AI 视频生成也太好使了，一个入口体验多个图生视频模型 如果平时会用图片转视频，很容易遇到一个问题：不同模型各有所长，同一张图在 Veo 、Kling 或 Seedance 里的效果可能完全不同。 为了对比结果，经常要在几个网站之间切换，重复上传素材、调整参数，整个过程比较割裂。 Image to Video AI 把 Veo 、Sora 、Kling 、Seedance 、Runway 等模型放到了同一个入口。上传 JPG 、PNG 或 WebP 图片，再写一句运动提示词，就能选择模型和画面比例生成视频。它还支持镜头平移、缩放、倾斜、首尾帧控制，以及最高 4K 、无水印 MP4 输出。 网站里有一些不同场景的生成案例，可以直接看看各类图片动起来后的效果。如果你也在测试图生视频模型，可以体验一下，也欢迎分享实际效果和踩坑经验。 https://imagestovideoai.com/

It uses GLM-5.2 fast via Fireworks to generate the scripts and image prompts and, like I said, Nano Banana 2 Lite for the images, gpt-4o-mini-tts for the narration, and ffmpeg to string it all together and add the Ken Burns zoom effect (which still has a shake I haven't been able to get rid of). The video compilation proved to be the blocker once the rest was in place, but I was able to speed that up by putting it on a 64 vCPU EC2. The cost might be the most interesting aspect as the short form videos tend to be about 25 cents. Almost 90% of that is the images, which are 3.336 cents a piece. Of course, running
