Best 720/60p to Blu Ray workflow
on Mar 3, 2010 at 5:30:53 pm

I have shot a good amount of 720/60p footage with my EX3 and have taken those projects to Blu Ray disc by exporting to a ProRes or ProResHQ file and letting the software (Encore or Toast) do the transcode for Blu Ray disc. I shot in 60p because most of the footage is fast moving such as sports and it has looked great in the ProRes format once exported.

Unfortunately, today I read that the Blu Ray software is actually doing a transcode to a different frame rate or is upres'ing to 1080 because 1080/60p or 720/24p is supported whereas 720/60p is not supported by the Blu Ray spec (for Blu Ray Video).

Although I'm fairly happy with the results (and I'm puzzled as to why??), I'm thinking that this can't be the optimal way to handle the 720/60p footage and I'd like to know how others are handling their 720/60p footage in getting it to Blu Ray disc? Obviously I want to try to retain as much info as possible while burning the highest quality Blu Ray Video.

One disclaimer, I have not tried the export to Blu Ray through FCP's Share feature although I may be trying it now...

Whatever your process is, please share! Thank you.

Thanks Craig. And that's what I get for looking at the Blu Ray spec on a chart on Wikipedia. :)

It looks like someone didn't copy their (Blu-ray disc) White papers correctly.
