Re: [Nuke-users] OFlow: Source Frame at the current Frame using Speed?

[Ivan Busquets]

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"

Re: [Nuke-users] OFlow: Source Frame at the current Frame using Speed?

[David Schnee]

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.


Cheers,

[Nuke-users] OFlow: Source Frame at the current Frame using Speed?

[David Schnee]

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.
