site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com Theory: One way to not make a plugin to show up in Motion 4 would be to compile a 32/64-bit universal version where the 32-bit version is compiled against the 1.2.5 SDK and the 64-bit version against the 2.0 SDK. Than make the plugin return a null in the -initWithAPIManager: method for the 32-bit version or include the full 32-bit plugin. (probably complicated to do) I was trying to do that, but than I decided not to go in that direction. I wound up creating two separate versions where the 64-bit ones are even in a new folder in thd effects menu with a added (64-bit) to the folded name. That way I am free from the old SDK and go full speed ahead using thd new features of the 2.0 SDK without worrying about backwards compatibility. The 32-bit plugin bins still show up in Motion 5, but nog the plugins. I dont know right how my 64-bit plugins show up in Motion 4.

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com Also, I doubt that it will accept a 65k wide texture. Most cards today have a limit of either 4k or 8k for the width of a texture. You may need to either upload multiple 1D textures or upload a 2D texture and do some math to choose the correct sample.

I often don't mix and match texture targets like that myself - you could also make a 65Kx1 RECT texture and probably get the same result.

Close. but no cigar. But at least it helps, kinda like. I'm also hovering around this issue. Full native FxPlug support for FCP X would solve this problem and most other problems right away.

I don't know if this will work for your plug-ins or not, as I don't know how you're using and calculating those sorts of things. I urge you to try out how it works and let us know if there's a more effective way we could be doing things. And again, the quicker you tell us, the better. Any way to get the frame rate of the underlying footage? And Duration? Not currently. I believe that has always been the case, though, hasn't it? Is there any way to get accurate clock time from all of this? Normally you can divide frames by FPS to get a time in seconds. But suppose I have a moef that's 10 seconds long and I apply it on a 1-second clip. Motion will fudge all the timing numbers so keyframes and relative position in the clip basically work out right, but if I try to calculate absolute times, it will appear to my effect as though 10 seconds have elapsed, instead of 1. If the effect relies on clock time, everything is going to move 10x faster than it should. There are lots of effects that work this way -- flicker, camera shake, simulated clouds, etc. This could be a show-stopper problem for a lot of people. At this time, I don't think there's a way to do what you want. It will be time-stretched. Please file a bug. Ouch, that's pretty bad. Many of our effects will be broken by this problem. I've filed a bug -- hopefully a fix will be available soon. We did discover a partial workaround -- if you use markers to make a loop in your Motion project, frame numbers won't be remapped within the loop. So as long as your loop is longer than the clip in FCP, it sort of works (though the framerate may still be long). Unfortunately, if you use this workaround you can't determine percentage through the clip anymore. This email sent to chv(a)chv-electronics.de This email sent to site_archiver(a)lists.apple.com

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com Hi Christoph, Thanks for the tip! I just added it, but I still get the black screen. After reading through some other postings, it occurred to me to check the pixel type. It looks as if the image is 16bit Floats. I wonder if this is a potential problem, as I am providing 32-bit float values in my LUT. The rounding inconsistencies alone would cause the LUT to be useless.. :( Still, I guess I am wondering if I am setting this up properly. Should I supply a 16-bit Integer LUT as a texture? -- this is ideal, as that is what I started with. bob..
