Weakness of 8BIT NLE

Hello, I read up and down, and right and left so please explain:

Are we at a disadvantage that vegas is only 8bit, from my understanding that 10bit would be better if you're adding effects and color correction. Others say that even if your material is 8bit you should color correct in 10bit. I was about to switch back to premiere (yuk) just because it supports 10bit. Please explain with little words if you please

thanks
 
There is little visual difference.

Premiere has problems in that the DV codecs tend to clip superwhite information... so I prefer Vegas when it comes to that aspect.

2- FCP is theoretically better, since it has a Y'CbCr pipeline (and goes up to 32-bits). However, it has some image processing bugs, so overall it may not be better.
 
Premiere processes natively in Y'CrCb ever since the first release of Premiere Pro. Shouldn't have problems with clipping super whites as far as I know.

Not sure about FCP.
 
Hmm I just did a quick test.

Its color corrector seems to clip superwhites, which defeats the point of working in Y'CbCr.

2- The waveform monitor does show the superwhites.

I attached my test file in case anyone else wants to try.

3- It may be that Premiere converts from Y'CbCr to R'G'B' internally. Its filters may assume a legal 0-255 R'G'B' range... this increases cross-compatibility with other adobe products + filter architectures.
In other programs, there is really only two flavours of R'G'B' color spaces and no Y'CbCr color space. Well, at least in Photoshop because that's the only SDK I have read.
8-bit R'G'B' blacks at 0, whites at 255
16-bit R'G'B' (effectively 15-bit) blacks at 0, whites at 32768.
