Import BRoll

Import BRoll

The Import B-Roll feature lets you bring external footage—stock clips, archival material, VFX plates, brand assets or previously rendered ACT 3 shots—into any project without leaving the ACT 3 AI Video Editor. It extends ACT 3’s “idea-to-screen” pipeline by giving editors a fast way to weave supplemental visuals into AI-generated scenes, title sequences or marketing cuts.

What It Does

One-click ingest for MP4, MOV, ProRes 422/4444 and image-sequence folders (PNG, EXR). The same Import/Export Bridge that handles scripts and EDLs also accepts B-roll video formats  .

Automatic transcoding to ACT 3 mezzanine codecs so playback and rendering stay seamless across web and desktop.

Smart tagging that reads filename, metadata and AI scene analysis to auto-label clips (e.g., “city-sunset, drone, 5 sec”).

Drag-to-timeline placement; clips appear as blue strips on the Timeline & Storyboard track beneath generative shots for clear visual separation.

Credit-free usage – importing B-roll does not spend credits; credits are only consumed when re-rendering the final cut.

Cloud-synced storage with per-org quotas (clips count toward your cloud-storage limit; a progress bar warns at 90 %).

Proxy workflow – ACT 3 auto-generates lightweight proxies for smooth editing and swaps back to full-res during the final render pass.

Typical Workflow

From the Media panel, click Import B-Roll or simply drop files onto the browser window. Review auto-tags, retitle if needed, then choose which Episode ▸ Scene the footage should live in. Drag the clip onto the timeline; snap points and ripple-edit tools keep generative shots in sync. Use Blend Mode and Opacity controls to overlay logos or lower-thirds. Trigger an Export Preview to verify colour-space and frame-rate consistency before the final GPU render.

Permissions & Governance

Only members with the Use Credits or Modify/Edit role can add or replace B-roll clips (see Roles & Permissions).

All uploads pass through the platform’s three-stage Inappropriate Content Scanner before syncing to shared workspaces  .

Best Practices

Keep original frame rate if you plan to align B-roll audio; ACT 3 will respect source FPS during conform.

Large 4 K masters consume storage rapidly—use the Generate Proxy toggle on import.

Use tags like “PR-approved” or “licensed-2025” so a quick search surfaces only rights-cleared material.
