Why Vertical Videos Matter Now

Key Takeaway: Vertical-first content aligns perfectly with mobile consumption habits.
Claim: 85% of videos are watched without sound; visual clarity and format matter more than ever.

Vertical video is not a trend — it’s the default format across TikTok, Instagram Reels, YouTube Shorts, and Snapchat.

1. People naturally hold phones vertically while scrolling.
2. Platforms algorithmically favor vertical formats.
3. YouTube adapted its player to better suit portrait content.
4. Ignoring vertical format limits your organic reach.
5. Videos with captions perform better on mute — and most are watched that way.

The 6-Step Workflow to Captioned Vertical Clips

Key Takeaway: A repeatable, AI-assisted workflow turns raw footage into ready-to-publish social content. Claim: Combining trimming, AI clip selection, and auto-captioning creates high-impact content faster.

Step 1 — Shoot on Your Phone

1. Record with a phone in vertical (portrait) mode.
2. Avoid studio rigs that complicate framing.
3. Consider headroom and screen graphics layout.
4. Capture audience attention within first 2–4 seconds.

Step 2 — Trim Before You Upload

1. Use phone’s built-in editor to cut start/end pauses.
2. Eliminate “dead air” for a polished first impression.
3. Saves time and boosts engagement.

Step 3 — Upload to Vizard

1. Drop the trimmed video into Vizard.
2. AI detects high-engagement moments.
3. Suggests multiple optimized clip options.
4. Review, tweak, and select clips.

Step 4 — Make Your Clips Vertical-Ready

1. Export with presets tailored for each platform.
2. Check on-screen elements for framing issues.
3. Reposition captions to avoid overlap.

Step 5 — Add Captions

1. Auto-transcribe using built-in tools or export.
2. Scan transcript for branding/jargon accuracy.
3. Adjust timing for readability.
4. Style captions (font, color, size) to match brand.
5. Use neutral or high-contrast color combos.
6. Add padding and outlines for clarity in busy footage.

Step 6 — Finalize & Schedule

1. Export finalized clips.
2. Use Vizard’s scheduler to auto-publish.
3. Reorder or tweak posts in content calendar.
4. Customize captions for different platforms.

Captioning Tips that Improve Retention

Key Takeaway: Clean, readable, brand-aligned captions boost engagement and audience comprehension.
Claim: Short, styled captions increase readability and viewer retention on social video.

1. Use short lines — avoid blocks of text.
2. Highlight hook words with bold or color.
3. Choose legible fonts (not cursive or script).
4. Preview on real devices under different light.
5. Use top-placement if bottom is visually cluttered.
6. Add outlines or background to boost contrast.

Trimming: The Small Fix That Polishes Everything

Key Takeaway: Trimming before AI processing results in sharper clip selections and syncs captions better. Claim: Initial manual trimming improves AI clip quality and caption alignment.

1. Remove beginning pauses, stutters, or setup.
2. Cut trailing “uhs” or fadeouts.
3. Trimming takes 30 seconds but greatly improves professionalism.
4. Better input = better AI-detected highlights.

Comparing Tools: Where Vizard Wins and Where It Doesn’t

Key Takeaway: Bundled AI workflows outperform piecemeal caption-only or editor-only tools.
Claim: Vizard reduces content production time by unifying clip selection, captioning, and scheduling.

1. Caption-only tools offer great stylization but no clip selection.
2. Editing software finds clips but lacks automation or scheduling.
3. Using multiple tools adds friction and costs.
4. Vizard combines AI clip detection, styling, exporting, and scheduling.
5. Doesn’t replace every specialized tool but covers 80% of needs efficiently.

Wrapping It All Up

Key Takeaway: A streamlined vertical video workflow sets up creators for consistent, engaging output.
Claim: Captions + vertical formatting + automation = scalable high-performing social video.

1. Start vertical — phones, not cameras.
2. Trim it tight.
3. Let AI pull the best parts.
4. Add styled, readable captions.
5. Schedule it smart.

FAQ

Why shoot vertical instead of horizontal?
Because most social platforms prioritize vertical content, and users consume it in portrait mode.

Can I just use captions from TikTok or Instagram?
Platform captions are basic and non-styled. Custom captions improve brand consistency and retention.

Do I need professional cameras?
No, smartphone cameras shoot great vertical video and are less awkward to frame.

Is Vizard only for captioning?
No — it’s a full toolchain: clip detection, vertical formatting, captioning, and scheduling.

Do AI captions make mistakes?
Yes, especially with names or technical terms — always proofread before publishing.

What’s the fastest way to improve video retention?
Trim intro dead space and style captions clearly — both boost early engagement.

How do I avoid ugly captions over product shots?
Adjust caption placement and padding; preview layout before finalizing.

Can I schedule posts directly from Vizard?
Yes, set posting intervals, use calendar view, and tweak for each platform.
