Hey, I hadn’t realised that, handy!
bnwParticipantDon’t analyse twice. Just render again.
bnwParticipantDo they really centre-cut 4:3, or do they do a 14:9 cutout then letterbox that into 4:3? That’s what happens for 4:3 transmission of 16:9 material over here. The BBC has all the specs for the UK, but it could be different… useful PSD on this page: http://www.bbc.co.uk/commissioning/tvbranding/picturesize.shtml
bnwParticipantYup. Sometimes copying Smoothcam nodes goes a bit wrong, so I’d maybe just disconnect the first, plug in the second, and render again…
bnwParticipantYou can’t do it inside the FileIn with a Quicktime. In a TimeX you could go like “(time % 6) + 30”, or just convert to an image sequence and use the source frame controls to select 30-35, then timing tab in 0, out 9999, repeat mode loop 🙂

We dither down to half float openEXR files then push it to film.
Just curious – do you like to actually dither or just truncate? Wouldn’t have thought quantisation error at the bottom end of a half float image would ever become visible?
bnwParticipantFLM301 covers the Modular keyer including the 3D keyer, in one class, ja.
I’d love to see a still of your shot that Flame worked so well on, if you can… curious as to exactly why Keylight and Primatte couldn’t cut it 🙂
bnwParticipantThe Master keyer in Flame actually uses a polygon shape in 3D colour space, which looks kinda like two wedges back to back. The 3D Keyer in the Modular keyer uses ellipsoids.
If you want to know everything there is to know about Flame’s keyers, take the FLM301 course over at fxphd, Mike explains all of the options in exhaustive detail 🙂
I have somewhere a Shake tree which lets you see how other keyers carve up the RGB cube – Keylight, which usually gets the job done for me, is actually a pretty crude cuboid. Primatte makes all kinds of crazy shapes, the Nuke Primatte has a nice 3D display showing you them 🙂
It seems like Primatte should be able to do the same things as the 3D Keyer, but I find it a pain to control with only colour pots.
bnwParticipantPage 169 in the PDF manual has a list of formats which support reading of tiles. According to that, OpenEXR does, and having worked with the API I shouldn’t think it would be a problem.
bnwParticipantUnfortunately what you probably really want is a Smoke 🙂 But I’d be interested to hear people’s experiences finishing in desktop compositors too… I’ve had to edit things together in Shake before and it just is not fun.
bnwParticipantTres bon!:) 🙂
bnwParticipantThat’s beautiful. I’ve always been curious about how good defocus like that is done… are there any papers or algorithms published or did you have to start from scratch?
bnwParticipantRendering from the command line renders all your FileOut nodes unless they’re ignored.
bnwParticipantJust open Terminal and type the render commands with semicolons inbetween, like: “shake -exec foo.shk; shake -exec bar.shk”. When the first shake finishes the second with begin.
