Sorry was a bit unclear, I am using AVCHD through log and transfer converting to prores, i am not exporting back to avchd, i am simply asking which method is best my test export with was 189 mb in size (7 min long) looked good, but when for example one of the actors jumps from the house to the ground in the playback viewer his fall was seemless and smooth, after export it was a little blurry. trailish to sound blunt. I just want to know the best way to export in general. Im new to flash drive cameras, i was using dv tape based ones before.
