How to gate a Sora / Veo render pipeline on quality before it publishes

To gate an AI video pipeline on quality, run UploadCheck as a required check against the exported clip and fail the pipeline unless the verdict is PASS. The CLI and GitHub Action exit non-zero on a BLOCK, and a PASS produces a signed receipt bound to the file's sha256 — so a broken Sora, Veo, Kling, or Runway generation never reaches your audience.

The gap: generation has no publish gate

An automated video pipeline is a loop: prompt, render, maybe stitch a few 8-second shots, export, publish. Every step is code — except the one that decides whether the output is good enough to ship. That's usually a human glancing at it, or nothing.

Generative video fails in specific, repeatable ways: the picture warps or "boils" between frames, a frame freezes at a stitch seam, audio drifts out of sync with the mouth, ambience cuts to dead air where two shots join, loudness lands off-target. Ship one of those to a paying end user and you eat a refund, a re-render, and a support ticket — after the fact.

The fix is the same one code pipelines already use: a required check that blocks the publish step until quality passes. UploadCheck is that check for media.

Gate it in one step

Check the export against the ai_render_gate profile — the named delivery target that runs the temporal-artifact and technical-readiness gates for generated video (ai_warp, flicker, loop_freeze, av_sync, loudness, clipping, dead_air, black_frames, canvas_fill, format_spec).

# Fails the pipeline on a BLOCK verdict; writes the signed receipt
uploadcheck check render.mp4 \
  --profile ai_render_gate \
  --fail-on block \
  --receipt uploadcheck-receipt.json

In GitHub Actions:

- uses: uploadcheck/action@v1
  with:
    file: out/render.mp4
    profile: ai_render_gate
    fail-on: block
    receipt-path: uploadcheck-receipt.json
    api-key: ${{ secrets.UPLOADCHECK_API_KEY }}

Exit code 2 on BLOCK fails the job; on PASS it continues and leaves a signed receipt for the publish step to require. An agent does the same through MCP — call qc_run_local_file, then qc_get_receipt, and gate its publish action on receipt.verdict === "PASS".

Fix only the shot that failed

A BLOCK isn't a dead end — it's a work order. The report names the failing gates and the exact timestamps: audio desync at 0:06, a frozen frame at the 0:08 stitch seam, warping at 0:11. Regenerate only that shot, re-export, and re-check. Re-checks of the same file don't burn extra minutes, so the generate → check → regenerate loop is cheap to run until the clip earns a green receipt.

Won't it block my good clips?

The whole point of a gate is that it doesn't cry wolf. UploadCheck's temporal-artifact gates are tuned conservatively: on a 40-clip corpus of real, good AI-generated video, ai_warp and flicker produced zero false positives — they didn't BLOCK clean output.

Why the receipt matters here

Exit codes gate the run; the signed receipt makes it provable and portable. It binds the PASS verdict to the file's sha256 and the ai_render_gate profile, so a downstream deploy, an auditor, or a client can confirm — with a single no-auth call — that this exact file passed this exact spec. That's what lets an AI video pipeline run unattended: generate, gate, publish, and prove every clip passed.
