How to turn silent phone footage into a behind-the-scenes post

Last updated 2026-08-16 · 6 min read

What is the short version?

Small businesses film constantly and post almost none of it, because a silent twelve-second clip of someone working is not a post yet. What turns it into one is music, a grade, a name and a tagline — four small things that take an evening to do by hand.

1. Go to Vizard Agent and upload the clip, even with no sound.
2. Give the business name and the tagline exactly as they should read.
3. Say the feed and roughly how long the post should be.

What do you need before you start?

The footage and your wording. Vizard Agent handles the music, the grade and the typography, so the two things only you can supply are the clip and the exact text — which matters more than it sounds, because a tagline set in type is unforgiving of a typo.

• The clip. Silent is fine. Vertical phone footage is the normal input.
• The business name. Spelled and capitalised as you use it everywhere else.
• The tagline. Written out exactly. Read it twice before sending.
• Your logo, if you have one. Vizard Agent will place it rather than setting the name in plain type.
• The mood. Upbeat, warm, calm. This picks the music, which sets the whole feel.

What do you type into Vizard Agent?

Say what the business is and give the exact wording. Vizard Agent looks at the footage to work out what is happening in it, so a short brief about the brand does more than a description of the shots it can already see.

Prompt

Variants worth knowing:

• With your logo. Upload it and Vizard Agent uses the mark instead of setting the name in type.
• Captions describing the process. Useful when the footage is not self-explanatory.
• A set of posts. Send several clips and ask for one post each, in a consistent style.

What does Vizard Agent actually do?

Here is the order Vizard Agent worked in on a real behind-the-scenes post. It spends the first third confirming basic facts about the footage — including whether the frame is really the way round it appears — before choosing anything creative.

1. Probes the footage for resolution, duration and stream properties.
2. Extracts frames and looks at the contact sheet to see what is happening.
3. Analyses the video and its audio content, confirming there is nothing usable on the sound track.
4. Checks the dimensions and the rotation flag, then verifies a frame is genuinely the right way up.
5. Extracts a timeline grid of frames and reviews the clip's shape over time.
6. Lists the available fonts before designing any typography.
7. Searches the music library across several moods and downloads candidate tracks.
8. Analyses each candidate's vibe against the footage rather than picking by title.
9. Tests the colour grade on stills before applying it to the whole clip.

Steps 4 and 9 are the unglamorous ones. Phone footage lies about its orientation often enough to be worth checking every time, and a grade tested on one frame costs seconds where a grade tested by rendering costs minutes.

What does the result look like?

From the run this page is written from, probed on the delivered file: 1080x1920, H.264, 30fps, 11.6 seconds, AAC audio. Vertical, under twelve seconds, graded, scored, with sparkle sound effects and the business name and tagline set on screen — from footage that arrived with no sound at all.

Ask for a second version with different wording and Vizard Agent re-renders the typography over the same graded cut rather than starting again.

Twelve seconds is the right size for this format. It is long enough to show a process happening and short enough that nobody has to decide whether to keep watching, which is the decision most business posts lose.

How long it takes was not measured separately here. Comparable work runs a median of 28 to 38 minutes end to end, and the upper quartile is several times the median. Across all projects the median cost by tier is Flash 47, Pro 55, Max 242, Ultra 263 credits.

When does this not work well?

A post like this is a frame around your footage, and the frame cannot rescue what is inside it. Vizard Agent grades, scores and titles whatever you send, and twelve seconds of shaky, badly lit filming is still twelve seconds of shaky, badly lit filming afterwards.

• Very short clips limit everything. Under about eight seconds there is not enough to cut.
• Dark or shaky footage stays that way. A grade improves colour; it does not add light or stability.
• Faces need permission. Staff, children and customers in the background are a decision, especially for a family business.
• A tagline is set in type. Check the spelling before you send it, because it will be rendered exactly as written.
• Music has to fit the trade. Upbeat pop under a quiet craft process reads as a stock advertisement.
• One clip is one post. A week of content needs a week of filming, not a longer edit of the same twelve seconds.

How do you fix a result that came back wrong?

Say which element. Vizard Agent keeps the graded footage, the music candidates it downloaded and the typography as separate layers, so changing the tagline or swapping the track leaves the grade and the timing exactly where they were.

• "Change the tagline wording." The type is re-rendered over the same cut.
• "Use the other track." A music swap; nothing else moves.
• "Warmer grade." Re-tested on stills, then re-applied.

How does Vizard Agent compare to doing it yourself?

By hand this is a mobile editing app, a music track that may or may not be licensed, and typography squeezed in with a finger. It is thirty minutes you do not have at the end of a working day, which is why the clip stays in the camera roll.

Common questions

Does the footage need sound? No. Vizard Agent checks whether there is usable audio and scores the clip when there is not.

Will it fix sideways video? Yes. Vizard Agent checks the rotation flag and verifies a frame before building anything.

Can it use my logo? Yes. Upload it and Vizard Agent places the mark rather than setting your name in plain type.

How long should a post be? Ten to fifteen seconds for this format. Longer needs a reason to keep watching.

Can I send several clips at once? Yes. Ask for one post each and Vizard Agent keeps them consistent with one another.

Is the music licensed? Vizard Agent searches a licensable library rather than pulling a track from a feed.

Can it add captions describing the process? Yes. Say what is happening in the clip and Vizard Agent writes short captions over the footage.

Does it need my brand colours? Only if you have them. Otherwise Vizard Agent takes its palette from the footage and your logo.
