What open-source video editors are available with 4k capabilities?

Question

Are there any open-source video editors available for Ubuntu that have 4k exportation capabilities?

If not, are there any proprietary (free or paid) license video editors with these skills?

Answer 1

Blender has an integrated Video Sequencer and supports 4K cinema resolution, a proof of that is that Sintel, a movie produced with blender, is available for download in 4K :)
