Crop and Resize a Video Capture Source in OBS
Source-checked About 10 minutes
Answer
Select the video capture source, drag handles to resize, hold Alt or Option while dragging to crop, and use Transform for exact framing.
Select the camera and note its framing
Select the Video Capture Device source, note its current Edit Transform values, and check the preview for private information before changing the crop. Lock other sources so the camera is the only layer that can move.
Select the camera source
Click the camera source in the preview or Sources dock and confirm the red bounding box surrounds the intended device. If the wrong camera appears, correct the Video Capture Device selection before framing it.
Resize or crop the camera
Drag a red corner or edge handle to resize. Hold Alt on Windows or Option on macOS while dragging a handle to crop the camera without changing its source resolution.
Set exact camera framing
Open Edit > Transform > Edit Transform, or use Ctrl+E on Windows and Cmd+E on macOS, to enter exact crop, position, size, or rotation values for repeatable camera framing.
Record a framing test
Make a short local recording while moving normally in the frame. Confirm the headroom, background privacy, aspect ratio, and camera overlay remain correct at the final output resolution.
Keep source resolution separate from crop
Cropping hides but does not delete camera pixels, while stretching distorts the image and source-resolution changes can alter existing framing.
Restore the camera transform
Re-enter the saved camera crop, position, and size values when the framing is wrong. If reconnecting the device changed its resolution, correct the device properties before stacking another crop.

If it does not work
- If the crop changes after reconnecting the camera, verify its resolution and Edit Transform values, then restore the saved scene rather than stacking crop filters.
