OGG/OGV colors vertically stretched on video

Hello

I’m trying to encode videos in .OGV (Theora video) on a Mac OS X, using various tools (ffmpeg2theora in command line, the FirefOgg extension for Firefox, VLC’s transcoding wizard, Xiph’s Quicktime plugin, …).

The resulting .OGV video plays nicely in VLC, Opera, Firefox, Chrome.
But in Unity the colors are vertically stretched, as if the color layer of the video was twice as high as the luma (black&white).

See the image of the same .ogv video playback in VLC (which is nice), and in Unity, where the colors have “fallen down” :

Has anyone encountered the same issue ?
What video encoding tool (with which settings/parameters) do you use to encode in .ogv files for Unity ?

Thanks

Well for those who might read this thread and encounter the same issue, good news !

I found this great plug-in for Adobe Premiere / Media Encoder :

It’s free, it’s available for Mac and Windows, it works in the latest Creative Cloud 2015 Adobe softwares, and it makes Theora .OGV that work in Unity :slight_smile: !
