HD Video Test Clips and Video Format Conversion


Test clip @ 1280 x 720 (720p) or 1920 x 1080 (1080p) can be downloaded from

http://www.microsoft.com/windows/windowsmedia/musicandvideo/hdvideo/contentshowcase.aspx

The WMV files can be converted to other formats such as YUV using ffmpeg:


The command is
ffmpeg -i test.wmv -s 1920x1088 test.yuv -vframes number

For convertion from yuv422 to yuv420:
ffmpeg -pix_fmt yuv422p -s 704x576 -i 704_576_100f_422.yuv -pix_fmt yuv420p 704_576_100f_420.yuv


If want to convert to avi, use
ffmpeg -s 1920x1088 -i test.yuv -vcodec copy test.avi

If need to convert to a jpeg, for example, yuv2jpeg,
ffmpeg -vframes 1 -i test.264 testvid%d.jpeg

If need to convert from bmp to a yuv 420 / 422, for example, bmp2yuv, or bmp2yuv420, or bmp2yuv422,
ffmpeg -f image2 -s 1600x1200 -vcodec bmp -i 1600x1200.bmp -pix_fmt yuv420p test420.yuv
ffmpeg -f image2 -s 1600x1200 -vcodec bmp -i 1600x1200.bmp -pix_fmt yuv422p test422.yuv
