First, - apologies for using article posting to ask a question - I cannot seem to attach pictures to questions.

Using the latest BT, on Win XP SP3. Tying to export single-layer show containing particles. However, the exported movies does not match the view in the BT show windows.

the view in the BT show is what I am trying to achieve but when I export the show I get the output shown below, it shows up as solid white discs, totally unlike the show

I have tried different codecs, all the different output types (software, shader, hardware etc) but they all show up the same. Any suggestions as to how I should export a particle show would be welcome. I have tried other layers and they work fine.

2 ideas:

Are you sure HARDWARE AA: MAKE SCREENGRABS doesn't work?

Maybe you are exporting with transparency info. Try exporting without transparency.

Exporting without transparency worked - thank you.

Could you explain please why this happened? Sometimes I need the transparency. Some shows I import into Vegas and so would use the transparency.

Thank you.

It's about alpha compositing. For maximum quality BluffTitler does not premultiply the alpha channel. Some players (including WMP) expect premultiplied alpha or ignore the alpha channel altogether.
