Como Fazer Vídeos IA para Marketing em Redes Sociais

Social media algorithms reward video. Instagram Reels get 2x the reach of static posts. TikTok is video-only. YouTube Shorts drives more subscriber growth than long-form content. But creating platform-native video at scale is expensive and time-consuming. AI-generated video changes the economics entirely. This playbook covers the exact workflow for creating AI videos that perform on each major platform.

The Platform-Native Mindset

Each platform has its own language. A video that performs well on TikTok will flop on LinkedIn. A LinkedIn video will feel out of place on Instagram. The mistake most brands make is creating one video and posting it everywhere. Platform-native content means adapting format, pacing, hook style, and tone to each platform's audience expectations.

Platform-Specific Requirements

TikTok

• Aspect ratio: 9:16 vertical (mandatory)
• Length: 9-15 seconds optimal for ads, 15-60 seconds for organic
• Hook window: First 2 seconds. If you do not grab attention here, viewers scroll.
• Style: Raw, authentic, trend-aware. Over-produced content performs poorly.
• Audio: Trending sounds boost reach. Use TikTok's commercial music library for ads.

Instagram Reels

• Aspect ratio: 9:16 vertical
• Length: 15-30 seconds optimal
• Hook window: First 3 seconds
• Style: More polished than TikTok. Aesthetic matters. Clean visuals, good lighting.
• Captions: 85% of Reels are watched without sound. Always include text overlays.

YouTube Shorts

• Aspect ratio: 9:16 vertical
• Length: 30-60 seconds optimal
• Hook window: First 3 seconds
• Style: Educational or entertaining. YouTube audiences expect value.
• SEO: Title and description matter. Include keywords for discoverability.

LinkedIn

• Aspect ratio: 1:1 square or 16:9 horizontal
• Length: 30-90 seconds optimal
• Hook window: First 3 seconds
• Style: Professional, educational, insight-driven. No dancing, no trends.
• Captions: Mandatory. Most LinkedIn users watch without sound at work.

X / Twitter

• Aspect ratio: 16:9 horizontal or 1:1 square
• Length: 15-45 seconds optimal
• Hook window: First 2 seconds
• Style: Punchy, opinionated, newsworthy. X rewards strong takes.

The Hook Formula That Works Everywhere

The first 2-3 seconds determine whether your video gets watched or scrolled past. Here are the hook types that consistently perform:

1. Problem Hook

Start with a pain point your audience recognizes immediately.

Example: "Tired of spending 4 hours editing product videos? Here is how I do it in 4 minutes."

2. Result Hook

Show the end result first, then reveal how you got there.

Example: "This product video got 2 million views. Here is the AI tool I used to make it."

3. Curiosity Hook

Create an information gap that viewers need to watch to close.

Example: "I tested 10 AI video generators. Number 7 shocked me."

4. Contrarian Hook

Challenge a commonly held belief in your niche.

Example: "Stop using Runway for product videos. Here is what works better."

The AI Video Production Workflow

Step 1: Script and Storyboard

Write a 3-5 sentence script. Identify the hook, the middle (value delivery), and the CTA. For a 15-second video, that is 1 sentence per section.

Step 2: Generate Visual Assets

Use AI Video Generator to create 3-5 second clips for each section of your script. Generate multiple variations and pick the best.

Step 3: Platform-Specific Export

Use AI Ads Video to export in the correct aspect ratio for each platform. One generation, multiple outputs.

Step 4: Add Captions and Music

Use CapCut (free) to add captions, trending audio, and final polish. This takes 5-10 minutes per video.

Content Pillars for AI Video

Rotate between these content types to keep your feed fresh:

• Product demos (30%): Show your product in action. Use AI Product Video.
• Behind the scenes (20%): Show your process, team, or workspace. Builds trust.
• Educational (30%): Teach something related to your niche. Positions you as an expert.
• Entertainment (20%): Trend participation, humor, relatable content. Boosts reach.

Batch Production Strategy

Creating one video at a time is inefficient. Batch production lets you create a month of content in one day:

1. Monday: Script 12 videos (3 per week for 4 weeks)
2. Tuesday: Generate all visual assets with AI
3. Wednesday: Edit, add captions, export for all platforms
4. Thursday: Schedule posts using Later or Buffer

This workflow produces 48 platform-specific videos (12 scripts x 4 platforms) in 4 days.

Measuring Performance

Track these metrics per platform:

• Watch time: Average percentage of video watched. Target 50%+.
• Engagement rate: Likes, comments, shares divided by views. Target 3%+.
• Click-through rate: Link clicks divided by views. Target 1%+.
• Follower growth: New followers per video. Track trends over time.

Common Mistakes

1. Weak hooks. If the first 2 seconds do not grab attention, nothing else matters.
2. No captions. 85% of social video is watched without sound.
3. Wrong aspect ratio. Horizontal video on TikTok gets ignored. Always match platform specs.
4. Over-production. Social media rewards authenticity over polish.
5. Inconsistent posting. Algorithms reward consistency. Post at least 3x per week per platform.
