AI Video Tools: common questions
Which AI video tool is best for beginners?
If you want results without learning a timeline, start with an avatar tool like Synthesia or HeyGen — you write a script and get a presenter video. If you want cinematic generative shots, Runway is easier to control than most model-specific apps.
Are AI-generated videos safe to use commercially?
Usually yes on paid plans, and usually not on free tiers. Commercial rights typically start at the first paid plan, but every vendor defines it differently — check the specific plan before you ship client work.
Why do AI video tools use credits instead of minutes?
Because a 5-second 4K clip costs far more compute than a 5-second 480p clip. Credits let vendors price by GPU time. It also means your real monthly cost depends on resolution and length, not on a flat minute count.
