First frame of movie importing as black with 0-alpha

For some reason, all of my movie textures are importing with a single black frame at the beginning with 0 alpha.

This is a big problem for my project, as it requires that I play multiple videos back to back seamlessly, but instead I’m getting flashes of black whenever a switch happens.

I’d try an uncompressed format, but it’ll be a couple days before I can get new copies of the video files.

Has anybody else experienced this?

Edit: I fixed the issue. I was using h264 for the videos - apparently this has issues. So I converted them to mpeg4 and the lame frame went away.

By the way, I used a free program called “Prism” to convert them - great tool.

Thank’s for the tip !!
i got the same problem, and now i’ll check you solution

Thanks for sharing your find. I’m not working with videos but it’s good to see people sharing information like this!

Miro is an alternative way to get good quality ogg theoras for straight usage in unity

As only ogg theora is supported for playback you optimally take uncompressed movies and then convert them over there.
Do NOT go to mpeg4 / h.264 and alike, cause the double compression has very bad impact on the quality (you normally get very visible blocks even at totally overdriven bitrates, while miro from uncompressed avi gets a multiple times better quality at very low bitrates and filesize

Good stuff to know, thanks for sharing!
