I think you're massively underestimating the amount of work that goes into making a Kickstarter video there tbh. Even the video we had there probably took the team a solid two or three weeks, from me writing the script and shooting the video to all the programmers fixing problems and implementing new features so we could have enough "good" gameplay footage to show, to the artist making the maps and staging the combat scenes and recording the gameplay footage and then slicing everything together. The content is the problem, not the actual cutting together of the video ... although that does also take time.
Your initial comment on our video was that we needed more staff talking (which we don't have) and more dynamic gameplay, which we didn't really have at the time either (no realtime geoscape or air combat). Also Sven can probably afford to spend plenty of time casually walking around the office chatting to people in his Kickstarter video updates because a) he actually has an office, b) he's probably not project managing the entire team on a day-to-day basis, and c) he's probably not replying to the Kickstarter messages / comments on a day-to-day basis either.
Realistically none of that could be easily fixed, which is why I think we did a pretty good job with what we had available to us. I don't have a problem admitting that our video and campaign isn't up to the standards of some of the bigger and more successful Kickstarters by bigger and more successful companies, but we don't have the manpower to match them - particularly when the team need to be focusing on the closed beta we now need to deliver in three months!
