Blu Ray PAL-NTSC Transcode/Encode

Trying to get a 60hz Blu Ray for Festival in the US from a 1920x1080 25p.


The straight-up PAL encode in Compressor send to Toast 10 Pro Authoring w/ HD Plug-In (re-encode never) burn on to the external LaCie (Pioneer!!) BD Drive works like a charm (A little bit of weird Toast Interlacing going on don't know why, but it is MUCH better than the SD cripe compressor usually puts out).


But when I try changing the frame rate to 29.97 things start to go amiss. Final result is uncanny motion blur, especially in shots with a lot of movement - almost as if the fields were getting all messed up. The only thing I touched in Frame Controls was of course the Rate Conversion, set to BEST.


These are the encode settings: (note 66.15 MB is only about a 30 sec test sample I tried - whole 70 minute doc is more like 8.9 gigs)

Any ideas?? Maybe I can just get a US Blu Ray player at B&H and use it for the Festival (not sony) that will play my video at 50hz - Probably the easiest solution, right? I'm not paying a post house 2 grand, no way.

Are you sure you need at 29.97fps bluray for the festival? Alot of HD systems are framerate agnostic. Check to make sure that you need 29.97 fps from the festival.


That said, the best solution is to use cinema tools to conform your qt to 23.98 fps. this will slow down your qt a very slight amount and shouldn't be noticeable. then most any system will add pulldown to 29.97 if necessary.
