Frequently Asked Questions
What's the best tool to find a specific moment in a YouTube video?
For finding specific moments you can describe, MomentClip is the best option because it uses multimodal AI to search both audio and visual content. For finding generic 'viral' moments automatically, Opus Clip or Klap work well. For simple keyword search in transcripts, YouTube's native search is free.
Can I search for visual content in YouTube videos?
Only MomentClip currently supports visual content search using multimodal AI. Other tools like Opus Clip, Klap, and Descript only analyze transcripts, so they miss charts, product demos, whiteboard explanations, and reactions.
What's the difference between transcript search and multimodal search?
Transcript search only looks at spoken words (converted to text). Multimodal search analyzes both audio AND video frames, understanding visual content like charts, demos, text on screen, and non-verbal reactions.
Which tool is best for making TikTok clips?
Opus Clip and Klap are optimized for auto-generating short-form clips with virality scoring. MomentClip is better if you want to find specific moments rather than letting AI choose for you.
Is there a free way to search inside YouTube videos?
YouTube's native transcript search (Ctrl+F in the transcript panel) is free but only supports exact keyword matching. MomentClip offers 1 free video analysis for natural language search.
