Blu-ray data levels – 24 gig ?
I have a lacie blu-ray burner and from my experience on dvd studio pro, you can get near the project level of data on the disc – however, every time I burn blu-ray I can’t be sure how much to trust encores project build measurements – I’m now guessing that 24 gig of data is actually 25 gigs-worth of disc. If I go to 25 gig – it transcodes for hours then at the end says there’s too much data – what’s the optimum level of data for a 35 gig disc?

The problem is marketing gigabytes (decimal) vs. actual gigabytes (binary). Here is an explanation:

A Blu-ray disc will hold 25 decimal gigabytes per layer, or about 23.84 gigabytes.

Thanks – I knew there was something going on – I’ll now load to 23.5 for safety.
I notice that any slow mo becomes very stuttery – is this the long-gop mpeg 4 problem ? Is there a solution ?
Thanks again

….and also whilst I have your attention:
sometimes Encore gets almost to the end of a long blu-ray transcode and just quits. All the transcoding has been done (hours) – but when I re-open the project it starts transcoding all over again. In DVD studio Pro you can tell it to find the transcodes – so how do you do that with encore – is is it too plain dumb? Or would toast pick up the transcodes and burn there ?
