Synchronous recording

You can capture video files from multiple sources at the same time synchronously with just a single button - "Tools -> All Tabs Sync MultiCapturing":

But make sure that you have configured all the Input tabs for recording before -- you set the recording format, video and audio codecs, and set the destination path. If one or more tabs are not configured, you'll get notified by the application.

When the synchronous recording is running, you can stop each of the tabs separately. But if you want to stop the recordings synchronously, you should enable this in Settings (go to "Tools -> Settings", and set "Sync Stop for all tabs").

Schedule the synchronous recording

Go to "Tools->Sync Capturing Scheduling" to set the start and stop times for synchronous recording:

You can set only the start, only the stop time, or both at the same time.
