Audio-only podcasts: when video is not worth it

An audio-only podcast is distributed as sound alone, through an RSS feed that podcast apps read. There is no accompanying video track, and the listening experience is designed to work without a screen.

This was simply what podcast meant until video versions became common. The distinction is now worth making because the two formats have diverged in how they are made, where they are found and how they are consumed.

It fits where listeners already are. Podcast listening happens during commutes, walks, washing up and workouts, all situations where a screen is unavailable. A format that demands attention on a screen competes for a much scarcer resource.

It is dramatically cheaper to produce. No lighting, no framing, no camera, no wardrobe consideration, and an edit that deals with one track instead of synchronised picture and sound. For a small team this difference decides whether the show ships weekly or monthly.

It lowers the barrier for guests. A guest who would decline a filmed interview will often agree to a phone or online conversation, which widens who you can realistically book.

It is more forgiving. A cluttered room, an off day and a plain background all disappear when nobody can see them, and the attention you save goes into the conversation.

Discovery is the real cost. Video platforms have recommendation engines that put unfamiliar shows in front of people, and podcast apps largely do not. Audio-only shows tend to grow through recommendation, search and existing audiences rather than algorithmic discovery.

Short-form clips are harder. A vertical clip with faces performs differently from a waveform with captions, and clips are how a great deal of podcast growth now happens.

Some subjects genuinely need pictures. If you are demonstrating a technique, reacting to an image or walking through something visual, audio forces you to describe what a camera would simply show.

Ask what your listener is doing while they listen. If the honest answer is driving, walking or working, a screen adds nothing they can use and video is production cost without a return.

Ask whether the content is visual. Conversation, storytelling, interviews and commentary lose nothing without pictures. Demonstrations, reviews of physical objects and anything you would point at do.

Ask what you can sustain. A weekly audio show beats a monthly video show for almost every goal, because consistency is what builds a listening habit. Choose the format you can still be making in a year.

Many shows record video and release audio as the primary format, using the picture for clips rather than for a full episode. This gets you the discovery benefits without committing to a video edit every week.

If you do this, make the audio edit the master. Cut for the ear, then let the picture follow, rather than cutting for the eye and accepting whatever the audio becomes.

Short clips pulled from an audio episode, with captions, cover most of what a full video release would have earned you at a fraction of the effort.
