A good before-and-after video tells a clear story: here was the problem, here is what changed, here is how. These Synthesia AI prompts for before and after videos help you plan scripts, scenes and presenter notes for process transformations, software workflow upgrades, home organisation projects, design refreshes and training outcomes. One boundary applies throughout: every "after" must be real and verifiable. This guide does not help with fabricated results.
How Synthesia works for before-and-after videos
Synthesia is an AI video platform where you type or paste a script and a digital avatar presents it, usually alongside slides, screen recordings or images. Available avatars, templates, languages, editing controls and pricing change, so check the tool's current features and licence terms.
Synthesia does not know your results. You supply the true "before" and "after" footage, screenshots, metrics or photos, and the avatar narrates the story around them. The prompts here are for the script and structure, which you can draft in a chat assistant and then paste into the video tool.
Honest before-and-after rules
- Use real evidence you can show: screenshots, dated metrics, genuine photos.
- Describe conditions. State timeframe, method and anything else that influenced the outcome.
- No guarantees. "Results vary" should be true and visible when it matters.
- Be careful with sensitive claims. Health, fitness, finance and cosmetic results need real, verifiable proof and must follow platform ad rules and local law. If in doubt, do not make the video.
- Avatars and consent. Use stock avatars within the tool's terms, or a custom avatar only with the person's written consent. Consider disclosing that the presenter is AI-generated.
- Never stage a fake transformation or edit images to exaggerate.
The before-and-after prompt formula
[Video goal] + [audience] + [the real "before" situation] + [the real "after" situation with proof source] + [what changed and how] + [honest caveat] + [length and tone] + [output format]
| Part | Example | |—|—| | Before | support inbox took 2 days to answer | | After | average first reply in 4 hours, from our helpdesk report | | Proof | screenshot of dated report on screen | | Caveat | team also grew by one person |
Basic prompt vs improved prompt
Basic:
Write a before and after video script about our new process.Improved:
Fill in the blanks below, or click a highlighted word in the prompt.
Write a 75-second script for an AI avatar presenter explaining a before-and-after of our [PROCESS NAME] to [AUDIENCE]. Before: [REAL BEFORE SITUATION, with timeframe]. After: [REAL AFTER SITUATION], supported by [PROOF SOURCE, e.g. our monthly report for MONTH]. Explain the three changes we made. Include one honest caveat: [FACTOR THAT ALSO CONTRIBUTED]. Tone: calm, practical, not salesy. Output a two-column table: spoken line and on-screen visual (including which real screenshot or footage to show).Why it works: it ties each claim to a proof source and includes a caveat, which builds credibility.
Process and workflow transformations
1. Workflow overhaul
Fill in the blanks below, or click a highlighted word in the prompt.
Draft a 60-90 second script for an AI presenter showing a before and after of our [WORKFLOW]. Scene 1: the old process in [NUMBER] steps with its real pain points (time, errors, handoffs). Scene 2: the new process with [TOOL OR CHANGE]. Scene 3: the measured result from [SOURCE] over [TIMEFRAME]. Scene 4: one limitation or thing we are still improving. Table output: scene, narration, on-screen visual, proof to show.2. Software setup comparison
Fill in the blanks below, or click a highlighted word in the prompt.
Create a script explaining how our team moved from [OLD METHOD, e.g. spreadsheets] to [NEW TOOL]. Cover: what was slow or error-prone, what we changed, how long migration took, and what the team says now (use only these real notes: [PASTE NOTES]). Keep it neutral, name trade-offs, and avoid claims we cannot show on screen.For ideas to speed up your own processes, see AI prompts for workflow automation.
3. Training outcome video
Fill in the blanks below, or click a highlighted word in the prompt.
Write a script for a short internal video showing a before-and-after for [TRAINING PROGRAMME]. Before: skills assessment findings from [DATE]. After: findings from [DATE] using the same assessment. Present only the numbers from [SOURCE], mention the sample size, and explain what the training did not fix. Warm, respectful tone, under 90 seconds.Space, design and product-refresh videos
4. Room or office refresh
Fill in the blanks below, or click a highlighted word in the prompt.
