Maybe because they are single channel images 🙂
Just shuffle it back to the alpha channel if you really need them in the alpha channel.
To do a Glare in Nuke you basically key your highlights with a luma keyer and then use a Convolve with a Flare as the convolution pattern. That way you can control the chroma spread and chroma shift using the Flare’s controls.
There was a glare gizmo floating around, try checking http://www.fxshare.com
What kind of vertical streaks are you talking about?
If it’s vertical lines that resemble fields like in the image bellow it’s actually a problem on the telecine as far as I’m aware. I hope it’s not your case, because I end up sending that entire film to retel 🙂
I would say that it’s no excuse for single undo levels though. Single undo level is a thing from ancient times and shouldn’t exist nowadays. And even though it’s something that I might not use I like to know it’s there just in case I need it.
But I would say it’s suites the RGB only nature of Flame though 😉
If all you want is a simple Y axis rotation on the 2D environment just use the “Transform > Card3D”.
You shouldn’t have gamma correction in it by any mean anyway. It’s not an “image” it’s a data pass.
Since you’re using MR you could try using the mip_Motion_Vector shader from MR. I’m not sure it’s packed with Max but probably it is.
Just set it to “Toxik” mode and you should have something that works in Nuke.
RPF is something I’ve used only once in C* right on the beginning and never really bothered about looking at it again. It had some nice things and all but for me both RLA and RPF don’t count as production file formats.
For now you can’t find B-Splines in Nuke, but it has been requested several times and will probably pop-up along with the re-engineered roto tools in a future version.
Yes, completely possible.
Read the docs and take the time to pause the mouse cursor for a moment over each field in a node, all the info you need it’s there. You are getting freeze frames because your before and after dropdowns must be set to “hold”, change them to “black” and you should be fine.

Hi dg,
I’ve played with the settings and I can’t get it to work. The sequence I’m working with is 40 frames long. I want to trim the FG layer to 20 frames, and have it start at frame 20. But, the FG layer just freezes before frame 20 and starts moving at frame 20. I want to see just the BG layer before frame 20, when the FG kicks in.
I’ve tried different settings for the before and after menus but nothing gives me what I want to see. There’s obviously a workflow to this tool, but I don’t think its readily apparent; at least not to me.
I’m confused. :-/
input range 20 – 40
output range 1 – 21Basically the “input range” there is where you trim your source, “output range” is where you “slide” it.
Just take a look at the node’s help by pausing your cursor over each field, and take a look at the chapter 9 of the Nuke pdf doc.
Add a Shuffle node to the “Sam Walk GS.mov” before it being piped to the A input of the merge and set the alpha on this shuffle to constant white (1). This should solve this problem.
Also you don’t need to have the “Bezier1” connected to do it this way. But if you want to, either connect it before the shuffle node or check “replace” on the bezier case you connect it to the shuffle.
You could also just add the bezier (set to alpha only) to the “Sam Walk GS.mov” followed by a premult node and connect that to the A input.
But if I were you, I would look into the AddMix node since this will probably involve a keyer and won’t require any exotic transfer mode.
Web forums don’t cease to amaze me.
You don’t actually have to ‘branch’ all the passes, you can merge and perform almost all the operations from the same reader (pipe) by just selecting the desired layers from the dropdowns and set to which layer you like to output to working in a more ‘inline’ way. But since this may get really messy in some cases you can ‘branch’ them using the Shuffle operator.
Just add a Shuffle set the input layer on the “in 1” dropdown and then to what layer you want to output to in the “out 1” dropdown.
I hope it helps.
Cheers,
