Most guides rank AI video tools on how good the video looks. That is the wrong first question if you are getting paid for the work.
A tool can make beautiful footage and still be useless to you. The plan you are on might not allow paid work. The watermark might stay after you upgrade. The company might train its models on the client footage you uploaded.
This guide sorts the main tools by the job you need done, and tells you what to check on each one before you put its output in front of a client.
Key takeaways
- OpenArt is the best pick for creators and teams who want the whole pipeline, with commercial use included from the Advanced plan up.
- Runway has the most relaxed licensing of the group, which makes it easy to test before you commit.
- HeyGen is the strongest avatar tool, and its free plan does not allow commercial work.
- Synthesia suits corporate training, but its stock avatars are off limits in paid ads.
- The cheapest tools are usually the ones most likely to train on what you upload, so read that clause before client work.
What to check before you use one for paid work
Which plan turns commercial use on
This is the one people get wrong. Commercial rights start at a different tier on every platform, and free plans usually ban paid work outright. Find the exact plan, not the marketing page that says "for professionals".
Whether the watermark really goes away
Paid plans remove the visible watermark almost everywhere. What catches people out is that on some tools a video you made on the free plan keeps its watermark forever, even after you upgrade. If you are trialling a tool for real work, start on the paid plan.
Who owns what you make
Most companies say the output is yours. Read what they keep as well as what they give you, because some hold a broad license over everything you upload and generate.
Whether they train on your uploads
This is the clause that should decide it for anyone working under an NDA. Some companies promise never to train on customer content. Some only promise it on enterprise plans. Some allow it outright with no way to opt out. A client's unreleased product footage sitting in a training set is a real problem, not a theoretical one.
Who covers you if someone makes a claim
Almost every tool puts the risk on you. A small number of enterprise plans cover you instead. If you run an agency, this is worth asking about directly before you sign anything.
1. OpenArt
Best for: creators and teams who need the whole pipeline
OpenArt is the strongest all-round pick because one subscription covers images, video, voice, and editing, and everything runs off one pool of credits. You are not stacking four tools and four licenses to finish one job.
OpenArt Director is the part that makes it usable for real deliverables. It builds multi-scene videos up to five minutes with the same characters, places, and voices across every shot, and you fix individual shots by chatting. Nine templates cover common jobs, including Short Film, Product Ads, and UGC Ads. Smart Shot turns one prompt into a run of cuts with different angles instead of a single clip.
The saved character library is what keeps a campaign consistent. Build a spokesperson or a mascot once with OpenArt Characters and bring the same face into every video and every format. Brand Kit does the same for your logo, colors, fonts, and rules.
Because OpenArt aggregates models rather than betting on one, you get several current engines under the same account, including Seedance 2.5, Kling Omni, Veo 3.1, Wan 2.7, and LTX 2.3. Use the AI video generator for text to video and image to video, and switch models as the leaders change. Voice cloning and voiceover cover more than 30 languages, and output reaches 4K depending on the model.
There is also an IP Safety Check you can run before you publish. It flags when a generation looks close to protected work or a real person's likeness. It is a review step rather than legal cover, but it gives an agency something concrete to do before a campaign ships.
Two things to know. Commercial use starts on the Advanced plan at $29 a month, so the $14 entry plan will not cover client work. And because the video models come from third parties, the exact lineup changes over time.
2. Runway
Best for: frame-level control, and testing before you commit
Runway builds its own models and is unusually good at editing rather than only generating. You can make a change on one frame and have it carry through the rest of the video, and its motion capture tools let a real performance drive a generated character.
Its licensing is the most relaxed of the group. Commercial use is allowed on every plan, including the free one, which is rare enough to matter. The free output carries a watermark, so it is for testing rather than delivery, but you can prove the workflow before you pay.
The limits are length and sound. Clips are short, so anything full length means stitching several together, and there is no audio generated with the video. Training protections and other contract-level cover sit on the enterprise plan rather than the standard ones.
3. HeyGen
Best for: presenters, spokespeople, and dubbing
HeyGen turns a single photo into a presenter who speaks your script with natural blinking, expressions, and gestures. Its translation and dubbing cover a very long list of languages with voice cloning and matched lip movement, which is why localization teams keep landing on it.
Commercial use comes with every paid plan. The free plan is explicitly not for commercial work, and that includes monetized video and anything you do for a client.
The thing to plan around is credits. Avatar video is billed by the minute, so a small script fix that forces a re-render costs you the minute again. Also check the training clause on the plan you are buying, because the default differs between enterprise and everyone else.
4. Synthesia
Best for: corporate training video
Synthesia is the default for training and internal comms. It turns a script into an avatar presentation in a long list of languages, and it exports in the formats learning teams need for their course platforms.
It also carries the security paperwork and admin controls that bigger companies ask for, which is often the reason it gets chosen over something better looking.
