Since I have Avid Media Composer, I also have a bunch of professional-level test patterns that I can send to people.

The patterns I have are made for 16-235. HOWEVER, if you import them into Avid using Computer RGB (0-255) levels, you WILL get inaccurate color (I've seen this personally many times - your blacks will be super intensely crushed). Therefore, they need to be imported into Avid at 601 (CCIR) color (16-235). I know how to do this on Avid, but I'm not sure how to do it in other programs.

I have (at NTSC and PAL SD, and 720p/1080p):

SMPTE Bars
Color Bars
Bowtie
B&W Ramp
Multi-Burst

If anyone wants any of these test patterns, let me know and I'll send them to you.
