Скачать или смотреть ffmpeg2theora-0.24 Theora transcoding of Mandelbrot Zoom

This is the result of using ffmpeg2theora-0.24 to transcode a 10 Gigabyte Mandelbrot Zoom raw video to downsample it to 100 megabytes. Artifacts are to be expected.

How this was made:

XaoS 3.2 to render 2374 PNG frames of a slow Mandelbrot zoom of size 1440 x 1080

VirtualDub 1.9.8 used to convert the 2374 frames to a n uncompressed AVI file marp0000raw.avi of size 10 Gigabytes. VDub was used because although png2theora can transcode the PNG frames directly to a Theora video, Google's YouTube renders the resulting video incorrectly.

ffmpeg2theora-0.24.exe marp0000raw.avi --videoquality 3 --optimize -x 1440 -y 1080 --keyint 80 -o marp0000raw_avi_024_vq3.ogv

This video plays Ok in Chromium, Firefox , Media Player Classic, SMPlayer and VLC.
