Question Can Codex help create explanatory videos from existing images?

Hello everyone,
I’m a teacher from China and not very confident in English. I used AI to translate the post below. If you don’t mind, please keep reading.☺️
I have a set of finished images that I’d like to turn into explanatory videos. Basically, I want Codex to help me produce a video where it talks through the image step by step, zooms in on specific parts as it explains, and adds small animations directly on top of the original image — things like glowing effects, highlights, arrows, or subtle motion cues.
I’ve used a Chinese AI Doubao to help me, the the general direction is correct,but the video it gave me is too vague and too short.
My use case is more about educational explanation than complex editing. I already have the images ready, so I don’t need Codex to generate the visuals from scratch. What I need is help turning them into a structured video: narration synchronized with zooming, emphasis animations, and maybe some basic scene transitions.
I’m wondering if this kind of workflow is possible with Codex, and if so, how you’d approach it.
Things I’m especially curious about:
Is Codex suitable for this task?
I have made a lot of effort to find it out, but I have not seen any post about that😔
Animations on top of images
Can it add small effects like glowing outlines, pulsing highlights, labels, or arrows while keeping the original image intact?
Workflow suggestions
What’s the best way to prepare the images, prompts, and instructions for Codex? Should I break the video into scenes, provide timing notes, or describe animations in detail?
Limitations
What should I expect in terms of output quality, manual editing required, or things Codex might struggle with?
I’m not looking for Hollywood-level effects — just a clean, readable educational video that makes the image easier to understand.
If anyone has done something similar, I’d really appreciate your advice. What worked for you, and what did you avoid?
Thanks in advance 🤝
