Hi – thanks for that Danny. You said:

“If you were talking about 960 lines this used to be DVCPROHD 720p50, this is native 960x720pixel with anamorph pixels”.

I meant that the chip had 965 pixels – so 1920 is twice the upscale and in my naivety I’m imagining that data multiplied or divided by whole numbers, or fractions that are not too radically different (halves, quarters, thirds etc) will produce a new set of data that’s ‘truer’ to the original.

On the projector I’ve discovered through testing that I definitely get greater detail from 1920 out of a 1280 projector than 1280 (given that the data from the original 965 pixel chip requires a multiple of around 1.25 to upscale – rather than the whole number).

Anyway – take all of that with a large pinch of salt because I’m probably making things up.

So what’s the frame rate to go for in the end 23.98 or 29.97 given the greater amount of data to generate for 29.97 and the data to lose for 23.98?

For us over in 50 cycle land it’s a lot less pain – we don’t get the choice (except if we mess around with going down to 24fps – then we just buy the slowdown as a poetic addition)

I know that this post has been answered – but a question – why not simply make a 60i blu-ray disc?

I have a project that is 50i originated that somehow has to work with American blu-ray. The images began on P2 and therefore were only 965 pixels in the beginning – they were up-rezzed in FCP to 1440, then 50i’d and therefore became 540 lines of resolution by being interlaced- it’s all downward. So I wanted to avoid yet another step down to progressive and 23.98.

If I go back to the original file and reset the timeline – what should it be to be the best for blu-ray in the states? 30 fps with in 60i interlace or 23.98 ? And then there’s 29.97 and 59.94……

This has to play back via a 1280 x 720 projector (unfortunately) – so should I not even go to 1440/1920?

When doing this stuff in Euro mode I’ve discovered that if I work at 1440/1920 instead of 1280 the projected picture always looks better….

Can anyone help?

….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 ?

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

Sorry Adam – this is no answer to you but I have the same problem – 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 ?

I bet you’re right on the idea of a blu ray file – though I did hear that Vob’s would work on some tv’s – I was just being hopeful. In terms of HD playback, with other Gop oriented compression systems there’s a good chance of fast enough data throughput.

My point was not to disenfranchise the earning power of a huge consortium. My thinking was in the vein of trying to be imaginative about what piece of kit can be used in which situation. We are wedded currently to the developments of the likes of sony, dalsa, thomson, philips, pioneer, panasonic etc al (and long may they do what they do best), yet along comes a small company like red and says ‘hold on, there’s another way’. As it happens I got quite excited about the idea of using something with no moving parts and consequently set off on a technically based search for a solution – that’s all.

I wasn’t remotely interested in manufacturing a blu ray disc virtual or not – I was interested in whether or not it is technically possible to display hd images on a plasma display directly from such a small source.

In terms of whether cards can deliver moving pictures, I’ve already managed to do that so I know it works – and if one of us has managed it you can bet your life it’s happening all over the place. It’s just the future.

Again – I have no intent on breaking licenses or anything remotely of that order – the technical possibility is what is interesting to me.

So, happily I went off and tried a solution suggested by Warren- that is, getting a Panasonic SW-5583 Blu-Ray – of course these units are not available in the UK yet !!!

Has anyone tried the LG GGW-H20L Internal on a MAC – this one I can get easily and cheaply

Thank you for everyone that’s already replied.
