Pick moments that stand alone
A good clip makes sense to someone who's never seen the full video: a strong opinion, a funny exchange, a surprising answer, a clear piece of advice.
Skip moments that need context ("as I said earlier...") unless you can add it in a caption.
Cut to vertical properly
Keep the speaker's face in frame as they move. If two people talk, switch between them rather than squeezing both in.
Add captions - most viewers will be watching without sound.
Give each clip its own hook
Start on the most interesting sentence, not the start of the conversation. You can add a short title card or caption that sets up the question.
Only clip what you own
Clipping your own long videos is fine. Clipping someone else's needs their permission, or it's likely to be claimed or taken down.
TallClip's Clips tool finds strong moments in a long video you own, reframes them to vertical and adds captions.
How long each clip should be
Most strong clips are 20 to 60 seconds. Cut in after the setup and out right after the payoff. Ending a beat early, on the strongest line, often works better than letting it trail off.
If a moment needs two minutes to make sense, it's probably better as a longer clip on the main feed than as a Short.
Link the clips back
Every clip is an advert for the full video. On YouTube, you can link a Short to a related long video so viewers can tap through to the whole thing.
Mention the full episode in the caption or description, and pin a comment with where to find it.
Make a habit of it
Clip each long video the week it comes out, while it's fresh. Post the clips over the following days so the long video keeps getting new viewers.
Keep a note of which moments did best. Over time you'll learn what your audience wants from the long videos too.
Questions
How many Shorts can I get from one long video?
A one-hour podcast often has five to ten moments strong enough to stand alone.
