Two Feeds, Consistent Alignment
Multi-Angle Alignment Assistant
Crosshair and grid overlays across two live camera feeds at once — line up a face cam with a document or desk camera, or keep two stream angles consistently centered so switching between them feels less jarring.
Select two devices and click Start.
Notes
Why the Same Overlay on Both Feeds
The grid and crosshair are drawn identically on both cameras at once, so you have a shared, synced reference for matching subject position between two physically separate cameras — something impossible to judge accurately by eye alone when comparing two feeds side by side without a common frame of reference.
Reference
Common Use Cases
| Setup | Why alignment matters |
|---|---|
| Face cam + overhead desk/document cam | Consistent centering makes switching between them feel intentional, not jarring. |
| Two angles on a multi-cam stream | Matched framing avoids a visible "jump" on every cut. |
| Before/after or comparison recordings | Identical positioning makes the comparison actually valid. |
Step-by-Step
How to Align Two Cameras
- Select both cameras from the dropdowns.
- Click "Start Both" and allow access when prompted.
- Enable the grid and/or crosshair overlay — identical on both feeds.
- Adjust each camera's physical position until your subject lines up the same way on both.
Common Questions
Frequently Asked Questions
What is this useful for?
Any setup with two cameras that need consistent alignment — a face cam paired with an overhead desk or document camera, or two angles you switch between on a stream, where consistent centering between both makes switching feel less jarring.
Does this automatically align my cameras?
No — it provides a shared visual reference (grid and crosshair) drawn identically on both feeds. The actual physical repositioning of each camera is done by you, guided by that shared reference.
Why use a crosshair instead of just the grid?
The crosshair marks the exact center point plus a reference circle, useful for centering a specific small object or point precisely — the grid is better for general rule-of-thirds-style composition across the whole frame.
Can I use this with more than two cameras?
This tool specifically compares two feeds side by side. For additional angles, align each new camera against one of the two already-matched feeds in a separate pass.
Does this work for aligning a webcam with a document camera?
Yes — that is one of the more common use cases, since document and overhead cameras often need centering against a completely different physical setup than a standard face-level webcam.
