Stock B-roll is fast; sometimes it is wrong. A generic “business handshake” clip undermines a story about your specific workshop. When you need shots of your product, team, or neighbourhood, you should film and upload your own B-roll. The Simple Video Editor treats custom files the same way as stock — library lane first, then onto the Video 1 timeline.

When custom B-roll beats stock

Product demos where packaging, colour, and scale matter.
Local services where geography is the selling point.
Process proof — cleaning, cooking, assembling, delivering.
Testimonials where the client’s site must be recognisable.
Regulated claims where stock could misrepresent what you actually do.

Tips for filming usable B-roll (phone is enough)

Landscape orientation for YouTube; vertical only if you edit exclusively for Shorts. Lock exposure where possible; avoid strobing shop lights. Film each shot five to ten seconds longer than you need — editors love handles. Capture detail (hands), context (room), and movement (walking, pouring, typing).

Use natural light near a window; face the window, not your back.
Wipe the lens — seriously.
Record ambient sound even if you mute it later; some cuts feel dead without room tone.
Repeat the same action twice from two distances.

How to upload B-roll in the editor

Open Simple Video Editor.
Complete Step 1 (Video 1) so the tool unlocks B-roll upload.
Use the B-roll file control in Step 3 — MP4, MOV, or WebM within practical browser limits.
Your clip appears on the B-roll library lane with filmstrip thumbnails.
Drag the segment onto Video 1 at the moment you want the cutaway.
Preview with playhead scrubbing; adjust placement by dragging the block.

You can mix custom uploads with keyword-fetched stock in the same project — custom for proof, stock for abstract concepts you never filmed.

Mixing custom and AI-suggested B-roll

Transcribe or paste your script so keyword matching proposes searches; accept only clips that fit. Filmed B-roll should cover anything specific; let stock cover “city skyline”, “teamwork”, or “laptop” if those phrases are generic in your script.

File size and performance

Browser FFmpeg editing is happiest with short, compressed MP4 files. If 4K phone footage stutters, transcode to 1080p in a free converter before upload, or trim in the phone’s photos app first.

Organising a personal B-roll library

Create folders on your phone or PC: product, process, people (with consent), place. Name files with date and topic — `2026-06-oven-clean-before.mp4` beats `VID_0042.mp4`. Once a month, film “maintenance B-roll” with no script: ten clips you can use for months.

Consent and privacy

If staff or customers appear, get permission suitable for your use. Blur licence plates if your insurer or policy asks. Do not film confidential screens or documents — use staged props instead.

Colour and brand consistency

Wear the same apron or hang the same backdrop when you batch film. Custom B-roll reinforces brand colour in a way stock rarely does. Place clips after sentences that mention your guarantee, your city, or your process — viewers link the image to the claim.

Pairing uploads with stock search

In the Simple Video Editor, upload your ten best clips first, then use keyword fetch only for gaps — “meeting”, “deadline”, “celebration”. That order stops you accepting mediocre stock when you already own perfect footage.

Shot list you can film in fifteen minutes

Hands using your main tool or product.
Wide shot of workspace or vehicle.
Customer handshake or thank-you wave (with consent).
Detail of label, screen, or certificate.
Walking shot toward your building or van.

Store clips in cloud backup; losing a phone should not delete your only B-roll library.

Common upload issues

If the browser struggles, shorten clips on the phone first. MOV from iPhone is fine; very high bitrate files may stutter on older laptops. Refresh the page once if thumbnails stay black — the editor retries FFmpeg frame extraction. Place custom B-roll on Video 1 only when you want viewers to see it; leaving it on the library lane alone does not change the export.

Reuse clips across campaigns

One good five-second clip of your product can appear in ten videos. Viewers rarely remember a cutaway from three months ago. Build a “greatest hits” folder and treat it like a micro stock library you own outright.

Vertical vs horizontal B-roll

Film horizontal for YouTube and your website; crop carefully if you repurpose for Shorts. Vertical B-roll of a product can work inside a horizontal frame with blurred sides, but plan that in advance — do not assume you can fix aspect ratio in the browser editor without quality loss.

Working with a co-founder or VA

Share a written shot list and naming convention so anyone can upload into Step 3. Your editor only needs the MP4 files and a note saying which sentence each clip supports. That keeps brand visuals consistent even when you are not the person clicking Export.

Insurance and safety footage

Trades showing ladder work, electrical panels, or kitchen gas fittings should film procedures you are qualified to perform. B-roll of the correct PPE and tools builds trust; stock of generic “worker” may show the wrong kit for UK regulations. Your own five-second clip of a labelled van or certificate on the wall often outperforms cinematic stock.

Mixing uploaded B-roll with two cameras

A common weekly workflow: sync wide and close on Video 1, place custom product B-roll at chapter three, fetch one stock skyline when you mention “nationwide delivery”. All three visual tricks live on one timeline row; audio never leaves Video 1.

File naming for faster uploads

Name files `topic-action-date.mp4` — `packing-order-2026-06-02.mp4`. When you return months later, you will find the clip instantly. Delete blurry takes; a library of twenty great five-second clips beats two hundred mediocre ones.

Before/after and testimonial B-roll

Service businesses win trust with before-and-after pairs: same angle, same lighting, different outcome. Film both on the same visit. Upload as two clips and place them back-to-back on Video 1 while the client’s quote plays from Video 1 audio. No stock handshake required.

Lighting quick fixes

If footage is dark, re-film near a window rather than fighting brightness only in export. The browser editor scales and trims; it is not a full colour suite. One well-lit afternoon of B-roll filming saves hours of frustration later. Stable exposure matters more than cinematic contrast for how-to videos today.

Next step

Film ten short clips this week, upload them in the Simple Video Editor, and place one custom cutaway in the first minute of your next publish. Viewers can tell the difference immediately.
