Tips for Better Videos
Describe the story: "A video about our app" → "A 60-second video showing a stressed founder discovering our app, their workflow transforming, ending with them confidently presenting to investors"
Specify duration: "30-second social ad" vs. "2-minute explainer" sets the pacing.
Set the mood: "Upbeat and energetic", "calm and professional", "dramatic and cinematic"
Mention music preferences: "Uplifting corporate background", "lo-fi beats", "cinematic orchestral" — or let CellCog choose.
For spokesperson videos: Describe the presenter's appearance and tone of voice.
