recompute threshold how does it work?

[Peter Wassink]

because this function can take a lot of time to render i'd like to know how to set it without having to try out numerous combinations!

what do the values mean?
what is the Threshold value (0-100) ?
what is precision (1 - 10000) ?
We cannot meaningfull set them if it is not clear what they mean.

if you have a clear explanation, i think this should also go into a help pop-up

Please use the menu "images > exposure" instead of the animator panel.
The use is more easy (one parameter only), and faster.

The option in the custom panel is from an old script, and was not replaced (bug )

thanks fabrice.
but still i'd like to know, what is the value 1 and what is 100

either way it does nothing

i have a low res (600 X 338) video layer 1641 frames imported into a large project (2048 X 1152)
the video has a number of title cards, which i would like to see turned into single instances.
but neither 3 nor 90, 0 nor 100 does anything ?

trying to run it on the videolayer in its own low-res project didn't change the outcome

I need a developper here. Eric2 ?

I think it maybe us based on my script

what is the Threshold value (0-100) ?

It's a percentage representing the threshold between 2 images.

Example: I set the Threshold value to 2
If Image2 is less different from Image 1 than 2 percent, then it considers Image1 and Image2 are the same images.

what is precision (1 - 10000) ?

The precision in this script is a way to control how it will differentiate the 2 images.
If you set 10000 it will check every pixels of the 2 images ( as it is a George script, this kind of work is slow ).
If you set 1 it will check 1 pixel for every 10000 pixels.

As Fabrice said before, please use the "Images > Exposure > Recompute with threshold" because this one does the same things, but it's not a George script so it will be really faster and more precise.

Zut, I didn't know it. I would have changed this in the Newsletter and the User guide =/
