irm Posted March 19, 2006 Share Posted March 19, 2006 I have a channel that is either 0 or 1. I'd like to derive another channel that, during any period where the input's value is 1, returns the frame number at which the input channel next changes back to zero. So I'm looking for behavior like some sort of event CHOP but with the ability to look one event ahead. I'm not very familiar with CHOPs, so I don't even know whether this is possible. Any suggestions or ideas would be very welcome. Thanks, Ian Quote Link to comment Share on other sites More sharing options...
edward Posted March 20, 2006 Share Posted March 20, 2006 Can you just figure out the event changes and shift the resulting data? Quote Link to comment Share on other sites More sharing options...
irm Posted March 20, 2006 Author Share Posted March 20, 2006 Can you just figure out the event changes and shift the resulting data? 25757[/snapback] The events occur at varying times and for varying periods, so this would mean shifting the channel a different amount for each period where the input value is 1. Do you mean it's possible to do this by accessing a list of events, eg. querying what frame number an event CHOP's fourth event occurs on? If so, great, this would solve the problem, but I don't know how to perform such a query; could you explain? If you mean finding a procedural solution or shifting the channel by hand, unfortunately these are not possible because the function is to be applied to a large amount of arbitrary data. Thanks for your reply. Quote Link to comment Share on other sites More sharing options...
Jason Posted March 20, 2006 Share Posted March 20, 2006 You might be interested in the Logic CHOP for this somehow. Have you looked at that? Quote Link to comment Share on other sites More sharing options...
puma.snyder Posted March 20, 2006 Share Posted March 20, 2006 If I understood you right, this should work as expected. If you want to look further ahead, change the post add value in the math1 chop. Hope this gets you started Achim next2.hipnc Quote Link to comment Share on other sites More sharing options...

It was the Split CHOP that solved the part I was stuck on. Thanks very much! Quote Link to comment Share on other sites More sharing options...
