After using kino for years for editing dv camera footage, I've finally started moving towards HD formats where Kdenlive really is the tool. I was there in 2005 when kino was not very stable under Debian unstable, eh, so I'm not put off by the kdenlive problems (a few crashes, timeline corruptions) I've seen so far. Only things I miss in kdenlive are the levels/white balance effects in kino which are great for making footage look like it came from one camera, and for faking good shooting conditions.
Here my first trial. Base editing of clips and leveling/white balancing done in kino, and final audio sync in kdenlinve:
Here's a second trial, pure kdenlive this time due to 720p video. It really needs some levels/white balancing, doesn't it. And the audio sync was messed on a few occations when the timeline somehow got corrupted; some clips were put off by a 1-5 frames, almost random from what I can tell. But I tried redoing it once, though some parts slipped through I think.
I have never used commercial video editing systems on Mac or MS Windows, so I'm not sure how they'd work out. Or what kino and kdenlive miss. But I'm a rather happy user. Thanks, kdenlive developers!
