
  • Save the image or report officials need, then confirm it can be traced back to the source evidence.

Plain answer: the system should keep the source evidence, not only the final picture that gets exported or shared.

Archive checklist

Ask where original evidence is stored, how files are named, who can reopen them, and how long the event keeps them.

Export checklist

Confirm which images, lists, reports, or result files officials need and how each export links back to the source evidence.

Review record

The team should be able to explain what the operator reviewed, what was adjusted for visibility, and why the result was chosen.

RAW as a principle

Use RAW to mean protected original evidence, not a universal promise about one file format across every timing system.

Why this matters

A beautiful export is not the same as strong evidence.

An exported image can be useful for publication, reports, or social media. Original evidence is what supports the decision if someone asks how the result was made.

Key takeaway

Good photo finish workflow protects the original evidence while making review clear and practical.