Script a 45-second before-and-after for a [ROOM OR OFFICE] makeover. Before: describe the real problems (storage, light, layout). After: describe what was actually changed, with budget range [ACTUAL RANGE] and time taken [ACTUAL TIME]. Add on-screen captions for each change. Friendly, practical voice. Table: narration, real photo to show, caption text.5. Website or design redesign
Fill in the blanks below, or click a highlighted word in the prompt.
Write a script showing a website redesign for [PROJECT]. Before: three real issues from user feedback or analytics (cite source and date). After: three real design changes with screenshots. Report one measured metric from [SOURCE] over [TIMEFRAME] and state that other changes happened in the same period. Tone: clear, professional.6. Product version update
Fill in the blanks below, or click a highlighted word in the prompt.
Create a before-and-after script comparing version [OLD] and version [NEW] of [PRODUCT]. List only the real changes from our release notes: [PASTE NOTES]. Explain each in one sentence of plain language, show the matching screen, and finish with who should upgrade and who might not need to. Do not mention any feature not in the notes.Customer and case-study stories
7. Customer case study (with permission)
Fill in the blanks below, or click a highlighted word in the prompt.
Write a 90-second script based on this approved customer case study: [PASTE APPROVED TEXT]. Structure: situation before, what they did, outcome after, with direct quotes only if provided in the text. State the timeframe and any other factors they mentioned. Do not add numbers, quotes or claims that are not in the source. End with a line inviting viewers to read the full case study.8. Service process transformation
Fill in the blanks below, or click a highlighted word in the prompt.
Draft a script showing how our [SERVICE] changed from [OLD METHOD] to [NEW METHOD]. Include customer-facing differences (speed, communication, clarity), what we measure, and what we still handle manually. Honest, conversational tone with no exaggerated promises.Avatar scenes and shot direction
9. Scene-by-scene storyboard
Fill in the blanks below, or click a highlighted word in the prompt.
Convert this script into a storyboard table for an AI-avatar video: scene number, duration in seconds, avatar position (full screen, left third, hidden), narration, on-screen visual (real footage, screenshot or slide), caption text, and a note on proof used. Keep scenes under 15 seconds. Script: [PASTE SCRIPT]10. Split-screen layout plan
Fill in the blanks below, or click a highlighted word in the prompt.
Plan a split-screen "before" and "after" segment: left side shows [BEFORE ASSET], right side shows [AFTER ASSET], with the avatar narrating beneath. Specify timing, labels ("Before, MONTH/YEAR" and "After, MONTH/YEAR"), caption wording and what text must appear to ensure the comparison is fair (same angle, same scale, same conditions).Multi-step workflow: script to publish
- Gather proof, then list it:
Fill in the blanks below, or click a highlighted word in the prompt.
I have this real evidence: [LIST FILES, DATES, METRICS]. Tell me which claims it can support, which it cannot, and what extra evidence would make the comparison fairer.- Draft with prompt 1, 4 or 7.
- Run a claims audit:
Review this script and list every factual claim. For each, state the proof I need to show on screen and flag any claim that sounds like a guarantee or an unverifiable result. Suggest safer wording.- Build in Synthesia using stock or consented avatars.
- Check platform rules for ads or regulated topics, then publish with an AI-presenter disclosure if appropriate.
For short-form edits, see AI prompts for scroll-stopping social media posts.
Tips and common mistakes
- Show the proof on screen. Narration alone is not evidence.
- Keep comparisons fair: same measurement, same scale, similar conditions.
- State the timeframe.
- Common mistake: claiming one change caused the whole result.
- Common mistake: cropping or filtering the "after" image only.
- Common mistake: making health, fitness or finance promises you cannot verify.
- Keep scripts short. Aim for one idea per scene.
