Take a look at these color corrected screen caps..

All original .mts AVCHD footage from a Canon 7D. The last two were color corrected in Premiere CS3. Want to know the difference why the last one is holding up better than the other? Remember, these are original 4:2:0 AVCHD clips, not converted.

The first clip is original. The second clip was effected using the "Color Balance (HSL)" filter, the third was effected using the "Fast Color Corrector." The only adjustment made to the two images was saturation. I no longer use the HSL filter for color correction after seeing the difference between these two filters.
 
I don't think that was Keith's point (in which color correction looked the best). I think his point is (and Keith correct me if I'm wrong) that when using the HSL filter you get that weird or strange looking color bleed or pixelation that you see in the second shot but in the 3rd shot you don't see anything but a purposeful change in grading. The outcome is subjective but it shows that the fast color tool does not affect the image in a negative way.

So Keith, it seems you've found the culprit on why you thought the codec wasn't good enough for grading. i think this shows it holds up pretty well. You just have to know which tools to use.

BINGO!

I was simply trying to demonstrate how much better the Fast Color Corrector ( or Three-way Color Corrector), was at boosting certain colors in an image without causing too much degradation to the image quality. These are not final frames from the commercial, just samples I chose to test with.
 
any reference material?

This is taken from Canon's own website: Image Format: Video: MOV (Image data: H.264, Audio: Linear PCM)

Am I missing something here? Where is the user getting .mts files?

Maybe the OP is confusing the HMC 150 with the 7D?
 
Premiere Pro CS4.2 thinks the 7D footage is AVCHD. It recognizes the .MOV wrapper but reads the file as AVCHD. Technically however, AVCHD format's maximum bitrate of 24 Mbit/s is exceeded by the 7D, so even though the 7D .MOV is read as an AVCHD file, there is reason to consider it a hybrid or something. A more advanced implementation of the H.264 standard beyond technical definitions of AVCHD.

Yes, my use of the term "AVCHD" was used loosly. AVCHD by definition simply means Advanced Video Codec High Definition and is a joint venture by Sony (NXCAM) and Panasonic (AVCCAM).

However, that being said, AVCHD utilizes the MPEG-4 AVC/H.264 codec which we all know is used by cameras like the 5D Mark II and the 7D. It's just used in a different way.

Every manufacturer seems to have some different implementation of these newer video formats which makes it hard to define anything, and for Canon's DSLR's it meant no B frames and a higher bit rate in a .mov wrapper.
