AFAIK mjpeg can handle different colorspaces, including YCbCr, so it seems to me that
transcoding video (footage) to mjpeg doesn't necessarily imply colorspace conversion, or
at least a "lossy" colorspace conversion (independently of the loss due to the
codec itself).
Almost any conversion between formats is going to take its toll.
Depending on the transcoder and the involved formats, the level of
impact varies. But how many of those who use DSLRs as their video source
pay attention to the automatically picked ISO level, which has a huge
impact on the noisiness of the image? (Well, I do.) So I think that the
bottom line is each one to his (or her) own source quality, and even
more important, destination quality. If either isn't necessarily high,
transcoding is no big deal, and makes life easier.
If the target is a video in Youtube, quality may not be such an issue.
If it's for national TV, that's a different story.
