Screen capture lets you record a window on your computer and stream frames to Atomscale in real time. This is currently used for RHEED data: frames are captured from your RHEED software window, uploaded continuously, and analyzed with the RHEED Fingerprinting workflow.
How to Stream
Open the Add Data dialog
Click Add Data in the sidebar, then select the Stream tab.
Choose a capture source
Click Choose source. Your browser will prompt you to select a window, screen, or tab to capture. Selecting from the Window section is recommended for best results.
Position the capture area
A live preview of your selected source appears. Drag and resize the capture area overlay to frame the region you want to record.
Configure stream settings
Fill in the configuration form: Start streaming
Click Start Stream. Frames are captured and uploaded in the background.
Control the recording
While streaming you can Pause, Resume, or End Stream. An elapsed-time timer is displayed in the controls.
You can close the Add Data dialog while a stream is active. The recording continues in the
background, and the sidebar button shows the stream status.
Interrupted Streams
If a stream is interrupted (for example, by closing the browser tab), Atomscale marks it as interrupted the next time you open Atomscale in the same browser. An active stream that receives no data for two hours is also marked as ended with an error. Neither can be resumed. To finalize the data already captured, open the stream’s data item page, click Stream Settings, and end the stream. To keep recording, start a new stream.
