Overlay swapping

[j2c]

I'm wondering if there's a way to change the overlay to a different image every 30 seconds(back and forth). Heres my script right now(overlays come on at the same time)

source = "test.avi"
lo1 = .3
lo2 = .2


src = DirectShowSource(source)

logo1 = ImageReader("logo1.png", 0, 0, 1, true).BilinearResize(src.Width() - 12,src.Width() / 2 - 12)
x1 = src.Width() / 2 - logo1.Width() / 2
y1 = src.Height() / 2 - logo1.Height() / 2

logo2 = ImageReader("logo2.png", 0, 0, 1, true).BilinearResize(src.Width() , src.Height())

Overlay(src, logo1, x1, y1, mask=logo1, opacity=lo1)
#Overlay(logo2, 0, 0, mask=logo2, opacity=lo2)

Simple, rather untested:
source = "test.avi"
lo1 = .3
lo2 = .2


src = DirectShowSource(source)

logo1 = ImageReader("logo1.png", 0, 0, 1, true).BilinearResize(src.Width() - 12,src.Width() / 2 - 12)
x1 = src.Width() / 2 - logo1.Width() / 2
y1 = src.Height() / 2 - logo1.Height() / 2

logo2 = ImageReader("logo2.png", 0, 0, 1, true).BilinearResize(src.Width() , src.Height())

ov1 = Overlay(src, logo1, x1, y1, mask=logo1, opacity=lo1)
ov2 = Overlay(logo2, 0, 0, mask=logo2, opacity=lo2)
ConditionalFilter(ov1, ov1, ov2, "current_frame % 250", "<", "125")

"250" is the number of frames between a logo shift back and forth. "125" is the number of frames the first logo should be shown.

If I made this correct, the thing above should show logo 1 in frame 0->124 and logo 2 in frame 125->249 and then switch back to logo 1 and so on.

or, more simple
source = ...
logo1 = ...
logo2 = ...

switchtime = 30 # in seconds

slength=framecount(source)
srate=framerate(source)

logo = \
interleave(logo1,logo2).loop().assumefps(1) \
.changefps(srate*switchtime).assumefps(srate).trim(0,slength)

# ... now simply overlay "logo"

complete it by yourself ;)

source = "test.avi"
lo1 = .3
lo2 = .2



src = DirectShowSource(source)

logo1 = ImageReader("logo1.png", 0, 0, 1, true).BilinearResize(src.Width() - 12,src.Width() / 2 - 12)
x1 = src.Width() / 2 - logo1.Width() / 2
y1 = src.Height() / 2 - logo1.Height() / 2

logo2 = ImageReader("logo2.png", 0, 0, 1, true).BilinearResize(src.Width() , src.Height())
x2 = src.Width() / 2 - logo2.Width() / 2
y2 = src.Height() / 2 - logo2.Height() / 2

ov1 = Overlay(src, logo1, x1, y1, mask=logo1, opacity=lo1)
ov2 = Overlay(src, logo2, 0, 0, mask=logo2, opacity=lo2)


ConditionalFilter(ov1, ov1, ov2, "current_frame % 1800", "<", "900")This one worked with my different opacity & position settings. Is there a way to change the frames used dynamically like in Didée's example to use in ConditionalFilter?

what exactly do you mean by change the frames used dynamically?

btw if you don't understand the % symol, here (http://www.intellidimension.com/default.rsp?topic=/pages/rdfgateway/reference/script/mod.rsp) is an explaination

"current_frame % 1800", "<", "900"

[Vectrangle]

"current_frame % "+string(framerate*60), "<", string(framerate*30)

thanks everyone! :D

Vectrangle - i'll take a look at the ScriptFunctions page ;)
