Hi, new user to PDR11. Finished my first project, a 1:38 hours blu-ray disk. PDR did a great job and I was a little disappointed that I couldn't burn the full 1080 60p, burn would just allow 60i. The previously produced m2ts file is noticeably better for viewing fast motion. So that's a little introduction to what I'm doing.

There is not an offical 1080 60p format for Bluray.

Here is is list to the supported BluRay formats.

The only 1080 Progressive is 24 fps.

Thanks for the link. I'll try 1280×720 60p (16:9) format next. Actually my camera is DV tape so it doesn't take full 1080 resolution, it's the standard NTSC 525 line 60i. I did try authoring the m2ts file from the 60p into 24P and it wasn't a good match-up. It's difficult to go from a 60p rendering into 24p - the motion is "flickery." I found out the reason below.

To get around showing 24 frame film on TVs, I read where the TV industry did a 3:2 pulldown to convert film movies to 60i NTSC broadcast TV. They'd convert 1 film frame into 3 TV video fields and then the next film frame into 2 TV fields and get 24 frames x an average 2.5 fields = exactly 60 interlaced frames for TV. For film media that was filmed only for TV broadcast they'd shoot the film at 30 fps and avoid the 3:2 pulldown altogether because 3:2 can show some motion artifacts.

Taking a NTSC originated avi file (firewire'd from the camera) like mine, rendering it into 60p, and then finally authoring into 24p, PDR wouldn't have any knowledge about the source and a need for 3:2 pulldown. Anyway, the 60p m2ts file that powerdirector did render for my old camera is really beautiful for the way it maintains and actually improves my camera's video (especially with fast motion). I just wish blu-ray would support do the full 1080 x 1920 at 60p so I could see the same result on HDTV (with fast motion) that I see when I play the m2ts on my laptop with a player like powerdvd!

Thanks, Gordon Gordon
