Clipwrap -VS- 5dRGB -VS- BMD shuttle

[Dermot]

Aside from Avid products which i don't use, is there a recommend reference for DNxHD injest. I'm on Win 64, the DNxHD are wrapped in QuickTimes and i'm using Nuke X and the adobe suite. I believe NukeX defers to the standard QT wrapper - but i don't know for sure. Is it worth transcoding from the QuickTimes and rewrapping the data in a different wrapper? What choices do i have for performing the transcode process?

Avid's decoder is avb in MetaFuze and it's free;

In additional to Dermots perfect example of why a recorder is vital in some post cases, if you have detailed scenes and any movement the built in AVCHD can fall apart very quickly, so whilst you may pull a secondary on a static scene, when that scene or camera moves you may suddenly loose your key because of the compression blocking.

For the price of a BMD there's simply no reason to not go down this route. And i don't have any shares in BMD.

+1 I also don't own shares.. but is was a no brainer for my workflow and projects

Of course, just to most people "heavy grading" seems to involve nothing more than changing the hue and contrast/brightness.

yup... and deliver to highly compressed formats like web and DVD/BR where the laws of diminshing returns kicks pretty fast!

But for others... the sharpness alone is noticably better before gradeing starts...

I'm surprised you mentioned DVD/BR as "heavily compressed" formats...DVD probably yes in that description, but Blu-ray? Just what are you delivering in that's not heavily compressed then?

Here's some more info on the FS100 HDMI port ; I don't know how reliable it is.

I don't know where I went on the website before that I couldn't find the number, but I found the professional contact number for Sony and gave them a call. I got transferred to the technical department and asked about RGB recording. The serviceman asked I hold, and I was on hold for about 8 minutes. After doing his research he came back and explained that this feature is not available on the FS100 but will be on the FS700. So it's official from Sony's mouth, the FS100 is a 4:2:2 YUV camera only, no RGB.

I deliver Movies of the week to A&E, Lifetime, SciFi, Hallmark, CBC on and on.. all delivered on HDSR in 422 AND 444, DCP masters to distrubitiors as uncompressed 16bit .TIFF's

So yea, in the 2,600 gig range for a DCP -vs- 800gig for Sony's SR codec -vs- 25 gig for a BR... seems like BR ends up being 1/1000-ish of the DCP that it is mastered from?

Would you say this is due to the way the BMD handles the information it gets from the camera or would you suspect a similar result from say a DNxHD 220 recorded on the Samurai?

i suspect (strongly suspect i might say) that it's down to the decoder used in your post chain... it seems that both Pp and FCP/FCX are useing the desktop decoder

the recorders are seemingly captureing the camera's output correctly... some software seems to be clearly better than others at unfolding it correctly

DNx is DNx, captured in any device, in Avid software, Samurai, BMD.. but the decoder used, and the decisions it makes is worth questioning

Does it prioritise RT playback at the cost of bit depth, does it clip or clamp, does it change the gamma?

I am OK with Avid's non-RT implementation of DNx, it seems pretty solid, others vary wildly
