What is the error here?

[OldNick]

I copied a script text that someone had put up to the forum. I opened Track FX and the Video processor. There is a text box there and I pasted the copied script text into that. I then asked to Save Preset. Nothing showed.

When I tried to use the preset, I was told
"Error compiling code

unknown error, no code?

Save bad code?"

Have I taken a wrong path, or is there something in the script? The poster said it worked and others seemed to agree.

Here is the text
//RGB White Balance Colour Grading
src=0;
//@param2:red 'red' 0 -0.1 0.1
//@param4:green 'green' 0 -0.1 0.1
//@param6:blue 'blue' 0 -0.1 0.1
//@param8:intensity 'intensity' 1 0 10
input_info(src,w,h) ? ( project_w=w; project_h=h; ); // preserve input dimensions
w>0 ? gfx_blit(src);
gfx_mode=w>0 ? 1 : 0;
gfx_gradrect(0,0,project_w,project_h, red, green, blue, intensity);

Thanks for any help.

I added video processor to a track, pasted this code in verbatim and clicked ctrl+s and it worked FWIW.

I think problem is that he didn't hit Ctrl + S while still in the code window. If you don't actually do that, the video processor does not recognize what you pasted into that area, or if you changed any code of an existing preset.

Yea, that was my hint to try what I did.

AH. OK. I thought that I was supposed to click the little + button next Param and ask to Save Parameter. Sometimes I do find all this a bit .....wild west.

Anyway. Thanks guys. As you say it works.
