Description:
The video transcoding infrastructure creates Theora versions of uploaded videos in various resolutions and bitrates. Currently version 0.27 of the ffmpeg2theora transcoding tool is used which uses the Theora 1.1 encoder.
Current versions of ffmpeg2theora (0.29) usually include the Theora 1.2 encoder (e.g., http://v2v.cc/~j/ffmpeg2theora/ffmpeg2theora-0.29.linux64.bin). This often creates much nicer looking videos.

360p transcode with ffmpeg2theora 0.29 and Theora 1.2: http://maikmerten.de/theora-test/Lutra_lutra_grooming.ogv.ogv
The change is quite noticeable on the water.
The updated ffmpeg2theora version expects the same commandline arguments and should be a drop-in replacement.
