Shotcut review
When an edit is finished, I like to pull a short teaser straight from the project. Shotcut is a free desktop editor for Windows, macOS and Linux. You can mark a section of the timeline and export it as its own video.
Pull a teaser from the finished edit
Give the marker a start and an end, then pick that range in Export under From. Shotcut saves the marker with your project. That’s useful when you want to revisit the same excerpt after changing a title or adjusting the sound. Give each range a name you’ll recognise later, especially if the opening and closing clips are both possible teasers.
Keep the file and the post separate
I’d save the teaser with a different filename and watch the export before uploading it. A separate file gives you the same short cut to post on your own site or in another feed. Fanvue offers a different option for locked posts. Its blur setting changes what a visitor sees before unlocking the post. The Shotcut range decides which part of the edit goes into the standalone file in the first place.
Anabel’s take
I’d make one teaser from the existing timeline and keep the marker for the next edit. The useful bit is knowing exactly where that clip starts and ends, then having a file I can check before it goes anywhere.
