[Nuke-users] OFlow: Source Frame at the current Frame using Speed?
Does anyone know how to derive the actual source frames on the current frame when using the 'Speed' timing method in OFlow? I'm looking to get a curve to export ascii data of the source frames on the current frame for a range.

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 dav...@tippett.com wrote: ** Does anyone know how to derive the actual source frames on the current frame when using the 'Speed' timing method in OFlow?

Re: [Nuke-users] OFlow: Source Frame at the current Frame using Speed?
Thank you kindly Ivan, this is perfect. I do think it should be included though for any retime tools to return the source frame during 'Speed' timing methods, I'll setup a user tab that does this for ours here.

Hi
Just thought I'd try this but no luck, could be me.

Here, this is what I would do it if speed is not constant:

0, etc, but you get the idea)

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
