Am i correct that if i bought one of these which i realy like the sound of i would have the same problems editing footage and making good films as i did with my SR12 now sold, i am back to plain old hdv for now.

It depends on what your setup, Martyn.

If you're using FCP, you can convert to an intermediate codec such as ProRes, which will yield large files, but will be manageable on older machines. For PC users cineform does essentially the same thing. There's also a panny program made for the HMC150 that automatically interconverts. Another option on the mac is to use toast.

A promising option that is coming soon is Clipwrap2 which allows 'rewrapping' of AVCHD into generic h264, which apparently is easier to edit. Perhaps someone with a bit more knowledge can pipe in about rewrapping?

Thanks Peter my pc is quad core but it would never edit avchd good enough to make good films without conversion in which case i lost some res from my sold sr12 which was a tempermental cam anyway, the GH1 looks good and is something i may think about in the future.
