Yes, you're right Howard. That expression only works assuming the speed is constant.
If the speed parameter is animated, you would have to find the average speed up until that point (the integrate from start to current, divided by current-start), and use that in place of "timingSpeed" On Tue, Oct 25, 2011 at 2:52 PM, Howard Jones <[email protected]>wrote: > Hi > > Just thought I'd try this but no luck, could be me. > > Howard > > set cut_paste_input [stack 0] > version 6.3 v5 > push $cut_paste_input > add_layer {rgba rgba.beta} > Text { > font /Library/Fonts/Arial.ttf > yjustify center > box {480 270 1440 810} > center {960 540} > name Text1 > selected true > xpos 1073 > ypos 139 > } > set N2114dbf0 [stack 0] > OFXuk.co.thefoundry.time.oflow_v100 { > method Motion > timing Speed > timingFrame 1 > timingSpeed {{curve x16 0.5 x38 3}} > filtering Normal > warpMode Simple > correctLuminance false > automaticShutterTime false > shutterTime 0 > shutterSamples 1 > vectorDetail 0.2 > smoothness 0.5 > blockSize 6 > Tolerances 0 > weightRed 0.3 > weightGreen 0.6 > weightBlue 0.1 > showVectors false > cacheBreaker false > name OFlow > selected true > xpos 1073 > ypos 242 > } > push $N2114dbf0 > NoOp { > name NoOp1 > selected true > xpos 976 > ypos 238 > addUserKnob {20 User} > addUserKnob {7 test l frame R 0 1000} > test {{"(frame-OFlow.first_frame) * OFlow.timingSpeed + > OFlow.first_frame"}} > } > > > ------------------------------ > *From:* Ivan Busquets <[email protected]> > *To:* Nuke user discussion <[email protected]> > *Sent:* Tuesday, 25 October 2011, 19:56 > *Subject:* Re: [Nuke-users] OFlow: Source Frame at the current Frame using > Speed? > > If it's set to speed, something like this should do it: > > (frame-OFlow.first_frame) * OFlow.timingSpeed + OFlow.first_frame > > > On Tue, Oct 25, 2011 at 11:43 AM, David Schnee <[email protected]> wrote: > > ** > Does anyone know how to derive the actual source frames on the current > frame when using the 'Speed' timing method in OFlow?
