Remove alpha in QC



  • Hi all,

    I m trying to remove an alpha channel coming from Syphon.  I found a trick to do it, (converting it using: image to video- rgb to yuv and - video to image) 
    but its very "expensive" resource wise.  I m after a solution in QC realms, 
    - googeling a bit i found this [https://discussions.apple.com/thread/3756556?start=0&tstart=0](https://discussions.apple.com/thread/3756556?start=0&tstart=0) but this solution is crashing my izzi, 
    - then there is QC NI rgb to YUV patch but also not working for me.. 
    any advice ?
    thanks
    a
