A LUT itself is not linear or non-linear, it's just a transformation. But a LUT is made with input and output color spaces in mind, so you'll have to get your pixels into that space manually.   For example, a .cube file is usually not intended to be applied in linear space. If your .cube was intended for log space, you have to convert from linear to log before applying the LUT, perhaps using the Cineon Converter, Color Profile Converter, OpenColorIO plug-in, or some other method. ...

You might have to write your own script to make this setup for you.   Or another tactic I've used is to make one comp with all these animations on one timeline, lined up one after the other, maybe with some gaps in between. You use keyframes to change the colors and text, time remapping to repeat animations, etc. You can see all the animations in one place and make global changes easily.   For output, you make a comp for each person that has your main comp with the in point shifted. ...

If you have a bunch of machines, some of them will sooner or later develop various issues and the only guaranteed way to get things working again is to be able to wipe them clean with a fresh OS and re-install everything from scratch.   It's also helpful to have an image of a known working system with various softwares installed and configurations set so you can get back to a known working state more quickly.   Finally, as this thread makes clear, you should not let machines update themselves. When there's an update, run it on one machine and test before updating the others. Even then you may miss something and still need the ability to bounce back to a working state.   Our studio completely relies on aerender and we would be in a bad state if all our machines had updated themselves and broken it. ...

The Cryptomatte data is all stored in a custom parameter, which is not accessible via scripting, unfortunately. If you import an EXR as a Composition, the Cryptomatte plug-in will be set up for you, but only one copy and without anything selected. The set up is done using the OpenEXR C++ plug-in, and only a plug-in like that could get the info from the EXR sequence and set up a bunch of Cryptomatte instances for you.   In general, making a matte for each individual object is an un-Cryptomatte thing to do. The Cryptomatte workflow is supposed to be that you click on a bunch of objects to make a matte for a specific purpose. You could have a file with thousands of objects and you probably don't want a separate matte for each one. ... View more

The OpenEXR spec says the image should be premultiplied, and that is assumed to mean premutiplied over black. When you premultiply over black and have 16- or 32-bit floating point pixels, you can generally convert back to straight without any noticeable loss, as After Effects does because it works with straight internally. Film compositing programs like Nuke are premultipled internally, so EXRs work smoothly there.   The advantage of straight alpha is you can recover RGB values in your transparent areas just by filling in the alpha. Or you can use the alpha for some completely different purpose like the guys above were trying to do.   The advantage of premultiplied alpha is if you have RGB values in an area with 0.0 alpha, this composites as a glow or a light ray—a purely additive element that doesn't block the background. If your 3D renderer can create glows, this is how they'll probably turn out, and you can't composite them properly in a program like After Effects without resorting to some tricks.   OpenEXR has some cool samples of non-zero RGB over zero Alpha. Try importing them into After Effects and then try setting alpha interpretation to Ignore.   ... View more

Right, but EXR was created for use in 3D rendering, where alpha means transparency and renders are premultiplied. Premultiplied is in the spec.   I'm glad you're able to write a straight alpha and use it this way, but it was not the intention of EXR. It could also be a little risky because you're not guaranteed to get good RGB pixels in areas where the alpha is 0, but if it's working for you I'm glad.   If you think EXRs should support straight alpha, you can make your case to the steering committee.     ... View more

This option is intentionally left hidden because the EXR spec calls for files to be premultiplied. There is no flag in an EXR to mark it as straight.   Some people wanted to put a straight alpha in an EXR for whatever reason, so this allows them to do it, but they are responsible for dealing with whatever issues it may cause down the line. ...

OK, I have the correct answer for you, courtesy friends at Adobe.   Quit AE and edit the Prefs file called something like Adobe After Effects 17.7 Prefs-indep-general.txt. In the ["Misc Section"] you want to have this:   "Allow writing straight alpha into EXR" = 01   You may already have it there, with the value set to 00.   You can also run a script like this:   var section = "Misc Section"; var pref = "Allow writing straight alpha into EXR"; var type = PREFType.PREF_Type_MACHINE_INDEPENDENT; if(app.preferences.havePref(section, pref, type)) { if(app.preferences.getPrefAsBool(section, pref, type)) { alert("EXR straight alpha pref already set to TRUE."); } else { alert("EXR straight alpha pref was set to FALSE. Setting to TRUE."); app.preferences.savePrefAsBool(section, pref, true, type); } } else { alert("EXR straight alpha pref not set. Setting to TRUE."); app.preferences.savePrefAsBool(section, pref, true, type); }     ... View more
