That is unfortunate, AVCHD should be a result not a source of editing.
When you consider that some cheap cams are spitting out 5 Mb/s in
1920x1080 AVCHD it makes you wonder if it is even worth watching it.
I would like the possibility of using 1980x1080 but indeed not AVCHD as it is now. Chalaron is right, it is shit on most camera's. And bad on the rest. I use video for motion analyzing, more specific the analyzing of technical skills of rowers. The most important thing is frame by frame analyzing the motion. Looking at single frames you don't want to see smeared pictures lacking detail by compression. So at the moment I still use a DV camera because it does not compress. All AVCHD camera's I have seen do compress. Looking at a single frame is awfull. Nevertheless Cinelerra should be able to work with it. Within some years we will see the technical specs of camera's have improved.
Best regards
