Fonts get aliased when exporting to Cineon in After Effects

[bc3]

I have no idea what’s going on here, but it looks like I lose the alpha channels and my fonts get all pixelated when i try to export a 10bpc Cineon sequence in After Effects.
Can anyone help?

Check out the settings in Make movie…

Also what kind of fonts are you using postcript, true type?

thanks,
i’m using postscript fonts.
i don’t think that’s the problem though.
we tried all the settings and i think what’s happening is the aphla channel is getting dumped somewhere along the line.
i tried exporting the alpha channel on it’s own and it works perfectly.
is it impossible to embed an alpha channel in a cineon file?

perhaps it’s a matter of premultiplied and non premultiplied???

no, we tried that. thanks though.
come to think of it, we’re not even using fonts… they’re rasterized photoshop layers.
totally weird.

While you can stuff pretty much any kind of data imaginable into to Cineon and DPX files, it might well be that AE won’t write alpha channels into them, and so just wrote the fill without the matte. And since Photoshop will rasterise its type into a blocky fill layer plus an alpha channel with the softer-edged matte, if you don’t premultiply as part of the output process the fill Cineon files on their own will look nasty.

I guess it could also be that AE *is* writing fill and seperate matte into the files but whatever you’re viewing them with is not reading the alpha channel?

i think that’s exactly what the problem is.
thanks.
