I hear ya drew.....1440/1080 25p for pal here don't know for NTSC have to fire up a new project.
Broadcast HD is too compressed anyhow, every watch it on a large 1920/1080 HD screen.
........ moving on with more testing.
Here are 4 more grabs....the 1440 ones are better this time.
1. 1920/1080 25p 35mbps mfx in a 1440/1080 25p project

http://www.hdvunderwater.com/videoclips/4.jpgI suggest you open them in photoshop and zoom in.
All screen grabs come out as 1920/1080 even it the project is set on 1440/1080?
The output mxf file from the 1440/1080 25p or 1920/1080 50i timeline is the exact same size and quality to the original 1920/1080 mxf clip when played outside of Edius

Trying to get screen grabs from player to post but no luck yet.
You can only out put to mxf when in a 1440/1080 timeline but as I said it comes out at 1920/1080 35mbps file and is exact same quality size and even meg size as the original mxf one. It renders out them very quickly about 1.1. The HDV 1920/1080 25mbps m2t ones I rendered out fire up the HDV camera and look near on the same a the original 1920/1080 mxf as well so that could be another way to archive back to mini DV 25mbps tape for a saftey saftey backup even though its 25mbps
I hope version 5 will also have on screen keyframing like Premiere.
