[Nuke-users] Default Pixel aspect ratio for Read Nodes
Hi, Is there a way to change the default pixel aspect ratio for read nodes. We use PAL Anamorphic footage a lot and when I drop some footage in Nuke the Read node is set to a standard PAL pixel aspect ratio. I hope there's a solution for this. Regards.

Re: [Nuke-users] Default Pixel aspect ratio for Read Nodes
Hey Donat, Just edit the built-in PAL format to a different pixel aspect and Read nodes will match images that match the PAL resolution to that format. Edit Project Settings... Change PAL from 1.09 to whatever you want. -E On Thu, Jun 23, 2011 at 2:35 PM, Donat Van Bellinghen donat.l...@gmail.comwrote: Hi, Is there a way to change the default pixel aspect ratio for read nodes.

As an alternative, edit formats.tcl. On windows machines, you will find this here: C:\Program Files\Nuke6.2v4\plugins\formats.tcl On Mac, here: /Applications/Nuke6.2v4/Nuke6.2v4.app/Contents/MacOS/plugins/formats.tcl ( This is from memory, I don't have a Mac in front of me ) Inside this file you will notice that 16:9 video formats are listed after 4:3 video formats. Simply cut the 16:9 formats and paste them before the 4:3 ones. Then, Nuke will default to the 16:9 version for both NTSC and PAL.

RE: Re: [Nuke-users] Default Pixel aspect ratio for Read Nodes
Hey Formats.tcl file has nothing to do with Reader's aspect ratio. This is only list of names of formats in Nuke, created for users convenience. Reader set up format based on info about resolution and aspect ratio of file. Then Nuke compares the format with the formats.tcl and if format has a name, Nuke uses this name. Thats all. If you remove standard PAL (1.09) format from the list, Nuke will create new unnamed format. I guess that you have problem with quicktime files. The actual problem is inside movReader in Nuke, which in some cases can't read out actual aspect ratio from quicktime file. Its worth to say, that sometimes this information is not saved in mov files.

Re: Re: [Nuke-users] Default Pixel aspect ratio for Read Nodes
Formats.tcl file has nothing to do with Reader's aspect ratio. It does when there's more than one format defined with the same resolution, and the file does not contain metadata of its pixel aspect. In that case, Nuke will set the format of the Read to the first format in the list that matches the file's resolution, with whatever pixel aspect is defined in that format.

Re: [Nuke-users] linear to AlexaV3LogC math
Hi They never look great - colour wise, (content wise can be fantastic). In the past I've found its the conversion from their mov(?) file - (nothing to do with quicktime movs) that can go screwy. Usually you can get better results going back to that and reconvert.

Re: [Nuke-users] linear to AlexaV3LogC math
Yes proper conversion from .cine Phantom file is key. Ned try loading the files in to Frame cycler. It can read the .cine file native. This will help you see if the color is wrong or right in the files delivered to you. Randy S.

Re: [Nuke-users] linear to AlexaV3LogC math
Randy, All I have from the client at this point are DPX frames, so I will ask if we can get our hands on the .cine file. Good to know that it works with FC, thanks for the tip!
