Ive spent hours trying to figure this out 
Im attempting to cue a movie back to frame 1 from a keyboard CHOP, the movie is locked to timeline (for rotation purposes) and hence parameters are greyed out. Any ideas of how to solve this would be great.
Why does the movie need to be locked to timeline? What do you mean āFor rotation purposesā?
The movie is a 180 degree dome clip which rotates 360 degrees in 6764 frames to intergrate with the clipās animated sun cycle. Actually, this is the clip: vimeo.com/79107880
In that case you could use a Trigger CHOP for example to execute the rotation over 6764 frames rather than locking to timelineā¦Then your reset button could just pulse the trigger again?
Let me know if you need an example.
Thanks,that would be awesome, no luck asyet.
Best

Still cant get this to work. If you do have a moment to make an example that would be fantastic.
Here you go.
The setup is the following
1/A button you click triggers a trigger CHOP
2/The trigger CHOP has an attack length set to the desired duration in seconds
3/The Math CHOP converts the input by making it fit inside of a 0 to 360 range
4/The Math CHOP channel is exported to the rotation of a line in a Transform SOP. Put you would obviously put it elsewhere.
You could do this in other way, but this is pretty easy to set up and track.

I think the fundamental flaw is that you have the movie locked to timeline, so you canāt change the movies frame. If you want to go back to frame 1, you have to force the whole timeline back to frame one. Thatās how locking your movie to timeline works.
More often than not though, you can use Sequential playback with a bit of scripting and triggers, which is what Rurikās example is from the looks.
Thatās incredibly good of you rurik! Thank you.
Jonathan,
I can sympathize with you, I have spent countless hours trying to figure out incredibly simple tasks in TouchDesigner. Hours have turned to days, weeks, and now months; all while trying to maintain some sort of hope that there is a light at the end of the tunnel and not another train.
I come from a live production background so concepts like CHOPs and scripting are new to me. I can figure this stuff out but it really does require a different thought process along the way. The only thing that keeps me going is the incredibly useful help that Iāve received from rurik, elburz, and the awesome Derivative staff.
Donāt be afraid of sounding like a noob, thatās what the beginnerās forum is for. The group as a whole has not publicly laughed at me or told me to get lost (yet) and I am very appreciative of that.
Good luck with your project!
Brain.
Hey Pixel
Donāt despair! The learning curve is not short and soft, but the rewards are great. With enough time spent in TD, and with the help of people on the forum, Iām sure you will be building knowledge very fast.
I agree that simple tasks are not straightforward in TD, but only really when compared to different workflowsā¦If you have to re-build something that was designed in a more layer based/linear approach, doing simple things like cuts and cross fades in TD can seem like a nightmare, but in a sense you get very deep levels of control. It is worth diving in to find that.
Keep on keeping on!
Rurik and I ask each other questions all the time, if its any consolation! The learning never ends.
