A pitch you've never recorded is a pitch you've never actually delivered.
The gap between how you think you sound and how you actually sound is invariably wider than expected, and video is the only way to close it. Recording a delivery surfaces what no rehearsal can: the pacing that drags, the words you accidentally swallow, the gesture that contradicts what you're saying, the moment your voice goes flat at exactly the line that should land hardest. Eric's recommended practice is to record the same pitch three to five times, watch each playback with the checklist in hand, and identify one specific change to test on the next take. Iteration, not repetition, is what builds delivery.
The three things video reveals that nothing else does:
In this video, Eric walks through the video practice loop, including how to set up a basic recording, what to look for on playback, and the iteration cycle that turns a good written pitch into a great delivered one.
