If I'm understanding your question correctly, you're asking if it's a good idea to use a video to explain to potential crowdsourced investors how your platform works? The answer is yes. Video content is an excellent medium for conveying a succinct, compelling message in a crowdfunding campaign. However, the quality of the video must be good so you don't convey mediocrity. No video is better than a poorly made video. I'm happy to hop on a call if you'd like further guidance.

I truly believe any visual content is more appealing than simple text. An animation should be interesting enough to create interest in what you have to offer. Integrate a story displaying real life situations in which your product/service will satisfy or solve a problem. Talk to me about benefits and values your product/service will deliver upon me using it. Show me what's in it for me. Show me how your features/specs will satisfy my needs. Video is great but not everyone is great at storytelling. Hope this helps.
