그록 유료화 충격! 무료 AI 영상 툴 BEST 7 | 이미지→영상 직접 비교 (2026)

With Grok suddenly switching to a paid model, I noticed many people are looking for alternatives. I also found out about it on the day of the change while preparing for an institutional lecture, so I personally tested various sites. Excluding those that generate content only once and then disappear, I selected only the ones that are actually free to use and have summarized 7 options for you. I also tested converting images into videos, so please check the video for a comparison of the results. However, please note that policies regarding free credits or recharge timing change frequently for each tool, so I am providing this information based on the time the video was filmed. Please keep in mind that there may be changes.
