Where can i get YUV444 & YUV422 raw Video sequences?

[goldenmean]

Hello,
I need some YUV422 and YUV444 raw video sequences for testing ffmpeg encoding to these formats.
I have 420 sequences.

1.)Is there any site where i can download some test sequences(Any Resolution QCIF,CIF,... will do)
2.)Is there any tool using which i can convert the 420 videos i have to YUV422 and YUV444 types?

Any pointers appreciated.

thanks,
-AD.

These might work for you:

As for conversion, I'll leave that to someone more knowledgeable.

AviSynth can convert 4:2:0 (YV12) to 4:2:2 (YUY2):

ConvertToYUY2()
ConvertToYUY2(interlaced=true)

VirtualDub can output 4:4:4 YUV. I've never tried it...

These are mostly 420 , but there are a few 422 sequences here:

I tested VirtualDub's YUV 4:4:4 output and it works. Saving uncompressed gives an AVI file with the fourcc YV24. It's easy enough to locate the three planes of binary data. Here's a 720x480 Belle Nuit chart in raw YUV 4:4:4 (Y=16-235, not suitable for pluge testing):

avisynth 2.6 beta apparently supports yv24 (but I would still wait for official release, I've of heard numerous bugs)

from the changelog

Added formats: YV24, YV16, Y8, YV411.
