| Connected workflows | REST, CLI and MCP; API pricing separate | Documented talking-avatar API; separate usage terms |
HeyGen: Create, revise and translate with Video Agent
HeyGen Video Agent accepts uploaded documents, images and video. Chat Mode offers plan review; Autopilot is a different creation path. You can revise through chat or edit a copy in AI Studio. It is broader than a presenter reading text.
Its July release describes HyperFrames motion graphics and website/Figma-based workflows. Avatar and translation features remain useful reasons to evaluate HeyGen, but source-based creation and planning are no longer distinctions that belong only to another tool.
Current pricing includes Brand Kit on Creator and Pro, with SCORM/LMS and interactive features listed on Business. Its developer platform covers REST, CLI and MCP operations; API pricing is separate from the web subscription.
LiveAvatar is HeyGen’s separate platform for real-time interaction, with its own credits and models. A Creator video plan is not a LiveAvatar allowance, and the avatar assets are not automatically cross-compatible. The current setup guide says Starter stopped accepting new customers on September 25, 2026; use its current plans for a new deployment.
Vidnoz: Generate from documents and refine the scenes
Vidnoz AI Video Wizard accepts prompts, scripts, PowerPoint, PDF and other documents. Choose duration, tone and aspect ratio, then edit narration, avatars, text, music and visuals. A completed script is one possible input rather than a prerequisite for every video.
Its online editor supports uploaded footage and recordings with crop, trim, speed and media controls. Real product footage can be part of the finished video. Compare those controls with the actual revisions your team makes.
Starter lists 1080p, watermark removal and SCORM. Business adds Brand Kit, voice cloning, translation, branded video pages, collaboration and SSO. Vidnoz Gen, Voice and Video Translator have separate plan pages; a price for one product is not necessarily the entitlement for another.
Compare the lesson you need to maintain
For a customer-facing update, provide the real document and authorized footage, then require a changed instruction and shorter ending. HeyGen supports plan review in Chat Mode and editing a copy in AI Studio; Vidnoz exposes narration, avatar, media and format controls after the AI Wizard draft.
For learning delivery, HeyGen lists SCORM/LMS features on Business while Vidnoz lists SCORM on Starter. For translation, check the actual language and product allowance: Vidnoz Video Translator has a separate pricing page. Public documentation does not establish a universal quality winner for your script.
For a presenter-led version, compare the voice and delivery using the same script and target language. Product documentation establishes features and plan access; it does not establish which avatar your audience will find most convincing.
Pricing and recurring usage
| Plan | Billing checked | Scope |
|---|---|---|
| HeyGen Creator | $29/month | 600 monthly credits; videos up to 30 minutes; 1080p |
| HeyGen Pro, entry allowance | $49/month | 1,000 monthly credits; 4K |
| HeyGen Business | $149/month; additional seats $20/month | 1,500 shared credits; learning and collaboration features |

HeyGen Free allows three videos/month of up to one minute. Monthly unused web credits roll over one additional cycle; annual credits follow the annual renewal terms. Model and operation determine usage, so use the current generation estimate rather than a single per-minute conversion. API allowance and pricing are separate.
Other credit quantities are selectable. Standard generation is listed at 0.5 credits/second, while expressive and product avatars cost 2 credits/second. Other operations use credits separately and unused credits do not roll over. Free lists watermarked 720p exports; inspect the current account allowance rather than assuming an old daily-credit figure.
ngram pricing includes 1,000 credits/month on Free. Basic costs $29/month with monthly billing and includes 3,000 credits per cycle; annual billing is $23.20/month equivalent with 36,000 credits supplied upfront. The base rate for premium AI video generation is 10 credits per second, with a cheaper model at 3. Share publicly or embed on Free; use a paid plan for MP4 downloads and Basic or above for unlisted links.
Watch a real script become a training video
The ngram example uses a script based on public NIST phishing guidance and a whiteboard treatment. Inspect its exact input, settings, transcript and result, then adapt the brief for your own lesson. It demonstrates ngram creation from a script; it is not an imported HeyGen or Vidnoz project or a test of their output.
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.

Video generation uses credits. Review your estimate in ngram. MP4 downloads require Basic or higher.
How credits workBring your approved material into ngram
Start with a script, public page, uploaded PDF or PowerPoint. For existing footage, use the source tool’s download controls and your account’s export permissions to save an authorized MP4, then upload it with a brief for the new audience. Keep the original editable project and interactive course in their authoring tool.
Choose the style, aspect ratio and duration. Select your configured Brand Kit in the composer and enable captions when wanted. Approve the plan containing the script, then request revisions or use the timeline. Download the finished MP4 on a paid plan and add it to your learning platform.
After updating the original policy or document, tell ngram what changed and ask it to revise the lesson. For a different format, choose the new duration or aspect ratio and request another version. Review each result before replacing the published video.

Frequently asked questions
Which is cheaper for the same video?
The selected Vidnoz Starter allowance costs $26.99 monthly and HeyGen Creator costs $29 monthly, but the credit units and models differ. Compare the same intended scenes, revisions, export and billing period rather than treating the two balances as equivalent.
Can I reuse an exported video in ngram?
Yes. Upload an authorized MP4 as source footage and describe the new audience and lesson. Keep the original editable project separately; exporting footage does not transfer its scene structure, quiz logic or review history.
Does the example compare avatar quality?
No. It is a real whiteboard lesson made in ngram from a NIST-based script. The exact prompt and result help you judge that workflow. To compare presenters, evaluate the actual script, voice and language you need in each product.
Can I share the ngram result on Free?
Free includes 1,000 credits per month and supports public sharing and website embeds. Use a paid plan for MP4 downloads; unlisted links start with Basic.
How should I choose for a learning platform?
Check whether the deliverable is a video file, a streaming course or a self-contained course package. Verify the required plan, tracking and update process with your platform. For ngram, download the MP4 on a paid plan and add it to the learning platform.
