How to keep your podcast on time
Your guests can’t see the clock on your screen. Give them a big one on a TV: a countdown before you start, the time you’ve recorded and the time of day — and mark the good moments for the edit as they happen.
What you need
- OnAirCut’s Live Switcher, with your ATEM and your audio console.
- A screen your guests can see: a TV or a monitor connected to the Mac as a second display — by HDMI, a USB-C adapter or AirPlay.
- Optional: your show’s or your studio’s logo, as a PNG or JPG.
Choose when it starts: automatically, or when you decide
In Settings → Recording clock, When it starts: Automatically starts the clock with the recording — when you press ▶, since Always REC comes on, or ● REC if you turn it off — so the sound check before it doesn’t count. When you decide lets you start it with ⌘T — or a right-click on the clock — when the episode really begins, even if you’re already recording the warm-up. ■ always stops it, and it stays at the final time.
Choose how it starts counting: right away, or with a countdown
How it starts counting: Right away counts from 00:00:00 at once. With a countdown, STARTS IN first counts down the minutes you choose, so your guests get ready; at zero a message shows for a few seconds — ON AIR!, or your own — and the clock counts from zero. Recording starts at zero, so the wait before the show isn’t recorded.
Whoever is operating sees it too, even without looking at the TV: the app’s clock, next to ● REC, turns amber with a “−” and STARTS IN above it. At zero, ON AIR! appears there as well, with a notice at the bottom — so nobody starts talking before the show does.
The countdown isn’t recorded: recording starts at zero, and the live show goes on as usual in the meantime. If someone starts early, press ● REC: it records from that moment. To record the countdown too, turn on Record during the countdown in Settings → Recording clock.
Never forget to record
- Always REC (Settings → General, on by default): every ▶ records too, and the recording goes with the session — only ■ stops it.
- ■ asks first while recording, and Cancel is the default: a stray click doesn’t end the take.
- The disk is checked before recording: with less than an hour of room, OnAirCut asks before it starts.
Mark the good moments with M
While recording, press M whenever something happens — a clip for social media, a slip to cut. The line under the clock counts them. Each marker shows on the Podcast Editor’s timeline, numbered, and goes into the export: markers in Final Cut Pro and DaVinci Resolve, sequence markers in Premiere Pro. No more scrubbing a whole hour to find that one answer.
Questions
Is the countdown recorded?
Not by default: recording starts at zero, so the wait before the show isn’t recorded, and if someone starts early, ● REC records from that moment. To record it too, turn on Record during the countdown in Settings → Recording clock.
What if the operator can’t see the TV?
The app’s clock, next to ● REC, shows the same countdown, in amber, with STARTS IN above it; at zero it shows ON AIR! too.
Which screens work?
Any display your Mac can use: a TV or a monitor by HDMI or a USB-C adapter, or AirPlay. The clock is a normal window you drag there.
Can I change the message?
Yes: Settings → Recording clock → Message at the start, up to 40 characters. Empty, it says ON AIR!
