Exporting Canon 5D footage from Avid for Comping in Nuke

Hi,

I am doing compositing in Nuke for a film shot on the Canon 5D. The footage was ingested into the Avid at DNxHD 120. The editorial department states that the 5D footage has no timecode, so image sequences must be exported directly from that codec after cutting is completed.

The editor exported targa sequences in RGB color space. However, when I imported the sequences into Nuke, the colours were overly saturated and the blacks were very crushed. It didn’t look anything like the original footage. We also tried exporting targas with a different colour space setting ("605/709", I believe it was called). We got the same results.

The tech in editorial said that this was part of their normal workflow for 5D footage and that we should, quote: "lift the footage by 16" (not sure what he means – haven’t spoken to him directly about this yet).

A colleague brought in a quicktime of the 5D footage and matchgraded the the 5D targa files to it. The grade was a 1.2 gamma lift, I believe. I guess this is a workaround. However, it seems like the wrong way to go about working with files like this.

Can anyone shed some light on this issue, please? What’s the best 5D to Avid to Nuke workflow? Any help would be much appreciated. Thanks.

Roto Keyframes and the curve editor in 6.2v2

I have created a roto shape in Nuke version 6.2v2. I have animated the shape. I tried going to the curve editor to adjust my keyframes and the roto bezier does not even show up in the CE.

I’ve also tried this with a rotopaint node and the keyframes do not show up for that either.

Someone else at work who is running 6.1v2 does not have this problem with the keyframes.

Is this a bug? or is there a setting that needs to be adjusted?

Thanks. 😎

python for modifying color knob on rotopaint

Hi, i was trying to change the color parameter of a rotopaint node. The problem when i use knob(‘color’). It points to color of a selected spline/bezier. How if i want to change the color parameter regardless any selected bezier (i want to use this color for next painting not the existing one). the knob(‘color’) is modifying the color param on the parameter window, this is not i want. I want to change the color parameter which is on the top of the viewer (when the rotopaint is active).

thanx

Nuke keying help

Can anyone please help me in going about keying this shot. I’ve attached a still below. I shot it on a 7D against a blue screen(Taboo, I know), and I can’t figure out how to get good hair detail. I have a couple shots that have this problem, and I’m completely baffled. I even shot clean plates and it does absolutely nothing for me. Any help would be greatly appreciated.

Nuke 6.2 and .3gp files

I am trying to use my android tablet to take some quick shots to practice in Nuke with, and it seems that Nuke does not have a .3gp render plugin. I have some video conversion software (Any Video Converter), but I would really prefer to keep it in the native format if at all possible. My Xoom takes some actually clean video considering what it is, but it is useless to me if I can’t get it into Nuke.

I am trying to prepare for doing a series of effects to mimic those in the show Supernatural and I was planning on using my tablet to do the video shoots as I have 0 money for any other equipment. What is the best way to get all of this to work in concert?

Thanks.

Please Judge me on this Video

Hi all,
I have to create someone driving in a car. I just did a green screen test.
I need some fresh eyes and people to tell me what areas I need to improve on.

I looked at the stills and they looked great but once in motion, I start to doubt myself. Since this is my first green screen car composite, I am very nervous about it.

Also, Rate it 1- 10

1= saturday night live skit and/or 2 drunk friends in basement with a green screen & camcorder.

4=nice but doesn’t fool anyone

10= Production quality

Thanks so much,

Nuke ‘Modeler’ issue

Can anyone tell me why I get an xyz axis show up every time I connect a ‘Modeler’ node to my match moving scene?

I’ve attached a pic to illustrate the scenario.

I just can’t draw any vertices/faces on.

Thanks in advance.
