Just read about this today.

"AVCHD UpShift is the answer for the AVC editing blues. This stand alone AVC file conversion application will allow you to convert your AVCHD clips to high bitrate MPEG files able to be edited on any MPEG2 capable NLE."

IMHO it is nosense intermediating avc files by 50mbit mpeg2 long gop...and after load it again in a passage of NLE...absurd!

first beacause avc NLE of sw like PS12 or Edius 4.6 (just to do an example) work fine.

second beacuse if you want an intermediate file to load for example in premiere CS3 it is better to use, at least, only high data rate (>100mbit) and only spatial compression (intra) or better a loseless intermediate avi...

I agree. A usual one-step (before outputting)transcoding via either ProRes or AIC at 100+ Mbps will be a lot easier on most systems and would result in less generation losses as well when recompressed (outputted) to most widely-used HD playback formats e.g. H.264, WMV, Divx etc.

Editing Mpeg2 in the timeline is invariably less efficient and tax the computer systems more than intermediate codecs do while you can't avoid generation losses anyway as you go from AVCHD to any form of Mpeg2.

Anyone has any idea who may benefit from this, I wonder?
