Video as an animated texture source.

Hi,

Is it possible to use a video (i.e. AVI or QT) as a texture map in Houdini?

Thanks,

Yes, this is possible. Someone please correct me if this is wrong. You'll have to convert the video to just single frame images first. When plugging in the image file use $F to represent which image of the sequence you want ($F is local variable for the current frame). Or use $F4 for padding of four, $F5 for padding of five, etc. An example is below to give you an idea.

Image sequence for texture:

image0001.png

image0002.png

image0003.png

image0004.png

image0005.png

image...

Example path for Houdini:

$HIP/textures/image$F4.png

Thanks,

I can do that, but was wondering if I can avoid having to convert the video to image sequences.

As far as I know the Texture VOP node supports only single frame image formats. You'll have to convert the video to images first. Any compositing application should handle this or if you don't have access to any you can use ffmpeg, replace the paths and width/height accordingly.

ffmpeg -i foo.avi -r 1 -s WxH -f image2 foo-%04d.png

Thanks, I can batch automate it now.
