YouTube show vs Shorts series: make long-form episodes with Timeline

What is the difference between a show and a Shorts series?

The Shorts series is the vertical, short version. YouTube's page says a Shorts series playlist must contain only Shorts, portrait or square, with a maximum duration of 180 seconds, and that these series appear with a Shorts icon in the Shows tab on web and mobile.

A regular show has the same structure of seasons, episodes, banner and backdrop, and the same quality standards, but the page states no 180-second cap for it.

Rendering long episodes on Sume

Timeline 1.0 takes an audio length from 1 to 1800 seconds and up to 200 video slots, so a 30-minute episode is the ceiling. Above 12 slots the default strategy renders in chunks, and a request that forces a single pass above 12 slots is refused with render_strategy_unsafe.

The default output is still 1080x1920. For a landscape show, set output.width and output.height, for example 1920 and 1080, both even numbers within 256 to 2160, and pick a fit per slot.

• Up to 1800 seconds of audio per render.
• Up to 200 slots.
• Set output size for landscape.
• Import every source file to media.sume.com first.

Cost of a long episode

The rate is $0.10 per output minute, rounded up, so a 22-minute episode bills 22 minutes, $2.20 for assembly, before the cost of clips and voice. The plan endpoint returns billable minutes without charging, so check it first.

Long episodes stress the render queue. Submit with an Idempotency-Key, poll the job, and read warnings, which are soft notes and not failures.

Choosing between the two

If viewers come to your show from the feed, in short bursts, the Shorts series is the format the page was written for. If they come for a longer sit-down watch, a regular show fits. Make that choice before you commission the season, because converting later means re-cutting every episode.

A hybrid is possible too: keep a Shorts series for teasers and a regular show for the full episodes. They are separate playlists with separate rules, and the Sume side is the same Timeline call with a different audio length and output size. Cut the teaser from the same audio and video sources with source_in, so the two stay in sync.
