Looks to me like the thumbnail is being rendered in 8 bit, and the canvas is rendering in float? (I didn't think there was a 16 bit rendering format in there, right?). Looks like massive wrap-around in the canvas. Does your plugin support floating-point software rendering? This is correct. The small preview is always 8 bit. If your filter is software only, then you will only ever get 32-bit per channel floating point data, even if the project is set to 16-bits per channel. The reason is that to do anything with 16-bit floats, you have to convert them to 32-bit floats anyway, so we just do it for you. However, if your plugin is running a fragment program, then the fragment program will get 16-bit floating point data in this case. Of course, you shouldn't have to do anything special to your fragment program to handle the 16-bit case. It should just work. (Well, with the exception of bilinear interpolation which works on some cards at 16-bit and not others, but this doesn't look like that issue.) I think it's a bug in your TIFF loader. Micah told me he was in an 8 bit project, and everything worked fine with an 8 bit version of the TIFF file. Switching to the 16 version caused the problem.

If the file being exported is just a copy or an edit based on only one clip then the metadata will copy through. Otherwise, not. Reference shouldn't make a difference, but I can't recall whether I have tried that case. The picture gets a little bit clearer every day. But here the next one ;-) What will happen with the QT metadata if a file is rendered or exported from FCP as referenced file? No, today the metadata is not indexed by Spotlight. We're working on enabling this in the long term, but turning on universal metadata indexing introduces performance challenges that need to be addressed. Many thanks for the detailed answer (and thanks again Wes for the link), The reason I was asking is where - if at all - these data are visible to the user within FCP. But that now has been answered. The next question I had "propagate into edited sequences" is answered as well. Another question is, if I would modify the metadata within the current limitations are they searchable by a Spotlight search (includes Xsan search in 10.5)?

When I drop a layer into the a image well, I still get the image/clip, but after having it running for a while, Motion stales when I try to remove the plugins from the layers ad it takes forever for Motion to came back to life. This does not happen, when I apply an image or a clip directly from the media tab to an image well. OK, I have found that the problem exists when you place a Layer Group into the image well. If you use a Layer Group it crashes. If I use a single source layer ( with or without filters ) it works fine. I have placed an example Generator and source at <www.cidertank.com/TESTDRIVE.zip> . This demonstrates the behavior I am speaking of. If you experience it as well I will report as a bug. On May 22, 2007, at 10:04 AM, David Farmer wrote: I am using FxPlug SDK 1.2 and Motion3.
