TL;DR: You do not need a production team to publish scroll-stopping social videos. This guide walks through the exact workflow: pick your tool, write a prompt, generate or edit, add captions, and publish. We cover CapCut, InVideo AI, OpusClip, Canva, Synthesia, and Avocado AI with honest trade-offs for each.
Every AI social media video maker follows the same core loop. The tools differ in which steps they automate and how much control you keep.
Choose your tool based on content type (generative, editing, clipping, or avatar)
Write a prompt or upload source material (a long video, product images, or a script)
Generate or edit the video clip
Add captions, music, and branding
Export in the right aspect ratio and publish
Here is how each step works in practice, with tool-specific notes.
Step 1: Choose Your Tool Based on Content Type
Not every AI video tool does the same thing. The first decision is matching the tool to your content format.
If you need generative video from a text prompt:
Tools like InVideo AI and Avocado AI generate video clips directly from text descriptions. You describe a scene, the AI produces footage. InVideo AI starts at $17/month with access to models like Sora 2 and Veo 3.1. Avocado AI starts at EUR 19.99/month and includes Seedance 2.0, Hailuo Pro, and Kling 3.0 in a single credit pool.
If you need to edit existing footage with AI assistance:
CapCut is the dominant editing-first tool. The free plan includes auto-captions, filters, and a multi-track timeline. Pro at $9.99/month adds AI video generation from text prompts, 4K export, and 1TB cloud storage. CapCut is owned by ByteDance (TikTok's parent company), so its template library is heavily optimized for short-form vertical content.
If you need to clip long-form video into shorts:
OpusClip takes a long video (podcast, webinar, YouTube video) and automatically identifies the most engaging moments, cuts them into vertical clips, adds captions, and scores each clip for virality potential. Free plan gives 60 processing minutes per month with watermarked exports. Pro at $29/month removes watermarks and adds social scheduling.
If you need design-first video with templates:
Canva is not a dedicated video tool, but its drag-and-drop editor handles simple social videos well. Pro at $12/month (billed annually) includes 141M+ premium assets and AI features like background removal. Best for teams already using Canva for graphics who want to add short video clips to their workflow.
If you need AI avatar or spokesperson videos:
Synthesia generates videos where an AI avatar speaks your script. Starter at $29/month gives 10 minutes of video per month with 125+ stock avatars. Creator at $89/month expands to 30 minutes and 180+ avatars. Best for corporate training, product explainers, and multilingual content (140+ languages).
Step 2: Write Your Prompt or Upload Source Material
The quality of your output depends heavily on the input. Here is what works for each workflow.
For generative video (InVideo AI, Avocado AI):
Write a specific scene description. "A woman unboxing a skincare product on a marble countertop, natural window light, close-up shot" produces better results than "product unboxing video." Include the mood, lighting, camera angle, and subject details.
For editing workflows (CapCut):
Upload your raw footage. CapCut's AI tools work on existing material: auto-captions analyze speech, smart reframing tracks subjects when switching aspect ratios, and AI clipper identifies highlight moments.
For clipping workflows (OpusClip):
Upload a long video or paste a YouTube URL. OpusClip's AI analyzes the transcript, visual content, and audio cues to find the best 30-60 second segments. You can specify topics via natural language prompt on the Pro plan.
For avatar videos (Synthesia):
Write a script. The AI avatar will speak exactly what you write. Keep sentences short and conversational. Avoid jargon unless your audience expects it.
Step 3: Generate or Edit the Video
This is where the tools diverge most.
CapCut gives you a full timeline editor. The AI features (auto-captions, smart reframing, AI clipper) speed up manual editing tasks. You still have granular control over every cut, transition, and effect. The learning curve is low compared to Premiere Pro or DaVinci Resolve.
InVideo AI generates a complete video from your prompt, including stock footage, voiceover, music, and captions. You can refine by reprompting ("make it faster," "change the voice to British male," "add more product close-ups"). The output is ready to publish with minimal editing.
OpusClip is mostly automated. Upload, wait for processing, review the clips. The AI does the cutting, captioning, and reframing. You can trim clips or adjust captions on the Pro plan, but the workflow is designed to minimize manual editing.
