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.
