First thanks Alan

I know the alpha channel does not work because when I bring the avi file into Adobe premier as an overlay it blocka the video track under it. I have tried the render with png file and it works fine. Where I select the codec. When select the output render to be avi type. it gives me a pull down menu to select diff codec. I have not tried HuffYUV since I don’t have it installed. I thought the avi format would be more convenient instead of dealing with hundreds of pictures..

Regards

So I render just the particles in avi format using lagarith lossless codec with the save alpha checked and removed black bg from RGB channels both checked and unchecked and I still don’t get the output avi with alpha channel but a black background. I must be missing something obvious.

Please advise
Thanks

I can check the pI3 ver under Help, but where do I go to check the pIRender ver? I invoked the check updates and nothing came up. Does that mean my pIRender is also up to date?

Thanks

PI 3.0.4.2 runs fine on my PC with Intel i7 & Windows 7 64 bits. The activation window popped once, It was probably due to the update. I clicked activate and everything is fine with my recent project. I don’t have an earlier project to try.
