Newbie question - alpha channel

[AAAron]

Sounds weird. A simple solution would be to render the whole thing as a targa seq instead of an avi. Make sure that the targas are 32bit to get an alpha channel.

Hi, this is a very simple question. I rendered an AVI file from maya with alpha channel. When I import it to After Effect in the composition window it becomes completely transparent. It works fine with still images with alpha channel. What am I doing wrong? I chose the straight-unmatted setting.

AVIs normally cannot contain Alpha channels, so there may be none included and AE is simply interpreting your file in a wrong way (perhaps the header says there is an Alpha and AE inverts it for som reason which makes everything transparent). AFAIK HufYUV is the only non-hardware dependent AVI CoDec that can include Alphas. Your best bet is to simply use image sequences in that case which would be wise anyways - if your Maya render crashes, you don't end up with unusable damaged movie files and only need to render the remaining frames.

hi susantio, i`ve experienced same problem like you at my home. I'm using Maya too, when i rendered into AVI files it became transparent in AE. Then i try to render it using targa sequence and the result is fine. So export it into targa seq. I hope this is helping you.

OT : Susantio, are u indonesian?

Thanks for the explanation. I was just testing something in after effect. For the final thing I will render it as targas.

Marvelet: ya. aku org indo :P
