Day 13 – Video and Audio AI Lesson

Lesson Overview

This lesson surveys the most useful video and audio AI apps so you can turn ideas into production assets quickly. You will see two leading text to video options, Runway and Luma Labs Dream Machine. Runway’s Gen-3 model creates high motion clips from text or an image prompt. It is paid only and geared toward quality results for practical use. Gen-2 is steadier with more control and subtler motion, which can be preferable for certain shots. Dream Machine has surged in popularity because it currently offers a free tier. Quality varies by prompt, but it is excellent for testing ideas and learning prompt styles that reference camera angles and cinematography terms. OpenAI’s Sora is also mentioned as a future option to watch.

You will also see how AI avatars in HeyGen can deliver clear, repeatable explainers, training videos, and simple ads. HeyGen is paid and template driven, and supports both stock avatars and self-cloning for a consistent presenter. For voice work, the lesson covers a leading AI voice generator that handles text to speech, speech to speech, dubbing, multilingual output, and voice cloning with a large voice library. Finally, you will use Sono to produce original music from text prompts and built-in templates, which is ideal for background tracks and quick mood cues.

This lesson is practical for marketers, educators, product teams, and solo creators who want reliable, repeatable results without hiring full production crews for every small deliverable.

Who This Is For

If you need reusable video and audio assets without heavy production overhead, this lesson will help you spot the right tool fast.

• Marketers producing short ads, social promos, and motion cutaways
• Educators and L&D teams building explainers and training modules
• Founders and product teams needing quick launch videos or feature updates
• Content creators who want on-camera alternatives and faster iterations
• Agencies and freelancers delivering short-form content on tight timelines

Where This Fits in a Workflow

Use these tools when you have a script, concept, or storyboard and you need short visuals, a presenter, a voiceover, or music to complete a draft. For example, you might create a still image in an earlier step, then use that image as a prompt in Runway or Dream Machine to produce a 5 to 10 second motion clip that anchors a social ad. If you need a presenter but do not want to record, drop your script into a HeyGen template and select an avatar for consistent delivery. Add narration from the AI voice generator to test tone options. Finish with a 20 to 30 second track from Sono to match the mood. These pieces slot into editors like Premiere, CapCut, or any online video builder so you can assemble and test quickly before committing to a budget.

Technical & Workflow Benefits

The old way meant sourcing stock footage, hiring videographers, booking talent, and licensing music, even for simple tests. Iteration was slow and costly. With the approach in this lesson, you can draft motion clips from a single text or image prompt, audition multiple voices in minutes, and generate original music on demand. That means you can validate concepts before a full shoot and only invest when an idea proves itself.

Two common gains stand out. First, ad testing improves because you can spin up several 5 to 10 second variations with different camera styles or subjects and learn what performs. Second, training content becomes more consistent. A templated HeyGen avatar plus a cloned or selected voice keeps tone and pacing uniform across modules, even when scripts change late. The time savings are substantial, and the quality is now good enough for many real uses when prompts are clear and specific.

Practice Exercise

Try a mini production sprint that covers video, voice, and music.

Scenario: You need a short product teaser for social. Your hero visual is a still image you created earlier.

Steps:

1. Generate a 5 to 10 second motion clip from that image using Runway Gen-3 or Dream Machine. If you use text only, include a camera angle and movement, such as low angle shot or slow dolly out for clarity.
2. Write a one sentence hook and produce a voiceover with the AI voice generator. Test two voices with different delivery styles.
3. In Sono, create a 20 to 30 second background track that matches your intended mood. Pick a style template if you are unsure where to start.

Reflect: Which combination of prompt wording, voice, and music produced the most believable result for your use case, and what would you change before paying for more generations?

Course Context Recap

This lesson builds on your earlier prompting and image creation skills by extending them to moving visuals, narrated audio, and music. You will see where image prompts shine, how text prompts benefit from cinematography terms, and when to use avatars or synthetic voices to speed up delivery. Next, you will continue applying these production skills as you round out the boot camp and prepare to assemble assets into complete, shareable content. Keep going to explore the full course and turn these quick tests into finished outputs that support your goals.
