Transparancy support in AVI codec?

[lnetzel]

I don't mean an uncompressed AVI is specifically bulid up of BMP's cause I have no idea how AVIs work in technical detail but in PAL there are 25 images per second and the least compressed format when it comes to windows and images are BMP, right? so I figured an avi is bulit up of images like BMPs maybe... Why I draw this conclusion is because someone once told me that the MJPEG codec uses JPEG pictures... so... the comparision to BMP is logical for me.. but maybe that's not how I am supposed to look at an avi...

Anyways... then I figured... If it's possible to make a codec that will "glue" together PNG pictures with the Alpha channel thingy, would'nt it be possible to make an AVI with a transperant background then so you wouldn't have have to mask certain colors and stuff?

For example if you export a 3d animation from 3ds MAX with a codec like this you would save time a troubles with the masking...

I noticed this when I imported a tranarent GIF animation to see if it worked and it did.. but I'm not gonan use GIF to do these things...

Okay, so none of you in here OR in the Advanced Conversio have bothered to answer this... so I had to find out for my self in othe forums .. and I almost don't feel liek sharing this with you all but ... since I'm a nice guy.

If you save an uncompressed AVI there are support in some applications so save the alpha channel like in Vegas Video for example.. so no codec needed for this!
