No idea! Waiting on an answer to that myself.

The quote was made in person to a friend of mine, who passed it on to me, so no documentation for it, I’m afraid. However, I really trust the opinion of the people who told me, and I’ve heard from other, unrelated industry pros that it looked good.

I’m told https://www.frontniche.com/pdf/tft/46inchHDSDI.pdf matches a Sony HD CRT perfectly, by some BBC engineers.

[Chris Tomberlin] “Adding a chroma smoothing filter to DV captured via firewire brings the chroma smoothness extremely close to that captured via SDI but it is still not “identical”.”
That’s only the case with the simple chroma smoother that Apple provides. You can make them identical, or indeed, as I do, make it better.
The difference is neglibible between SDI and the Apple filtered DV, and is reduced still further from what you’ve shown when you send it back to a 4:2:2 format, rather than viewing as 4:4:4 in FCP.

Yes, applies to mastering back to DV or DVCAM over SDI – you’ll loose quality going that route over firewire. And yes, PAL and NTSC.

Yes, but obviously with a render hit. That’s why I say it’s a workflow issue.
If you’re mastering back to DV though, you’ll loose not just the chroma advantage, but you’ll actually get worse quality if you smooth chroma without it actually being necessary.

Your engineer made an incorrect dub from DV to BetaSP. If the DV deck does not add setup, there are two solutions. One is to use a proc amp, the other is to playback direct from the DV, it being a superior format.
Also, read this paper on video levels, perhaps sending a copy to your engineer?

Capturing DV over SDI doesn’t make it hold up better for colour correction compared to placing DV in a SD Uncompressed timeline. Only difference is the smoothness or not of the chroma – the quality of the chroma, hence dictating applicability for good CC is not altered.
DV or SDI – it’s a workflow choice, not a quality choice.

The full answer is here:

in my white paper on the subject. I think it answers all your questions.

I’ll ask Panasonic and see!
