I wanna thank all of your for your input! You confirmed my fear the problem would not be easily fixable, and I took some of your advice about how to proceed. What I ended up doing was to come up with something like this. There are many soundbites by different people, and I alternate them between left and right – it’s not so bad in the end. Since the material was shot in 1080p, and the final video will be 720p I got some leeway. So I was able to zoom in a bit and move around the frame rather freely.
Thanks a lot for the fast response! Well, I don’t get paid for this at all, so it’s not really an option to use the roto-brush. That’s why I was thinking “outside” standard keying, and maybe just applying some effect that “hides” the background by treating the whole scene, and still remaining somewhat professional.
And since it’s all done in 2D there is no camera position I have to chose. It’s an entirely flat composition.
My guess is that this is exactly the problem – that I can’t really create the right feel without going 3D. Problem is I have no clue how to do it in 3D, even though I imagine it to be very simple.
You are propably right. I can delete some of that stuff. The rest I either keep on the HDD or copy to tape.
Already the effort to find a proper codec for transcoding takes time, not to mention the actual transcoding itself.
