Sendspark shows a toolbar while you're recording videos so it's easy to pause, restart, or delete recordings.
However, if you do not want this toolbar to show up in your videos, you can hide the recording toolbar to get polished, toolbar-less videos.
How to Hide the Recording Toolbar
Launch the Sendspark Chrome Extension
Click Settings
Toggle Toolbar (On) to Toolbar (Off)
Use Hotkeys
If you hide the toolbar, you can still use the toolbar features with keyboard shortcuts.
Pause & Resume: Alt (ALT) + Shift (⇧) + R
