How to make a safety reel from footage of work being done unsafely

Last updated 2026-09-17 · 8 min read

What is the short version?

Site footage is filmed wide, because that is how you see the job. A safety clip is watched on a phone, where a wide shot means the hazard is four millimetres tall and nobody can see what you are warning them about.

1. Tell Vizard Agent exactly what is unsafe in the footage.
2. Say where it will be shown and in what language.
3. Ask for a clean version with no text as well.

What do you need before you start?

The clips and a plain statement of the hazard. Vizard Agent reads the footage itself, but a sentence like "they are working at height with no harnesses" tells it which figures matter in a frame that is mostly scaffolding, roof tiles and sky, and that changes every crop it chooses.

• The clips. However many, however wide.
• The hazard. Named plainly.
• The audience. A crew briefing, a client, social.
• The language. For the hook and the warning card.
• Whether text is wanted. Some briefings prefer none.

What do you type into Vizard Agent?

Give it the title and the concept in one line. A safety reel has a shape — a hook, the evidence, a warning — and naming that shape up front is faster than correcting a general edit afterwards.

Prompt

Variants worth knowing:

• "Where you can see there is no harness." The selection rule.
• "End on a warning card." The structure, in four words.
• "Keep the site sound." Atmosphere, at a level that leaves room.

What does Vizard Agent actually do?

Here is the Vizard Agent sequence on four clips of roofing work turned into a one-minute vertical reel. A surprising share of the effort goes on a single question that has nothing to do with editing: whether the workers are still inside the frame after the crop to vertical.

1. Samples all four clips into one review sheet and picks the strongest moments.
2. Checks each clip for worker visibility rather than for general quality.
3. Inspects closer roof crops to see whether vertical framing keeps the workers readable.
4. Rebuilds the review sheet after correcting timestamps that fell outside a clip.
5. Measures the ambience level in each clip separately before mixing.
6. Builds a short vertical hook that reveals the first scene.
7. Assembles the four sections and a closing warning card, keeping the natural sound.
8. Finds a long line hitting the edge of frame and re-flows it onto two lines.
9. Produces a clean version with no explanatory text, keeping only the title hook.
10. Re-checks the vertical crops to confirm the workers stay in frame in the later shots.
11. Renders a full-screen vertical version with a gentle pan where the camera drifts.
12. Runs a final motion and sync check on the uploaded copy.

Step ten is the one that matters most and gets skipped most. A crop chosen on the opening frame is correct for two seconds; the workers move along the roof, the camera drifts, and by the end the hazard is outside the frame while the reel still claims to be showing it.

Step five is why the warning lands. Site ambience is loud and uneven across clips, so Vizard Agent measures each one and sets a level that keeps the atmosphere without competing with the point being made.

Step nine is worth asking for routinely. A version with no explanatory text can be used in a briefing where somebody is speaking over it, or subtitled into another language later, without going back to the footage.

What does the result look like?

A one-minute vertical clip that opens on a hook, shows the hazard clearly enough to be discussed, and closes on a warning. The workers are visible in every shot, the site sound is present but sits under the message, and there is a text-free version of the same cut alongside it.

When does this not work well?

Some footage cannot carry the point. If the hazard is not visible at the resolution you filmed it, or if it depends on something off camera — a missing anchor point, a permit that was not issued — no crop or caption makes the clip evidence of it.

• Hazards you cannot see. Missing paperwork, missing anchors.
• Very distant figures. Cropping in runs out of pixels.
• Faces that are identifiable. Consider blurring before sharing.
• Footage from another company's site. Check before you publish it.
• Clips too short to read. A hazard needs a few seconds on screen.

How do you fix a result that came back wrong?

Say which shot it is and what you cannot see in it. Vizard Agent adjusts the crop or the timing for that section alone, which leaves the hook at the front and the warning card at the end exactly as you approved them.

• "You lose them at the end of shot three." That crop is re-measured across the move.
• "The text runs off the edge." The line is re-flowed onto two.
• "The wind drowns the card." The ambience level is lowered under it.
• "I want no text at all." The clean version is rendered from the same cut.

How does Vizard Agent compare to doing it yourself?

By hand you crop to the middle of the frame and hope. That is the default in every editor, it works on a talking head, and on a wide site shot it reliably centres the chimney while the people you are talking about walk out of frame.

Common questions

Can it blur faces? Yes. Ask Vizard Agent and it blurs the people while keeping the hazard visible.

How long should a safety reel be? A minute is plenty, and Vizard Agent will cut to whatever length you specify.

Can I have it in two languages? Yes. The text-free version Vizard Agent delivers makes a second language straightforward.

Does it need the original audio? Not necessarily, but site sound makes the clip feel like evidence rather than a graphic.

Can it mark the hazard on screen? Yes — Vizard Agent can track an arrow or a highlight onto the figure.

Will it work from body-cam or drone footage? Yes. Vizard Agent checks readability the same way whatever the source.

Can it make a landscape version too? Yes. Vizard Agent builds it from the same cut, which keeps the two consistent.

What if I have twenty clips? Vizard Agent reviews them all and selects the clearest moments.

Should the tone be serious? Say so. A hook can be attention-grabbing without being flippant.

Can it add a company logo? Yes. Vizard Agent puts it on the closing card, where it does not cover the footage.

What about music? Usually unnecessary, and Vizard Agent will say so — site sound is more convincing.

Can I use this for a toolbox talk? That is what the text-free version is for.

Will it name the company or the site? Only if you ask. Vizard Agent leaves identifying detail out otherwise.

Can it do a positive version — the right way? Yes, and it is worth pairing them if you have both on film.
