Lines without overlay

[tin3tin]

I need to make a red dotted box shaped outline with changing sizes.

I guess I could make an alpha box with a colored border and overlay it on top of the background, but overlay is very slow on longer clips...

So my question is do you know of a way to draw lines directly on the frames without using the slow overlay function?

If you only need it for some of the frames, Overlay with ApplyRange shouldn't be too slow.

I guess I was thinking something along the lines of Mohans Draw lines (http://avisynth.org/vcmohan/ColorIt/DrawLines.html) function. However it only draws greyscale lines and I couldn't get Color line (http://avisynth.org/vcmohan/ColorIt/ColorLine.html) to color the line afterwards.

Loadplugin("Colorit.dll")
B=blankclip(color=0)
drawlines(B,0,50,0,220,220,220,line="join",lval=128,brush=true)
Colorline(last,0,50,5,220,$ff0000)

So the alternative is something like this:

b=colorbars(720,480)#blankclip(color=0)
b
border=4
safex=72
safey=57

f=b.blankclip(last.framecount(),b.width()-safex*2,b.height()-safey*2, color=$000000)
fmask=f.addborders(border,border,border,border,$ffffff)
f=f.addborders(border,border,border,border,$ff0000)
overlay(b,f,safex,safey,mask=fmask,opacity=1)

If you want to do a bunch of scripting, Use Crop with StackHorizontal/StackVertical. You can then place your BlankClip(width=1,height=10,color=$FF00000) and not use overlay. Not sure if it will be faster, but it's worth a shot... Making it into a function that replicates Overlay with opacity=1 would be interesting.

ps fix ur links

Actually drawlines is very close to what I'm after. As I mentioned it's only greyscale, and the sourcecode wasn't available(not that I ever tried to tinker with plugin code before, but that might have been a start. :))
