Get Started FreeFrequently Asked Questions
What is B-roll in video production?
B-roll is the supplementary footage shown while a narrator speaks — it visually illustrates what's being said. In a video about "investing", B-roll might show stock charts, business meetings, or people using computers. B-roll makes videos engaging and informative instead of just showing a talking head.
Can AI automatically add B-roll to my script?
Yes. Paste your script or video topic into Velora and the AI automatically analyzes each sentence, identifies the best matching B-roll footage, sources clips from its library, and inserts them at the correct timestamps in your video.
Can AI generate original B-roll that doesn't exist in stock footage?
Yes. For unique or abstract topics, Velora can generate original AI video clips using frontier models like Veo 3 and Kling AI — creating custom footage that perfectly matches even highly specific script descriptions.
How many B-roll clips can I use in one video?
Velora handles unlimited B-roll clips per video. A typical 10-minute video uses 30-60 B-roll clips, each 5-15 seconds long. All clips are auto-matched to script segments for seamless visual storytelling.
Are B-roll clips from Velora licensed for commercial use?
Yes. All stock footage sourced through Velora is licensed for commercial use in YouTube videos, paid advertising, client productions, and broadcast content with no additional per-clip licensing fees.
