Academy › AI Video for Marketers › Lesson 2
Choose your tool by goal
Match your goal to a type of tool, then compare plans and limits before you pay. · 8 min read
There are many AI video tools and they change quickly. Instead of memorizing a ranking, learn to choose by goal and then verify the current details.
What you will build
A shortlist of two tools for one goal, with the facts you need to compare them.
Figure 1. Goal first, then tool type, then compare plans.
Step 1: Match the goal to the type
| Goal | Tool type | Tools we cover |
|---|---|---|
| Cinematic or creative clips | Generative video models | Runway, Luma Dream Machine, Kling AI, Pika, Hailuo AI |
| A presenter or explainer | Avatar video | HeyGen, Synthesia |
| A quick marketing video from a prompt | Prompt-to-video editor | invideo AI |
Our AI video comparison lists plans, free tiers and limits for all eight, with the date each was checked.
Step 2: Compare the same six facts
Copy this table and fill it for each shortlisted tool from the official pricing page:
| Fact | Tool A | Tool B |
|---|---|---|
| Free plan or trial, and its limits | ||
| Cost of the plan you would actually use | ||
| Maximum clip or video length | ||
| Output resolution and watermark rules | ||
| Commercial use terms on that plan | ||
| How credits are counted |
The last two rows decide more projects than quality does. A free plan that watermarks output or restricts commercial use may be fine for testing and wrong for a client.
Step 3: Run the same test brief in both
Use one identical prompt and one identical script. Judge on:
- Does it follow the prompt?
- Is motion natural for the shot?
- How many attempts did you need?
- What did that cost in credits?
Three attempts each is enough to see a pattern.
Step 4: Decide with a rule
Pick the tool with the best result per attempt you could afford, not the best single clip.
Worked example
A freelancer needed 20 short product-teaser clips. Tool A produced one beautiful clip in four tries; Tool B produced acceptable clips in one or two tries. Counting credits per usable clip, B cost far less per finished clip, so B won for the batch while A stayed in the toolbox for hero shots.
Common mistakes
- Choosing from a social media demo reel.
- Ignoring commercial-use and watermark terms until after delivery.
- Paying for a year before running a test brief.
Checklist
- Goal and tool type chosen
- Six facts filled from official pages
- Same brief run in two tools
- Cost per usable clip noted
