SafeReel vs Sightengine for video moderation

Sightengine is one of the most established content-moderation APIs, and for broad multi-class moderation it is a strong product. This page is about the one job SafeReel is built for — detecting pornographic content in video — and where the two differ enough to matter. Sightengine figures are quoted from sightengine.com/pricing, checked 4 September 2026.

The decisive difference: file size

Sightengine's plan comparison lists a maximum video size of 50 MB on Starter ($29/mo) and 500 MB on Pro ($99/mo). Live-stream moderation requires Pro.

SafeReel has no file-size limit. You submit a public URL and SafeReel fetches the file itself, so a 4 GB upload is the same API call as a 4 MB one. Nothing is uploaded through your server.

If your platform accepts long or high-bitrate video — recorded sessions, screen captures, full-length uploads — this is usually the whole decision. A 2 GB file cannot be submitted to Sightengine's Starter or Pro plans at any price.

Pricing models are not directly comparable

Sightengine bills operations: one model run on one image is one operation, and video is charged by sampled frame at a configurable 0.5–2 fps. At 1 fps and the published $0.002 overage rate, a video-minute works out to about $0.12 — a derivation, not a Sightengine quote. See the full pricing comparison for the working.

SafeReel bills €0.020 per video-minute, per second, and caps billing at 20 minutes per video regardless of length. A 90-minute file costs €0.40.

The practical consequence: Sightengine's cost scales with duration without limit, SafeReel's does not. On short clips the gap is modest. On long-form video it is large.

Where Sightengine is the better choice

Be honest about this — it often is:

• You need more than adult content. Sightengine covers 120+ classes: violence, gore, weapons, drugs, hate symbols, self-harm, alcohol, tobacco. SafeReel detects pornographic content and nothing else.
• You need live-stream moderation. Sightengine moderates live streams on Pro. SafeReel does not do live streams at all.
• You need frame-level timestamps for partial redaction. Sightengine returns timestamped detections so you can cut or blur segments. SafeReel returns a verdict for the video.
• You need text, OCR, deepfake or AI-generation detection. Sightengine has all of these. SafeReel has none of them.
• Your files are small and your volume is low. At 50 MB clips and a few thousand operations a month, Sightengine's included quota may simply cost less.

Where SafeReel is the better choice

• Large or long videos. No file-size limit, full-duration analysis, and a 20-minute billing cap.
• Video already hosted elsewhere. Submit an S3, R2, CDN or origin URL — see the S3/R2 guide. No upload path to build.
• Cost on long-form content. €0.40 for a feature-length film, flat.
• You want the accuracy number with its methodology. SafeReel publishes 95.5% accuracy, 92.2% recall and 0.41% false positives on 1,089 production videos, caveats included: accuracy report.
• Retention matters to your DPA. Image bytes live only in request memory; video frames are deleted within minutes of the verdict. Nothing else is kept but verdicts, counters and non-reversible hashes. See Trust.

What SafeReel deliberately does not do

Stated plainly so you can rule it out fast: no CSAM detection, no age determination, no non-explicit nudity or swimwear classification, no text moderation, no live streams, no on-premise deployment (managed single-tenant deployments are available instead).

Try it against your own files

The playground runs image checks with no signup. For video, a free key gives you 100 video-minutes a month — enough to run your real back-catalogue samples through both services and compare verdicts on content you actually host, which is the only benchmark that means anything.
