Generate a picture with imagewriter gets somehow skipped in the script

[Yanak]

Hello all,
After getting pushed in a corner out of ideas trying to solve my issue i decide to ask for some help,
I'm simply trying to generate a picture with imagewriter that have his size based on the input video :
Input_Video = colorbars(width = 1920, height = 1080, pixel_type = "rgb32").killaudio()

Make_Pic = BlankClip(length=1, width= Input_Video.width , height= Input_Video.height, color=$FFFFFF) \
.Subtitle("Some Text", align= 1,size=300, text_color=$000000, halo_color=$FF000000) \
.ImageWriter("H:\pic_", 0,-1 , "bmp")

Make_Pic

return Input_Video


Goal is to have a video as input and create only one ( and possibly only once ) a .bmp picture based on the height & width of the input video using imagewriter, then calling again the video input and applying various filters on it.

- Problem is that following the script the creation of the image gets somehow skipped if i try to return the video at the end with either "return Input_Video" or simply calling it with "Input_Video".

- If i don't try to return the video at the end of the script the .bmp picture is created without issues, i tried many variations of this script and simply can't get this working :/

I am probably overlooking something but after spending hours on this trying to get it working and not progressing I resign and ask for help.

Thanks a lot in advance.

PS: in case it matters i'm using avs+x64

Use two scripts. ImageWriter will not write anything if it isn't rendering. With "return Input_Video" you are skipping it. If you absolutely want it in a single clip try Echo() (http://avisynth.nl/index.php/Echo).

I understand now why I was getting a headache trying to solve this...

Echo() does the trick perfectly on a first quick test done.

Thank you very much for the help.
