AI Image & Video Generators: What to Use for Each Kind of Visual
Choose by output, not by hype. Midjourney for the best-looking stills, DALL·E 3 inside ChatGPT when you want to describe an edit in plain language, Runway for generated and edited video, Synthesia for presenter-style corporate video, OpusClip to cut long video into short-form clips, and Filmora when you still need a normal editor with AI helpers.
How to choose — five questions worth answering first
- Still image or moving image? These are different markets with different winners — do not expect one subscription to cover both well.
- Do you need a consistent character or product? Consistency across a set is the hardest problem in AI visuals and the main reason projects fail.
- Commercial licensing. Check what the plan actually permits for client work, resale and advertising before you deliver anything.
- Text inside the image. Thai text rendering is still unreliable everywhere — plan to add type in Canva or Figma afterwards.
- How much editing comes after? Generation is 40% of the job. Budget time for upscaling, retouching and layout.
AI image and video generators compared
| Tool | Best for | Real strengths | Limitations to know | Thai language |
|---|---|---|---|---|
| Midjourney | Highest-quality stills, art direction | Best aesthetic quality in the category, strong style control, reference images for consistency | Subscription only, no free tier, and prompting takes practice to control | Prompt in English for best results; do not expect usable Thai text in images |
| DALL·E 3 (in ChatGPT) | Fast iteration and conversational edits | You can describe changes in normal sentences; comes with your ChatGPT plan; follows long prompts well | Lower ceiling on artistic quality than Midjourney; stricter content filters | Understands Thai prompts, but Thai text rendered in images is unreliable |
| Runway | Generated video, VFX and clean-up | Text-to-video, video-to-video, background removal, frame interpolation in one place | Credits burn quickly; long, coherent shots remain hard | Interface is English; prompting in English is safer |
| Synthesia | Corporate training and explainer video | AI presenters plus multi-language voice-over from a script — no camera, no studio | Presenter-led format looks corporate and is easy to spot; per-seat pricing | Supports Thai voice-over; check pronunciation of names and brands |
| OpusClip | Turning long video into short-form clips | Automatically finds strong moments, reframes vertically and adds captions | Its choice of highlights needs human review; caption accuracy varies | Thai captions need proofreading before publishing |
| Filmora | Creators who still need a real editor | Familiar timeline editing with AI extras layered on; one-off licence available | AI features are helpers, not generators — not a Runway replacement | Full Thai interface available |
Our shortlist
- Client-facing stills — Midjourney, finished in Photoshop, Canva or Figma.
- Speed and iteration — DALL·E 3 in ChatGPT — the conversational editing loop is genuinely faster.
- Short-form video at volume — OpusClip on top of one long recording per week.
- Training and internal comms — Synthesia — it removes the studio from the equation.
Turning this into income
- Sell image sets. Product mock-ups, lifestyle scenes, thumbnails and social packs are the easiest first product to sell.
- Offer a short-form video retainer. One long video per week becomes twelve clips — clients value the volume more than the polish.
- Build brand visual kits. A reusable style plus a prompt library is a deliverable you can charge properly for and maintain monthly.
- Produce training video for companies. Script plus AI presenter plus Thai voice-over undercuts traditional production dramatically.
Frequently asked questions
Can I use AI-generated images commercially?
It depends on the tool and your plan, and the rules change. Paid Midjourney and DALL·E plans generally allow commercial use, but read the current terms yourself, avoid prompting for living artists’ styles or trademarked characters, and be careful with recognisable faces and logos.
Why does Thai text come out wrong in images?
Image models generate letter shapes as visual patterns rather than typesetting real text, and Thai’s stacked vowels and tone marks make this much harder than Latin script. The reliable workflow is to generate the image without text and add Thai type afterwards in a design tool.
How do I keep the same character across a set?
Use reference or character features where the tool offers them, keep one fixed prompt skeleton, change only one variable at a time, and accept that you will discard many outputs. For strict consistency, plan on manual retouching.
Do I have to disclose that visuals are AI-generated?
Platform rules increasingly say yes for realistic imagery, and some advertising regulators do too. Beyond compliance, disclosing it protects your credibility — being caught hiding it costs far more than saying it.
