Avatar or presentation style.
Do you want an on-screen presenter, voiceover narration, or animated text? Some tools do this better than others.
Voice quality.
Poor text-to-speech ruins an otherwise solid video. Test the voice before committing to a full video.
Editing flexibility.
Can you tweak the output afterwards, or does it lock you into what you generate?
Turnaround time.
Some tools render in minutes. Others take hours. This matters if you're on a deadline.
Brand customisation.
Can you add logos, colour schemes, or custom fonts? Or are you stuck with stock templates?
Pricing model.
Free tiers get you started, but some tools charge per video or per minute of output.
Learning curve.
How long before you can produce something without tutorials?
The Top Options
ElevenLabs What it does well:
ElevenLabs specialises in AI voice synthesis, and it's genuinely impressive. The voices sound natural, with proper inflection and pacing. You can choose from dozens of voices, adjust speaking speed, and add emotion. If your video is voice-first (a script read over slides or existing footage), ElevenLabs will make that voiceover sound professional. Pricing: Free tier gives you 10,000 characters per month. Paid plans start at £6 monthly for 100,000 characters, scaling to £99 for 3 million characters. For most marketing teams, the free tier handles 2-3 short videos monthly. Best for: Teams who already have visuals or slides and just need high-quality voiceover. Also excellent if you're using another tool for video generation but want better audio than its built-in voices. Limitations: ElevenLabs doesn't generate video at all. It's audio-only. You'll need to pair it with another tool if you want talking avatars or animated scenes. The free tier is quite limited if you're producing videos regularly.
HeyGen What it does well:
HeyGen lets you create videos with talking avatars that lip-sync to your script. You can choose from different avatar styles (realistic people, illustrated characters, or even animate your own photos). The avatars look convincing, and the lip-sync is accurate. You can also upload your own avatar or create one from a photo. The video editor lets you add slides, music, and text overlays after generation. Pricing: Free tier includes 3 avatar videos monthly with limited customisation. Paid plans start at £9 monthly for 20 videos and more avatar options. Premium tiers offer custom avatars and API access. Best for: Product demos, training videos, or content where a friendly on-screen presenter adds value. Works particularly well for companies targeting international audiences since you can switch avatars and languages easily. Limitations: Avatar videos can feel artificial if you're not careful with tone. Some users find the avatars slightly unsettling. The free tier is restrictive if you're producing more than a few videos. Video quality caps at 1080p.
Hour One What it does well:
Hour One occupies the middle ground. It combines avatar video with a focus on speed. You paste in your script, choose a virtual presenter, and get a video back quickly. The platform includes built-in slides and templates, so you're not starting from scratch. The presenters look realistic without feeling creepy. It's genuinely fast to use. Pricing: Free tier gives you one video monthly at 480p. Paid plans start at £15 monthly for 10 videos at 1080p, with higher tiers offering more videos and custom branding. Best for: Marketing teams that produce videos frequently and want speed above all else. Hour One is the fastest way from script to video. Limitations: The free tier is extremely limited. You'll need a subscription to produce multiple videos. Customisation options are more restricted than HeyGen. The template library is smaller, though adequate.
Pika AI What it does well:
Pika AI generates video from text prompts and images. Unlike the other tools, Pika doesn't focus on avatars or voiceovers. Instead, you describe what you want to see, and Pika creates animated video. It's excellent for creating B-roll, product shots, or abstract visualisations. The output quality is improving rapidly, and it's genuinely free without restrictive limitations. Pricing: Free tier with monthly credits. Paid plans start at £10 monthly for more credits and faster generation. No hard cap on how many videos you can make; it depends on credit usage. Best for: Creating supporting footage and animations to complement voiceover or avatar videos. Less suitable as a standalone tool for full-script marketing videos, but brilliant for adding visual polish. Limitations: Pika is still developing and doesn't handle complex scenes as reliably as older tools. You can't use it to generate a full video with dialogue and presentation in the way HeyGen or Hour One do. It requires some creative thinking to frame prompts effectively.
Prerequisites
Before you start building your first video, you'll need: - A free account with at least one of the tools listed above (all offer free tiers; start with HeyGen or Hour One if you're undecided)
- A written script or outline of what you want to say (roughly 100-300 words for a 2-3 minute video)
- 15-20 minutes for initial setup and testing
- No coding knowledge required
- Basic familiarity with web browsers and uploading files
- Optional: Pika API key if you want to integrate it with your workflow (free to create, but not essential)
Our Recommendation
The answer depends on what you're producing:
For most marketing teams starting out: Use HeyGen.
It handles script-to-video in one platform. The free tier gets you three test videos monthly, which is enough to learn what works. The avatars look professional enough for LinkedIn and email marketing. Upgrade to the paid tier once you're producing more than three videos monthly.
If you're producing weekly or more: Use Hour One.
It's faster and cheaper at scale. The presenter videos are professional. You'll spend less time fiddling and more time publishing. If voiceover is your priority: Use ElevenLabs for audio, then pair it with a free video creation tool like Canva or CapCut for the visual layer. This gives you the best voice quality at minimal cost, though it requires you to think about visuals separately. If you want to supplement avatar videos with custom footage: Use HeyGen or Hour One for the main presenter, then use Pika AI to generate supporting shots that fit your brand. This combination produces the most polished results.
Getting Started
Here's how to produce your first marketing video using HeyGen: 1.
Sign up and write your script.
Go to heygen.com and create a free account. Write a script for your video (150-250 words works well for a 90-second video). Keep it conversational, not robotic. Test phrases by reading them aloud.
Create a new project.
Click "Create Video" and paste your script into the text box. Select a language and choose your avatar. Start with a realistic avatar for your first video. Watch the preview to check the tone and pacing.
Customise the output.
Add a title slide with your company logo. Choose background music from the library. Adjust speaking speed if needed. Add text overlays highlighting key points.
Add visuals.
Upload product screenshots or company images as background layers behind the avatar. This makes the video less flat and more contextual.
Export and publish.
Download the video at 1080p and upload it to YouTube, LinkedIn, or your website. You now have a professional marketing video created in under an hour without a videographer in sight. Total time from script to finished video: 30-45 minutes.
