Just a little tip for faster AVCHD editing in Premiere Pro
It might be an obvious one but if you haven't tried it - TRY IT!
Click the drop down options in the top right of the Program Monitor and/or Source Monitor and select Draft Quality instead of High Quality
You can also right click the video in either panel to get the option.
Simple thing makes a massive difference with playback speed.
Now that all my cameras shoot AVCHD I am finiding it really important to speed up my work flow in any way I can. Hope this helps some of you.