Avocado AI works as a Workspace where you pick from multiple video models. Seedance 2.0 handles general-purpose generation at 19 credits per 5-second clip. Hailuo Pro is cheaper at 7 credits per 6-second clip. You can also build multi-step workflows in Flows to chain image generation, video generation, and audio together.
Synthesia generates the video from your script automatically. You pick an avatar, background, and language. The AI renders the video in minutes. Editing means changing the script and regenerating.
Step 4: Add Captions, Music, and Branding
Captions are non-negotiable for social video. Most viewers watch without sound.
Auto-caption tools by platform:
CapCut: Auto-captions with animated styles, keyword highlighting, and multi-language support. Included on the free plan.
OpusClip: AI captions with emoji and keyword highlights. Animated templates on all paid plans.
InVideo AI: Captions are generated as part of the video creation process.
Canva: Basic text overlays. No auto-caption from speech.
Synthesia: Captions are baked into the avatar video output.
Music:
CapCut includes a royalty-free music library on Pro. InVideo AI adds background music automatically. Avocado AI has a dedicated Music/Audio Studio for generating custom tracks with AI. For OpusClip and Synthesia, you add music separately or use what the tool provides.
Branding:
CapCut Pro and OpusClip Pro both support brand templates (logos, colors, fonts). Canva's brand kit is the strongest option if brand consistency across formats matters. Synthesia Creator adds branded video pages.
Step 5: Export and Publish
Export settings matter for each platform:

Direct publishing:
OpusClip Pro includes a social scheduler that posts directly to YouTube Shorts, TikTok, Instagram, LinkedIn, Facebook, and X. CapCut can export directly to TikTok. InVideo AI supports direct publishing to multiple platforms.
Manual publishing:
Export the MP4 and upload natively to each platform. This gives you the most control over captions, hashtags, and posting time.

What Actually Matters When Picking a Tool
Content type drives the decision. If you shoot your own footage and need editing help, CapCut is the clear winner. If you need to generate video from scratch without a camera, InVideo AI or Avocado AI are the right category. If you have long-form content to repurpose, OpusClip is purpose-built for that.
Volume changes the math. CapCut's free plan handles casual use. OpusClip's free 60 minutes/month covers one long video. For daily social posting, you need a paid plan on any tool. InVideo AI's Plus plan at $17/month with 75 credits is the cheapest generative option for moderate volume.
Model access matters for generative video. Not all tools give you the same AI models. InVideo AI includes Sora 2, Veo 3.1, and Kling 3 starting on the Plus plan. Avocado AI includes Seedance 2.0, Hailuo Pro, Sora 2, Veo 3.1, and Kling 3.0 across its tiers. If you want to experiment with different video models in one place, a multi-model workspace beats single-model tools.
Captions are table stakes. Every tool on this list either includes auto-captions or integrates with a captioning workflow. If a tool does not handle captions, skip it.
Aspect ratio flexibility varies. OpusClip Free only exports 9:16. CapCut handles all ratios. Canva handles all ratios. Check the export options before committing if you post across multiple platforms.
FAQ
Can I make social media videos with AI for free?
Yes, with limitations. CapCut's free plan includes full editing tools, auto-captions, and 1080p export without a watermark. OpusClip's free plan gives 60 processing minutes per month but adds a watermark. InVideo AI has a free plan with 2 AI minutes per week and watermarked exports. Synthesia's free plan allows 3 minutes of video per month with a watermark.
What is the best AI tool for TikTok videos?
CapCut is the most popular choice for TikTok because it is owned by ByteDance (TikTok's parent company) and its template library is optimized for TikTok trends. The free plan covers most needs. For AI-generated TikTok content without filming, InVideo AI or Avocado AI generate vertical video from text prompts.
How long does it take to make an AI social video?
With generative tools like InVideo AI or Avocado AI, a 30-60 second clip takes 2-5 minutes from prompt to export. With editing tools like CapCut, a polished 60-second video takes 15-30 minutes depending on complexity. OpusClip processes a 60-minute video into clips in about 10-15 minutes.
Can AI replace a video editor for social media?
For short-form social content (TikTok, Reels, Shorts), AI tools handle 80-90% of the workflow. Auto-captions, smart reframing, and AI clip selection replace tasks that used to take hours. For long-form or narrative content, human editing is still necessary for pacing, storytelling, and creative direction.
