Hi I’m trying to get the start frame and end frame numbers from a clip that my filter is working on, on the timeline. double start = [timingApi startTimeForEffect:self]; double duration = [timingApi durationForEffect:self]; However start always gives the start with reference to the timeline and doesn’t handle trimmed start. Just in case my explanation is not clear; say I start a new project, add a 100 frame clip to the timeline and trim the first 20 frames. The code above gives a start of 0 and duration 80. I need to know that the start is now at frame 20. There was discussion about this feature on the ML back in 2009, see http://lists.apple.com/archives/pro-apps-dev/2009/Oct/msg00005.html I guess it could have been implemented in FxTimingAPI_v3 but I can’t find the reference documentation for this. The FxPlug SDK documentation (https://developer.apple.com/library/mac/documentation/AppleApplications/Conc...) has many protocols that are not documented/linked. thanks in advance Lyndon Hill _______________________________________________ Do not post admin requests to the list.
