Should you build or buy Stock Video & B-Roll Library?
Stock video and B-roll libraries give video producers, marketers, and content teams access to pre-licensed footage for use as supplemental visuals in productions, ads, documentaries, and social content. These services offer searchable catalogs of generic and specialized clips with rights clearance built in.
The build-vs-buy decision for Stock Video & B-Roll Libraries turns on how fast AI video generation has become production-ready for standard footage categories versus how much catalog depth still matters for specialized, authentic, or complex footage your editors actually need; the specifics decide it, and the standard B-roll case is shifting quickly.
Build it, buy it, or bridge?
When building makes sense
Generic B-roll has always been the most replaceable part of video production, and AI generation is accelerating that. RunwayML Gen-3 and Kling produce usable shots — a busy sidewalk, a person typing at a laptop, a city skyline at dusk — in seconds. For productions where the B-roll purpose is ambient, lifestyle, or contextual, AI generation now covers a meaningful share of catalog use cases at 2-3x lower cost than subscription services. The rights picture is also cleaner: AI-generated footage is original output without a licensor chain. Teams producing marketing video, social content, and branded media at volume, where no individual B-roll clip needs to be authentic footage of a real place or person, have a credible case for shifting to AI generation as the primary source.
When buying makes sense
Catalog subscriptions like Artlist and Storyblocks earn their keep when footage needs are specific, authentic, or complex. Documentary-style productions require real footage of real places and people. Sports content requires actual game footage. Complex motion sequences, aerial cinematography, and highly specific location footage favor catalog depth that AI generation can't yet match at production quality. Even for lifestyle content, catalog footage offers a level of authentic human movement and spontaneous behavior that AI-generated clips don't fully replicate. For teams with varied footage needs — some generic, some specialized — a subscription gives catalog depth for the specialized cases while AI handles the volume work.
The desk read
Generic B-roll has always been the most replaceable part of video production, and AI video generation is making that replacement faster. RunwayML Gen-3 and Kling are already being used in production pipelines for standard environmental shots: a busy sidewalk, a person at a laptop, a city skyline at dusk. For those cases, the quality gap between AI-generated and catalog footage is closing quickly, and the rights situation with AI-generated footage is cleaner.
Catalog subscriptions like Artlist or Storyblocks still hold real value when you need hyper-specific footage, documentary-style authenticity, complex motion sequences, or coverage of specific sporting events and real locations that AI can't plausibly fabricate. The build case, meaning AI generation as primary B-roll source, gets compelling when your content is lifestyle, ambient, or generic enough that any competent AI clip serves the edit, and you're generating enough footage that per-clip catalog costs add up.
