A client called me eighteen months ago in a mild panic. Their competitor had just dropped a polished product video -- spokesperson, B-roll, branded lower thirds, the works -- and my client was convinced they'd hired a production company. The competitor was a two-person startup with no production budget.
They'd figured out the AI video workflow.
My agency spent the next three months reverse-engineering it, testing every tool, and building out a production process we now use for clients at every budget level. This guide is that process, documented.
It's not a toy workflow for making cute demo clips. It's how you produce marketing videos that convert -- product demos, explainer videos, spokesperson content, social ads -- without a production team, a studio, or a five-figure production budget.
The Full Workflow at a Glance
Step 1: Script → ChatGPT or Claude
Step 2: Visual generation → Runway, Pika, or Kling (depending on budget and style)
Step 3: Voiceover → ElevenLabs or Murf
Step 4: Spokesperson video → Synthesia or HeyGen (if you need on-camera talent)
Step 5: Editing → Descript
Step 6: Publish → native to platform (YouTube, Meta, LinkedIn, etc.)
Each step has tool recommendations at three budget tiers. Let's go through them.
Step 1: Script Writing
The script is everything. A bad script with great visuals is still a bad video. A great script with mediocre visuals can still convert.
I use Claude for long-form scripts and video copy because it handles nuance and tone better than most alternatives for writing tasks. ChatGPT is a solid option too -- it's better at following precise formatting instructions, which matters when you're generating scripts that need to fit a specific duration.
What to put in your prompt:
- The video's goal (awareness, conversion, product education)
- Target audience (specific, not generic: "mid-market SaaS buyers, VP-level, evaluating vendor software" not "business professionals")
- Desired length (give AI a word count: 150 words ≈ 60 seconds of voiceover)
- Tone (conversational, authoritative, warm, urgent)
- Any required messaging points or disclaimers
The output won't be perfect. It'll be 70-80% there. You edit the rest. The AI handles the scaffolding; your judgment handles the finishing.
Budget tier:
- Free: ChatGPT free, Claude free
- Indie: ChatGPT Plus or Claude Pro at $20/month (you probably already have this)
- Pro: No additional tooling needed at this step -- the $20/month AI subscription covers it
Step 2: Visual Content Generation
This is where the budget and quality trade-offs are most significant. The right tool here depends entirely on what kind of visuals you need.
For atmospheric B-roll, product shots, and cinematic content:
Runway Gen-3 is the quality leader. Text-to-video and image-to-video generation at a quality level that holds up in 30-second product ads. I've produced B-roll for Facebook video ads in Runway that outperformed stock footage in A/B tests -- not because it was higher quality, but because it was uniquely tailored to the product's visual identity.
Kling is the value alternative. If Runway's credit limits are constraining your output, Kling's motion quality is close enough for most marketing applications at a substantially lower price.
For social-first content (Reels, TikTok, Shorts):
Pika is faster, cheaper, and better optimized for short-form. The style controls are intuitive, the free tier is real, and the content reads as native to social platforms in a way that over-produced video sometimes doesn't.
For spokesperson or on-camera talent videos:
This is where things get interesting. If your video needs a person on camera -- explaining a product, presenting to the viewer, delivering a testimonial -- you have two main paths.
HeyGen lets you create a digital avatar from a 30-second video of a real person (yourself, a team member, or a professional) and then generate as many avatar videos as you need from scripts. The lip sync and natural expression quality is genuinely impressive in 2026. For multilingual content -- same video, 20 languages -- HeyGen is transformative.
Synthesia offers similar avatar capabilities with stronger enterprise workflow features (team approvals, LMS integrations, bulk generation). Better for larger L&D or corporate communication needs; HeyGen is better for marketing use.
Budget tiers:
- Free: Pika free tier (limited generations), Runway free trial
- Indie ($20-50/month): Pika Basic ($8/month) + either Kling Standard (~$8/month) or Runway Standard ($12/month). HeyGen Creator ($29/month) if you need spokesperson content.
- Pro ($100+/month): Runway Pro ($28/month) + HeyGen Business ($89/month) for full production capability
Step 3: AI Voiceover
This step transformed faster than any other part of the AI video stack in the past 18 months.
ElevenLabs is the quality leader, full stop. The voice realism on their premium voices is at a level where, in audio-only tests, listeners regularly can't identify the output as AI-generated. For marketing content where voiceover quality directly impacts brand perception, ElevenLabs is worth the investment.
What I use it for: product explainer voiceovers, ad narration, brand intro/outro audio. The voice cloning feature (clone your own voice or a team member's) is genuinely useful for brand consistency -- once you've trained a voice, every piece of content has a consistent narrator.
Murf is the team-focused alternative. Where ElevenLabs is optimized for individual output quality, Murf is built for teams -- it has better collaboration features, brand voice management across team members, and a review/approval workflow that matters when multiple people are touching content. The voice quality is slightly below ElevenLabs but not dramatically so.
