Public bug reported: Binary package hint: pitivi
I'm working on a video that I'm rendering to OGG Theora. If the video has any fades (using the video "levels" in the timeline), the rendered video is in the Y444 colorspace (no chroma subsampling). This colorspace isn't as well supported (eg Chromium displays it all crazy), and as PiTiVi doesn't let you choose the colorspace anyway, this is certainly a bug... output should be in I420. If I change the mixer so that there is no fade anywhere in timeline, then output is I420 (same edit, just making this change). You can confirm the colorspace using the `ogginfo` command line tool. For example, video with fade: """ jderose@jgd-ws:~/bzr/whatsnew$ ogginfo whatsnew2.ogv Processing file "whatsnew2.ogv"...
