Compares two video edit decision list (EDL) snapshots to detect and report differences between editing states across cuts, transitions, and timing.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability halowerk-medienwerk-edit-decision-list-snapshot-compare-b44f8ea2 -d '<json body>'
```

Example prompt: Can you compare these two edit decision list snapshots from my video project — the rough cut EDL and the final cut EDL — and tell me exactly which cuts, transitions, or timings changed between them?

## When to prefer this

Choose this endpoint when you need to programmatically diff two edit decision list snapshots from the same video project — particularly for post-production QC, revision auditing, or change tracking workflows. It is purpose-built for EDL-level comparison rather than raw video frame diffing (use the scene-change endpoint for that) or document text comparison.

## Known failure modes

- Invalid or unparseable EDL format returns a parsing error
- URLs that are inaccessible or fail SSRF safety checks return a fetch error
- Base64-encoded content that is malformed or too large returns a size or decode error
- Snapshots with incompatible EDL formats that cannot be aligned return a comparison error
- Missing required snapshot inputs return a 400 validation error
