CF vs. Avid DNx175 10bit vs. Native 7d footage
Here are 3 un-CC'd frame grabs from some test footage.
The Avid was transcoded w/mpeg streamclip and wrapped as MOV. Pulled from Vegas 9.0c timeline. On a 24" Dell 1920x1080 display, the native 7d footage always looks a little sharper and has better color. Why should I stay with Vegas when other NLE's like Edius apparently handle these files natively? |

I don't know that the native footage looks sharper in these grabs, but it does look like you got a gamma shift. I don't know about the CF conversion, but what settings did you use in Mpeg Streamcllip for the Avid one?

Just because you can edit files that are compressed natively doesn't mean you should.
Transcode them to a file format that is less CPU intensive and can handle being rendered and added back to the timeline accordingly without loss in image quality... |

Avid DNxHD>Options button>Color levels RGB>Select 1080/24p DNxHD 175 10bit>quality 100%>Uncheck Interlaced Scaling>Select 1920x1080 unscaled>"Make Movie" The difference is more pronounced on my Dell, though not huge, it really looks like the Avid and CF take a sharpness and color hit. I downloaded Edius trial btw, and native files play not so good, but you can render them quickly and that transcodes them to HQ which is a Grass Valley version of CF. |

Saying that CanopusHQ is the Grass Valley version of CF is implying some things that aren't true. CanopusHQ has a LOT more in common with DNxHD than Cineform.

Otherwise, sorry I can't be of much help with the color shifting issues here.

I will also note that having done DNxHD conversion both inside Vegas and in Avid MC, that the superwhites and blacks were preserved, and I experienced no color degreadation as shown to me on the scopes. I've done those tests with footage from numerous cameras including the Canon 5D.
