Lesson 3 of 4 · about 18 minutes
A 30-Second Radio Spot and a 45-Second Reel
You'll be able to
- Fit one message and one ask into a 30-second radio script
- Write a two-voice spot and produce it with Dialogue Editor and SoundStudio
- Script a 45-second vertical reel shot by shot with on-screen text
- Add the sponsorship identification and captions the formats require
Rae Dunmore's polemic ran on July 8. A citizens' group called Fennick Neighbors for Open Bids read it and asked to adapt it. They wanted a radio spot on the county's one AM station and a reel for their page, both pushing people to the July 14 meeting. Rae agreed to write the scripts, as long as every fact stayed tied to the evidence table.
Two formats, two senses. Radio has no pictures. A reel often has no sound. Each version has to stand on its own.
The radio spot: 30 seconds
The module on Video and Radio Ad Development puts natural read speed at about 130 to 150 words a minute. Thirty seconds, minus a sponsor tag and a breath, leaves room for 65 to 75 words. That is one fact, one contrast and one ask. Not two asks. One.
Numbers are hard to hear. A listener in a truck will catch "forty-one thousand" and "four hundred eighteen thousand" if you say them slowly and only once each. Six figures in a row and they hear static. So Rae dropped the 2.3 miles, the dates and the family tie. The family tie is the juiciest fact in the whole file, and it needs context a spot cannot give. It belongs in the article.
Sample: radio script
FENNICK NEIGHBORS FOR OPEN BIDS :30 "Four Hundred Feet"
SFX: Gravel under tires. Truck slows, stops. (0:00 to 0:02)
MAN: Four hundred feet of Cutler Bench Road (0:02)
washed out in May.
WOMAN: Fixing it cost forty-one thousand dollars.
MAN: So the county declared an emergency...
WOMAN: ...and handed out a four hundred
eighteen thousand dollar contract.
No bids.
MAN: State law says jobs that size get
sealed bids.
WOMAN: July fourteenth, nine a.m.,
county commission. Ask them to rebid it.
MAN: Fennick Ledger dot com has the records. (0:25)
TAG: Paid for by Fennick Neighbors (0:26 to 0:30)
for Open Bids.
Words, including tag: 70
A few choices worth copying:
- Cold open. A two-second gravel sound, then a fact. No "Attention Fennick County residents."
- Two voices trade lines. The handoff on "emergency... and handed out" pulls the listener across the turn where the story flips.
- "Sealed bids" is the only legal term. Listeners do not need the statute number. The website has it.
- The date is said as words. "July fourteenth, nine a.m." reads better aloud than "7/14 at 9."
The sponsor tag
Under the FCC's sponsorship identification rule, 47 CFR 73.1212, a station has to announce who paid for a broadcast. When a group pays for material on a political matter or a controversial issue of public importance, the station also has to get a list of the group's chief officers or board members and keep it in its public file for two years. The station handles that file, but expect them to ask you for the list. The tag in Rae's script names the true sponsor, the group, and not an ad agency or a volunteer who wrote the check.
This spot is about a county decision, not a candidate or a ballot measure, so state campaign disclaimer rules do not come into play here. If your spot names a candidate or a measure on an upcoming ballot, check your state's campaign finance law and the FCC political broadcasting rules first. The module on Video and Radio Ad Development covers both.
Producing it
Rae built the read in Dialogue Editor, which handles multi-voice scripts with ElevenLabs voices, so she could hear the timing before booking real voices. Her first draft ran 34 seconds. It had "the Fennick County Commission" where the final says "the county," and a second line about the 2.3 miles. Both went. She kept the slow read on "four hundred eighteen thousand," because that number is the whole spot. The version above times out at 29.6 seconds with the tag.
The group used two volunteers for the final, recorded in a closet full of coats. Rae cleaned it up in SoundStudio: trimmed breaths, added the gravel effect under the open, and checked levels. The module on Audio Editing and Production covers the cleanup. For delivery, ask the station for its file spec and loudness target before you export. Stations differ, and guessing wastes a round trip. StudioConverter can convert the file and set loudness once you know the target.
