No, express use AIC, but if u have the prores qt component installed U can use Prores in the timeline and export to it. But during editing u have to render as something else.
AIC does support clips with 720p60. But i cant find anyone who has got the 720p50/60 clips from the HMC-150/151 to work with log and transfer in Final Cut Express. It crashes. All the other formats work.
Does anyone know of a program to convert the 720/60p footage to AIC. I can convert all other formats in toast 9, but it can't handle the 720/60p and I want to shoot some god slo-mo. Thanks