For solo creators and small teams: ElevenLabs. For marketing teams with multiple content producers who need voice consistency managed at the system level: Murf is worth the evaluation.
For a deeper look at the AI voice landscape -- including voice cloning, language support, and pricing across six tools -- see our Best AI Voice Generators 2026 roundup and the full ElevenLabs Review 2026.
What to send to your voiceover tool:
- The finalized script (post-editing -- don't generate voiceover from a first draft)
- Character/tone notes (how to deliver certain phrases, pacing preferences)
- Note any brand terminology that might get mispronounced -- you'll need to use phonetic spelling or the pronunciation tool
Budget tiers:
- Free: ElevenLabs free tier (10,000 characters/month -- enough for several short videos)
- Indie ($5-22/month): ElevenLabs Starter ($5/month) covers most small content operations
- Pro ($99/month+): ElevenLabs Creator or Pro for high-volume production, Murf for team workflows
Step 4: Editing -- Where It All Comes Together
I've used most professional video editors. Premiere, Final Cut, DaVinci Resolve, CapCut. For AI-generated marketing video specifically, Descript has become my default, and I recommend it strongly for marketers who aren't video production specialists.
Here's why: Descript is script-first. You paste in your voiceover script (or record directly), and Descript creates a transcript. From there, you edit the video by editing the text -- delete a sentence from the script, the corresponding audio and video clip is cut. It's the most intuitive video editing interface for anyone who thinks in words rather than timelines.
Specific features that matter for AI video production:
- Underlord AI editing -- identify filler words, awkward pauses, and poor takes with one click
- Scene detection -- automatically detect scene changes in B-roll footage and create cut points
- Stock integration -- pull stock footage, images, and audio directly within the editor
- Studio Sound -- audio cleanup that turns mediocre voiceover recordings into something usable
For editors who want full timeline control, Premiere or Final Cut is still more powerful. But for marketers who need to produce polished video without becoming a video editor, Descript's learning curve is dramatically shorter.
Budget tiers:
- Free: Descript free tier (limited transcription hours but functional for single videos)
- Indie ($24/month): Descript Creator -- removes limitations that constrain production at scale
- Pro ($40/month): Descript Pro -- unlocks higher quality exports, more transcription, team features
Putting It Together: Three Budget Stacks
Free Tier Stack ($0/month)
- Script: Claude free or ChatGPT free
- Visuals: Pika free tier
- Voiceover: ElevenLabs free tier
- Editing: Descript free + CapCut (free)
What you can produce: 2-4 short social videos per month (30-60 seconds). Quality will show the limitations of free tier generation, but it's genuinely functional for testing the workflow and producing simple product or announcement content.
Indie Stack ($20-50/month)
- Script: Claude Pro or ChatGPT Plus ($20/month -- you probably already have this)
- Visuals: Pika Basic ($8/month) + Kling Standard (~$8/month)
- Voiceover: ElevenLabs Starter ($5/month)
- Editing: Descript Creator ($24/month)
Total: ~$45/month (excluding the AI subscription you already have)
What you can produce: 10-20 social videos per month, 2-4 longer product explainers. Good enough quality to run as organic social content and low-budget paid social. This is the stack I recommend for small businesses and solo creators who are serious about video content.
Pro Stack ($100+/month)
- Script: Claude Pro or ChatGPT Plus ($20/month)
- Visuals: Runway Pro ($28/month) + HeyGen Creator or Business ($29-89/month)
- Voiceover: ElevenLabs Creator ($22/month) or Murf Business ($99/month for teams)
- Editing: Descript Pro ($40/month)
Total: ~$140-280/month depending on tier choices
What you can produce: High-quality cinematic B-roll, professional spokesperson content, multilingual versioning, 40+ pieces of video content per month. This is a production operation, not a hobbyist workflow. It competes with agencies charging $3,000-8,000/month for comparable output.
Tips From Actual Production Runs
A few things that aren't obvious from tool demos:
Build a prompt library. The prompts that work for your brand's visual style -- the lighting, the aesthetic, the scene types -- are an asset. Document them. When you find a Runway prompt that produces exactly the B-roll tone you want, save it. Rebuilding that from scratch every time is wasteful.
Generate 3-5x what you need. AI video tools produce inconsistent results. If you need 6 clips for a video, generate 20-30 and pick the best 6. Budget your credits and subscriptions accordingly.
Match audio to visual pacing, not the other way around. It's tempting to generate video first and then find audio to match. Do it the opposite way -- produce the voiceover, get the pacing right, then generate B-roll to match the audio beats. The video will feel more cohesive.
Use real B-roll alongside AI B-roll. Nobody says it's all-or-nothing. Mix AI-generated establishing shots with real product footage you shoot on your phone. The combination often works better than pure AI video for product-specific content.

The bottom line: you don't need a production team. You need a workflow and the patience to learn these tools. The production team cost was always mostly workflow management and technical execution -- and AI is now handling both.
