    How would I create a video like this?

    For example, I have several posts that explain concepts in detail, with supporting images. They're written in Markdown, and I keep refining them until I'm confident that the average person can read them and immediately understand the concept.

    The problem is that text is becoming a less popular medium for learning, while short form videos are increasingly being used to explain the same ideas.

    From what I can tell, this tool only lets you provide a prompt. Can it turn my existing Markdown posts and images into videos, or is it mainly intended for generating videos from simple prompts? I'm looking for something that preserves the explanations I've already written rather than creating something entirely new.

      it works, but can u add different style of videos like this one:

      Style 1: https://www.youtube.com/shorts/vGjrv2zjfsM

      Style 2: https://www.youtube.com/shorts/6KoRHpAZ4zk

      These are the two styles that consistently keep me watching. I can't really describe them well in words, so I linked the videos directly to avoid losing important details in the translation from visual format to text.

      Maybe someone with more experience in video production can explain what techniques are being used here and why they're so effective at holding viewers' attention.

      So this is really just a kinda proof of concept, but I'd be pretty easy to turn it into what you want. It sounds like you've already got both basically a script and images to go with it?

        Your project reminds me of something I built a while ago using Pollination.ai for images, Gemini Flash for script / captions / inserting transitions and all other editing, Google Cloud TTS for narration/voice, and FFmpeg drive by flash, back then Gemini Flash 2.5 (free) is what i used for these experiments. The result looked like this:

        I wasn't happy with how it turned out, so after making 3–4 videos I dropped the idea.

        Later, I came across several different video styles that consistently kept me watching. That's when I realized what my videos were missing they simply didn't have the same ability to capture and hold attention.

        But i never managed to generate those styles after dozens of attempts and gave up.

    Fun idea! Hope it doesn't cost you too much to keep up depending on how much traction this thread gets ;)

    One small quirk I noticed with the generated short video: for each new slide/photo, there is a very gradual "zoom in" effect that occurs, which causes text to jitter a bit and is a bit disorienting. Not sure if that is specific to the "The Great Molasses Flood of 1919 in Boston" prompt I used or not.

    Also, is Claude involved in the video generation itself? I noticed the generated video has "By Claude" in the top left corner, but the logs seem to indicate that only GLM-5.2, Gemini Flash, and GPT-4o are involved (just curious!)

      Yeah, that's suppose to be a Ken Burns style zoom but I haven't figured out how to stop the shake the should probably just remove it. And I need to remove the "By Claude" too. That's a remnant from porting from my internal framework for the [By Claude)(https://www.youtube.com/@byclaude) Youtube, TikTok, etc channels.

    Ugh looks like I'm hitting my Gemini Tier 1 usage limits. Sorry!
