ESPORTARE UNA CLIP SINGOLA O UN GRUPPO DI CLIP DA UNA SEQUENZA

Instead of cutting the long clip, you can use Scene Edit Detection.

Set to Bin of Subclips.

Batch export these subclips (the ones you don't want, you can chuck out before export)

Premiere doesn't have a regular option for this from the Project panel. But you can do it by selecting the clips in the sequence, right-click "render and replace" ... choose the format/codec you want to export to, probably include handles and include effects.

That will then create all those as clips on disc, which you can use as you wish.

"Restore unrendered" takes your sequence back to the original media.

I've never tried it, but making previews might do it also if you can select the right format/codec. Huh, I need to check on that.