The reel: 45 seconds
The reel flips every radio rule. Pictures carry it, and text does the talking because a lot of people scroll muted. Voiceover is a bonus layer for those with sound on. As of October 2026, YouTube's help center says Shorts can run up to 3 minutes. Instagram's help center pages checked for this lesson did not state a length, so check the limit in the app before you plan anything over a minute. Forty-five seconds is well under either.
Frame: vertical 9:16, exported at 1080x1920. Keep text in the middle of the frame. The bottom fifth gets covered by captions and the username, and the right edge by the like and share buttons.
Sample: shot list (excerpt)
| Time | Picture | On-screen text | Voiceover |
|---|---|---|---|
| 0:00 to 0:03 | Low shot, tire rolls up to barricade | 400 feet washed out | In May, this happened. |
| 0:03 to 0:08 | Walk along washout edge, handheld | Repair: $41,200 | The fix was priced at forty-one thousand. |
| 0:08 to 0:14 | Drone or long pan of the full road | Contract: $418,600. No bids. | The contract covered the whole road. Ten times as much. |
| 0:14 to 0:20 | Close-up, finger on contract page, date circled | Estimate dated May 28 | The estimate is dated twelve days before |
| 0:20 to 0:24 | Close-up, minutes page | Emergency declared June 9 | the county called it an emergency. |
| ... 0:24 to 0:38: state law card, bar chart from lesson 2, commissioner's quote as text ... | |||
| 0:38 to 0:45 | Commission building, front door | July 14, 9 a.m. Ask them to rebid. Records: link in bio | Be there. |
Steal from that list. The first three seconds show something happening, a tire meeting a barricade, before any text explains it. And the document close-ups are real pages from the records, shot with a phone, with a finger pointing at the line. Viewers trust a page they can almost read more than any graphic.
Trowbridge's quote goes in the reel too, as on-screen text with his name: "That road was going to kill somebody." Fairness does not stop at the article. If you put a person's decision in a video, put their explanation there as well.
Cutting it
Rae shot everything on a phone in one afternoon and cut it in VideoStudio. She burned the on-screen text into the picture and added a caption track for the voiceover too. WCAG 2.2 Success Criterion 1.2.2 calls for captions on prerecorded video with audio, and burned-in text alone does not cover every word spoken. The modules on Video Production and on Video and Reels for Social Media cover framing and captions in detail. She exported once, then ran the file through StudioConverter to get it under the group's upload size without visible damage.
The final check was the same as the radio test, flipped. She watched it on her phone with the sound off. Every number landed. The ask was readable. Done.
Try it
Take your own story from the first two lessons.
- Pick one fact, one contrast and one ask with a date. Write a 30-second radio script of 75 words or fewer, plus a sponsor tag naming who would pay for it.
- Put it in Dialogue Editor with two voices. Time it. Cut until it fits in 30 seconds with the tag.
- Open the audio in SoundStudio, add one sound effect under the first two seconds, and listen in a car.
- Write a shot list for a 45-second reel with four columns: time, picture, on-screen text, voiceover. At least one shot must be a real document from your records.
- Shoot it vertically, cut it in VideoStudio at 1080x1920, add captions, and use StudioConverter if the file is too big.
- Watch the reel muted on a phone. If any fact depends on the voiceover, put it on screen.
Check yourself
1. About how many spoken words fit in a 30-second radio spot read at a natural pace, leaving room for a sponsor tag?
Natural reading runs roughly 130 to 150 words a minute. Thirty seconds minus the tag and a breath leaves about 65 to 75 words.
2. Under the FCC's sponsorship identification rule, 47 CFR 73.1212, what must a station do when a group pays for a spot on a controversial issue?
The rule requires an announcement fully disclosing the true sponsor and, for groups paying for political or controversial-issue matter, a public-file list of chief officers or board members.
3. Why does Rae's reel put the two dollar figures on screen as text, not only in the voiceover?
A reel has to make sense muted. WCAG 2.2 Success Criterion 1.2.2 also calls for captions on prerecorded video with audio.
4. What frame size does Rae export the reel at?
Short-form vertical video is 9:16. 1080x1920 fills the phone screen.
5. What should the radio spot's single ask be?
Thirty seconds of audio, heard once while driving, can carry one action. Pick the one that matters most.
