Your B-roll,
placed where it
means something.
Sapari's AI director reads your transcript and drops your assets at moments that fit. Or place them manually. Three visual modes: overlay, replace, insert.

The problem
10% judgment.
90% clicking.
You know which shot goes where. Actually dragging each one onto the timeline, setting the in and out, fading — that's the tax.
Most AI editors skip the problem and leave you to place B-roll by hand. Or they fill the gap with AI-generated stock footage that feels generic and brand-misaligned.
Sapari takes a third path: the assets are yours, and the AI only decides where they land.
How it works
Four steps.
Upload
Drop B-roll videos, images, logos, or product shots. The library persists across projects.
Describe
Optional hint per asset.
"Product shot of the red running shoe."
Configure
Per asset: visual mode, audio mode, duration, position.
Analyze
AI director matches transcript context to asset descriptions. Suggests placements.
Up to 10 assets can be marked AI-directed per analysis, placed up to 30 times total. Fixed placements are unlimited.
Three placement modes
Mix and match per asset.
Fixed
You specify the exact timestamp. Deterministic. Unlimited count.
AI-directed
AI picks the timestamp based on transcript context. Reviewable on the timeline.
Manual
Drag onto the timeline in the editor. No AI involvement.
Your opening title goes fixed. Product close-ups go AI-directed. The five logos you always drag manually stay manual. Once configured, an asset keeps its settings across projects.
Three visual modes
How each asset shows up.
Overlay
Asset layers on top of the main video. Picture-in-picture for product shots, lower-thirds, watermarks.
Replace
Cut from speaker to the asset for the asset's duration, then back. Used for charts, screenshots, full B-roll moments.
Insert
Splits the timeline at that moment and inserts the asset between the halves. Adds duration instead of overlapping.
Per-asset control
How each asset shows up.

Shared asset libraries
Upload once, reuse across projects and teammates.
Beat-synced placement
Land assets on the song's rhythm for music-forward clips.
Editing templates
Save a placement pattern and reuse on future videos.
Before you ask
Common questions.
Does Sapari generate stock B-roll for me? +
No. You upload your own assets, and the AI director places them. It doesn't invent footage.
How many assets can I upload? +
Storage scales with your plan. Creator is 25 GB, Viral is 100 GB. You can reuse the same asset across every project.
What if the AI places an asset wrong? +
Drag the boundary, or dismiss the card and the asset drops out. Same review model as every detection.
Can I use the same asset in multiple projects? +
Yes. Upload once, reuse everywhere.
What file types work? +
MP4 and MOV for video, PNG and JPEG for images. Transparent PNGs work for logos and watermarks.
