AI video tools span a fast-moving range of use cases: turning text or images into short clips, generating lifelike avatar presenters that speak your script in dozens of languages, and automating editing tasks like captions, background removal, and highlight cuts.
Pick based on the job at hand. Generative video suits concept and social content, avatar tools shine for training and explainer videos, and AI editors save hours on routine post-production. Check output length, resolution, and pricing, since video generation is often the most credit-hungry category.
Separate generating a new shot, presenting a script, and editing existing footage. These jobs need different controls. Use a short storyboard and an exact delivery format to compare candidates.
Check continuity between frames, lip sync where relevant, readable captions, and the ability to change one shot without rebuilding the whole sequence. Export a sample before paying so resolution, watermarking, and aspect ratio do not become last-minute surprises.
Estimate the cost of usable finished seconds, including failed attempts and revisions. Keep human review over likeness permissions, licensed audio, and any statements spoken by a generated presenter.
