Draw over the OBS feed
Guests annotate the programme picture they receive, making the drawing relevant to the exact video, replay, graphic, or demonstration on screen.
OBS telestrator for remote guests
Let contributors draw on the live programme
Guest Connector adds browser-based telestration to a remote guest workflow. Approved contributors see your OBS feed, annotate it with precise drawing tools, and send those marks back to a dedicated production source.
Live annotation
A drawing layer made for production
A useful telestrator needs more than a shared whiteboard. Contributors should be able to mark the picture they are discussing while the producer decides who can draw and where the result appears.
Host-controlled permissions
The room owner decides which participants receive drawing access. A guest does not automatically gain production controls simply by joining.
Dedicated drawing source
Drawing appears through a managed OBS source, letting the producer place the transparent annotation layer into the scene and programme layout.
Multiple drawing modes
Use freehand pens, highlighters, markers, chalk, arrows, lines, circles, squares, pins, numbers, and image placement for different explanations.
Undo and clear controls
Manage drawing history during a live segment, remove an individual action, clear one contributor's marks, or reset the shared layer.
Approved media controls
Alongside drawing, selected guests can receive controls for approved OBS media sources when a clip or replay needs contributor interaction.
Telestration workflow
From guest insight to an on-air mark
Send the programme feed
The approved contributor watches the same OBS output the production is sending back to the room.
Draw in the browser
The guest selects the right tool, colour, width, and opacity, then marks the live picture from their own device.
Use the drawing in OBS
The transparent drawing source is part of the OBS workflow, so the producer controls when and how annotations appear in the programme.
Where it helps
Explain motion, position, and detail live
Remote telestration is useful whenever a contributor needs to point at something more precisely than they can with words alone. A sports analyst can trace a run or identify a player. A teacher can mark a diagram. A reviewer can circle an interface detail. A remote director can indicate a framing adjustment. A guest demonstrating recorded material can pause and annotate a specific moment.
The host retains the production boundary: drawing access can be granted selectively, the source remains under OBS control, and unwanted marks can be undone or cleared. Contributors get an expressive tool without needing remote desktop access to the production machine.
- Sports analysis and replay breakdowns.
- Remote teaching, coaching, and technical explanation.
- Product demonstrations and visual reviews.
- Production notes over live cameras, graphics, or media sources.
Questions
OBS telestrator FAQ
Can every remote guest draw?
Only when the host grants drawing access. Permissions stay with the room owner, so guests can be invited for video and audio without automatically receiving annotation controls.
What can a guest draw with?
The drawing system supports freehand and highlighter-style tools plus shapes, arrows, lines, pins, numbered markers, shadows, erasers, and images.
Can the host remove a guest's marks?
Yes. Drawing history supports undo and removal controls, including clearing a specific contributor's actions or clearing the shared drawing layer.
Does the guest need access to the OBS computer?
No. The guest draws through the browser room, and Guest Connector carries the annotation to the managed OBS drawing source.
