But I think we talk of different UIDs. The UID in the XML seems to be the path of the motion template. But what I am after is a way to identify the clip in the XML during running the generator, so I can generate a XML-Workflow to place the rendered output grouped with the generator clip. The generator clip I want to group looks like this: <video name="Filmstro" lane="-1" offset="154154/24000s" ref="r4" duration="7672665/120000s" start="86486400/24000s"> followed by the parameters.

I’m not sure if you have to mark it as a percentage parameter or not, but that should be easy to test out. Otherwise, it only allows the user to move the keyframe in time, but not in value. > That doesn't seem to work. I changed my parameters to go from 0 - 100: [parmsApi addFloatSliderWithName:@"Volume" parmId:kVolumeParamID defaultValue:100.0 parameterMin:0.0 parameterMax:100.0 sliderMin:0.0 sliderMax:100.0 delta:1.0 parmFlags:kFxParameterFlag_DEFAULT]; I also found a checkmark in Motion "Show in Keyframe editor", but that seems to be unrelated for the publish, at least it didn't change the behaviour for me - I re-saved project in motion, removed the clip in FCPX from the timeline and added a new one. Still there is no option in FCPX to expand the keyframe editor to 2-D, as the Compositing / Opacity keyframes do. What did you mean with mark it as percentage? I didn't see an option for that in the docs, and kFxParameterFlag_ have no option. However, it has the opposite flag: kFxParameterFlag_CURVE_EDITOR_HIDDEN. What is the intention of that flag? I tried it anyway, but setting it also made no difference. >> 5) If your generator is not adding images, you shouldn’t be using a generator. That is their sole purpose. Having said that, no, there’s no way to tell that a preview is being rendered vs. a regular render, nor is there a way to tell which preview is being rendered. > > I know I am bending the architecture a bit, but just because I didn't find to add an to be rendered audio clip into the timeline, see above... > But I found out, that adding the information into the motions generator large.png and small.png thumbnails is ok for a start. > >> 6) You can right click next to the parameter’s name to bring up the menu which will allow you to publish the button.

Motion Template key in FCP-X XML for published parameter
by Rainer Standke 19 May '17

19 May '17

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com Hello all, here is a tricky one, I think. I am looking at programmatically putting titles based on a set of Motion-based custom presets - they might be called templates, right? These templates all share a parameter that I believe to control a ‘rig’. I’d like to set that parameter programmatically in the FCP-X XML for each of the templates. However, the keys for that parameter is different in each template. Here is a sample line from the FCP-X XML: <param name="Crop" key="9999/551412442/551412443/551412444/551412548/1/216" value="0 279 0 0”/> The question is, can I manipulate the templates so that the rig uses a specific key in the XML representation? Is there a way to do that in Motion? If not in Motion, can I edit the XML in the .moti file that seems to represent the template? Seems like there is meaning to the sequence of numbers in that key. Looks like the parts between the slashes show up in the .moti file identifying groups, layes, and such. Any hints would greatly be appreciated.
