site_archiver(a)lists.apple.com Delivered-To: Pro-apps-dev(a)lists.apple.com Hello, I'm trying to read custom parameter value data from a Motion xml file. Does anybody know how custom data is encoded and how it can be decoded? Thanks, Eberhard Ammelt, Pixlock _______________________________________________ Do not post admin requests to the list.

A customer has applied a time remap to a clip in FCP 6, which shows in the sequence XML as 80.8163%. If I import the XML into FCP 6 and check the clip, the Change Speed dialog shows 80.82%. But in FCP 7 it becomes 81.22%. If I export the XML again from FCP 7, the value in the XML is 81%. Just a consequence of the Change Speed area being rewritten between versions? As an aside, is there ever a situation when the time remapped value is negative? It's not used for reversed clips as there's a separate reverse parameter for that.

So far it saves this data into a file in the user space and keeps the file name in a custom parameter. Unfortunately, with this approach one gets into trouble, when the user duplicates an effect instance. Then, both instances share the same data file, and it happens that one effect instance falsely loads the data that was created by the other instance. I'm not aware of a way in fxplug to find out if an effect instance was created by duplication. As an alternative, I'm considering to put the whole data into the custom parameter, but I'm concerned about possible side effects when the FCP project file gets very big. However, according to my tests, opening and saving an FCP project with 1 - 10 MB works quite well. Any suggestions regarding the best strategy for handling big custom data? I don't anticipate that causing any problems. There are other developers who store more data than that in their plugins, and which get saved to disk. It's not ideal, but there are some situations where there's no other way, and this is one of them. This email sent to site_archiver(a)lists.apple.com

They kind of go together in my mind -- if you know the anchor point and scale, then you could correctly composite the image within an FxPlug, which is what I'm trying to do... Ben, I don't believe there's a way to do what you want. Please file a bug about it: This email sent to site_archiver(a)lists.apple.com

But if the Anchor Point is adjusted, the image will move, but layerOffsetX and Y will remain fixed. I either need a way to access the Anchor Point of an FxImage or I need to be able to figure out its exact global position. I guess one way to think about it is that I need FxLayerInfoAPI to be more robust -- I need to be able to do getLayerGlobalOffsetX::: for FxImage inputs, not just the layer the effect is applied to. If I'm overlooking a way to get the absolute position of an Image parameter, please let me know! Ben, I don't believe there's a way to do what you want.
