From this input to this video

A script based on NIST’s published guidance becomes a whiteboard training video with captions.

Prompt

Create a 45-second animated cybersecurity training video that teaches recognizing and reporting phishing using NIST’s small-business guidance at https://www.nist.gov/itl/smallbusinesscyber/guidance-topic/phishing to small-business employees. Use my script verbatim for the voiceover — do not rewrite it: An urgent message can make a risky click feel necessary. Phishing impersonates a trusted sender to steal information or deliver harmful software. Pause when a message asks for a password, a payment, a download or immediate action. Check the sender, and verify the request through a contact method you already trust. Do not use the message’s own link or phone number to verify it. Report suspicious messages using your organization’s process. If you already clicked, tell your security contact promptly. Pause, verify and report. Read NIST’s phishing guidance and learn your team’s reporting process. Explain the idea with the warning signs and verification steps in the NIST guidance and reinforce each key term with clear on-screen labels. Visual style: whiteboard. Tone: calm and practical. Open with a short real-world hook, walk through the concept step by step, then close on a one-line recap and this call to action: Read NIST’s phishing guidance and learn your team’s reporting process. Add captions for muted playback.

ngram vs HeyGen, answered

When should I consider ngram as a HeyGen alternative?

Try ngram when your recurring job starts with approved source material: a lesson, product update, deck or recording. The example on this page shows a short training video with its actual script. Adapt that brief and judge whether the result fits your audience.

Is HeyGen limited to talking-head videos?

No. Video Agent supports uploaded media, planning and chat revisions, while HyperFrames adds custom motion graphics. HeyGen also offers avatar and translation workflows. Compare the specific process you need rather than treating it as an avatar-only tool.

Do both products let me review a plan?

Yes. ngram asks you to approve the plan containing the script. HeyGen Video Agent’s Chat Mode lets you refine its plan before proceeding; its Autopilot mode follows a different path.

Can I bring a HeyGen video into ngram?

Export the footage you want to reuse, then upload the video file to ngram. Add the new audience, purpose and supporting source material. Review the proposed plan. Keep your original editable HeyGen project for changes to that original.

Can I create a presenter video in ngram?

Yes. Choose a compatible generation model and presenter in the composer. For an interview or Q&A, ask for a conversation and describe the speakers and their roles. Review the proposed dialogue before generation. If a particular likeness or delivery matters, evaluate the output before expanding it into a series.

How do I apply my branding?

Set up your Brand Kit and select it in the composer for this video. Create and edit reusable intro/outro slide designs in the kit, then choose the saved slides you want to include. Select your style and enable captions when wanted.

How do I use a lesson in my learning platform?

On a paid ngram plan, download the finished MP4 and add it to your learning platform. HeyGen Business lists SCORM export and LMS integrations for teams that need those course-delivery features.

How does pricing compare?

ngram: Free: 1,000 credits/month. Basic: $29/month on monthly billing. HeyGen: Creator $29/month with 600 credits; Pro from $49/month with 1,000 credits. Monthly web billing.

Can I use either product through an AI assistant?

Both offer MCP and API connections. Check each product’s supported actions and account billing for the workflow you want to automate. ngram creation requires enough credits for the requested video.
