Video isn’t just part of the marketing playbook anymore – it is the playbook. From short-form content that drives traffic to polished explainers that turn maybe into yes, video has become the loudest, clearest way to say what your brand is about.
But creating great videos at scale? That’s where most agencies hit a wall. Deadlines pile up, budgets stay tight, and clients expect Hollywood with a Canva budget.
Enter AI-powered video tools. They’re making it easier for marketing agencies to produce videos that look sharp, sound professional, and land with audiences – without needing a camera crew or a three-day shoot.
We’re cutting straight to the good stuff with three tools that are actually worth your time and make a real difference in your workflow.
HeyGen
Let’s start with the one tool that’s on everyone’s radar for a reason. HeyGen isn’t just good – it’s the kind of tool that makes you wonder why you were doing it the old way in the first place.
If you need video content that feels personal, persuasive, and incredibly polished, HeyGen gets it done in a fraction of the time and effort you’d normally expect.
What makes it stand out? For one, its lifelike presenters. This isn’t just some stiff talking head with robot energy. These digital presenters feel human enough to fool you at first glance – and that’s the whole point.
You get natural movement, realistic facial expressions, and voices that don’t sound like they were spit out by a GPS. Add to that a wide selection of languages and tones, and suddenly your agency is producing global-ready content without the headache of casting or studio time.
Here’s where it gets even better. Once you’ve written your script and picked your on-screen talent, everything happens inside an interface that doesn’t require a tutorial.
Seriously, your intern could figure it out in 10 minutes. You upload your copy, drag and drop visual elements, maybe adjust the layout a bit – and then boom, your video is ready to go. There’s no wrestling with clunky software or waiting hours for rendering.
And yes, if you’re wondering where the magic happens, it’s HeyGen.com. Once you try it, it’s hard to go back. The ability to create videos that feel like they came from a live shoot – without ever leaving your desk – is a game changer.
Their AI avatar feature in particular is something you just have to see to believe. It’s not hype. It’s just that good.
Runway
Next up is Runway, and it earns its place here because of one thing: flexibility. Sometimes a client wants a clean, professional training video, and sometimes they want a surreal promo featuring a cat driving a convertible through a neon cityscape. Runway can handle both without flinching.
The platform is built for creative control. You’re not locked into templates or forced into awkward design choices. Instead, you get tools that let you tweak, stretch, remix, and rebuild your video visuals however you want.
Need to remove a background, generate new footage from text, or reimagine an existing clip with a different vibe? You can do all of that, and it won’t feel like you’re building IKEA furniture with missing screws.
Runway is especially good when you’re working with scraps. Maybe your client only gave you vertical iPhone footage of their office tour. You can clean that up, sharpen the visuals, add transitions that look intentional, and drop in text overlays that don’t scream “last-minute.”
And it moves fast. Whether you’re turning a bland testimonial into a dynamic highlight reel or adding voiceovers and sound design without opening another app, the process stays tight.
Even when the content itself is experimental or offbeat – yes, even if your client suddenly decides they want Donald Trump deepfaked into a sales pitch – you’ve got tools that can keep up.
Runway isn’t the flashiest name in the AI video world, but that’s kind of the point. It does the job well, doesn’t make a mess, and keeps your team moving forward instead of fiddling with plugins and patchy exports.
Synthesia
For agencies that handle a lot of business-to-business work or internal communication projects, Synthesia is your quiet workhorse. You’re not making viral TikToks with it – you’re making clean, professional videos that explain processes, introduce products, or train employees.
The kind of stuff that clients expect to be “boring” until you show them a Synthesia version and suddenly, they’re impressed.
This tool isn’t built to dazzle – it’s built to deliver. You pick a presenter from their large lineup of digital humans, drop in your script, select a background or upload your own branding elements, and you’re ready to publish.
It’s all about taking what used to be a clunky PowerPoint or dense PDF and turning it into a video someone might actually watch. And for marketing agencies, that kind of transformation is gold.
Clients love it because it makes their messaging feel sharp and modern. Agencies love it because it saves hours. A
nd let’s be honest, we’ve all had clients who email the dreaded “Can we change just one word in the video?” at 4:45 p.m. With Synthesia, you can just swap the word and re-export. No drama, no reshoots, no editing timeline nightmares.
It’s especially effective for content that needs consistency across languages and markets. Want the same training video in five languages? Done. Synthesia’s multilingual capabilities keep your branding on-point no matter who’s watching.
The Wrap-Up
Marketing agencies have always had to juggle creativity with efficiency. These tools make it a lot easier to do both without having to compromise on quality.
Whether you’re chasing high engagement, working under a tight deadline, or just trying to make video less of a time-suck, these three platforms will get you there – fast, polished, and without the usual stress.