For advertising, there is a hard limit you need to know about. Synthesia does not allow its stock avatars in paid advertising, so it is not the tool for performance creative no matter which plan you are on. Its free plan also adds a watermark and does not let you download.
5. The cheap entries: Kling, Pika, and Luma
Best for: low-cost testing, with one clause to read first
These three are the least expensive ways to get commercial rights, and the quality is good. Kling in particular does very well when people compare outputs blind.
The trade-off is what their terms allow. The cheaper platforms are generally the ones most likely to train on the content you upload, and some offer no way to opt out. That is fine for your own marketing and not fine for a client under an NDA.
One more thing on Luma. A watermark from a free generation stays on that video permanently, so if you plan to use anything commercially, start on the paid plan rather than upgrading later.
Also worth a look
- Canva. The AI clips are short, but the templates, Brand Kits, and one-click resizing around them are the real product. Best if your team already designs there.
- D-ID. The cheapest way into avatar video, and the one to look at if you want a real-time conversational avatar rather than a rendered clip.
- Krea. Aggregates a lot of models, and it does not train on customer content, which makes it a sensible budget pick for client work.
- Higgsfield. Strong cinematic camera control and reusable characters, with plugins for the editors your team already uses.
- Midjourney. Image to video only, and commercial use needs its top consumer tier.
- Pictory and InVideo. Both lean on licensed stock alongside generated clips, which suits long-form and explainer work.
Before you sign off on client work
Run the same four checks every time, whatever tool you land on.
Confirm the plan you are actually on includes commercial use, not the plan above it. Confirm nothing in the final export carries a watermark from an earlier free generation. Confirm the terms on training, and get a written carve-out if the work is under an NDA.
Then handle the things no license covers. Get written consent from anyone whose face or voice you clone. Check the current AI labelling rules on the platform where the video will run, because those change often and a commercial license does not satisfy them. And remember that owning your output is not the same as clearing a logo, a piece of music, or someone else's artwork that appears in it.
Which one fits you
Solo creator earning from content. OpenArt on the Advanced plan. Image, multi-scene video, voice, and music sit in one credit pool, and the characters you build stay yours to reuse.
Marketing team. OpenArt for ad and product video, with the Brand Kit doing the consistency work. Add Canva if most of your output is static graphics, or HeyGen if you need a spokesperson in several languages.
Agency or studio. Ask about cover before you ask about quality. If a client requires the vendor to stand behind IP claims, that narrows you to enterprise agreements very quickly. Keep NDA work off any platform that trains on uploads.
Small business owner. The cheapest commercial plans will do the job for your own marketing. Spend the extra few dollars on a tool that does not train on your uploads if you handle anything sensitive.
The bottom line
Pick the tool on its terms first and its output second. The best-looking model in the world is worthless to you if the license does not cover the work you are being paid for.
OpenArt is the top pick because one subscription covers the whole job, the characters and brand assets you build carry across everything you make, and commercial use is included from the Advanced plan up. Runway is the easiest to test on, HeyGen is the strongest for presenters, Synthesia owns corporate training, and the budget tools are fine for your own marketing as long as you have read the training clause.
Whatever you choose, check the terms on the day you buy. They change, and the version you read six months ago is not the one you are agreeing to now.
Frequently Asked Questions
Which AI video generators allow commercial use?
Nearly all of them do at some plan. What changes is where that plan sits. Runway allows it even on its free, watermarked plan. HeyGen includes it on every paid plan and bans it on free. OpenArt includes it from the Advanced plan up, and its entry plan does not. Always confirm the tier rather than assuming any paid plan counts.
Can I use free-plan video in an ad or a monetized post?
Usually not. Most free plans limit you to personal use, and several ban monetized and client work by name. Runway is the notable exception, though its free output is watermarked. If the video is going to earn money, make it on a paid plan from the start.
Will the watermark disappear when I upgrade?
Not always. On some platforms the watermark is baked into the file at the moment you generate it, so upgrading later does not clean up the videos you already made. If you are testing a tool for real work, run the test on the paid plan.
Do these companies train on the videos I upload?
It depends entirely on the company and often on the plan. Some promise never to train on customer content. Some only promise it to enterprise customers. Some allow it with no way to opt out. Find that clause before you upload anything belonging to a client.
Who owns the video an AI tool makes for me?
Most companies say you own the output, and OpenArt makes no ownership claim over what you generate. Owning it and being able to stop others copying it are different things, though, and purely machine-made work is on shaky ground for copyright in a lot of places. Treat your license as permission to use the video, not as a monopoly on it.
What should an agency ask for before using one of these?
Three things. A written agreement that your client footage will not be used for training, a clear statement of which plan carries commercial rights, and whether the vendor will stand behind you if someone makes an IP claim. That last one narrows the field fast, and it is usually an enterprise conversation.
