Using BLANKCLIP... How?

[slk001]

I have been trying to create a "custom" BLANKCLIP, but I don't know what to put in for "pixel type". What are the values allowed for this variable? Also, if I use 29.97 or 23.976 as my "fps" values, should the "fps_denominator" value be set to 1?

Something like this:

BlankClip(length=3000, width=720, height=480, fps=23.976, color=$000000)

[slk001]

That doesn't work (I tried leaving out the "pixel type", but I got an AVISYNTH incorrect parameter error).

I tried this:
BLANKCLIP(51,720,480,23.976,1,48000,true,true,$000000)

I just noticed that the document on BLANKCLIP on the AVISYNTH WEB page shows "pixel_type" as an INT, while the documents for V2.06 show it as STRING.

It's supposed to be a string.

Okay,after perusing the source code, it seems that pixel_type must be "RGB32", "RGB24", or "YUY2". It is a STRING variable, so the quotation marks are required.

So, this command:

BLANKCLIP(51,720,480,"YUY2",23.976,1,48000,true,true,$000000)

should create a black 720x480 YUY2 clip that is 51 frames long (along with bogus audio).

If you don't list parameters (like pixel type) you have to call them by their names. Thus length=51, etc ...

I changed that. Thanks!
