Start with the information-transfer task rather than a preferred production format. Define what the audience must understand, feel, or do, then compare text, voice, and video according to clarity, speed of consumption, context requirements, and production constraints. Voice may make creation and dictation efficient while remaining slow for scanning. Text can be searched and skimmed, while video can demonstrate movement, emotion, or spatial relationships quickly. Choose the modality that communicates the specific message most clearly and efficiently, or combine formats when each serves a different part of the task. AI lowers the historical cost gap between text and richer media, making this decision practical at scale. Performance data should then confirm whether the selected format actually improved comprehension or action.

Extracted from Marketing Against The Grain during Kip's discussion of how AI will rebalance text, voice, and video on the internet.
Core principles
- 01Format should follow the communication task
- 02Creation efficiency and consumption efficiency are different
- 03Text, voice, and video have different strengths
- 04Use the clearest and fastest format for the audience
- 05Lower production costs permit a better balance of modalities
How to run it
- 1
Define the transfer task
State what the audience needs to receive and the action or understanding that should result.
Pro tip Frame the requirement from the audience's perspective rather than the creator's convenience.
Watch out A vague objective makes every format appear equally suitable.
- 2
Assess information shape
Determine whether the message is best scanned, heard, demonstrated, visualized, or emotionally performed.
Pro tip Break complex assets into components if different information types need different formats.
Watch out Do not assume one modality must carry the entire experience.
- 3
Compare clarity
Evaluate which available format minimizes ambiguity and unnecessary explanation.
Pro tip Use video for demonstrations and text for dense material that benefits from scanning or reference.
Watch out Production novelty is not evidence of communication clarity.
- 4
Compare consumption speed
Estimate how quickly the audience can extract the needed value from each format.
Pro tip Include controls such as captions, transcripts, chapters, or playback speed where appropriate.
Watch out A format that is fast to create may still be slow to consume.
- 5
Choose and produce
Select the best format or combination, then use human direction and AI assistance to create it efficiently.
Pro tip Repurpose the same source material only when each adaptation fits its modality.
Watch out Avoid automatic format conversion without editorial review.
- 6
Validate the decision
Measure comprehension, completion, engagement, and action to determine whether the format served the task.
Pro tip Compare formats on the same audience and objective where possible.
Watch out Do not infer comprehension solely from view counts.
In the wild
A company uses a short video to demonstrate where settings are located, a concise voiceover to explain the rationale, and a searchable text checklist for implementation. Each modality handles the part it communicates fastest.
→ Customers understand the process quickly and retain a reference they can revisit during setup.
Common mistakes
Defaulting to text
Text may be familiar and inexpensive, but it can be inefficient for visual demonstrations or emotional communication.
Optimizing only for creation
A creator-friendly medium can impose unnecessary time or cognitive load on the audience.
Using video for everything
The growth of AI video does not eliminate the scanning, search, and reference advantages of text.
Is it for you?
Best for
It is best for marketers deciding how to present education, demonstrations, instructions, or persuasive content.
Not ideal for
It is not ideal when accessibility, bandwidth, compliance, or platform constraints dictate the format in advance.
From the transcript
“And I think what the internet's gonna move to is you are going to be in the perfect modality to get the information as clearly…”
“Right. Whether that's text, whether that's voice, whether that's video, what have you, right?”
“And because that before voice and video were so much more expensive than text, we just use text for most things.”
