OK, I'm going through v1.0 and I've made a huge decision. There are so many issues I want to address that I think it just might be better to start the editing process from scratch and make it v2.0.
I may still change my mind though, since it will mean redoing the colour correction from scratch including the blast frames.
I think though, that if I do it, I will work from the BD source, though I will need to re-encode it to a high bitrate 720p first. But that will give me an opportunity to pre-brighten the source and avoid some of the compression being brought up.
