Hi,

It depends on the way you creating the mp4.

Usually there are two ways.

One way is to make it with splitted frame which has color part and gray part for transparency.

Another is with chromakey background.

You should find lots of samples about transparent video.

Hi,

The mp4 file doesn't have the channel for transparency unlike mov format.

So you have to make mp4 with splitted frame or chromakey background and have to use opengl shader when drawing it.

You should find chromakey video sample in our sdk's sample codes.

Thanks
