Hi Todd

So is Premiere = guessing what the the alpha is for each import, or is it forced for a = specific format. Eg. the TIFF sequence i have now is read as Straight = and Premiere always read TIFF as straight even if it is = Premultiplied?

It really needs the same interpret footage dialog as = AE :-)

In Premiere Pro, the handling of straight versus = premultiplied channels is specific to each importer; there is no general = way to specify this for the whole = application.

Please submit a feature request to the Premiere = Pro team.

Subject: [AE] Premiere Pro premultiplied alpha = question

Hi

I know this is a bit OT but cant find a good answer to this in the = manual or anywhere online :-(

Where can i set what the alpha should be interpreted to in = Premiere Pro?

there is no option in the interpret dialog like in AE, but the = manual says that premiere handles both straight and premulitiplied, but = no option to set it if it is wrong?

The only option i have found to correct it is use the Remove Matte = effect, but i hope that isnt the correct way to do it = :-(
